Cisco

How many times do you type show ip interface brief, copy run start, configure terminal, show running-config, etc. But isn’t there a way to make thing easier? Yes there is, that’s command aliases facility provided with the Cisco IOS.

You might have experienced that while you are typing a command on a terminal, some stuff get thrown to the terminal be the router or the switch making it a mess. This stuff can be useful specially when you are configuring a routing protocol or changing setting on an interface. However mssages like the following, is quite disturbing when you are doing some task.

In privilege EXEC mode, when you type in something other than a Cisco command, the router assumes that you are typing a domain name and it tries to resolve what ever you type.

Although this feature is can be useful in some situations, for most of the time, this is a pain. The router becomes irresponsive for about 5-6 seconds trying to resolve the name.
