Sdm Prefer - Cisco ME 3400 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. If the switch is running the metro IP access image, you can use
a template to balance resources between Layer 2 and Layer 3 functionality, or you can maximize system
usage to support only Layer 2 features in hardware. You can also select the dual IPv4 and IPv6 template
to support IPv6 forwarding. Use the no form of this command to return to the default template.
The default and dual-ipv4-and-ipv6 keywords are visible only when the metro IP access image is
Note
installed on the switch.
Syntax Description default
layer-2
dual-ipv4-and-ipv6
{default | routing |
vlan}
Defaults
The default template provides a balance to all features.
On switches that are running the metro base image or the metro access image, only the layer-2 template
is supported.

shows the template currently in use and the template that will become active after a reload.
