Configuring SDM Templates
This chapter describes how to configure the Switch Database Management (SDM) templates on the Catalyst 2960 switch.
Note For complete syntax and usage information for the commands used in this chapter, see the command reference for this release.
This chapter consists of these sections:
•Understanding the SDM Templates
•Configuring the Switch SDM Template
Understanding the SDM Templates
You can use the SDM templates to configure system resources in the switch to optimize support for specific features, depending on how the switch is used in the network. You can select a template to provide maximum system usage for some functions or to use the default template to balance resources.
To allocate TCAM resources for different usages, the SDM templates prioritize system resources to optimize support for certain features. You can select SDM templates to optimize these features:
•QoS—The QoS template maximizes system resources for quality of service (QoS) access control entries (ACEs).
•Default—The default template gives balance to all functions.
Table 7-1 lists the approximate numbers of each resource supported in each template.
The rows in the table represent approximate hardware boundaries set when a template is selected. If a section of a hardware resource is full, all processing overflow is sent to the CPU, seriously impacting switch performance.
Configuring the Switch SDM Template
These sections contain this configuration information:
•SDM Template Configuration Guidelines
Default SDM Template
The default template is the default.
SDM Template Configuration Guidelines
When you select and configure SDM templates, you must reload the switch for the configuration to take effect.
Setting the SDM Template
Beginning in privileged EXEC mode, follow these steps to use the SDM template to maximize feature usage:
After the system reboots, you can use the show sdm prefer privileged EXEC command to verify the new template configuration. If you enter the show sdm prefer command before you enter the reload privileged EXEC command, the show sdm prefer command shows the template currently in use and the template that will become active after a reload.
Displaying the SDM Templates
Use the show sdm prefer privileged EXEC command with no parameters to display the active template.
Use the show sdm prefer [default | qos] privileged EXEC command to display the resource numbers supported by the specified template.
