Configuring And Using Interface Range Macros - Cisco WS-C3750-48PS-S Software Configuration Manual

Using Interface Configuration Mode

This example shows how to use the interface range global configuration command to set the speed on
ports 1 to 4 on switch 1 to 100 Mbps:
Switch# configure terminal
Switch(config)# interface range tethernet1/0/1 - 4
Switch(config-if-range)# speed 100
This example shows how to use a comma to add different interface type strings to the range to enable
Fast Ethernet ports 1 to 3 on switch 1 and Gigabit Ethernet ports 1 and 2 on switch 2 to receive flow
control pause frames:
Switch# configure terminal
Switch(config)# interface range fastethernet1/0/1 - 3 , gigabitethernet2/0/1 - 2
Switch(config-if-range)# flowcontrol receive on
If you enter multiple configuration commands while you are in interface range mode, each command is
executed as it is entered. The commands are not batched together and executed after you exit interface
range mode. If you exit interface range configuration mode while the commands are being executed,
some commands might not be executed on all interfaces in the range. Wait until the command prompt
reappears before exiting interface range configuration mode.

Configuring and Using Interface Range Macros

You can create an interface range macro to automatically select a range of interfaces for configuration.
Before you can use the macro keyword in the interface range macro global configuration command
string, you must use the define interface-range global configuration command to define the macro.

–
1 to 12
Note When you use the interface range command with port channels, the first and last port
channel number must be active port channels.
You must add a space between the first interface number and the hyphen when using the
interface range command. For example, the command interface range ethernet 1/0/1 - 4 is a valid
range; the command interface range ethernet 1/0/1-4 is not a valid range.
The interface range command only works with VLAN interfaces that have been configured with
the interface vlan command. The show running-config privileged EXEC command displays the
configured VLAN interfaces. VLAN interfaces not displayed by the show running-config
command cannot be used with the interface range command.
All interfaces defined as in a range must be the same type (all Fast Ethernet ports, all Gigabit
Ethernet ports, all EtherChannel ports, or all VLANs), but you can enter multiple ranges in a
command.
