Hi,

Sorry for disturbing your question but I just want to verify whether access
expression can work in Ethernet? As far as I know it only works in Token
ring environment.

Thx a lot!

Hi consider the following diagram:

ETH LAN A--(R1)----(IP CLOUD)----(R2)--ETH LAN B

There is a DLSW connection between R1 and R2... Say I wanted only to allow
only SNA frames to go from LAN A to FEP on LAN B (non-canonical MAC
1111.1111.1111) and I had to use an access expression on R1's Ethernet
Interface (other requirements ommitted)...

When I build my access expression, would I use the non-canonical or
canonical
MAC address in my access-list for the DMAC entry??

I would have thought I would use the NON CANONICAL representation as the
access-expression sits on the interface before the traffic hits the DLSW
process (where it gets bitswapped)... I have however, documentation that
provides a different take on the situation...

Joe
