Chapter 11 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 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 gigabitethernet1/0/19 - 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 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.
Beginning in privileged EXEC mode, follow these steps to define an interface range macro:
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
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 interface
ranges.
•
Each
interface-range
must consist of the same port type.
