Configuring Interface Characteristics
You can also configure a range of interfaces by using the interface range or interface range macro
global configuration commands. Interfaces configured in a range must be the same type and must be
configured with the same feature options.
After you configure an interface, verify its status by using the show privileged EXEC commands listed
Step 4
in the
Enter the show interfaces privileged EXEC command to see a list of all interfaces on or configured for
the switch. A report is provided for each interface that the device supports or for the specified interface.
Configuring a Range of Interfaces
You can use the interface range global configuration command to configure multiple interfaces with the
same configuration parameters. When you enter the interface range configuration mode, all command
parameters that you enter are attributed to all interfaces within that range until you exit this mode.
Beginning in privileged EXEC mode, follow these steps to configure a range of interfaces with the
same parameters:
Command
Step 1
configure terminal
Step 2
interface range {port-range | macro
macro_name}
Step 3
Step 4
end
Step 5
show interfaces [interface-id]
Step 6
copy running-config startup-config
When using the interface range global configuration command, note these guidelines:
•
78-16180-02
"Monitoring and Maintaining the Interfaces" section on page
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
–
Purpose
Enter global configuration mode.
Enter interface range configuration mode by entering the range of
interfaces (VLANs or physical ports) to be configured.
•
You can use the interface range command to configure up to five
port ranges or a previously defined macro.
The macro variable is explained in the
•
Interface Range Macros" section on page
In a comma-separated port-range, you must enter the interface
•
type for each entry and enter spaces before and after the comma.
•
In a hyphen-separated port-range, you do not need to re-enter the
interface type, but you must enter a space before the hyphen.
You can now use the normal configuration commands to apply the
configuration parameters to all interfaces in the range.
Return to privileged EXEC mode.
Verify the configuration of the interfaces in the range.
(Optional) Save your entries in the configuration file.
