Troubleshooting Commands
This chapter describes commands that directly or indirectly facilitate troubleshooting. They include
commands for viewing and clearin g ala rms and statistics. The chapter b egi ns wi th a de s cr ipti on o f th e
CLI, various elements of the A XSM , and the PNNI port identifier.
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 po sit io n-d ep en de nt syntax is:
addport <ifNum> <bay.line> <guaranteedRate> <maxrate> <sctID> <ifType> [vpi]
For a keyword-driven parameter, a keyword must precede the value. The keywo r d 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 - de pendent parameters
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 ime. The
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 pt io na l,
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 er ranges. The retu rn ed message may
also suggest what the problem i s. For example, the message may w ar n of t oo few parameters. No error
messages or warnings appear u nt il yo u co mp le te the command.
