Connection Capacities of the AXSM
The SVC and SPVC connection capacities for the front card, back card, and physical lines appear in
Table 6-2
Nevertheless, the tables provide these maximums when you plan the use of commands such as
addrscprtn, addcon, and any other command where you may want to know the capacity of the
configured item to support connections.

Identifying Physical and Logical Elements
The Private Network-to-Network Interface (PNNI) control protocol and the service modules use
different formats to identify the same entity. For example, the format of a logical port that you enter on
an AXSM is different from the format you would enter on the PXM45. This section describes these
formats in the PNNI and AXSM contexts and how they correspond to each other. The parallel actions of
configuring or displaying logical elements on different cards is broadly illustrated in the Cisco
MGX 8850 Routing Switch Software Configuration Guide, Release 2.0.
