Cisco IOS - DNS lookup

Updated:   |  Cisco IOS articles

Follow these directions to assign a hostname to a Cisco switch in IOS.

  1. In IOS, type enable and press enter
  2. Type configure terminal and press enter
  3. Type no ip domain-lookup and press enter
  4. Type exit and press enter

The reload command can be used to return the switch to the configuration it had before any changes were made.

To ensure these changes remain saved if the switch is restarted, save the changes to the startup-config. Type copy running-config startup-config and press enter. This saves to NVRAM. To ensure the startup-config contains the new hostname, use the show startup-config command. It is also possible to save the changes to flash using the copy startup-config flash command. Then use the show flash command, and the startup-config file should be listed.
