Cisco IOS XE Release 3.10SThis feature is used to optimizesystem resources in the routerto support specific featuresdepending on how the router isused in the network.

SDM Template

Prerequisites for the SDM TemplateBefore using an SDM template, you must set the license boot level.

Restrictions for the SDM Template• You cannot edit individual values in a template category as all templates are predefined.

• You cannot use a new SDM template without reloading the router.

• SDM templates are supported only by the Metro Aggregation Services license. Use the help option ofthe sdm prefer command to display the supported SDM templates.

• A mismatch in an SDM template between an active RSP and standby RSP results in a reload of thestandby RSP. During reload, SDM template of the standby RSP synchronizes with the SDM templateof the active RSP.

• To revert to the current SDM template after using the sdm prefer command (which initiates reload ofa new SDM template), you must wait for the reload to complete.

• Using the configure replace command which results in changes in the current SDM template is notsupported.

• The supported group numbers are for scaling in uni-dimension. When scaling in multi-dimension, thenumbers can vary as certain features may share resources.

•When scaling, features usingMultiprotocol Label Switching (MPLS) are limited by the number ofMPLSlabels.

• Internal TCAM usage reserved for IPv6 is 133-135 entries. TCAM space allotted for SDM template is135 entries on the router.

• EAID Exhaust occurs when two paths are MPLS and two are IP. It does not occur if all the four pathsare IP.

Information About the SDM TemplateThe SDM templates are used to optimize system resources in the router to support specific features, dependingon how the router is used in the network. The SDM templates allocate Ternary Content Addressable Memory(TCAM) resources to support different features. You can select the default template to balance system resourcesor select specific templates to support the required features.

The following table shows the approximate number of each resource supported in each of the templates fora router running the Metro Aggregation Services license on RSP1A.

17 From release 16.7.x the VPLS backup PW feature is supported, so if VPLS instance is configured then the maximum VPLS session is limited to 1000 insteadof 3500.

Selecting the SDM TemplateTo select an SDM template, complete the following steps:

SUMMARY STEPS

1. enable2. configure terminal3. sdm prefer {default | video | ip |mvpn_rsp1a | VPNv4/v6}

DETAILED STEPS

PurposeCommand or Action

Enables privileged EXEC mode.enable

Example:Router> enable

Step 1

• Enter your password if prompted.

Enters global configuration mode.configure terminal

Example:Router# configure terminal

Step 2

Specifies the SDM template to be used on the router.sdm prefer {default | video | ip |mvpn_rsp1a | VPNv4/v6}

Step 3

• default—Balances all functions.

Example:Router(config)# sdm prefer default

• video—Increases multicast routes and ACLs.

• ip—Increases IPv4/VPNv4 routes. This option is available only on RSP1A.

• mvpn_rsp1a—Supports MVPN. This option is available only on RSP1A.

• VPNv4/v6—Increases IPv4/VPNv4 routes. This option is available onlyon RSP1B.

When changing the SDM template, the router waits for two minutesbefore reloading. Do not perform any operation till the router reloads.

Note

For the new SDM template to take effect, you must save and reloadthe new configuration, otherwise the current SDM template is retained.

Note

Verifying the SDM TemplateYou can use the following show commands to verify configuration of your SDM template:


Configuring the SDM Template on the Cisco ASR 903 RouterSelecting the SDM Template

• show sdm prefer current—Displays information about the active SDM template.

Following is a sample output using the show sdm prefer current command to display the currenttemplate configured on the router:Router# show sdm prefer current

The current template is "video" template.

• show sdm prefer—Displays the resource numbers supported by the specified SDM template.
