Hi there,
Wondering if anyone can help here with an issue I have with adding a PIX standby firewall to a network design. When I configure power on the PIX firewall standby performance on the LAN drops considerably. This is notable when pinging LAN switches from the Primary PIX, receive several pings and then drops and pings again. I'm quite sure that I have the firewalls configured correctly, Primary unit Active and Standby unit Standby, would I have a possible spanning tree issues causing the performance degradation.
Note: spanning tree configuration on cwnocsw01 and cwnocsw03 are the same:
spanning-tree mode pvst
With the priority set the same for all vlan's on both switches?
i.e. spanning-tree vlan 100 priority 24576
Any tips or advise much appreciated.
Regards,
Michael.
