Command Entry

Command Entry
When you enter a command with the current version of the product, you must type all intended
arguments before you press the Return key or Enter key.
If you press the Return key or Enter key with incorrect parameters or no parameters (if the command
requires parameters), a message displays the syntax and parameter ranges. The returned message may
also suggest what the problem is. For example, the message may warn of too few parameters. No error
messages or warnings appear until you complete the command.

Identifying the AXSM Models

The model number of an AXSM identifies the line speed, line count, and number of bays (see
Note that the number of lines applies to an individual back card, so the total number of lines supported
by the front card equals the highest line number times the number of bays. The OC-48 card
AXSM-1-2488 has the lowest number of lines—one. The highest number of lines exist on the
AXSM-16-155 and AXSM-16-T3E3—16, as the name indicates.
The MGX 8850 node uses the concept of a bay. The bay refers to the upper or lower location of a
single-height card. (The switch has a double-height card cage, so a single-height back card necessarily
occupies either an upper or lower position.)
The T3/E3, OC-3, and OC-12 versions of the AXSM can have two back cards, one in bay 1 (upper
location of the back slot) and the second in bay 2 (lower slot). The MGX-AXSM-1-2488 (OC-48 AXSM)
can have a back card in bay 1 only. For further descriptions and illustrations of the card sets, refer to
Cisco MGX 8850 Hardware Installation, Release 2.

Connection Capacities of the AXSM

The SVC and SPVC connection capacities for the front card, back card, and physical lines appear in
Table 7-2
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.
