Chapter 11 Configuring Interface Characteristics

Using Interface Configuration Mode

When using the interface range global configuration command, note these guidelines:

•Valid entries for port-range:

–vlan vlan-ID- vlan-ID, where the VLAN ID is 1 to 4094

–gigabitethernet module/{first port} - {last port}, where the module is always 0 (for Catalyst 3560-E switches)

gigabitethernet stack member/module/{first port} - {last port}, where the module is always 0 (for Catalyst 3750-E switches)

–tengigabitethernet module/{first port} - {last port}, where the module is always 0 (for Catalyst 3560-E switches)

tengigabitethernet stack member/module/{first port} - {last port}, where the module is always 0 (for Catalyst 3750-E switches)

–port-channelport-channel-number - port-channel-number, where the port-channel-number is 1 to 48

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 gigabitethernet1/0/1 - 4 is a valid range; the command interface range gigabitethernet1/0/1-4is 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-configprivileged EXEC command displays the configured VLAN interfaces. VLAN interfaces not displayed by the show running-configcommand cannot be used with the interface range command.

•All interfaces defined in a range must be the same type (all Gigabit Ethernet ports, all 10-Gigabit Ethernet ports, all EtherChannel ports, or all VLANs), but you can enter multiple ranges in a command.

This example shows how to use the interface range global configuration command to set the speed to 100 Mb/s on ports 1 to 4 on switch 1:

Switch# configure terminal

Switch(config)# interface range gigabitethernet1/0/1 - 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 Gigabit Ethernet ports 1 to 3 and 10-Gigabit Ethernet ports 1 and 2 to receive flow-control pause frames:

Switch# configure terminal

Switch(config)# interface range gigabitethernet1/0/1 - 3 , tengigabitethernet1/0/1 - 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 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.
