Can someone help with VLANs?

CANIndiana — Wed, 04 Nov 2009 13:38:17 GMT

Our network has 200+ devices on it right now but it's flat, well we have different subnets, but still using basic switches. At various points in the day we notice extreme congestion and some reliabilty problems. I want to create VLAN's so that traffic isn't broadcast across the whole network unnecessarily, and hopefully that will increase the performance and decrease the other problems we're having.

The only problem is that I don't know how to create the VLANs. I managed to get the switch set up so that get to the web interface and I've been looking through the options but I'm stuck other than that. I understand that the VLANs need a trunk to pass information to each other and that without the trunk no other VLAN can communicate to it. So it might be best to explain the situation and then maybe someone can tell me what I need to do based on that.

I have 3 subnets: 192.168.0.x, 192.168.1.x, and 192.168.2.x

The servers, Zyxel VPN router, and a Windows box set to act as a router, and about 100 devices are on the 192.168.0.x subnet

About 70 devices are on 192.168.0.1 subnet and another 50 or so devices are on the 192.168.0.2 subnet

Everyone needs to communicate with the servers, some people have shared folders on their computers so I don't know if that will be an issue or not, and some of the servers have multiple NICs with an IP on each subnet and I'm certain that complicates things as well.

So, having said all that can someone help me?

About to drive my car over this 2724 Switch.

Tolahouse — Sun, 22 Nov 2009 20:10:52 GMT

I am trying to setup VLAN Trunks on ports 1-8 to talk to VLANS 50, 60 and 70 from ESX hosts. These VLANS will also have ports 23 and 24 as Trunks to the internet/firewall but I'm not getting anywhere.

I also want to setup ports 9-14 as VLAN Trunks for VLANS 80 and 90 for VMotion while also having access to the ESX Console using another port.

I have tried tagging and untagging, changing PVID's, admitting all and not admitting all but I must be getting a lot wrong because its not working.

Could somebody please put me in the right direction. Please.

Thank you.

PowerConnect 2808 problems

This may sound like a stupid question, but how do you make the initial connection to the 2808 internal serial port?

How to add a vlan via SNMP? PowerConnect 5448

dsaasd46 — Thu, 24 Sep 2009 11:53:30 GMT

Hello,

After hours searching i am stuck, can someone help me with adding a vlan via SNMP?

Some things i tried:
"This is quite simple using the MIB dot1qVlanStaticRowStatus (OID 1.3.6.1.2.1.17.7.1.4.3.1.5.2), to create vlan 2 use 1.3.6.1.2.1.17.7.1.4.3.1.5.2 -i 4"

Simply if i do this, there is no effect and the vlan will not added in the switch.
Also, if i try to edit an exsisting vlan, i cannot change the value.

Can someone help me out?

Changes in VLAN configuration for Powerconnect 6224 Firmware 2.2.0.3

StorageNet — Tue, 17 Nov 2009 09:50:22 GMT

Is there any change in configuring PowerConnect 6224's L2 VLAN in Firmware 2.2.0.3?

In firmware 1.0.2.6 I can interconnect 2 x PowerConnect 6224 with 2 separate ISLs in 2 VLANs by using the General mode and PVID set to 4095.

but after upgraded to 2.2.0.3 it seems that mechanism does not work anymore. It could be caused by a new VLAN setting in 2.2.0.3

Does anybody have the information about the changes?

Thanks

PowerConnect 2848 not applying DHCP obtained address after reboot?

twinsen12 — Wed, 11 Nov 2009 22:38:47 GMT

Hi all,

we seem to have a problem with our newly acquired PowerConnect 2848 switch. We want it to be in managed mode, and to get its IP address from a DHCP server.

When booting the switch we can see that it gets the address, but then it won't apply it to the running configuration. We have to go to the web console, and check the "Apply DHCP settings" checkbox, so that it effectively uses the settings it got from the server. Everything is fine and well until the next reboot of the switch, where it will once again request an IP, and it will fail to apply it.

Is there any way to work around this problem?

thanks

powerconnect 6248 jumbo frames

6248.study — Wed, 07 Oct 2009 03:51:16 GMT

Hello:

We had a stack of three powerconnects 6248 connected to form a single managed rack unit (identied as unit #1, #2 and #3 when u login to console).Unit #3 was configured for jumbo frames for all GE/10GE ports when all three were mounted/bundled together.

I have taken one of the three 6248s out, and would like to use this 6248 as a single standalone switch. Even though, I had configured all ports of this 6248 to support jumbo frames, I'm unable to pass traffic >1500B via this 6248 when operating it as a single standalone switch...

It appears that the jumbo frame setting got erased or something when this 6248 was removed from the stack of three 6248s...

Can someone please let me know how can I verify (or re-configure) if the jumbo frames are supported on this standalone 6248.

Thanks a lot!

5324 - Help with VLANs to block traffic from connected network, specifically DHCP

OptiChip — Mon, 16 Nov 2009 16:06:50 GMT

I currently have a 5324 Switch connecting my office with another, is there a way to block DHCP traffic on a specific port or VLAN?

port 1 connects to some switch that is shared by both offices

port 2-8 are machines on my network that have a default gateway of 192.168.240.1 ( All of these machines need to connect with a cisco router through port 1 )

ports 9-24 are machines on my network that have a default gateway of 192.168.240.33 ( All of these machines have their own internet connection through port 24)

I was thinking if I setup 3 different VLANs that it'd do the trick but I'm kinda lost on what to do here.

Current Config:

jumbo frames. Powerconnect 5424

Peter_1780 — Mon, 16 Nov 2009 14:09:45 GMT

I have some interoperability problem between pc5424 and extreme networks. I have connected few pc 5424 via trunk port 802.1q to black diamond 8k.

I see some packet loss, about 1% on nfs. When i flood via icmp, 1000 pkt/s, the loss is about 5 packets. Of course bigger problem for me is nfs..

All switches work in L2 only, i don't see any options for jumbo on pc5424, what is size of ethernet jumbo frame ?

On extreme switch i have: Jumbo: Enabled, MTU= 9216,

All servers have:

ipmtu: 1500
size jumbo frames: 9000

When i connected only two pc5424 everything works ok..

someone had similar problem ? thanks You for some advice

greetings

PCT5324 64bit SNMP

umekoro — Wed, 15 Sep 2004 05:37:41 GMT

I found that PCT5324 doesn't have a 64bit snmp counter.It means PCT5324 doesn't support 64bit snmp. Is there any plan to add a 64bit snmp counter in a next new firmware ?

Please let me know asap.

Strange Dell 6248 behaviour during a power down and power up

Templar3k — Wed, 11 Nov 2009 13:36:13 GMT

The Dell Switch, 6248, was powered down during work on the electrical systems in the building.

Once that switch was powered on nothing came back online and a technician was dispatched to find out what the problem was.

When logging on in console the reason became clear. The configuration on the switch was simply lost, parts of it seemed reminiscent of configuration done during the initial setup of the switch almost a year ago. Since then the config has been changed to include OSPF, over 20 new Vlans added and several other optimization and changes.

One could at this point think that the configuration hasn't been saved and so the device was reverting back to the configuration it had stored in the Flash memory. That is not the case, the configuration has been saved during every change or addon.

After the conguration backup was restored the switch back online, it's a core in one location, we powered down the switch 3 times to see if it would fail in any way. It did not fail and came back online as espected.

We're simply stunned by this switch behaviour and it's very important for us to get some kind of possible explanation as this switch is a core for about 400 users and servers and a hub device in a larger topology.

The Switch has the latest version 2 image loaded.

Your ideas and thoughts are appreciated.

Dell PowerConnect series LAG & LACP configuration

ryanmoat — Mon, 09 Nov 2009 19:22:56 GMT

I am having trouble understanding how Dell's LACP works with LAG. I mean, I do understand, but let me explain my situation. I have started at a company which has several Dell PowerConnect switches. Each floor has a core Dell switch and they all have LAG enabled on the switch. We have two newer models (Dell PowerConnect 5448 & 5324), and then some older models (PowerConnect 2748 & 2824).

The 5448 & 5324 support LACP to aggregate the ports to a LAG. However, the company is using LAG configurations between all of these switches. So between the newer models and the older models, LAG is enabled, but it is impossible to enable LACP.

What is the advantage of having all the switches have LACP enabled on the LAG configurations? Is there a problem enabling LAG between the two with LACP? Of course the 5448 & 5324 have both LACP & LAG enabled. I guess I am asking, what is the difference between having LACP enabled and not having it enabled? Especially since this network is mixed with some supporting both (which are enabled), and then the newer and older switches setup on with LAG (since LACP is not supported on the older models).

Powerconnect 5324 locating a MAC in the address-table

Kiel1 — Mon, 27 Jul 2009 19:08:30 GMT

I am currently looking for a way to find which port a specific MAC is plugged into. "show bridge address-table" will list all MACs but there seems to be no way to filter it. I wrote a script to log in via telnet and search the list but the output is paused and waits for user input. I cannot find a way to deal with this or find a way around it and am only getting the first page of MACs.

Does anyone know of a way to do this for this model of Powerconnect?

Thanks a lot.

RPS LED on 6248 question

trentg — Mon, 02 Nov 2009 17:46:49 GMT

I have some overheating 6248's. They each have an RPS-600 attached. The RPS's all have 4 LED's on the front numbered 1-4. Some of these are blinking green constantly. I can't find any explanation for these LED's in the RPS or switch manuals. Please advise. Thanks.

5424 web gui versus running-config versus startup-config

sf3wire — Mon, 02 Nov 2009 21:12:06 GMT

I have a 5424, and after some restarts and relocations, I'm finding a lot of the changes I make in the web gui are missing from the startup config.

Am I just missing something here? As an example, I set the default IP gateway in the web gui, and click the Apply Changes, it takes effect immediately. If I then hit the CLI and compare the show running-config against the show startup-config, the default gateway setting is missing!

So I'm finding myself going to the cli and doing a "copy running-config startup-config" everytime I'm messing with the GUI, which seems silly...anyone else experiencing this?

powerconnect 5448 and 2848 port enabling

As I am new to this type of work, I need to know how to "enable" five each ports on these power connect units. The 5448 appears to be ready, as I hook a computer to the lines, they become active. However, the 2848 is for voip phones, and are not enabled into the network? or are shut off.

PowerConnect 3548P ports bouncing - link up/down

schris403 — Wed, 28 Oct 2009 00:52:47 GMT

Over the last month or so we have been having some network issues as it relates to ports going down and up all by themselves. The messages are like this:

12 2147483646 27~Oct~2009 05:27:46 Warning %LINK-W-Down: 1/e22

This will continue randomly and the ports stay only down for about 2 seconds as you can see above. I have started over on the configuration by loading defaults and still no luck. Users have been reporting that their computers are loosing link every once in awhile. I have two 3548P switches in a stack and both switches have this occur. Any ideas what would be causing this? Does the configuration file look ok below? Thank you for anyone's help!

Create a Vlan

ramant — Tue, 27 Oct 2009 23:28:38 GMT

Guys,

Have a basic knowledge of create a default vlan. Need some help with creating vlan Current scenario is

Running AD with DHCP enabled. Address range is 10.0.0.1 - 10.0.0.254. Subnet mask 255.255.255.0 ; Power connect swithces : PC5324 and PC6248

Issue : running out of IP's.

I am assuming that I have create subnets. If i create a new subnet how do I assing this subnet range to a Power connect 5324 switch and ensure they can talk to other switches. Does anyone have a set of steps to do this..

Thanks

Raman

How do you manage your PowerConnect configs?

STLTHX — Tue, 27 Oct 2009 18:53:15 GMT

I'm just curious how do you all manage your Dell PowerConnect configs?

If a change is made to a switch how do you copy the updated config and to where?

Is the process manual or automated? If so, how?

Thanks.

Question about Stacking on 6224

njecm — Tue, 20 Oct 2009 18:39:44 GMT

Is it possible to do port-channel groups across 2 6224s without using the stacking module?

ie: can we team/stack the switches using one of the fiber or gige ports?

the goal is to have 2 core switches (6224) use vrrp to make them redundant and connect 1 port from each server to each switch, so if one fails everything will remain up and running.

I'd also like to do this on our isolated ISCSI network.

I guess what I need to know is do we NEED to purchase the stacking modules? Or is it possible (albeit slower) to "stack" with one of the slower interfaces?

Moved our office and changed ISP Need help setting server back up

KimMattox — Mon, 26 Oct 2009 01:10:58 GMT

We recently moved our PowerEdge 840 & PowerConnect 2708. We changed ISP's from AT&T to comcast due to HSI availability.

I am unable (novice admin obviously) to bring the server back on line. I am not sure where to change the static ip. All the computers (and the server) are able to connect to the internet, but unable to access the server. I have two network adapters on the server. Any help would be greatly appreciated!!!

SonicWall NSA 240 to 6224 issue.

RightSpin — Fri, 23 Oct 2009 03:29:40 GMT

This has been whoopin me for a week now. I feel like I've got everything right on the Dell switch, and that the problem probably lies in the SonicWall, but I need to be sure before I escallate the issue with them. I can access the SW correctly from the 200 VLAN but none of the others. Intra VLAN routing is fine on the switch side.

Here is my 6224 config. The SW connects to 1/g1. Any help is greatly appreciated.

5324 problem - SWINIT-F-INITPORTLIB: SW2C_dist_new_master_id:: Port lib init failed

blue-dot — Thu, 02 Mar 2006 23:19:44 GMT

When I power on my switch, I get the following error message:

SWINIT-F-INITPORTLIB: SW2C_dist_new_master_id:: Port lib init failed

Is there anything that I can do to fix the switch or perform some sort of reset function?

Thank you,

6248 Switch Redundancy and LACP (LAG) NICs

Eddiie — Wed, 03 Dec 2008 07:15:10 GMT

Hello,

I'm looking to eliminate single point of failures in my network setup... All Dell servers which have dual NICs, I plan to run one NIC to one switch and the other NIC to the second switch and configure them as a 802.11ad (I think it is) group. I get my LAG and LACPs mixed up so please forgive me.

Looks like we are limited to 24 LAGs - is this correct? Is there any way around this? 24 servers max in this configuration.

How do I configure LAGs across switches? I'm using Dell Powerconnect 6248's.

What is the perferred switch configuration for this scenario? Cluster/stack them? 10GB Uplink them together?

How do other people do this?

thanks!

Power Connect 6248 Stacking Question

b.hailes — Tue, 20 Oct 2009 09:31:14 GMT

We have a couple of the PC6248 switches and are currently unstacked, we are thinking of stacking them together using the CX4 cables and modules for the switches,

The main thing we are concerened with is switch reboots,

when the stacking cables are plugged in to the swithces do they reboot?

I have been reading around and cant find a conclusive answer to whether they reboot or not, we cant reboot the switch as its a production switch, we'd rather use the CX4 cables and modules instead of having to use a cross over cable to join the switches together as that can potentially cause us lag in the network.

Any advice would be appreciated

6224 Radius Authentication broken

seefriek — Thu, 11 Oct 2007 00:45:57 GMT

I've got a recently added 6224 running 1.0.4.3. I've configured it to use Radius to authenticate administrators against a Microsoft IAS server. I use this identical configuration to authenticate 6024F and 52xx switches in the network. This is the standard config off of the Dell web site. However, when admins log into this switch and successfully authenticate (IAS events show no problems), they are logged in at priv-lvl 1, not priv-lvl 15. No amount of mucking about gives me the answer I need to fix this.

OSPF VLAN routing problem on PC6248

6248 Stacking (or not) in VMware iSCSI implementation

Chuck Citrano — Tue, 06 Oct 2009 21:40:09 GMT

I am purchasing (2) 6248 Switches to use in my VMware implementation and cannot figure out if stacking is the right way to go. I plan on making all the traffic on these switches dedicated to iSCSI

Here is the simple config and redundancy requirements:

1. On the ESX Server there are 2 NICs that are bonded together by ESX.

2. I want to plug one NIC into one 6248 and the other NIC into the other 6248.

3. I will either use the stacking module to create 1 logical switch or I will use a 10GB module and create a LAG.

I've read through the forums and it seems that the stacking offers some convenience, but it also causes some issues with availability when upgrading firmware or if the Master falls off.

Does anyone have practice experience on how best to configure this. My original plan was to create a stack and then add additional 6248's into the stack as I needed more iSCSI ports.

Thanks in advance.

Chuck.

PowerConnect 5324 and NLB

STLTHX — Wed, 14 Oct 2009 16:33:54 GMT

I've been perusing the forums here and I am still not sure what the consensus is regarding NLB (Network Load Balancing) and the Dell PowerConnect 5324 switch.

My question is this: I want to place two Dell PowerEdge servers in a NLB array using Microsoft's Network Load Balancing.

The functionality that I am looking for is for the two 5324 ports to send the same data to the virtual IP's MAC address so that the NLB algorithm can process the request.

In addition, what is the procedure(s) to get two ports to forward the same frame to both ports participating in the NLB array?

Connecting two PowerConnect 62xx switches w/ stacking cable vs 10GbE uplink module

pzero — Thu, 23 Jul 2009 08:18:41 GMT

Hi,

We've currently have two PowerConnect 6248 switches stacked together. Besides other things, we use it for our iSCSI SAN with VMware Virtual Infrastructure 3.5: each ESX Server has one iSCSI port connected to the first switch and another iSCSI port connected to the second switch for redundancy reasons.

We've recently upgraded the switches to the latest firmware version 3.x (and also to the new boot code), following the procedure in the Dell release notes, and that caused both switches to reboot together.

The stack took about two minutes to come back online and for all that time our iSCSI SAN was unreachable, bringing down the VMware VMs. Please also see my other post here with more info: http://en.community.dell.com/forums/t/19284196.aspx

If I got it correctly, there is currently no way to upgrade the firmware for stacked switches and avoid the single reboot for the whole stack (and the associated network downtime for all the equipment connected to the stacked switches).

So in order to avoid the VMware Virtual Infrastrucuture downtime with our current setup when upgrading the PowerConnect firmware (or when doing other maintenance to the switches), we are now considering to change the switches configuration and to use the two switches separately instead than a stack.

Is there any way to have the two switches still connected by the stacking cable but act as two separate switches (so you can update the firmware for one of them at time) instead of a single logical switch?

Or would we need to use a couple of ethernet ports on each switch to create a LAG to connect them? Or better yet can we purchase a 10GbE uplink module (for CX-4 Copper, dual integrated ports) for each switch and use that to connect the two switches and manage them separately?

If not using the two switches as stacked, besides losing the convenience of managing them together from a single console/web interface and the losing the high bandwidth connecting between the two, would we lose anything else if we manage them separately and connected them through the 10GbE uplink modules?

Thanks.

Is there any downtime when stacked PC6224 switches failover ?

johndoe99 — Sun, 18 Oct 2009 04:05:35 GMT

Hi,
I'm trying to find out how two Powerconnect 6224 switches behave when stacked together for a iSCSI SAN.
From what I have read, in a stack, there is one Master and the other a standby. If the Master fails it takes some time to failover to the standby switch.
This could be fatal for the running Virtual Machines on the ESX hosts as they would loose connection to the SAN storage.

Could someone explain if the above is correct ?

Or should the two switches be setup as stand alone, with paths to each switch from the storage and hosts, which would mean in case of failour of one switch the other one keeps working and hence no downtime.

Thanks for any info.

What happened to the PowerConnect 62xx v3.0 firmware?

antsman — Fri, 18 Sep 2009 21:51:07 GMT

What happened to the PowerConnect 62xx v3.0 firmware? It was there a couple of weeks ago, but it's gone now. I just got a new PowerConnect 6224 and was going to upgrade it, but the firmware is gone.

Thanks for any information anyone has!

PowerConnect switches and multicast performance

mastersingh — Thu, 15 Oct 2009 16:01:34 GMT

I have 2 different PowerConnect switches - a 2716 and a 5324 and am experiencing very bad performance when using Tibco RV which uses multicast under the covers.

When I run tests using another switch (for example a dumb 8 port Netgear hub), I see orders of magnitude difference.

It is unclear to me what the correct parameters to set are in order to optimize for high volume multicast traffic.

In my case, 12 out of the 16 ports would have servers plugged in that are subscribing to the RV multicast data

Best practice for "uplink" ?

Patrick B. — Tue, 06 Oct 2009 13:35:30 GMT

Hi,

I've 3 poweredge switches (one 5424, one 5324 and one 5448). The 5324 and 5448 are connected to the 5424 with a single cable.

And today i had an idea... Creating LAGs to use multiple cables to link the switches, and having an uplink between the switches of 4Gbs rather than 1Gb.

So, on the 5424, I created 2 LAGs of 4 ports each one, and on the 5324 and 5448, I created one LAG of 4 ports. I removed the old uplink cables, plugged the 8 new ones.

First impression : it works.

Second impression : It doesn't work.. Many paquets were lost, and into the switches log files, i saw many and many ports down and up, STP forwarding, ...

So is there a well known way to do this ? My idea was not good ? I missed something ?!

Thanks for you help, regards

Patrick

Port mirroring on PowerConnect 6248

brian975 — Wed, 07 Oct 2009 23:14:37 GMT

I'm trying to set up a web filter for our company.

We have a PowerConnect 6248 that is the core switch. The main router is on port 45 and the firewall is on port 44. The filtering server is on port 10.

the configuration I have is:

monitor session 1 destination interface 1/g10
monitor session 1 source interface 1/g44
monitor session 1 source interface 1/g45
monitor session 1 mode

According to the documentation, this should be correct. However, when I run a packet sniff, all I see is the local interface and the switch that it's connected to.

What am I doing wrong?

Cable diagnostics for copper SFPs

jrakov — Mon, 17 Aug 2009 18:28:33 GMT

On our distribution Powerconnect 6224F, some ports are populated with copper SFPs. In 2.x.x.x firmware it was possible to get cable diagnostics for these ports the same way as for standard copper ports. After upgrade to 3.0.0.8, the switch refuses the commands and web gui offers cable diagnostics only for ports 21 - 24. Is the feature no longer supported in 3.0.0.8?

trunk port 2748

bvifsc — Tue, 06 Oct 2009 19:41:22 GMT

I have a 2748 switch with two vlans. Ports 1-24 are in VLAN1 and ports 25-48 are in VLAN2. I have the switch uplinked to another device on port 23, but VLAN2 traffic cannot get to it because that port would need to turned into a trunk port. Is there anyway in which I can turn it into a trunk port? what are the steps I would need to do to turn it into a trunk?

How to configure PC6248 and PC5424 to allow Microsoft NLB and prevent switch flooding

RolandN — Wed, 07 Oct 2009 14:07:11 GMT

Hi All,

We want to enable Microsoft NLB on a number of servers. To prevent switch flooding we are consider enabling NLB multicast mode with IGMP. Can someone please specify which configuration changes should be made (and to which switch)?

A highly simplified view of the network:

[server_1] --- [PC5424_1] === [PC6248] === [PC5424_2] --- [server_2]

The servers participating in the NLB cluster are configured in the same VLAN. The PC6248 is configured to allow VLAN routing. Systems from other VLAN's should also be able to access the NLB cluster.

Thank you.

6224 QinQ SOLVED

chris.bowman — Thu, 26 Mar 2009 22:40:45 GMT

I've a customer with a trunking 20 VLAN's to port 1 on my 3524, I've setup the 3524 as switchport mode customer (QinQ) on vlan 1000, I have a trunk from my 3524 to a 6224 which contains this vlan 1000, at the 6224 I wish to strip the outer QinQ tag, and send it out to a router which has multiple vlan subinterfaces matching the vlans of the cusomters trunk.

So for example lets say :

Customer Switch (Trunk VLAN 2-21)=> Dell 3524 E1 (QinQ on VLAN 1000) <=> 3524 G1 (TRUNK VLAN 1000) => 6224 G1 (TRUNK VLAN 1000) <=> 6224 G24 (Need to strip outer tag 1000 here) => (Trunk VLAN 2-21) Router

From what I can tell, the 6224 to my surprise only supports what you guys call "DVLAN-Tunnell", which would allow me to tunnel a QinQ tagged frame THROUGH the switch but not allow me to strip it at the switch, and send the vlans contained within to a device directly connected to the 6024.

If this is correct, then why on the Technical Specs for this switch does it clearly say QinQ which is 802.1ad, it seem's the 6224 does not support 802.1ad ? My hope is I've overlooked something, and will be promptly corrected! :)

Thanks in advance!

PowerConnect 5424 between PowerVault and PowerEdge

bushtor — Fri, 02 Oct 2009 12:14:27 GMT

Hi,

We are in the process of connecting two PowerEdges iSCSI vise to a dual controller PowerVault across two 5424 switches for redundancy.

The PW boxes has 3 dual port NICs, two of these are used for iSCSI. The iSCSI comms works fine, but as I use only the last four of each 5424's 24 ports I wonder if I can use some of the remaining ports to untag VLANs from VMWare ESX in the PowerEdge boxes.

I wonder if I can set the 4 first ports to Trunk type and assign VLAN tags 10,11,and 12 to these. Then set ports 5-8 as untag VLAN10, 9-12 as untag VLAN11 and finally untag 13-16 as VLAN12. All these ports have VLAN type General and not the default Access type. What are your comments to using a 5424 for dual purposes (iSCSI and ethernet) like this?

iSCSI want Jumbo Frames for optimum data speed, and I have set this option and reset the switch. However would Jumbo Frames be a disadvantage in my case since I also use regular ethernet switching and not only iSCSI?

Should I alter other settings in these switches to optimize in my scenario?

Thanks for comments and tips

best regards Tor

Dell PowerConnect 6248P: Enable VLAN 1 in Trunk Mode

jbloomhart — Wed, 22 Oct 2008 05:40:45 GMT

I just received a Dell PC 6248P and our environment is in the middle of transitioning to a vlan'd environment. However, we still have a lot of devices in VLAN 1 and this works fine with our PC 3xxx models.

However, if I attempt to make a trunk port on the 6248P, it automatically removes vlan 1 as being able to traverse the port:

interface ethernet 1/g17
switchport mode trunk
switchport trunk allowed vlan add 100
switchport trunk allowed vlan remove 1
exit

This is a new behavior with the 6248P as it works fine with our 3448P. Is there any way to correct this? I recognize that it's not ideal to have devices on the management vlan but until we complete the migration, it's necessary.

The end picture should be:

Port is set to trunk

When you look at the port it should show:

VLAN 1: U

VLAN 100: T

Instead mine currently shows:

VLAN 1: <BLANK>

VLAN 100: T

Thanks!

6624s + VLANs + vSphere

mrockwe — Thu, 01 Oct 2009 17:30:34 GMT

(I am not a strong "networker" so some of these questions will seem common sensical to many but I will appreciate your patience & guidance nonetheless)

--------------

Scenario: (2) 6624s connected to (2) R610's containing (6) NICs + (1) EQL PS5000. Default switch config. Goal is to VLAN the switches into (3) subnets:

192.168.10.x = Production/Public/VM traffic (VLAN10)

192.168.20.x = Management (ESX service console + dedicated Management port on PS500) (VLAN20)

172.16.9.x = iSCSI traffic (VLAN30) Jumbo frames enabled on these physical ports & NICs + "Dell PS5000 on vSphere" install guide was used to set up vSwitches with Jumbo frames, etc. which is working perfectly

192.168.1.1 = Linux-based Internet firewall & default gateway for current, flat production network

--------------

Each server is cross connected to each switch and port2 has ISL between switches

Plan to set up VLAN by groups of physical ports (i.e., ports 2-9 = VLAN10, 10-15 = VLAN20, etc.)

--------------

I am guessing I will need to reassign IP of firewall (default gateway) to be 192.168.10.1 (for Production traffic)

QUESTIONS:

1. I wish to access the Management network (192.168.20.x) from my workstation on the 192.168.10.x network. Do I need to set up VLAN routing to accomplish this? Does the Linux firewall become the "default gateway" (192.168.10.1) for this VLAN routing?

2. Does the ISL on VLAN1 (g2 to g2 on each switch) connect the VLANs on each switch or does each VLAN need its own ISL?

3. Should I enable flowcontrol on the switches?

Again, any help or guidance that can be offered is greatly appreciated.

VLANS on 2824 Power Connect - Trunk ports advice please !

enesem — Thu, 01 Oct 2009 15:18:54 GMT

Hi. Some questions as we're not familiar with Dell switches...

I have a 2824 switch, and I want to configure VLANS. From the web interface, I have created the VLANS and then in VLAN membership, changed the port to show "T" for the ports I want to be a member of that VLAN. I have ports 23 and 24 I want to allocate as trunk ports, is there anything additional that needs to be done to designate that or does it happen automatically once you make the port a member of multiple VLANS ?

I am going to replicate this congiguration to a second switch for load balancing, they will connect to eachother via the trunk ports.

Also, has anyone any advice on setting up the LAG's ?

Any advice gratefully recieved.

Many thanks.
