SPVC and SVC Commands
This chapter describes the commands that apply to semi-permanent virtual circuits (SPVCs) and
switched virtual circuits (SVCs). These commands allow you to add, delete, configure, display status,
and specify statistics for thes e c on n ect io ns. Th e c ommands include the following ar eas:
•Adding a connection
•Modifying an existing con ne ction
•Deleting a connection
•Display one connection or a ll connections
•Downing and upping a connection in the course of maintenance or troubleshooting
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 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 para me t e r 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 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 >]
