This document outlines how to setup the Link Aggregation between the Brocade FCX and the VDX series of switches. On the FCX equipment you will setup Link Aggregation on the Interfaces. On the VDX equipment you will setup Port Channels.
Use the same Port-Channel numbers on both VDX switches to make them participate in a Virtual Link Aggregation (VLAG). This example is setting up Port-Channel #10 on two VDX switches. Po10 is being configured to run on interface 1/0/5 and 2/0/5. The Po10 interface has to be setup as speed 1000 also to match the FCX side.
