Use one of the following templates for vcpu distribution: Extra heavy heavy heavy (default) normal heavy medium vcpu Distribution: Extra heavy The following table shows the vcpu distribution for the Extra heavy template.

2 vcpu Distribution: heavy Configuring the vcpu Distribution across the Data, Control and s /3 / / / /3 / / / /3 5 Using an Extra heavy template, a service plane app can obtain.5 full cores for its operation. Example: WAAS. vcpu Distribution: heavy The following table shows the vcpu distribution for the heavy template. Table : heavy vcpu Distribution /3 / /3 / /3 6 The heavy template allocates an extra core to the / services, compared to the heavy template (there is one core for the and another core for the ). If there is no application, the can utilize all of the resources ( cores). vcpu Distribution: heavy This heavy template is the default vcpu Distribution template. The following table shows the vcpu distribution for the heavy template. Table 3: heavy vcpu Distribution Cisco CSR 000v Series Cloud Services Router Software Configuration Guide

3 Configuring the vcpu Distribution across the Data, Control and s vcpu Distribution: normal /3 / / / /3 / / / /3 3 7 By default, the Cisco CSR 000v core allocation favors a larger data plane for performance. If there is no application, the can utilize the 's resources. vcpu Distribution: normal You can use the vcpu distribution for the normal template to force the Cisco CSR 000v to behave in the same way as before using a template for vcpu distribution. For example, after creating a Cisco CSR 000v VM using the heavy template for vcpu distribution, specified in the ovf-env.xml file, you can later use CLI commands in the normal template to override the XML file settings that were previously applied by the heavy template. vcpu Distribution: heavy The following table shows the vcpu distribution for the heavy template. Table : heavy vcpu Distribution /3 / /3 / /3 Using a heavy template, a application (such as Snort IPS) can use up to full cores for its operation. vcpu Distribution: medium The following table shows the vcpu distribution for the medium template.

4 How to Boot the Cisco CSR 000v with an OVA image Configuring the vcpu Distribution across the Data, Control and s Table 5: medium vcpu Distribution /3 / /3 / /3 6 How to Boot the Cisco CSR 000v with an OVA image To boot the Cisco CSR 000v with an OVA image, boot from a CDROM containing the ovf-env.xml file. This XML file contains the vcpu distribution templates. A template is simply an additional bootstrap property. For more information about bootstrap properties, see Bootstrapping the CSR Configuration. This is an example of the part of the XML file that specifies a medium template: <Property oe:key="com.cisco.csr000v.resource-template." oe:value="service_plane_medium"/> How to Configure vcpu Distribution across the Data, Control and s Enter the platform resource command on the Cisco CSR 000v to select a template for vcpu distribution. configure template platform resource template Example: Router# configure template Enter configuration commands, one per line. End with CNTL/Z. Router(config)# platform resource? control-plane-extra-heavy Use Extra Heavy template control-plane-heavy Use Heavy template data-plane-heavy Use Heavy template data-plane-normal Use Normal template service-plane-heavy Use Heavy template service-plane-medium Use Medium template Router(config)# platform resource service-plane-heavy After entering the platform resource command, you must reboot the Cisco CSR 000v to activate the template. Determine the Active vcpu Distribution Template To determine which template is being used for vcpu distribution, use the following command: Cisco CSR 000v Series Cloud Services Router Software Configuration Guide
