Okay, so we did a recovery on our 6509 last night which appeared to go well. I currently have 10 vlans on the 6509 all with seperate dist switches on each subnet...Now traffic across all subnets work fine except I no longer seem to be able to access my switch IPs anymore. Unless I am local to that subnet.
We did reboot the 6509 several times but none of the subnet switches were touched.
I tested one switch by rebooting and it appeared to fix the problem. Possible Arp cache problem ? Any thoughts ? I can reboot them all tonight but would like to know the cause..From the active MSFC I can ping all switch IPs, but not from the 6509 switch console.
Each floor is a Vlan which has a 3548 on it. The 3548 is trunked back to the 6509 via fiber and yes the uplink ports on the 6509 are trunked (isl).
The management IP of each 3548 is in the local subnet of the floor vlan..Ex.10.1.3.0 /24 is vlan 3 and the switch IP is 10.1.3.2. The trunk links back to the 6509 are working fine as all users per floor have connectivity out of their vlan. So each 3548 appears to be switching fine.
A bit more info...It appears that I have 2 floors working as far as switch management however when I look at their arp cache for their default gateway, the MAC is of router 16 on the slot2 MSFC which should be in standby. All the other vlan switches that dont work, have the MAC of the Slot 1 MSFC.
