Using the Interface Command Chapter 9 Configuring the Switch Interfaces Configuring and Using Interface-Range Macros You can create an interface-range macro to automatically select a range of interfaces for configuration. Before you can use the macro keyword in the interface range macro global configuration command string, you must use the define interface-range global configuration command to define the macro. Beginning in privileged EXEC mode, follow these steps to define an interface-range macro: Step 1 Step 2 Command configure terminal define interface-range macro_name interface-range Step 3 interface range macro macro_name Step 4 Step 5 Step 6 end show running-config | include define copy running-config startup-config 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. You do not need to enter spaces before or after the comma. • Each interface-range must consist of the same port type. Select the interface range to be configured by 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. 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: • Valid entries for interface-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 - 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 entering an interface-range. For example, fastethernet 0/1 - 5 is a valid range; fastethernet 0/1-5 is not a valid range. • The VLAN interfaces must 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 as interface-ranges. • All interfaces in a range must be the same type; that is, all Fast Ethernet ports, all Gigabit Ethernet ports, all EtherChannel ports, or all VLANs, but you can combine multiple interface types in a macro.
