How to Configure Multiple Cisco Switch Ports at the Same Time

Using the interface range command will save you time when configuring multiple ports with the same characteristics.


To configure multiple switchports at the same time, we use the interface range configuration command.

Example:
Switch(config)#interface range fastethernet0/1 – 20
Switch(config-if-range)#speed 100
Switch(config-if-range)#duplex full

The previous example will hardcode the speed and duplex settings on switchports 1 to 20. However, this could well have been assigning them all to the same vlan.

We can even define multiple ranges.

Example:
Switch(config)#interface range fastethernet0/1 – 4 , fastethernet0/10 – 15

Notice the spaces between the ranges.

The interface range command works with vlan, port-channel, fastethernet and gigabitethernet interfaces.

    is there any option avail for non-sequential ports like fa 0/1 fa 3/40 need to be changed to a same VLAN in single command

    • JWilliams

      Just use the same command as for multple ranges but only define to siungle ports.

      We can even define multiple ranges.
      Example
      Switch(config)#interface range fastethernet0/1, fastethernet0/10

    For multiple non-contiguous ports I believe space is needed before and after comma

    e.g.:
    Switch(config)#interface range fa0/1 , fa0/10
