Chapter 2 Configuring General Switch Features
Configuring PNNI Node Parameters
Setting the PNNI Node ID
The PNNI node ID appears in many CLI displays, including the dsppnni-node command display. The
default node ID is PNNIlevel:160:defaultATMaddress. If you change the PNNI level or the node ATM
address, you should also change the node ID so that the node ID represents the correct PNNI level and
ATM address. This will make it easier to identify the node when using CLI commands because most CLI
commands reference the node ID, not the node ATM address. For example:
mgx8850a.7.PXM.a>
dsppnni-link
node index : 1
Local port id: 16848897 Remote port id: 16848897
Local Phy Port Id: 1:2.1:1
Type. lowestLevelHorizontalLink Hello state....... twoWayInside
Derive agg........... 0 Intf index........... 16848897
SVC RCC index........ 0 Hello pkt RX......... 22366
Hello pkt TX......... 22178
Remote node name.......8850_SF
Remote node id.........56:160:47.00918100000100036b5e31b3.00036b5e31b3.01
Upnode id..............0:0:00.000000000000000000000000.000000000000.00
Upnode ATM addr........00.000000000000000000000000.000000000000.00
Common peer group id...00:00.00.0000.0000.0000.0000.0000.00
In the example above, there is no reference to the ATM address for the remote switch named 8850_SF.
However, if the node ID is set to match the ATM address, it will be easy to determine the ATM address
of a remote switch.
To set the PNNI node ID, 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:
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 node ID is configured at the lowest PNNI level, so replace <node-index> with 1.
Note
The node ID you enter at the lowest level is used for all levels. PNNI uses a modified version of
the lowest level node ID for upper level nodes.
Step 3
Change the PNNI node ID with the cnfpnni-node command as follows:
mgx8850a.7.PXM.a>
cnfpnni-node
<
node-index>
[-nodeId
PNNIlevel
:160:
atm-address
]
To configure the lowest PNNI level, replace <node-index> with 1. Replace PNNIlevel with the lowest
PNNI level, and replace atm-address with the 20-byte ATM address you want to use. For example:
mgx8850a.7.PXM.a>
cnfpnni-node
1 -nodeId
56:160:47.00918100000100001a531c2a.00001a531c2a.01
Step 4
Enable PNNI node operation by entering the following command:
mgx8850a.7.PXM.a>
cnfpnni-node
<
node-index>
-enable true
Replace <node-index> with the value you used when disabling and reconfiguring the PNNI node.
