Chapter 8 Configuring SDM Templates
Configuring the Switch SDM Template
Setting the SDM Template
Beginning in privileged EXEC mode, follow these steps to configure an SDM template:
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 output when you have changed the template 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 multicast routes: 1K
number of unicast routes: 11K
number of directly connected hosts: 3K
number of indirect routes: 8K
number of qos aces: 0.5K
number of security aces: 1K
On next reload, template will be “desktop vlan” template.
To return to the default template, use the
no
sdm prefer
global configuration command.

Step 2
sdm prefer
{

|
dual-ipv4-and-ipv6
{

|
vlan
} |

vlan
}
Specify the SDM template to be used on the switch. The keywords have
these meanings:
•
access
—Maximize system resources for ACLs.
•
default
—Give 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 IPv4 and IPv6 routing,
including IPv4 policy-based routing.
–
vlan
—Provide maximum usage for IPv4 and IPv6 VLANs.
•
routing
—Maximize routing on the switch.
•
vlan
—Maximize 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.
Step 3
end
Return to privileged EXEC mode.
Step 4
reload
Reload the operating system.
