Chapter 6 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 on eight routed interfaces
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
Default SDM Template
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.
SDM Template Configuration Guidelines
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.
