Chapter 8 Configuring SDM Templates

Displaying the SDM Templates

This is an example of output from the show sdm prefer dual-ipv4-and-ipv6 routing command entered on a desktop switch:

Switch# show sdm	prefer dual-ipv4-and-ipv6 routing
The current template is "desktop IPv4 and IPv6 routing" template.
The selected template optimizes the resources in		the switch to support this level of
features for 8 routed interfaces and 1024 VLANs.
