Problem applyinh Mac address filtering on 2621-XM Router, IOS 12.2

[mhchin]

Hello,

I am using a CISCO 2621-XM Router running IOS 12.2.

I am trying to block a particular mac address using

access-list 701 deny 000b.cda7.c8f3

I tried applying the following to router's interface

interface fastethernet 0/0

bridge-group 1 input-address-list 701

Did not work!

access-expression input smac(701)

Did not work either!

Have I missed something?

Thanks in advance.

Michael

1.In Transparent Bridging , with input-address-list under the interface, filtering is done based on the source address of the incoming frame. ACL 700 is used for matching mac-addresses. For wild card masks, 0 is exact-match and 1 is do not care. (Holds good for SRB also. The wild card mask should start with 0x8. to match the RII in the SRB frames).

2.In TB, with output-address-list under the interface, filtering is done based on the destination address of the outgoing frame. ACL 700 is used for matching mac-addresses. For wild card masks, 0 is exact-match and 1 is do not care. (Holds good for SRB also.)

So may be it will work if you apply a out-address-list 701 .

Hello vmoopeung,

Thanks for suggestion.

Tried the out-address-list 701 but still no filtering was achieved.

The Mac address to be block is a internal LAN Lap-Top user.

Regds,
