dual cisco cisco sup32 10ge 3b. Does uplink failure trigger standby sup
Posted on 2011-02-27
I have a couple of 6509e switches each with cisco sup32 10ge 3b installed.
Each sup32 has 2 - 10gb ports.
I would like to know if I use one of the 10GB ports on the primary sup for a trunk uplink to the core and one 10gb ports from the standby sup as a trunk uplink to the core will I have redundancy if the uplink fails on the primary sup. I.e. - if the uplink port goes down on the primary sup goes down will this trigger the standby sup to become active or do I need to utilize both 10gb ports on each sup and create a portchannel to protect myself against a single point of failure?
