Chapter 11 Configuring Interface Characteristics
Beginning in privileged EXEC mode, follow these steps to define an interface range macro:
Command
Step 1 configure terminal
Step 2 define interface-range macro_name
interface-range
Step 3 interface range macro macro_name
Step 4 end
Step 5
show running-config | include define
Step 6 copy running-config startup-config
Use the no define interface-range macro_name global configuration command to delete a macro.
When using the define interface-range global configuration command, note these guidelines:
•
•
•
•
78-16180-02
Valid entries for interface-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 12.
When you use the interface ranges with port channels, the first and last port channel
Note
number must be active port channels.
You must add a space between the first interface number and the hyphen when entering an
interface-range. For example, ethernet 1/0/1 - 4 is a valid range; ethernet 1/0/1-4 is not a valid
range.
The VLAN interfaces must 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 as interface-ranges.
All interfaces defined as 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 combine multiple interface types
in a macro.
Purpose
Enter global configuration mode.
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.
•
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
configuration to all interfaces in the defined macro.
Return to privileged EXEC mode.
Show the defined interface range macro configuration.
(Optional) Save your entries in the configuration file.
