I wonder if you can help me....
I have two 6513's running IOS with FWSM's. Everything was fine for a long time until one switch decided to reboot.
I got it running again and I now have a problem that applies only to the switch that rebooted (even tho both are almost identical in config).
What's happening it seems is that any traffic on VLAN1 of that switch is being flooded out of all VLAN1 interfaces, even tho the MAC-address-table knows where everything is. The other switch doesn't have the problem and is working as expected.
I do see something strange in the mac-table -- it's a mac 3333.0000.000d that says it's static that has assigned itself to every port and every VLAN. However this is seen on the switch that isn't flooding as well so it may not be the problem.
Does anyone have any ideas as to why this could be happening - it's really slowing things down for certain critical machines here and I'm a bit stuck for ideas.
Please ask for any other info you may require to help.
Thanks in advance
