This chapter describes how to identify and resolve problems related to licenses.

Information About Licenses

The name for the Cisco Nexus 1000V license version 3.0 package is NEXUS1000V_LAN_SERVICES_PKG. By default, 1024 licenses are installed with the Virtual Supervisor Modules (VSM). These default licenses expire after 60 days. You can purchase permanent licenses that do not expire.

Licensing is based on the number of CPU sockets on the Microsoft Hyper-V servers attached as Virtual Ethernet Modules (VEMs) to the VSM.

A module is either licensed or unlicensed:

• Licensed module—A VEM is licensed if it acquires licenses for all of its CPU sockets from the pool of available licenses installed on the VSM.
• Unlicensed module—A VEM is unlicensed if it does not acquire licenses for all of its CPU sockets from the pool of available licenses installed on the VSM.

If a VEM is unlicensed, the virtual Ethernet ports corresponding to the Virtual Machines (VMs) are kept down and are shown as unlicensed.

Note The server administrator has no information about VEM licenses. The VEM licensed state must be communicated to server administrators so that they are aware that vEthernet interfaces on unlicensed modules cannot pass traffic.

For additional information about licensing, including how to purchase or install a license, or how to remove an installed license, see the Cisco Nexus 1000V for Microsoft Hyper-V License Configuration Guide.

Contents of the License File

The contents of the Cisco Nexus 1000V license file contents indicate the number of licenses purchased and the host ID. To display the contents of a license file, use the show license file license_name command.

The host ID that appears in the license file must match the ID that is shown on the VSM. To verify that the IDs match, use the show license host-id command. See Example 5-6 on page 5-6 .

Caution Do not edit the contents of the license file. The license is invalidated if its contents are altered. If you have already done so, contact your Cisco Customer Support Account Team.

Prerequisites to License Troubleshooting

Before you begin troubleshooting licenses, verify the following information:

• Make sure that the name of the license file is less than 32 characters.

Check the name by entering the show license command. See Example 5-3 on page 5-5 .

• Make sure that no other license file with the same name is installed on the VSM. If there is a license file with the same name, rename your new license file to something else.

Check the name by entering the show license brief command. See Example 5-3 on page 5-5 .

• Do not edit the contents of the license file. If you have already done so, contact your Cisco Customer Support Account Team.
• Make sure that the host ID in the license file is the same as the host ID on the switch by entering the following commands:

– show license host-id. See Example 5-6 on page 5-6 .

– show license file. See Example 5-7 on page 5-6
