I have two 6509's using WS-SUP720-BASE (supervisor engine).
The ROOT bridge for all our vlans are split across the two switches.
Vlans are load balanced over the two switches and each vlan is
monitored through HSRP. For example: -
vlan 100 priority 8192 vlan 100 priority16384
vlan 200 priority 16385 vlan 200 priority 8192
vlan 100 vlan 100
HSRP active HSRP standby
vlan 200 vlan 200
HSRP standby HSRP active
If any vlan on 6509-2 is up and in an active state then the HSRP virtual ip and vlan addresses stop
responding to requests from other networks. To get around the problem I have had to change the HSRP
priority of all vlans on 6509-1 to make them all active.
Any ideas whats going on?
Thanks in advance.
