Does spanning tree still work when you put it in that way?
Testing is the best way to find out. In the second example, you are only
filtering based on the DSAP value. But the question becomes whether it is
an assumed '00' for the SSAP, or whether you just aren't paying attention to
those entries. So.... Do your switches still do spanning tree if you do
the second one.

Subject: mac access-list question
When you configure:
mac access-list extended ESAS
permit any any lsap 0x4242 0x0
in a 3550 switch, you are allowing STP packets. You specify the destination
and source SAP (0x4242). Would be also valid to issue only 0x42:
mac access-list extended ESAS
permit any any lsap 0x42 0x0
Would both MAC ACL's accomplish the same function?
Thanks for the help
