2.6.1 Entering Interface Numbers
In the Global Configuration mode, you can configure a command that only applies to interfaces
specified. For example, you can set up each interface’s VLAN assignment, speeds, or duplex
modes. To configure, you must first enter the interface number. There are four ways to enter your
interface numbers to signify the combination of different interfaces that apply a command or
commands.
Switch(config)# interface 1
Switch(config-if-1)#
Enter a single interface. Only interface 1 will
apply commands entered.
Switch(config)# interface 1,3,5
Switch(config-if-1,3,5)#
Enter three discontinuous interfaces,
separated by commas. Interface 1, 3, 5 will
apply commands entered.
