Howdy everyone,
I am having an arp problem on one of my switches, a cat 6509. (Technically I suppose it would be with the MSFC...)
Here's my setup:
M$ Cluster(Vlan1) --> 6509ios 6509cat --> Users(Vlan2)
The switches are flat, both have all Vlans. 6509ios is the gw for Vlan1 and 6509cat is the gw for Vlan2.
We have an M$ cluster set up and being tested, we found that during a failover the systems on the same VLAN seem to be okay with picking up the new MAC address fairly quickly, they miss one ping, but crossing VLAN's does not work until I clear the ARP cache in the switch.
It would appear as if the cluster sends a grat arp and the 6509ios recieves it but the 6509cat never see's it. I'll try to hit it with a sniffer later to be sure.
