This guide covers configuring a Virtual Link Trunk (VLT) between two C9010 switches. This includes creating a Link Aggregation Group (LAG) and configuring the appropriate port channels between the Cisco Catalyst 3750 and the two C9010 chassis. Virtual Local Area Networks (VLANs) are then created to divide the network into logical segments. Before configuring the VLT, Spanning Tree Protocol (STP) considerations are discussed. Instructions are provided to enable Per-VLAN Spanning Tree Plus (PVST+) on the C9010s and Rapid Per-VLAN Spanning Tree (Rapid-PVST) on the Cisco Catalyst.
