Displaying Pnni Summary Addresses - Cisco MGX 8850 (PXM1E/PXM45) Configuration Manual

Chapter 2 Configuring General Switch Features
Step 3 To change the SPVC prefix, enter the following command:
mgx8850a.7.PXM.a> cnfspvcprfx -prfx <prefix>
Replace prefix with the 13-byte prefix you want to use. For example:
mgx8850a.7.PXM.a> cnfspvcprfx -prfx 47.00918100000100001a531c2a

Step 4 Verify the correct entry of the prefix by entering the dspspvcprfx command.

Displaying PNNI Summary Addresses

After you configure the PNNI level, peer group ID, ATM address, and SPVC prefix, review the summary
addresses the node will advertise. If all PNNI parameters are properly coordinated, the node should
display a single summary address that represents all PNNI destinations in that node. To display the
summary addresses, enter the dsppnni-summary-addr command as shown in the following example:
mgx8850a.7.PXM.a> dsppnni-summary-addr
node index: 1
Type..............
State............. advertising
Summary address........47.0091.8100.0001.0000.1a53.1c2a/104
The example above is coordinated with the examples in the previous sections, so just one PNNI summary
address is broadcast to the peer group. The following example demonstrates what happens when the node
ATM address and the SPVC prefix are not coordinated:
mgx8850a.7.PXM.a> dsppnni-summary-addr
node index: 1
Type..............
State............. advertising
Summary address........47.0091.8100.0000.0000.1a53.1c2a/104
Release 5.0.10, OL-3845-01 Rev. B0, August 16, 2004
The SPVC prefix in the example above matches the first 13 bytes of the node PNNI address
example presented in the previous section, so PNNI can advertise one prefix to support both SVC
connections through the node and SPVCs. If the SPVC prefix does not match the corresponding
bytes in the ATM address, PNNI advertises two prefixes instead of one. The SPVC prefix should
conform to your ATM address plan. For more information, refer to the Cisco PNNI Network
Planning Guide for MGX and SES Products.
The SPVC node prefix for each node must be unique within the network.
