Chapter6 Configuring SDM Templates

Configuring the Switch SDM Template

Table 6 -1 shows the approximate number of each resource supported in each of the two templates for a

switch running the metro IP access image. The values in the template are based o n eight routed interface s

and approximately 1024 VLANs and represent the 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:

•Default SDM Template, page 6-2

•SDM Template Configuration Guidelines, page 6-2

•Setting the SDM Template, page 6-3

The default template for a switch running the metro IP access image is the default template.

The default (and only) template supported on switches running the metro base or metro access image is

the layer-2 template.

Follow these guidelines when selecting and configuring SDM templates:

•You must reload the switch for the configuration to take effect.

•If you are using the switch for Layer 2 features only, select the layer-2 template.
