Information About VDC Resource Templates

VDC resource templates set the minimum and maximum limits for shared physical device resources when you create the VDC. The Cisco NX-OS software reserves the minimum limit for the resource to the VDC. Any resources allocated to the VDC beyond the minimum are based on the maximum limit and availability on the device.

You can explicitly specify a VDC resource template or you can use the default VDC template provided by the NX-OS software. VDC templates set limits on the following resources:

•IPv4 route memory

•IPv6 route memory

•Port channels

•Switch Port Analyzer (SPAN) sessions

•VLANs

•Virtual routing and forwarding instances (VRFs)

Note The IPv4 and IPv6 route memory available for all VDCs on a physical device with 4 GB of memory is 256 MB. You can have approximately 11,000 routes, each with 16 next hops, in 13 MB of route memory. The show routing memory estimate routes number-of-routes next-hops number-of-next-hops command shows the amount of unicast RIB (IPv4 RIB and IPv6 RIB) shared memory needed to support the specified number of routes and next hops.

If you do not set a limit for a resource in a VDC resource template, the default limits for that resource are the same as those in the default VDC resource template. Table 2-1 and Table 2-2 list the default VDC resource template limits.

Licensing Requirements for VDC Templates

The following table shows the licensing requirements for this feature:

Product
License Requirement

DCNM

VDC templates require no license. Any feature not included in a license package is bundled with the Cisco DCNM and is provided at no charge to you. For a complete explanation of the DCNM licensing scheme, see the Cisco DCNM Fundamentals Configuration Guide, Release 4.1.

NX-OS

VDC templates require no license. Any feature not included in a license package is bundled with the Cisco NX-OS system images and is provided at no extra charge to you. For a complete explanation of the NX-OS licensing scheme, see the Cisco Nexus 7000 Series NX-OS Licensing Guide, Release 4.1.


Guidelines and Limitations

VDC templates have the following guidelines and limitations:

•VDC templates can only be created by the network administrator in the default VDC.

•You can create a maximum of 64 VDC templates.

Configuring VDC Resource Templates

The maximum amount of system resources assigned to a VDC is limited by the VDC resource template used when the VDC is created. You can create VDC resource templates to use when creating VDCs to use resource limits other than those provided in the default VDC resource template. You can create a maximum of 64 VDC resource templates.

Note If you do not set limits for a resource in a VDC resource template, the default limits are the limits for that resource in the default VDC resource template (see Table 2-1).

Figure 2-1 shows the Virtual Devices pane.

Adding a VDC Resource Template

You can add a VDC resource template. You can add a maximum of 64 resource templates.

BEFORE YOU BEGIN

Ensure that you have discovered the physical device using a username that has the network-admin role.

DETAILED STEPS

To add a VDC resource template, follow these steps:

Step 1 From the Feature Selector pane, choose Virtual Devices.

Step 2 From the Summary pane, double-click the device to display the list of VDCs.

Step 3 Click the default VDC with the icon.

Step 4 From the Details pane, click the Resource Templates tab.

Step 5 Right-click in the Details pane and choose Add Template from the pop-up menu.

Step 6 At the cursor, enter the new VDC resource template name and press the Enter key.

Step 7 From the menu bar, choose File > Deploy to apply your changes to the device.

Adding a Resource Limit to a VDC Resource Template

You can add a resource limit to a VDC resource template.

Note You cannot change the configuration of the default templates.

BEFORE YOU BEGIN
