 You can set the IP address of any [interface](#interfaceline-configuration-mode), by entering `ip address [ip-address] [subnet mask]`. On a switch this is usually done on a certain VLAN, on a router this can be done in the `loopback [number]` interface. The default gateway is given by `ip default-gateway [ip-address]`.

+
+### User EXEC Mode
 
 After you access the device, you are automatically in user EXEC command mode. The EXEC commands available at the user level are a subset of those available at the privileged level. This is the least privileged command mode. User EXEC mode is denoted by a `>`.

+### Privileged EXEC Mode
 
 The privileged command set includes those commands contained in user EXEC mode as well as commands that configure operating parameters. Privileged access should be password-protected to prevent unauthorised use, you can achieve this by entering the `enable secret [password]` command in [global configuration mode](#global-configuration-mode). It is highly recommend to also enable [password encryption](#password-encryption). Privileged EXEC mode is denoted by a `#`.
 
 To access privileged EXEC mode, enter the `enable` command from user EXEC mode.

+### Global Configuration Mode
 
 Configuration mode commands apply to features that affect the device as a whole. Global configuration mode is denoted by `(config)#`.
 
 From privileged EXEC mode you can reach global configuration mode by entering the `configure terminal` command.
 
 To execute a command that's usually only available from privileged EXEC or User EXEC mode, like `show ip interface brief`, you have to preced it by `do`. [^1]

+### Interface/Line Configuration Mode
 
 Interface/Line configuration mode commands let you configure specific interfaces/lines on the router. Interface configuration mode is denoted by `(config-if)#` and line configuration mode by `(config-line)#`.
 
 From global configuration mode you can reach interface configuration mode by entering the `interface [interface-name]` command. Similarly to reach line configuration mode you can enter the `line [line-name]` command.
 
 You can go back to the privileged EXEC mode from this mode by entering the command `end`.

 In some cases you want your device to be secure from overloading. For example you bandwidth, you want to make sure that the connections on your port has some bandwidth. Because if you have 100 devices on one port, the bandwidth has to be shared. With only 1 device on your port you have the whole bandwidth for that device. Another reason would be the Availability of the port, because if 100 devices have to communicate through 1 port, you'll have a huge que of actions your port has to finish.
