Chapter12 Configuring Smartports Macros

Configuring Smartports Macros

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 t emp la tes to

create Smartports macros to build and deploy Cisco-recommended network designs an d configurations.

For more information about Cisco-recommended configuration templates, refer to this Smartports

website:

Configuring Smartports Macros

You can create a new Smartports macro or use an existing macro as a tem pl ate to c re ate a n ew macr o

that is specific to your application. After you create the macro, you can apply it globally to a switch or

to a switch interface or range of interfaces.

This section includes information about:

•Default Smartports Macro Configuration, page 12-2

•Smartports Macro Configuration Guidelines, page 12-3

•Creating Smartports Macros, page 12-4

•Applying Smartports Macros, page 12-5

•Applying Cisco-default Smartports Macros, page 12-6

Default Smartports Macro Configuration

There are no Smartports macros enabled.

cisco-phone Use this interface configuration macro when connecting a des ktop device suc h as a

PC with a Cisco IP Phone to a switch port. This macro is an extension of the

cisco-desktop macro and provides the same security and resiliency features, but with

the addition of dedicated voice VLANs to ensure proper treatment of delay-se nsitive

voice traffic.

cisco-switch Use this interface configuration macro when connecting an access switch and a

distribution switch or between access switches connected using GigaStack modules

or GBICs.

cisco-router Use this interface configuration macro when connecting the switch and a WAN

router.

cisco-lre-cpe Use this interface configuration macro to optimize performance when the switch is

installed in apartment buildings or hotels, or when it is used to deliver

Video-on-Demand (VoD), or multicast video.

1. Cisco-default Smartports macros vary depending on the software version running on your switch.
