Sdm Prefer - Cisco catalyst 3750 Command Reference Manual

sdm prefer

sdm prefer
Use the sdm prefer global configuration command 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 configuration, to change an aggregator template (Catalyst 3750-12S
only) to a desktop template, or to select the dual IPv4 and IPv6 template to support IPv6 forwarding. Use
the no form of this command to return to the default template.

[desktop]
no sdm prefer
Provide maximum system usage for access control lists (ACLs). Use this
template if you have a large number of ACLs.
Sets the switch to use the default template. On Catalyst 3750-12S switches, use
with the desktop keyword to set the switch to the default desktop template. (Use
the no sdm prefer command to set a desktop switch to the default desktop
template or to set an aggregator switch to the default aggregator template.)
Select a template that supports both IPv4 and IPv6 routing.
• default—Provide balance to IPv4 and IPv6 Layer 2 and Layer 3
functionality.
routing—Provide maximum system usage for IPv4 and IPv6 routing,
•
including IPv4 policy-based routing.
vlan—Provide maximum system usage for IPv4 and IPv6 VLANs.
•
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 desktop default, routing, or vlan template.
