Chapter11 Configuring Interface Characteristics
Using the Interface Command
Beginning in p r ivileged EXEC mode, follow these steps to configure a range of interfaces with the
sameparameters:
When using the interface range global configuration command, note these guidelines:
•Valid entries for port-range:
–
vlan vlan-ID - vlan-ID, where VLAN ID is from 1 to 1005 with the SI installed or 1 to 4094
with the EI installed
–
fastethernet slot/{first port} - {last port}, where slot is 0
–
gigabitethernet slot/{first port} - {last po rt}, where slot is 0
–
longreachethernet slot/{first port} - {last port}, where slot is 0
–
port-channel port-channel-number - port-channel-number, where port-channel-number is
from 1 to 6
•You must add a space between the interface numbers and the hyphen when using the
interface range command. For example, the command interface range fastethernet 0/1 - 5 is a
valid range; the command interface range fastethernet 0/1-5 is not a valid range.
•The interface range command works only with VLAN interfaces that have been configured with
the interface vlan command (the show running-config privileged EXEC command output shows
the configured VLAN interfaces). VLAN interfaces that do not appear by using the show
running-config command cannot be used with the interface ran ge command.
•All interfaces in a range must be the same type; that is, all Fast Ethernet ports, all Gigabit Ethernet
ports, all EtherChannel ports, or VLAN interfaces.
This example shows how to use the interface range global configuration command to set the speed on
Fast Ethernet interfaces 0/1 to 0/5 to 100 Mbps:
Switch# configure terminal
Switch(config)# interface range fastethernet0/1 - 5
Switch(config-if-range)# speed 100
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 interface range {port-range | macro
macro_name} 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 “Configuring and Using
Interface-Range Macros” section on page 11-7.
•Each comma-separated port-range must consist of the same port
type. You do not need to enter spaces before or after the comma.
•When you define a range, the space between the first port and the
hyphen is required.
Step3 You can now use the normal configuration commands to apply the
configuration parameters to all interfaces in the range.
Step4 end Return to privileged EXEC mode.
Step5 show interfaces [interface-id] Verify the configuration of the interfaces in the range.
Step6 copy running-config startup-config (Optional) Save your entries in the configuration file.
