Privileged EXEC
Command History
Usage Guidelines
When you change the SDM template by using the
sdm prefer
global configuration command, you must
reload the switch for the configuration to take effect. If you did not reload the switch after entering the
sdm prefer
global configuration command, the
show sdm prefer
privileged EXEC command displays
the template in use and not the newly configured template.
The numbers displayed for each template represent an approximate maximum number for each feature
resource. The actual number might vary, depending on the actual number of other features configured.
Examples
This is an example of output from the
show sdm prefer
command, displaying the template in use:
Switch#
show sdm prefer
The current template is “desktop default” template.
The selected template optimizes the resources in
the switch to support this level of features for
8 routed interfaces and 1024 VLANs.
number of unicast mac addresses: 6K
number of igmp multicast routes: 1K
number of unicast routes: 8K
number of directly connected hosts: 6K
