Cisco Systems Cisco IOS XR manual Configuring the SDR Hostname, Aborting a Configuration Session

Chapter 4 Configuring General Router Features

Configuring the SDR Hostname

If you end a configuration session without committing the configuration changes, the router prompts you to save changes, discard changes, or cancel the action, as shown in the following example:

RP/0/RP0/CPU0:router(config-if)# end

Uncommitted changes found, commit them before exiting(yes/no/cancel)? [cancel]:

Respond to the prompt by entering one of the following options:

•yes, commit the configuration changes and exit configuration mode

•no, exit configuration mode without committing the configuration changes

•cancel, remain in configuration mode without committing the configuration changes

Note In EXEC mode, the exit command logs the user out of the system.

Aborting a Configuration Session

When you abort a configuration session, any changes are discarded and the configuration session ends. No warning is given before the configuration changes are deleted.

In global configuration mode, the abort command discards configuration changes and returns to EXEC mode. In administration configuration mode, the abort command discards configuration changes and returns to administration EXEC mode. To abort a configuration session, enter the abort command, as shown in the following example:

RP/0/RP0/CPU0:router# configure

RP/0/RP0/CPU0:router(config)# hostname host1

RP/0/RP0/CPU0:router(config)# interface POS 0/2/0/2

RP/0/RP0/CPU0:router(config-if)# description this is my interface

RP/0/RP0/CPU0:router(config-if)# ipv4 address 10.1.1.1 255.0.0.0

RP/0/RP0/CPU0:router(config-if)# shutdown

RP/0/RP0/CPU0:router(config-if)# abort

RP/0/RP0/CPU0:router#

Configuring the SDR Hostname

The hostname identifies an SDR on the network. Although devices can be uniquely identified by their Layer 2 and Layer 3 addresses (such as an IP address), it is often simpler to remember network devices by an alphanumeric “hostname.” This name is used in the CLI prompt and default configuration filenames and to identify the SDR on the network.

To configure the hostname, enter the hostname command with the SDR name as shown in the following example:

RP/0/RP0/CPU0:router# configure

RP/0/RP0/CPU0:router(config)# hostname SDR_SJ

RP/0/RP0/CPU0:router(config)# commit

RP/0/RP0/CPU0:Apr 7 00:07:33.246 : config[65669]: %LIBTARCFG-6-COMMIT : Configu

ration committed by user 'user_a'. Use 'show configuration commit changes 1000000067' to view the changes.

RP/0/RP0/CPU0:SDR_SJ(config)#

The preceding example sets the SDR name to SDR_SJ.
