Licenses
This chapter describes how to identify and resolve problems related to licenses, and includes the following sections.
Information About Licenses
The name for the Cisco Nexus 1000V license package is NEXUS1000V_LAN_SERVICES_PKG. By default, 16 licenses are installed with the VSM. These default licenses are valid for 60 days. You can purchase permanent licenses that do not expire.
Licensing is based on the number of CPU sockets on the ESX servers attached as 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 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 License Configuration Guide, Release 4.2(1)SV2(1.1).
Contents of the License File
The contents of the Cisco Nexus 1000V license file indicates 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 that shown on the VSM. To verify this, use the show license host-id command. See Example 4-6 on page 4-6 .
Prerequisites to License Troubleshooting
Before you begin troubleshooting licenses, verify the information in this checklist:
Use the show license usage command. See Example 4-3 on page 4-5 .
- Make sure 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.
Use the show license usage command. See Example 4-3 on page 4-5 .
- Do not edit the contents of the license file. If you have already done so, please contact your Cisco Customer Support Account Team.
- Make sure the host-ID in the license file is the same as the host-ID on the switch, using the following commands:
show license host-id See Example 4-6 on page 4-6 .
show license file See Example 4-7 on page 4-6
