Chapter 2 Configuring General Switch Features
Configuring PNNI Node Parameters
To display the PNNI controller configuration, enter the dspcontrollers command:
8850_LA.7.PXM.a > dspcontrollers
Setting the PNNI Level and Peer Group ID
The Cisco MGX and SES PNNI Network Planning Guide provides guidelines for selecting a PNNI level
and peer group ID. To set these parameters in the switch, use the following procedure.
Step 1 Establish a configuration session using a user name with SUPER_GP privileges or higher.
Step 2 Disable PNNI node operation by entering the following command:
8850_LA.7.PXM.a > cnfpnni-node <node-index> -enable false
The node-index uniquely defines a logical PNNI node within the switch. Initially, there is just one logical
PNNI node at the lowest PNNI level, and its index number is 1. If you add a higher level logical node to
the physical node, the first higher level will be numbered two, and the next higher level will be number
three. Additional levels receive sequentially higher node index numbers.
During this general node configuration, you are setting the PNNI level and peer group ID for the lowest
PNNI level, so replace node-index with 1.
Note For instructions on creating logical nodes above the lowest PNNI level, see Chapter 6,
“Managing PNNI Nodes and PNNI Routing.”
Step 3 Change the PNNI address with the cnfpnni-node command as follows:
8850_LA.7.PXM.a > cnfpnni-node <node-index> [-pgId level:peerGroupID]
To configure the lowest PNNI level, replace <node-index> with 1. Replace level with the PNNI level you
want to use, and replace peerGroupID with the 13-byte peer group ID you want to use. For example,
8850_LA.7.PXM.a > cnfpnni-node 1 -pgId 56:47.00.9181.0000.0100.0000.0000.00
Step 4 Enable PNNI node operation by entering the following command:
8850_LA.7.PXM.a > cnfpnni-node <node-index> -enable true
Replace node-index with the value you used when disabling and reconfiguring the PNNI node.
slot 7 Slot number for PXM45 cards. Enter 7 or 8 to specify the PXM45 as the
PNNI controller host.
cntrlrName text Controller name. This parameter is optional. You can enter a text name
to identify the PNNI or MPLS controller. If the name you want to use
includes one or more space characters, enclose the entire name with
quotation marks.
