We have C6513 with Dual Sup 720 + MSFC3. There is one HSRP group configured on about 30 VLANs. On all the VLANs the HSRP shows that primary MSFC is the active and the second MSFC is standby except one group which shows active on both.
You probably don't have an active path for that vlan between both 6500's .If so then both sides will think they are supposed to be the active side . What switch does the one vlan run thru ? Also check authentication passwords if any are used. Normally it is setup like this.
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...
