Chapter 6 Configuring SDM Templates
Configuring the Switch SDM Template
Table 6-1 lists the approximate numbers of each resource supported in each of the four templates.
Note Although the resources allocated to features are the same in the routing and PBR templates, you must
use the PBR template when enabling PBR, and you cannot use the PBR template when VRFs are
configured on the switch.
.
The first eight rows in the tables (unicast MAC addresses through security ACEs) 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. The last row is a
guideline used to calculate hardware resource consumption related to the number of Layer 2 VLANs on
the switch.
Configuring the Switch SDM Template
This section describes how to configure the SDM template to be used on the switch. This section contains
this configuration information:
• Default SDM Template, page 6-2
• SDM Template Configuration Guidelines, page 6-3
• Setting the SDM Template, page 6-3
Default SDM Template
The default template for is the “default desktop” template.
