Bridging and IBM Networking Configuration Guide

To enable filtering on input or output, use one of the following commands in interface configuration 
mode:

You can filter SNAP-encapsulated packets on either input or output. The access list you specify is 
the one you created that includes the protocol type codes. 

To enable filtering on input or output, use one of the following commands in interface configuration 
mode:

Filter Frames by Vendor Code

To configure administrative filters by vendor code or address, define access lists that look for Token 
Ring addresses or for particular vendor codes for administrative filtering. To do so, use the following 
command in global configuration mode:

Filter Source Addresses

To configure filtering on IEEE 802 source addresses, assign an access list to a particular input 
interface for filtering the Token Ring or IEEE 802 source addresses. To do so, use the following 
command in interface configuration mode:

Filter Destination Addresses

To configure filtering on IEEE 802 destination addresses, assign an access list to a particular output 
interface. To do so, use the following command in interface configuration mode:

source-bridge input-lsap-list access-list-number

Enable filtering of IEEE 
802-encapsulated packets on input by 
type code.

source-bridge output-lsap-list access-list-number

Enable filtering of IEEE 
802-encapsulated packets on output 
by type code.

source-bridge input-type-list access-list-number

Filter SNAP-encapsulated packets on 
input by type code.

source-bridge output-type-list access-list-number

Filter SNAP-encapsulated frames on 
output by type code.

{permit | deny}

Configure vendor code access lists.

source-bridge input-address-list access-list-number 

Enable filtering on IEEE 802 source 
addresses.

source-bridge output-address-list access-list-number

Enable filtering on IEEE 802 
destination addresses.
