Network Management
There are several network management tools available to the user to help them more easily manage and
troubleshoot their DLSw+ network. CiscoWorks Blue Maps provides a logical view of the portion of
your router network relevant to DLSw+ (there is a similar tool for RSRB and APPN). CiscoWorks Blue
SNA View adds to the information provided by Maps by correlating SNA PU and LU names with DLSw+
circuits and DLSw+ peers. CiscoWorks Blue Internetwork Status Monitor (ISM) support allows you to
manage your router network from the mainframe console using IBM’s NetView or Sterling’s
SOLVE:Netmaster. See the DLSw+ Design and Implementation Guide “Using CiscoWorks Blue: Maps,
SNA View, and Internetwork Status Monitor” chapter for more details.
Traffic Bandwidth and Queueing Management
Cisco offers several bandwidth management and queueing features (such as DLSw+ RSVP) to enhance
the overall performance of your DLSw+ network. The queueing and bandwidth management features are
described in detail in the DLSw Design and Implementation Guide “Bandwidth Management Queueing”
chapter.
Access Control
DLSw+ offers the following features that allow it to control access to various resources throughout a
network:
• DLSw+ Ring List or Port List, page 307
• DLSw+ Bridge Group List, page 308
• Static Paths, page 309
• Static Resources Capabilities Exchange, page 309
• Filter Lists in the Remote-Peer Command, page 309
DLSw+ Ring List or Port List
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.
To define a ring list, use the following command in global configuration mode:
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.
Command Purpose
