Background: Two Cisco 6509 chassis in the same rack, set up as a stack, so a port from one reads 1\3\27, from the second it reads 2\9\27 for example.
What i have been told is that these are redudandant and if the one chassi fails it can somehow cope with that failure but i do not understand how, if a connection for a server goes into 2/9/27, and if the stack with 1/3/7 fails. How would it cope up. but anyway back to my main question.
I would like to set up a 4 LACP for (as this is a stack?) fotr 8 datamover ports on EMC celerra.
How do i do this? also should i consider using Etherchannel, Pagp etc?
Please guide ?
I am happy to post any output from the switch if it will help answer my question.
