e the command macro description, followed by the name of the macro: interface GigabitEthernet1/0/20 description < Server ]> switchport mode access macro description SetServerPorts storm-control broadcast level bps 1g 900m spanning-tree portfast You can add your own macro description with the macro description command, from within the macro, or from the command line: 3750(config-if)#macro description [ - Macro Description - ] interface GigabitEthernet1/0/20 description <[ Server ] switchport mode access macro description SetServerPorts [ - Macro Description -] storm-control broadcast level bps 1g 900m spanning-tree portfast As you can see, every time you run a macro or execute the macro description command, the description specified (or the macro name) is appended to the macro description command in the configuration of the interface to which it's applied. Iterations are sep- arated with vertical bars. Chapter 19: Catalyst 3750 Features An easier way to see where macros have been applied is with the show parser macro description command. Here, you can see that I ran the same macro repeatedly on the Gil/0/20 interface: SW2#sho parser macro description Interface Macro Description(s) Gi1/0/20 SetServerPorts SetServerPorts SetServerPorts [ Macro Description ] To see all the macros on the switch, use the show parser macro brief command: 3750#sho parser macro brief default global : cisco-global default interface: cisco-desktop default interface: cisco-phone default interface: cisco-switch default interface: cisco-router default interface: cisco-wireless customizable : SetServerPorts Six macros are included in IOS by default, as you can see in the preceding output (the six listed default macros). You can use the show parser macro name macroname to view the details of any of the macros: SW2#sho parser macro name cisco-desktop Macro name : cisco-desktop Macro type : default interface # macro keywords $access vlan # Basic interface - Enable data VLAN only # Recommended value for access vlan should not be 1 switchport access
