Chapter 2 Configuring General Switch Features
Configuring PNNI Node Parameters
The switch displays a report similar to the following example:
mgx8850a.7.PXM.a>
dsppnni-node
node index: 1 node name: mgx8850a
Level............... 56 Lowest.............. true
Restricted transit.. off Complex node........ off
Branching restricted on
Admin status........ up Operational status.. up
Non-transit for PGL election.. off
Node id...............56:160:47.00918100000000001a531c2a.00001a531c2a.01
ATM address...........47.00918100000000001a531c2a.00001a531c2a.01
Peer group id.........56:47.00.9181.0000.0100.0000.0000.00
Setting the PNNI Node Address
The Cisco PNNI Network Planning Guide for MGX and SES Products provides guidelines for setting the
PNNI node address, which is identical to the switch ATM address. To set the PNNI node address, use
the following procedure.
Caution
When installing new switches, you can assume that each default node address will be unique. When
PXM cards are repaired or moved between switches, however, it is possible that two switches will start
using the same node address. To prevent duplicate node addresses, use your own address plan, and check
the node address whenever a PXM card is replaced or moved from one switch to another.
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:
mgx8850a.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. The node index is a reference to particular logical PNNI process in the node.
The PNNI address is configured at the lowest PNNI level, so replace <node-index> with 1.
Note
The PNNI address you enter at the lowest level is used for all levels. PNNI increments the
selector byte (which is the last byte) of the ATM address to represent logical nodes at higher
PNNI levels.
Step 3
Change the PNNI address with the cnfpnni-node command as follows:
mgx8850a.7.PXM.a>
cnfpnni-node
<
node-index>
[-atmAddr
atm-address
]
To modify the PNNI address at the lowest level, replace <node-index> with 1, and replace atm-address
with the 20-byte ATM address you want to use. For example:
mgx8850a.7.PXM.a>
cnfpnni-node
1 -atmAddr 47.00918100000100001a531c2a.00001a531c2a.01
