Viewing Existing Smartport Macros

Smartport comes with a small number of default macros which can be applied to your Cisco network devices. To examine your existing Smartport macros, you use the ever-popular show command — specifically, you use show parser macro. This shows you how many macros are on the switch and exactly what commands are in those macros. Some of these macros are easy to execute, whereas others may require parameters to operate correctly.

Viewing macros using the brief option

The first version of this command includes the brief option, which lists the macros found on the system and illustrates the types of devices for which a macro can apply, in either Global Configuration mode or Interface Configuration mode.

Switch1> enable
Switch1# configure terminal 
Switch1#show 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

Viewing macros without the brief option

If you do not use the brief option, you see the following output related to all the macros found on your system. The output of the command includes a count of the macros, as well as full details about each macro, from its name to all the commands that make up the macro. This code sample is the output of the default macros found on an IOS 12.x Catalyst 2960 switch:

Switch1> enable
Switch1# configure terminal 
Switch1# show parser macro
Total number of macros = 6

That was a lot of data! Now imagine having to type in each set of configuration commands every time you wanted to configure a switch interface for another job role! Macros can save your limbs from unwanted carpal tunnel syndrome.
