The reason I ask about this is that I'm currently playing around with mac
access-lists on the 3550's
The task is to make one vlan IP only and run is-is as the routing
protocol...
So I permit ip, ether type 0x806 0x0 (IP ARP), and lsap values 0xfefe 0x0
(IS-IS) and 0x4242 0x0 (STP)
then I create a vlan access-map out of all those statements, add a drop
statement in the last clause, and apply it to the vlan.
R6 is connected to SW1, SW1 is connected via trunks to SW2, and SW2 is
connected to R5.
All is fine after I apply it to SW1, but as soon as I apply it to SW2 I
start getting this on R5:
*Mar 1 09:08:59.721: %AMDP2_FE-6-EXCESSCOLL: Ethernet1/0 TDR=1, TRC=0
Rack2R5#
*Mar 1 09:09:05.601: %CLNS-3-BADPACKET: ISIS: LAN L2 hello, Duplicate
system ID detected from 0002.16d4.3fd1 (Ethernet1/0)
