Chapter 12 Configuring Interface Characteristics
Using Interface Configuration Mode
When using the interface range global configuration command, note these guidelines:
• Valid entries for port-range, depending on port types on the switch:
–
vlan vlan-ID, where the VLAN ID is 1 to 4094
Note Although the command-line interface shows options to set multiple VLANs, these
options are not supported on Catalyst 2960 and 2960-S switches.
–
, where the module is always 0
–
fastethernet module/{first port} - {last port}, where the module is always 0
–
gigabitethernet 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 6
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, interface range gigabitethernet 0/1 - 4 is a valid range; interface range
gigabitethernet0/1-4 is not.
• 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 ra nge command.
• All interfaces defined 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 enter multiple ranges in a command.
This example shows how to use the interface range global configuration command to set the speed on
ports 1 to 2 to 100 Mb/s:
Switch# configure terminal
Switch(config)# interface range gigabitethernet0/1 - 2
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
Fast Ethernet ports 1 to 3 and Gigabit Ethernet ports 1 and 2 to receive flow-control pause frames:
Switch# configure terminal
Switch(config)# interface range fastethernet0/1 - 3, gigabitethernet0/1 - 2
Switch(config-if-range)# flowcontrol receive on
Step 5 show interfaces [interface-id] Verify the configuration of the interfaces in the range.
Step 6 copy running-config startup-config (Optional) Save your entries in the configuration file.
