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
– fastethernet stack member/module/{first port } - { last port }, where the module is always 0
–
gigabitethernet stack member/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 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 gigabitethernet1/0/1-4 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 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 on switch 1 to 100 Mbps:
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
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 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.
