Cisco 6513 Bug (was Re: hey had eric sent you

Yep, we had to send in the line cards to get them
upgraded, didn't have any information on upgrading the s/w
on the Line cards and TAC wanted me to RMA them back. So.
Boy this one was a real pain because it only seemed protocol
specific at the time.
Here's the referenced Bug for those interested.

Packets destined out the WS-X6548-GE-TX or the WS-X6148-GE-TX that are
less than 64 bytes will be dropped. This can occur when a device forwards a
packet that is 60 bytes and the 4 byte dot1q tag is to added to create a valid
64 byte packet. When the tag is removed the packet is 60 bytes. If the
destination is out a port on the WS-X6548-GE-TX or the WS-X6148-GE-TX it will
be dropped by the linecard.
Additionally, if packets are received on an interface that does not have a
minimum MTU of 64 bytes (e.g. ATM,POS) and are destined out the WS-X6548-GE-TX
or the WS-X6148-GE-TX it will be dropped by the linecard.
No current workaround other than moving the recieving device to a different

Bit hard by same bug. What version of code are you running on the 6513
8.1(2) fixes the bug on the 6x48 line cards. What happens is that packets
of 64 bytes or less are silently dropped. Replacing linecards will not
help unless there is another bug of which I am not aware. With a little
digging I can dredge up the relevant DDTS.
