Chapter8 Configuring SDM Template s
Configuring the Switch SDM Template
Setting the SDM Template
Beginning in privileged EXEC mode, follow these steps to use the SDM template to maximize feature
usage:
After the system reboots, you can use the show sdm prefer privileged EXEC command to verify the
new template configuration. 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.
This is an example of an output display when you have changed the templa te and have not reloaded the
switch:
Switch# show sdm prefer
The current template is "desktop routing" 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: 3K
number of igmp groups + multicast routes: 1K
number of unicast routes: 11K
number of directly connected hosts: 3K
number of indirect routes: 8K
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 sdm prefer {access | default |
dual-ipv4-and-ipv6 {default | routing |
vlan} | routing | vlan}
Specify the SDM template to be used on the switch:
The keywords have these meanings:
•access—Maximizes system resources for ACLs.
•default—Gives balance to all functions.
•dual-ipv4-and-ipv6—Select a template that supports both IPv4
and IPv6 routing.
–
default—Balance IPv4 and IPv6 Layer 2 and Layer 3
functionality.
–
routing—Provide maximum usage for I Pv4 and IPv6
routing, including IPv4 policy-based routing.
–
vlan—Provide maximum usage for IPv4 and IPv6 VLANs.
•routing—Maximizes routing on the switch.
•vlan—Maximizes VLAN configuration on the switch with no
routing supported in hardware.
Use the no sdm prefer command to reset the switch to the default
desktop template. The default template balances the use of system
resources.
Step3 end Return to privileged EXEC mode.
Step4 reload Reload the operating system.
