Using the Interface Command Chapter 11 Configuring Interface Characteristics Beginning in privileged EXEC mode, follow these steps to configure a range of interfaces with the same parameters: Step 1 Step 2 Command configure terminal interface range {port-range | macro macro_name} Step 3 Step 4 Step 5 Step 6 end show interfaces [interface-id] copy running-config startup-config 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 "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. 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. 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 port}, 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 range 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 11-6 Catalyst 2950 and Catalyst 2955 Switch Software Configuration Guide 78-11380-10
