We have a core Avaya 882 switch that will soon be replaced with a 6513 switch. Currently the Avaya switch is connected to Avaya 330 and Cisco 3750 edge switches. I have 802.1Q trunking setup.
I was wondering about 8021Q nonnegotiate mode. With the current core Avaya switch. Should my 3750 be set to nonnegotiate? Do not see that option on the Avaya core switch. Interesting that one stack of 3750s is using nonnegotiate and an another is not. I tried to change the nonnegotiate off on the one stack but the stack uplink went down and didn't come up till I went back to nonegotiate.
When I place the 6513 as our core how do I want to setup the trunking mode from the 6513 to the 3750s.
