giant packet on Vlan

Hi,

This message was logged on the syslog by a Cat6000 switch with MSFC2.

%MSFC2-3-TOOBIG: attempt to send giant packet on Vlan2 (184 bytes from 72F8D9A)

-Traceback= 30259844 301C99D4 302C6218 302B8CA8 302B9A54 302B83F0 302B85EC 302B8778 301F49F4

Users belonging to this vlan were not able to reach the hsrp ip address of this vlan while this message was received.

On resetting the switch , the connectivity was restored and the message stopped.

What could cause such a problem ?

The message refers to packets of about 180 bytes in size which arent really gaint frames. Also what does the value "72F8D9A" in the message refer to ?

Thanks,

RZ

I am not sure about this particular error. But Traceback messages usually reflect an error in the operating system code. I would suggest that you look in the Cisco Bug Toolkit for the particular version of code running on the switch and see if there are any bugs identified which sound like this one.

Depending on how often this happens and how severe the impact it, you might also consider upgrading the code to a more recent version and see if that fixes the problem.
