Chapter 12 Configuring Interface Characteristics
Using Interface Configuration Mode
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 , tengi
gabitethernet1/0/1 - 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:
Use the
no define interface-range macro_name global configuration command to delete a macro.
When using the def
ine interface-range global configuration command, note these guidelines:
• Valid entries for interface-range:
– vlan vlan-ID - vlan-ID, where the VLAN ID is 1 to 4094
– gigabitethernet module/{first port} - {last port} (for Catalyst 3560-E switches), where the
module is always 0
– gigabitethernet stack member/module/{first port} - {last port} (for Catalyst 3750-E switches),
where the module is always 0
– tengigabitethernet module/{first port} - {last port} (for Catalyst 3560-E switches), where the
module is always 0
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.
Step 3
interface range macro macro_name Select the interface range to be configured using the values saved in
the interface-range macro called macro_name.
You can now use the normal configuration commands to apply the
c
onfiguration to all interfaces in the defined macro.
Step 4
end Return to privileged EXEC mode.
Step 5
show running-config | include define Show the defined interface range macro configuration.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
