Chapter10 Configuring Interface Char acteristics
Using Interface Configuration Mode
When using the interface range global configuration command, note these guidelines:
•Valid entries for port-range:
–
vlan vlan-ID, where the VLAN ID is 1 to 4094
Note Although the command-line interface (CLI) shows options to set multiple VLANs, these
options are not supported.
–
fastethernet module/{first port} - {last port}, where the module is always 0
–
gigabitethernet module/{first port} - { last port}, where the module is always 0
–
port-channel port-channel-number - port-channel-number, where the port-channel-number
is 1 to 6
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 interf ace range gigabitethernet0/1 - 4 is a
valid range; the command interface range gigabitethernet0/1-4 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 ra nge command.
•All interfaces defined 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.
This example shows how to use the interface range global configuration command to set the speed on
ports 1 to 4 to 100 Mbps:
Switch# configure terminal
Switch(config)# interface range gigabitethernet0/1 - 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 and Gigabit Ethernet ports 1 and 2 to receive flow-control pause frames:
Switch# configure terminal
Switch(config)# interface range fastethernet0/1 - 3 , gigabitethernet0/1 - 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
re-appears 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 comm and to define the macro.
