Quickstart Provisioning Procedures
XLMI Link Configuration Quickstart
An Extended Link Management Interface (XLMI) link joins a PNNI network with an AutoRoute
network. After you establish an XLMI link, you can configure connections that link CPE in the PNNI
network with CPE in the AutoRoute network. The interconnection of PNNI and AutoRoute networks
enables network expansion beyond the limits of AutoRoute. It also facilitates a gradual migration from
an all AutoRoute network to an all PNNI network.
Note XLMI links are not supported on MGX 8950 switches or AXSM-E cards.
To establish an XLMI link, you need to perform the following tasks:
1. Configure an AXSM port for the XLMI link.
2. Configure a BXM port for the XLMI link.
3. Create a connection between a destination on the PNNI network and a destination on the AutoRoute
network.
The procedure in this section describes how to configure an AXSM port to support an XLMI link, and
references the instructions for creating a connection between the PNNI and AutoRoute networks. Before
you begin configuration, consider the following guidelines and limitations:
• XLMI cannot be provisioned on a port which already has connections provisioned. To change the
port to XLMI, you must first delete all existing connections.
• The control VC for LMI uses VPI = 3 and VCI = 31. These numbers are not allowed on other types
of connections.
• Each AXSM or AXSM/B card supports a maximum of 16 links to AutoRoute networks and feeder
nodes.
• Each AXSM or AXSM/B port can support one link to an AutoRoute network, so the maximum
number of links to AutoRoute networks is equal to the maximum number of physical AXSM ports.
• XLMI links support SPVCs and SPVPs. SVCs and LVCs are not supported.
Step 9
cnfenhiisp - optional Optionally, you can configure enhanced IISP using the cnfenhiisp
command on the PXM controller. Refer to the Cisco MGX
8800/8900 Series Command Reference, Release 5.2 for a
description of cnfenhiisp.
Note The cnfenhiisp command only works if the link is up and
running.
Step 10
cc Change to the AXSM card.
Step 11
addaddr Add destination addresses to each end of the trunk.
See the “Defining Destination Addresses for Static Links” section
on page 3-60.
Step 12
addaddr Add static addresses to destination ports. This step is required
when addresses are not dynamically assigned to the CPE at the
destination ports.
See the “Assigning Static ATM Addresses to Destination Ports”
section on page 3-46.
