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.

n1000v# show license file sample.lic
sample.lic:
SERVER this_host ANY
VENDOR cisco
INCREMENT NEXUS1000V_LAN_SERVICES_PKG cisco 1.0 permanent 16 \
HOSTID=VDH=8449368321243879080 \
NOTICE="<LicFileID>sample.lic</LicFileID><LicLineID>0</LicLineID> \
<PAK>dummyPak</PAK>" SIGN=34FCB2B24AE8
 

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 .


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, please contact your Cisco Customer Support Account Team.

Prerequisites to License Troubleshooting

Before you begin troubleshooting licenses, verify the information in this checklist:

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

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

Problems with Licenses

The following are symptoms, possible causes, and solutions for problems with licenses.

Symptom
Possible Causes
Solution

When you power on a virtual machine with ports on a Cisco Nexus 1000V port group, the interfaces do not come up, but display the following status:

VEM Unlicensed

Not enough licenses were obtained to license the CPU sockets of all VEMs connected to the VSM.

1. Verify license usage.

show license usage license_name

See Example 4-4 on page 4-5

2. Determine the number of licenses required by viewing the sockets installed on the VEM.

show module vem license-info

See Example 4-2 on page 4-5

3. Contact your Cisco Customer Support Account Team to acquire additional licenses.

You see the following system message:

PLATFORM-2-PFM_LIC_WARN_EXP Syslog
 
2008 Dec 19 22:28:30 N1KV %PLATFORM-2-PFM_LIC_WARN_EXP: WARNING License for VEMs is about to expire in 1 days! The VEMs' VNICS will be brought down if license is allowed to expire. Please contact your Cisco account team or partner to purchase Licenses. To activate your purchased licenses, click on www.cisco.com/go/license.
