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.

There are Cisco-default SmartPorts macros embedded in the switch software (see Table 17-1). You can display these macros and the commands they contain by using the show parser macro user EXEC command.

Cisco also provides a collection of pretested, Cisco-recommended baseline configuration templates for Catalyst switches. The online reference guide templates provide the CLI commands that you can use to create SmartPorts macros based on the usage of the port. You can use the configuration templates to create SmartPorts macros to build and deploy Cisco-recommended network designs and configurations.

Configuring SmartPort 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:

•Passing Parameters Through the Macro

•Default SmartPort Macro Configuration

•SmartPort Macro Configuration Guidelines

•Creating SmartPorts Macros

•Applying SmartPorts Macros

Passing Parameters Through the Macro

Some commands might not be sufficiently generic for all the interfaces; for example, VLAN ID for Layer 2 interfaces and the IP address for Layer 3 interface. Retaining such commands in macro definitions requires that you change the value of such parameters (like VLAN ID or IP address) before applying the macro to different interfaces. Alternatively, it requires that you create different macros for each possible value of its parameters.

The macro infrastructure can be enhanced to support accepting parameters while applying a macro. The parameters are passed as keyword-value pairs.

The CLI limits the number of keyword-value pairs to a maximum of three, where the first parameter must be the keyword, the second is its corresponding value, and the third parameter would be the keyword for the second keyword-value pair. Here is an example of how to pass parameters to a command-macro:

Switch(config)# macro name parameter-test

Enter macro commands one per line. End with the character '@'.

switchport mode access

switchport access vlan $VLANID

switchport port-security

switchport port-security maximum $MAXHOST

If the above macro is applied to some interface without parameters, the invalid commands fail. Instead, you should apply the macro with appropriate keyword-value pair parameters, as follows:

Switch(config-if)# macro apply parameter-test $VLANID 1 $MAXHOST 5

The above command applies the macro after replacing $VLANID with 1 and $MAXHOST with 5. Be aware that you can specify any string in the macro as a keyword.

Macro Parameter Help

It is often difficult to remember the macro keywords while applying a macro to an interface or switch. Macros can contain the definitions for mandatory keywords. If you apply a macro without those keyword values, the commands are considered invalid and they will fail.

You can enhance the macro infrastructure to provide help on keywords defined in macros. While creating a macro, you can specify a help string (as a comment) to list the mandatory keywords for that macro.

The following example illustrates how to specify the help string for the keywords:

Switch(config)# macro name test

switchport access vlan $VLANID

switchport port-security maximum $MAX

#macro keywords $VLANID $MAX

Help string can be anywhere in the macro. The following example illustrates an alternate way to specify the help string:

Switch(config)# macro name test

switchport access vlan $VLANID

#macro keywords $VLANID

switchport port-security maximum $MAX

#macro keywords $MAX

SmartPort Macro Configuration Guidelines

Follow these guidelines when configuring macros on your switch:

•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.

•cisco-global needs to be applied at the global configuration mode. Cisco recommends that you apply this macro before any other interface level macro.

•Specific keywords are required when you apply the system-defined macros (cisco-desktop, cisco-phone, cisco-switch, and cisco-router) on an interface.

•When using the cisco-phone macro to apply port security, the port security maximum is 2 (switchport port-security maximum 2).

•At most, 3 keyword-value pairs are allowed per system-defined macro.

•When creating a macro, do not use the exit or end commands or change the command mode by using interface interface-id. This could cause commands that follow exit, end, or interface interface-id to execute in a different command mode.

•When creating a macro, ensure that all CLI commands are in the same configuration mode.

•When creating a macro that requires the assignment of unique values, use the parameter value keywords to designate values specific to the interface. Keyword matching is case sensitive. All matching occurrences of the keyword are replaced with the corresponding value. Any full match of a keyword, even if it is part of a larger string, is considered a match and is replaced by the corresponding value.

•Macro names are case sensitive. For example, the commands macro name Sample-Macro and macro name sample-macro result in two separate macros.

•Some macros might contain keywords that require a parameter value. You can use the macro global apply macro-name ? global configuration command or the macro apply macro-name ? interface configuration command to display a list of any required values in the macro. If you apply a macro without entering the keyword values, the commands are invalid and are not applied.

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

•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 global trace macro-name global configuration command or the macro trace macro-name interface configuration command to apply and debug a macro to find any syntax or configuration errors. If a command fails because of a syntax error or a configuration error, the macro continues to apply the remaining commands.

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

•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 interface within the range. If a macro command fails on one interface, it is still applied to the remaining interfaces.

•When you apply a macro to a switch or a switch interface, the macro name is automatically added to the macro description of the switch or interface. You can display the applied commands and macro names by using the show parser macro description user EXEC command.

•The user-configurable macro has a buffer that can take commands and comments up to 3000 characters. Each newline would take 2 characters and empty lines are counted as is.

There are Cisco-default SmartPorts macros embedded in the switch software (see Table 17-1). You can display these macros and the commands they contain by using the show parser macro user EXEC command.

Follow these guidelines when you apply a Cisco-default SmartPorts macro on an interface:

•Display all macros on the switch by using the show parser macro user EXEC command. Display the contents of a specific macro by using the show parser macro macro-name user EXEC command.

•Keywords that begin with $ mean that a unique parameter value is required. Append the Cisco-default macro with the required values by using the parameter value keywords.

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

To create a SmartPorts macro, perform this task:

Switch# configure terminal

Switch(config)# macro name 
macro-name

Switch(config)# end 

Switch# show parser macro name 
macro-name

Applying SmartPorts Macros

To apply a SmartPorts macro, follow these steps:

Switch# configure terminal

Switch(config)# macro global {apply | 
trace} macro-name [parameter {value}] 
[parameter {value}] [parameter 
{value}]

Switch(config)# macro global 
description text

Switch(config-if)# interface 
interface-id

Switch(config-if)# default interface 
interface-id

Switch(config-if)# macro {apply | 
trace} macro-name [parameter {value}] 
[parameter {value}] [parameter 
{value}]

Switch(config-if)# macro apply cisco-phone ?

  WORD  Keyword to replace with a value e.g. $AVID, $VVID

  <cr>

Switch(config-if)# macro description 
text

Switch(config-if)# end 

Switch# show parser macro 
description [interface interface-id]

Switch# copy running-config 
startup-config

You can delete a global macro-applied configuration on a switch only by entering the no version of each command that is in the macro. You can delete a macro-applied configuration on an interface by entering the default interface interface-id interface configuration command.

The no form of the macro name global configuration command deletes only 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:

•cisco-global

•cisco-desktop

•cisco-phone

•cisco-switch

•cisco-router
