Command Line Interface Overview
This chapter describes the com mand line interface (CLI) for the Cisco MGX 8850 node. In addition, the
chapter describes the basic user-commands for logging on to and out of the switch, changing between
the CLI of different cards, and list ing files on the hard drive. This chapte r includes usage examples. For
information on how to configure a switch and basic network services, refer to the Cisco MGX 8850
Routing Switch Software Configuration Guide, Release 2.0..
The chapter describes:
•The role of the CLI on the switch
•The information contained in the CLI prompt
•The command syntax
•Contents of a comma nd d e sc ription
•Identification of the models o f th e ATM Switching Service Module (AXSM )
•A logical port in the context of the Public Network-to-Network (PNNI) protocol
•A logical port in the context of AXSM configuration
•User-specific commands
The Role of the CLI
During normal operation, the tools for configuring, monitoring, and controlling a switch are the
CiscoView application for equipment management and the Cisco WAN Manager application for
connection management. However, during initial switch installation, troubleshooting, or where
low-level control is important, the comm and line interface (CLI) provides the be st a ccess to the switch.
Each PXM45 and service module supports its own CLI. Each card has a set of commands specific to its
card-type—although some comm an ds overlap . I n ce rt ai n i n stan ce s , t hi s m an u al in di ca tes case s where
two commands with the same name produce different results on different card types. (The available
command set also depe nds on the privilege level o f th e user.)
Although you can execute a command on only the card that supports that command, the target of the
command can be another card when you are “on” the PXM4 5. (Be ing “on” a ca rd m ean s yo u ha v e logg ed
into the card and are using the CLI for that card.) On the PXM45, you can execute commands that target
the PXM45 itself, the whole n o de , o r a s e rv ic e m odule.
To move from the CLI of one card to the CLI of another card, use the Change Card (cc) command. The
description of cc appears in this chapter.
