2 CLI Overview

Rev

The CLI command line interpreter would then parse the command into the

following sequence of instructions:

 Switch to Module command mode.

 Direct subsequent commands to chassis 1 in the current ICIM2 domain.

 Direct subsequent commands to slot 6 of the designated chassis in the current

ICIM2 domain.

 Exit Module mode and return to CLI command mode following command

execution.

 Display the alarm status of the specified device, i.e., the module occupying

chassis 1, slot 6.

 Exit Module mode and return to CLI command mode following command

execution.

This command entry format is generally preferred for use by element management

systems. For maximum efficiency, these systems should be programmed to send CLI

commands in non-modal format, i.e., with all command parameters on a single line.

On occasion, this method may also be more efficient than modal entry for craft

operators who are already very familiar with the syntax of the command being used.

Command Usage Guidelines

 CLI commands, unlike login passwords, are insensitive to case. For example, the

keywords Set, set, and SET all have the same meaning in CLI.

 If a particular action requires parameters that are not included in the command,

an error message will be issued.

 In general, CLI commands issued from an element management system should

have the non-modal "single-line" form shown above. Exceptions may be made

where they will improve efficiency.

 For non-modal command entry, the exit parameter is included for backward

compatibility. It is not required in order to return to the CLI mode.

 Mode changes can be used to restrict the scope of most CLI commands. When

the command mode changes, the prompt changes to reflect the new mode.

Wildcards

Some CLI command parameters can include one or more "wildcard" characters (*)

for added flexibility.

The following sample dialog shows how a craft operator could use a wildcard to

check the output power on all modules in chassis 20:

CLI> module

1 2 ... 35 36 37 38 39 40 41 42 43 44 45 ... 307 308
