Quickstart Provisioning Procedures
XPVC and XPVP Configuration Quickstart
AXSM/A, AXSM/B, and AXSM-XG cards support both an Extended Permanent Virtual Connection
(XPVCs) and an Extended Permanent Virtual Paths (XPVPs). An XPVC/XPVP is basically an
SPVC/SPVP that connects a PNNI network to an AutoRoute network.
XPVCs and XPVPs span over AutoRoute-PNNI or AutoRoute-PNNI-AutoRoute hybrid networks. Each
XPVC/XPVP can contain up to five segments that support various combination pairs of Frame Relay,
ATM, and RPM endpoints. Each XPVC/XPVP may contain feeder nodes such as the Cisco MGX 8220,
Cisco MGX 8230, Cisco MGX 8250, and Cisco MGX 8850 (PXM1).
The UNI or NNI interface on each XPVC segment is enhanced and called either an Enhanced
User-to-Network Interface (EUNI) or an Enhanced Network-to-Network Interface (ENNI). The
EUNI/ENNI allows segment OAM loopback cells to start from an edge of the hybrid AutoRoute-PNNI
network and traverse through the multiple XPVC segments.
Note Cisco recommends that you use the CWM application to set up multi-segment OAM loopback. The
OAM segmentation capability supports fault isolation in the AutoRoute-PNNI network.

Define the virtual trunk signaling at each core edge node. Select
no trunk signaling by setting the -univer option (UNI ports) to
none or the -nniver option (NNI ports) to none.
See the “Selecting the Port Signaling Protocol” section on
page 3-44.
Step 15
Follow the steps in the
“Configuring SPVCs and SPVPs”
section on page 3-54.
For each virtual trunk, configure an SPVP between the virtual
trunk ports at each edge of the core network.
Step 16
cc Change to the PXM card.
Step 17
dsppnni-reachable-addr
network
Verify PNNI connectivity between the two nodes that will host the
virtual trunk end points.
See the “Verifying End-to-End PNNI Communications” section on
page 4-54.
