Viewing PNNI information
The PNNI information table displays node information. To view PNNI information:
1Open the
Configuration
menu and select
PNNI Info
. The PNNI Information
window appears.
Figure 9.4 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 devices 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 device 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 device is the switch default summary, as all directly connected
hosts and edge devices that use ILMI for address registration get the switch prefix as
the prefix to their address.
To view the PNNI Summary Table:
1Open the
Configuration
menu and select
PNNI Summary Table
. The PNNI
Summary Table appears.
