Description dave brooks 1999-12-09 18:22:40 UTC
we are experiencing problem with systems using intel nics causing multicast
storms and impacting other systems on the network. It appears to drivers or
features on the nic that are enabled -

Comment 1 dave brooks 1999-12-09 19:34:59 UTC
here is more detail on the issues

Destination Address 01-80-c2-00-00-01
Source Address (address of the NIC
Ethertype 8088
Frequency 0.84seconds

Hex Dump of the mulitcast packets
01 80 C2 00 00 01 00 A4 00 80 D2 9C 88 08 01
40 00 00 00 00 00 00 00 00 00 00 00 00 00 00

00 00 00 00 00 00 00 00 00 00 00 00

This is a problem with the Intel "eepro100" driver. The problem appears to occur
when the system is halted but not turned off.

The frame in question is a flow control frame and is never generated by a linux
kernel.
Due to lack of documentation from intel on eepro100 configuration/setup its not
possible to guess what the post Linux shutdown/bios issue might be.
