Today we will look for setting Cisco devices host name and then disable domain look up. Host name is used to identify devices in a meaningful and easy way.

Change Hostname

First we change hostname to ismailbaydan.com and then fall back to default hostname which is Switch

Enable Domain Lookup

First we enable domain look up which is enabled by default and then disable domain look up

We can check current status of domain look up by filtering running config where filter is “domain”. As you can see domain look up is disabled. Then we flip to default value and then filter again the running config so there is no line about domain look up which means it is enabled by default as we said before.

Print Hostname Configuration
