This document outlines the procedure to change the Network Interface
Card (NIC) settings on a Cisco CallManager 5.x server via the Command Line
In Cisco CallManager 5.x, you can use the CLI in order to perform basic
operating system functions. The CLI can be accessed from the console or through
a secure shell connection to the server and provides a subset of the operating
system functionality that is available through the operating system user
interface. The CLI is designed for system emergencies and not as a replacement
for the user interface.
Ensure that you have the prerequisites to start a CLI session as
Unified Communications Operating System Administration Guide, Release 5.0,
Command Line Interface.
The information in this document is based on Cisco CallManager 5.x.
The information in this document was created from the devices in a
