# Append lines including "snmp" in the running configuration to the file test.txt.

<Sysname> display current-configuration | include snmp >> test.txt

Saving the running configuration

To make your configuration take effect after a reboot, save the running configuration to a configuration

file by using the save command in any view. This command saves all commands that have been

successfully executed except for the one-time commands. Typical one-time commands include the display

commands used for displaying information and the reset commands used for clearing information.

For more information about the save command, see Fundamentals Command Reference.
