The definition of a port list is optional. If you want all peers and all interfaces to receive all traffic, you do not have to define a port list. Simply specify 0 for the list number in the remote peer statement.

To define a port list, use the following command in global configuration mode:

Command

Purpose

 

 

Router(config)# dlsw port-listlist-number type

Defines a port list.

number

 

 

 

Note Either the ring list or the port list command can be used to associate rings with a given ring list. The ring list command is easier to type in if you have a large number of rings to define.

DLSw+ Bridge Group List

DLSw+ bridge group lists map traffic on the local Ethernet bridge group interface to remote peers. You can create a bridge group list and apply the list to remote peer definitions. Traffic received from a remote peer is only forwarded to the bridge group specified in the bridge group list. Traffic received from a local interface is only forwarded to peers if the input bridge group number appears in the bridge group list applied to the remote peer definition. The definition of a bridge group list is optional. Because each remote peer has a single list number associated with it, if you want traffic to go to a bridge group and to either a ring list or port list, you should specify the same list number in each definition

To define a bridge-group list, use the following command in global configuration mode:

Command

Purpose

 

 

Router(config)# dlsw bgroup-list list-number

Defines a ring list.

bgroups number
