One or two LAG port-channel for 5508 v7.4 in HA setup?
I have a question regarding LAG in HA setup; do you configure two port-channel, one for each controller or, only one port-channel for both?
I have a stack of 3 x 3750x, and 2 x 5508 with each two Gigabit uplink in use. Active controler (5508-1) is connected to stack switch 1 and stack switch 2. Standby controller (5508-2) is connected to stack switch 2 and stack switch 3.
I cannot find any documentation or guidelines for configurations of LAG in HA setup.
P.S. my question is not how to configure LAG or LACP, it only if you use one port-channel consist of 4 gigabit ports, or you have two with each 2 gigabit port to each controller.
