Sdm Prefer - Cisco Catalyst 3750 Command Reference Manual

sdm prefer

sdm prefer
Use the sdm prefer global configuration command on the switch stack or on a standalone switch to
configure the template used in Switch Database Management (SDM) resource allocation. You can use a
template to allocate system resources to best support the features being used in your application. Use a
template to provide maximum system usage for unicast routing or for VLAN configurationor to change
an aggregator template (Catalyst 3750-12S only) to a desktop template. Use the no form of this
command to return to the default template.
Syntax Description default
routing
vlan
desktop
Defaults The default template provides a balance to all features.

Usage Guidelines You must reload the switch for the configuration to take effect. If you enter the show sdm prefer
command before you enter the reload privileged EXEC command, the show sdm prefer command
shows the template currently in use and the template that will become active after a reload.
Desktop switches support only desktop templates; an aggregator switch (Catalyst 3750-12S) supports
both desktop and aggregator templates. On an aggregator switch, if you do not enter the desktop
keyword, the aggregator templates are selected.
All stack members use the same SDM desktop or aggregator template, stored on the stack master. When
a new switch member is added to a stack, as with the switch configuration file and VLAN database file,
the SDM configuration that is stored on the stack master overrides the template configured on an
individual switch.
Catalyst 3750 Switch Command Reference
2-226
sdm prefer {default | routing | vlan} [desktop]
no sdm prefer
Sets the switch to use the default template (Catalyst 3750-12S only). This keyword
is not available on switches that do not allow the aggregator template (desktop
switches). On these switches, enter the no sdm prefer command to set the default
template.
Provide maximum system usage for unicast routing. You would typically use this
template for a router or aggregator in the middle of a network.
Provide maximum system usage for VLANs. This template maximizes system
resources for use as a Layer 2 switch with no routing.
Use only on a Catalyst 3750-12S switch (where aggregator templates are the
default), to select the default, routing, or VLAN desktop template.
Modification
