Information About Licenses
The name for the Cisco Nexus 1000V license package is NEXUS1000V_LAN_SERVICES_PKG and the version is 3.0. By default, 1024 licenses are installed with the Virtual Supervisor Module (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 Virtual Ethernet Modules (VEM) 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 correspond to the virtual machines (VMs) that are kept down and are shown as unlicensed.
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, install, or remove an installed license, see the Cisco Nexus 1000V License Configuration Guide.
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 command.
