DLSw+ port lists map traffic on a local interface (either Token Ring or
serial) to remote peers. Port lists do not work with Ethernet interfaces, or
any other interface types connected to DLSw+ by means of a bridge group. You
can create a port list of local ports and apply the list to remote peer
definitions. Traffic received from a remote peer is only forwarded to peers
if the input port number appears in the port list applied to the remote peer
definition. The port list command provides a single command to specify both
serial and Token Ring interfaces. Figure 130 shows how port lists are used
to map traffic.
DLSw+ ring lists map traffic on specific local rings to remote peers. You
can create a ring list of local ring numbers and apply the list to remote
peer definitions. Traffic received from a remote peer is only forwarded to
the rings specified in the ring list. Traffic received from a local
interface is only forwarded to peers if the input ring number appears in the
ring list applied to the remote peer definition. The definition of a ring
list is optional. If you want all peers and all rings to receive all
traffic, you do not have to define a ring list. Simply specify 0 for the
list number in the remote peer statement.

Subject: DLSW Port list vs. Ring list
Please pardon my ignorance, but can someone please explain when to use a
port list and when to use a ring list. If using TR can you use both? Any
explanation and/or config examples would be appreciated. Thanks.
