Managing the PNNI table includes:
• Viewing PNNI information.
• Changing PNNI configuration parameters.
• Editing the PNNI summary table.
Viewing PNNI information
The PNNI information table displays node information. To view PNNI information:
1 Open the Configuration menu and select PNNI Info . The PNNI Information
window appears.
Figure 8.4 PNNI Information
The PNNI Information window provides node information, such as Node Level, Node
ID, Node ATM address and Node Peer Group ID. You can update the Node Level and
Node Peer Group ID.
You may wish to change the peer group ID, if you notice that multiple switches you
have on the network have different peer group IDs, and are not connected successfully.
Changes made to the fields in the PNNI Information window will only take affect after
the switch is reset.
Note: Changing the node level, changes the first byte of the peer group ID, and the
first byte of the Node ID.
For a full description of the fields in the PNNI Information window, refer to Appendix
B, Configuration Fields.
Editing the PNNI Summary Table
The PNNI specification defines that each PNNI node advertises the addresses that are
locally connected to it. Since it is not possible to specify that each node advertises all of
its local Reachable Addresses (RA), PNNI defines a way that the node advertises
summaries of its Reachable Addresses. For the lowest level node, the ATM address of a
switch is the switch default summary, as all directly connected hosts and edge devices
