Chapter1 Command Line Interface Overview
Identifying the AXSM Models
•The syntax of the command. This manual presents parameters in a co lu m n t o make th em easier to
read, particularly when displayed through an electronic medium.
•A syntax description lists al l t he parameters. Each item in the list includes a brief definiti on,
functional details when appropria te, the ra nge of v alu es fo r th e para mete r , and a n appli cab le de faul t
value.
Note that, in many instance s, th e def ault v alu e is no t merel y a basic star tin g value but rathe r the m ost
desirable or commonly used value.
•Occasionally, the description includes a Usage Guidelines section when the complexity of the
command warrants it. The Usag e G u id el ines section contains importan t de tai ls ab ou t usi ng the
command. When needed , an additional section with a specialized f o cus may appear. An example is
the Version Numbe ring description for the fi rm ware upgrade commands (see loadrev, for example).
•An Attributes section li s ts t he following details:
•Whether the switch logs each in s ta nc e o f co mm an d execu ti o n. Typically, the swit ch logs each
configuration change but no display commands.
•The state of the card required to a execu te a command. The state can be active, stand by, initializ ed
(infrequently), or any of these states.
•A Related Commands lists other commands in the typical grouping of commands (add, delete,
configure, and display) or other commands that could complement the command.
•An Example section shows one or mo re exa mpl es o f co m ma nd u sag e. The text for this section
describes the intention of the command and may also describe an outcome. A representation of
screen output usually appears. Occasional ly, supplemental commands and screen samples appear in
support of the example.
Identifying the AXSM Models
The model number of an AXSM identifies the line s peed, line count, and number of bays (see Ta ble 1- 1.)
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 se cond in b ay 2 (lo wer slo t). 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.
