Connection Capacities of the AXSM
The SVC and SPVC connection ca pa cities for the front card, back card , a nd physical lines appear in
Table 1 -2 and Tabl e 1-3. The capacity o f a single AXSM card is greater th an th at o f th e n o de it self.
Nevertheless, the tables provide thes e m ax im u ms wh en y o u p la n th e u s e of c omm ands such as
addrscprtn, addcon, and any other command where yo u m ay wa nt to k n ow the ca pacity of the
configured item to support con nec ti on s.
Identifying Physical and Logical Elements
The Private Network-to-Network Interface (PNNI) control protocol and the s erv ice modules use
different formats to identify the s ame entity. For example, the format of a logical po r t th at y ou en ter o n
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 the y corre spo nd to each othe r. The parallel actions of
configuring or displaying logi cal el ements on different cards is broa dl y ill ustrated in the Cisco
MGX 8850 Routing Switch Software Configuration Guide, Release 2.0.
Apart from the way PNNI and th e l ower l evels of logic identify the same ele ment, the sequence of
commands also needs explanatio n. When you configure logical ports—for just one example—you must
complete certain tasks on the AXSM CLI before or after relate d PNNI tasks. For certain command s, this
manual lists prerequisite commands or tasks. For mor e details on the sequence o f tasks, refer to the Cisco
MGX 8850 Routing Switch Softwa r e Co nf igu r ati on Gui de, Release 2.0, for more details of this sequence.
