Currently have two 3750x stacked with 15.1.SE1 code. When doing a rolling stack upgrade, we lose ip connectivity to the VLAN layer 3 interfaces on the stack for about 20-40 seconds after the 1st switch restores and takes over master. Stack has dual trunks(one to each switch) to a router with EIGRP. Is this normal behavior during rsu upgrade?
One note...in the logs after the reload, I can see where the VLAN interfaces go down and recover. Code is doing a micro code/firmware update, not sure if that has any effect.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
