Surprised one is working even after reading the docs requirements , it needs to be on lanbase not lanlite

Creating Named MAC Extended ACLs

You can filter non-IPv4 traffic on a VLAN or on a Layer 2 interface by using MAC addresses and named

MAC extended ACLs. The procedure is similar to that of configuring other extended named ACLs.

Note MAC ACLs are supported only when the switch is running the LAN base image.

Hi Mark, 

Thank you very much!!!

But we do not find lanebase image for this PID: WS-C2960-24TC-S

Hi

looks like that platform cant be upgraded at all to base version

https://supportforums.cisco.com/discussion/11664351/cisco-2960-tc-s-lan-lite-lan-base

Hi Mark, 

Please find attached file..

As given in diagram the requirement is like Host 1 should not be able to communicate with other host from LAN and vice versa but host 1 should be able to communicate with router interface and to server across MPLS network.

We are applying below mentioned mac access-list to the switch port on which Host 1 is connected.

Mac access-list extended Test

Permit host ( Host 1’ s mac address) host ( Router f0/0 mac address)

Permit host ( Host 1’ s mac address)  ffff.ffff.ffff 0000.0000.0000 ( Broadcast)

Deny host ( Host 1’ s mac address) any

After applying access-list to the port on which Host 1 is connected. Host 1 is able to communicate with the server and router f0/0 interface and communication within the same LAN is getting blocked. But after few minutes Host 1 starts to communicate with the other hosts from the LAN which should not happen. Please suggest further..

Hi

if its not supported anything could be causing it not to work right in the software itself , im not going to suggest anything as if it was my network I wouldn't even attempt to put something in place that's not supported in the documentation as you could end up with anything happening triggering some other issue ,  ive been there before its caused me nothing but hassle I would avoid it and get something that supports it if you really need it or block it layer 3 or use some other filter method

this is the 2nd doc now saying its not supported too , first doc was version 15 for 2960s this is your 12.2.55 train also stating it

http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960/software/release/12-2_55_se/configuration/guide/scg_2960/swacl.html#pgfId-1289037

Hi, 

Could you please suggest how we can prevent a particular MAC from branch end but can from server end.
