Chapter10 Configuring Interface Characteristics
Using Interface Configuration Mode
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 ra nge 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
to100 Mb/s on ports 1 to 4 on switch 1:
Switch# configure terminal
Switch(config)# interface range gigabitethernet1/0/19 - 20
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 i n inter face-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 comm a nd to d efine th e m a cro.
Beginning in privileged EXEC mode, follow these steps to define an interface range macro:
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 define interface-range macro_name
interface-range Define the interface-range macro, and save it in NVRAM.
•The macro_name is a 32-character maximum character string.
•A macro can contain up to five comma-separated interfa ce ranges.
•Each interface-range must consist of the same port type.
