Free edition of Cisco Nexus 1000v VMware virtual switch

Written by Roy Mikes on Tuesday, 23 October 2012. Posted in Cisco

Now available for download

As of this week Cisco announced there new version of the Cisco Nexus 1000V which is available for download.

The Cisco Nexus 1000V provides a distributed, Layer 2 virtual switch that extends across many virtualized hosts. The Cisco Nexus 1000V manages a data center defined by the vCenter Server. Each server in the data center is represented as a line card in the Cisco Nexus 1000V and can be managed as if it were a line card in a physical Cisco switch. The Cisco Nexus 1000V consists of the following two components:

• Virtual Supervisor Module (VSM), which contains the Cisco CLI, configuration, and high-level features.
• Virtual Ethernet Module (VEM), which acts as a line card and runs in each virtualized server to handle packet forwarding and other localized functions.

This version comes in two editions. A free version named Essential Edition and a paid named Advanced Edition. To upgrade to Advanced Edition a license needs to be applied.

When the Release 4.2(1)SV2(1.1) software is installed, the Essential edition is the default edition. When the switch is configured in the Essential edition, all the features (other than the advanced features) are available for free for unlimited time. No licenses are required to operate the Essential edition. The switch edition configuration is global and not per module. In Essential edition, all the modules are automatically licensed. Use the svs switch edition command to move the switch from the Essential edition to the Advanced edition and vice versa.

The servers that run the Cisco Nexus 1000V VSM and VEM must be in the VMware Hardware Compatibility list. This release of the Cisco Nexus 1000V supports vSphere 4.1.0, 5.0.0, and 5.1.0 release trains. For additional compatibility information, see the Cisco Nexus 1000V Compatibility Information, Release 4.2(1)SV2(1.1).

The most important note is, that all virtual machine network adapter types that VMware vSphere supports are supported with the Cisco Nexus 1000V.
