2948G-L2 %SYS-4-P2_WARN: 1/ScxSwitchMan

-05:00 %SYS-4-P2_WARN: 1/ScxSwitchMan: Protocol Table Packet on

address 00:10:7b:ab:99:6f arrived on unexpected port

Does anyone know/seen this error before, and is this common? I have seen this message with several macs flapping, in my logs. I have 2-2948Gs trunked to each other and each trunked to router. I also have several 2950s (aggs) uplinked to these 2948Gs, that are seeing a ton of incrementing ignored link errors on the uplinked ports. During the time of these errors, it is locking up/killing my switches, and the only solution so far has been a reboot. Then everything appears to be ok, until it happens again. It has happened about 3 times now, over the last 4 days. Any help or suggestions appreciated.

Take a look at the following bug

I suggest that you upgrade to 6.3(10) as it has lot more enhancement and open a TAC case if you see any similar messages
