Chapter5 PNNI Commands Position-Dependent and Keyword-Driven Parameters
Position-Dependent and Keyword-Driven Parameters
A command can include param ete rs that are keyword-driven or position-dependent.
For position-dependent parameters, you must type parameters in the order they appear in the syntax
description or on-line help. To create a logical port, for example, the pos it io n-d ep en de nt s y nt ax is:
addport <ifNum> <bay.line> <guaranteedRate> <maxrate> <sctID> <ifType> [vpi]
For a keyword-driven parameter, a keyword must precede the value. The keyword is preceded by a dash
and followed by the parameter (–timeou t <secs>, for example). The order you enter keyword-driven
parameters does not matter—although any preceding or succeeding, positi on-dependent param e t er s
must appear as they do in the com m an d syn ta x de sc rip ti on .
In the following syntax example, th e co mm and is to delete more than one c on n ect io n at a t im e . Th e
mandatory, position-dependent connection identifier consist of a logical port (ifNum) and the VPI and
VCI of the first connection t o de let e . A ft er th e co nn ec tion identifier, the line shows two o ptional,
keyword-driven parameters. These keyword-driven parameters let you enter the number of connections
to delete and specify verb os e m o d e :
delcons <ifNum> <vpi> <vci> [-num <num.conns to del>] [-verbose < 1 | 0 >]
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 parameter s ) , a message displays t he syntax and paramet e r r a n ge s. The returned me s sa g e m ay
also suggest what the problem i s. For example, the message may w ar n of t oo f ew p ar ame ters. No error
messages or warnings appear u nt il yo u co mp le te the command.
Identifying the AXSM Models
The model number of an AXSM identifies the line s peed, line count, and number of bays (see Ta ble 5- 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 use 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 the
Cisco MGX 8850 Routing Switch Hardware Installation Guide, Rel 2.0.
