Chapter11 Configuring Smartports Macros

Configuring Smartports Macros

The Cisco-default macros use the $ character to help identify required keywords. There is no

restriction on using the $ character to define keywords when you create a macro.

Creating Smartports Macros

Beginning in privileged EXEC mode, follow these steps to create a Smartports macro:

The no form of the macro name global configuration command only deletes the macro definition. It

does not affect the configuration of those interfaces on which the macro is already applied.

This example shows how to create a macro that defines the switchport access VLAN and the number of

secure MAC addresses and also includes two help string keywords by using # macro keywords:

Switch(config)# macro name test

switchport access vlan $VLANID

switchport port-security maximum $MAX

#macro keywords $VLANID $MAX

@

Command Purpose

Step1 configure terminal Enter global configuration mode.

Step2 macro name macro-name Create a macro definition, and enter a macro name. A macro definition

can contain up to 3000 characters.

Enter the macro commands with one command per line. Use the @

character to end the macro. Use the # character at the beginning of a line

to enter comment text within the macro.

(Optional) You can define keywords within a macro by using a help

string to specify the keywords. Enter #macro keywords word to define

the keywords that are available for use with the macro. Separated by a

space, you can enter up to three help string keywords in a mac ro.

Macro names are case sensitive. For example, the commands macro

name Sample-Macro and macro name sample-macro will result in

two separate macros.

We recommend that you do not use the exit or end commands or change

the command mode by using interface interface-id in a macro. This

could cause any commands following exit, end, or interface

interface-id to execute in a different command mode. For best results,

all commands in a macro should be in the same configuration mode.

Step3 end Return to privileged EXEC mode.

Step4 show parser macro name macro-name Verify that the macro was created.
