Cisco Multiservice Switching Networks

MGX-8950 also contains the PNNI controller in the PXM-45B controller card. The configuration steps for an MGX-8950-based PNNI node bringup and interface configuration are the same as in the MGX-8850 PNNI node we explored in the preceding section. For that reason, not every configuration command is repeated in the following sections.

PNNI Node Bringup: PXM-45-Based MGX-8950

The internal PNNI controller in the MGX-8950 switch looks like Example 10-24.

Example 10-24. Displaying the PNNI Controller Details

m8950-7b.7.PXM.a > dspcontroller m8950-7b System Rev: 03.00 Feb. 20, 2002 03:16:52 GMT MGX8950 (JBP-2) Node Alarm: MAJOR Number of Controllers: 1 Controller Name: PNNI_8950 Controller Id: 2 Controller Location: Internal Controller Type: PNNI Controller Logical Slot: 7 Controller Bay Number: 0 Controller Line Number: 0 Controller VPI: 0 Controller VCI: 0 Controller In Alarm: NO Controller Error: m8950-7b.7.PXM.a >

The final PNNI configuration for the network is as displayed in Example 10-25.

Example 10-25. Displaying the PNNI Configuration Details

m8950-7b.7.PXM.a > dsppnni-node node index: 1 node name: m8950-7b Level............... 64 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...............64:160:47.000000000000010002008950.0004c113ba46.01 ATM address...........47.000000000000010002008950.0004c113ba46.01 Peer group id.........64:47.00.0000.0000.0001.0000.0000.00 m8950-7b.7.PXM.a >

The steps to achieve this PNNI configuration are like those for the other two PNNI nodes.

Configuring PNNI Interfaces

After bringing up pnport 5:1.1:1, you have a lowest-level horizontal link in twoWayInside state. That link faces the MGX-8850 PNNI neighbor, as shown in Example 10-26.

Example 10-26. Using the Command dsppnni-neighbor

m8950-7b.7.PXM.a > dsppnni-neighbor node index : 1 node name : m8850-7a Remote node id: 64:160:47.000000000000010002008850.00309409f6ba.01 Neighbor state: FULL Port count.......... 1 SVC RCC index....... 0 RX DS pkts.......... 3 TX DS pkts.......... 2 RX PTSP pkts........ 3 TX PTSP pkts........ 3 RX PTSE req pkts.... 1 TX PTSE req pkts.... 1 RX PTSE ack pkts.... 1 TX PTSE ack pkts.... 1 m8950-7b.7.PXM.a >

Both MGX-8850 and BPX-SES PNNI nodes' summary addresses are network-reachable. See Example 10-27.

Example 10-27. Using the Command dsppnni-reachable-addr

m8950-7b.7.PXM.a > dsppnni-reachable-addr network scope............... 0 Advertising node number 2 Exterior............ false ATM addr prefix.....47.0000.0000.0000.0100.0100.8600/104 Transit network id..
