Understanding SmartPort Macros

SmartPort macros provide a convenient way to save and share common configurations. You can use SmartPort macros to enable features and settings based on the location of a switch in the network and for mass configuration deployments across the network.

Each SmartPort macro is a set of CLI commands that you define. SmartPort macro sets do not contain new CLI commands; Each SmartPort macro is a group of existing CLI commands.

When you apply a SmartPort macro on an interface, the CLI commands contained within the macro are configured on the interface. When the macro is applied to an interface, the existing interface configurations are not lost. The new commands are added to interface and are saved in the running configuration file.

Configuring Smart-Port Macros

You can create a new SmartPort macro or use an existing macro as a template to create a new macro that is specific to your application. After you create the macro, you can apply it to an interface or a range of interfaces.

This section includes information about these topics:

•Default SmartPort Macro Configuration

•SmartPort Macro Configuration Guidelines

•Creating and Applying SmartPort Macros

Default SmartPort Macro Configuration

This section illustrates the default configurations for the four supported macros. These macros can only be viewed and applied; they cannot be modified by the user.

SmartPort Macro Configuration Guidelines

Follow these guidelines when configuring macros on your switch:

•Do not use exit or end commands when creating a macro. This action could cause commands that follow exit or end to execute in a different command mode.

•When creating a macro, all CLI commands should be interface configuration mode commands.

•Some CLI commands are specific to certain interface types. The macro will fail the syntax check or the configuration check, and the switch will return an error message if it is applied to an interface that does not accept the configuration.

•When a macro is applied to an interface, all existing configuration on the interface is retained. This is helpful when applying an incremental configuration to an interface.

•If you modify a macro definition by adding or deleting commands, the changes are not reflected on the interface where the original macro was applied. You need to reapply the updated macro on the interface to apply the new or changed commands.

•You can use the macro trace macro-name interface configuration command to show what macros are running on an interface or to debug the macro to determine any syntax or configuration errors.

•If a command fails when you apply a macro, either due to a syntax error or to a configuration error, the macro continues to apply the remaining commands to the interface.

•Applying a macro to an interface range is the same as applying a macro to a single interface. When you use an interface range, the macro is applied sequentially to each individual interface within the range. If a macro command fails on one interface, it is still applied to the remaining interfaces.

Creating and Applying SmartPort Macros

To create and apply a SmartPort macro, perform the following task:

 
Command
Purpose

Step 1  

Switch # configure terminal

Enters global configuration mode.

Step 2  

Switch(config)# macro name 
macro-name

Creates a macro definition, and enters a macro name. A macro definition can contain up to 3000 characters.

Enters 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.

Do not use the exit or end commands in a macro. This action could cause any commands following exit or end to execute in a different command mode. For best results, all commands in a macro should be interface configuration mode commands.

Step 3  

Switch(config)# interface interface-id

Enters interface configuration mode and specifies the interface on which to apply the macro.

Step 4  

Switch(config-if)# macro {apply | 
trace} macro-name

Applies each command defined in the macro to the interface.

Step 5  

Switch(config-if)# macro description 
text

(Optional) Enters a description about the macro that is applied to the interface.

Step 6  

Switch(config-if)# end

Returns to privileged EXEC mode.

Step 7  

Switch# show parser macro

Verifies that the macro was created.

Step 8  

Switch# show running-config 
interface interface-id

Verifies that the macro is applied to an interface.

Step 9  

Switch# copy running-config 
startup-config

(Optional) Saves your entries in the configuration file.

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. You can delete a macro-applied configuration on an interface by entering the default interface interface-id interface configuration command. Alternatively, you can create an anti-macro for an existing macro that contains the no form of all the corresponding commands in the original macro. Then apply the anti-macro to the interface.

The following sections illustrate how to apply and display the attachments on each of the supported macros:
