Configuring Smartports Macros

This chapter describes how to configure and apply Smartports macros on the Catalyst 3750 switch.

Note For complete syntax and usage information for the commands used in this chapter, refer to the command reference for this release.

Understanding Smartports Macros

Smartports macros provide a convenient way to save and share common configurations. You can use Smartports 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 Smartports macro is a set of CLI commands that you define. Smartports macros do not contain new CLI commands; they are simply a group of existing CLI commands.

When you apply a Smartports macro on an interface, the CLI commands 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 the interface and are saved in the running configuration file.

Configuring Smartport Macros

You can create a new Smartports 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 range of interfaces.

This section includes information about:

•Default Smartports Macro Configuration

•Smartports Macro Configuration Guidelines

•Creating and Applying Smartports Macros

Default Smartports Macro Configuration

There are no default Smartports macros configured on the switch.

Smartports Macro Configuration Guidelines

Follow these guidelines when configuring macros on your switch:

•Do not use exit or end commands when creating a macro. This 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 a to 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 Smartports Macros

Beginning in privileged EXEC mode, follow these steps to create and apply 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. 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.

This example shows how to define the desktop-config macro for an access switch interface, apply the macro to Gigabit Ethernet port 2, add a description to the interface, and verify the configuration.

Switch(config)# macro name desktop-config

# Put the switch in access mode

switchport mode access

# Allow port to move to forwarding state quickly

spanning-tree portfast

# BPDUs should not be sent into the network

spanning-tree bpduguard enable

# Restrict the port to one address -- that of desktop

switchport port-security maximum 1

# Put all data traffic in vlan 1

switchport access vlan 1

@

Switch(config)# interface gigabitethernet1/0/2

Switch(config-if)# macro apply desktop-config

Switch(config-if)# macro description desktop-config

Switch(config-if)# end

Switch# show parser macro name desktop-config

Macro name : desktop-config

Macro type : customizable

macro description desktop-config

# Put the switch in access mode

spanning-tree portfast

# BPDUs should not be sent into the network

spanning-tree bpduguard enable

# Restrict the port to one address -- that of desktop

switchport port-security maximum 1

# Put all data traffic in vlan 1

Displaying Smartports Macros

To display the Smartports macros, use one or more of the privileged EXEC commands in Table 12-1.
