Deploying the Cisco Nexus 1000V Series VSM on the Cisco Nexus 1100 Series

The Cisco Nexus 1000V Series VSM is one of the VSBs that can be hosted on the Cisco Nexus 1100 Series
VSAs. Each VSM can manage a group of up to 64 Cisco VEMs. From a network management perspective, a VSM
and the VEMs make up a virtual switch. Support is provided for both Layer 2 and Layer 3 communication between
the VSMs on the Cisco Nexus 1100 Series VSA and the VEMs that it controls.
More information and recommendations about the use of Layer 2 and Layer 3 connectivity between VSMs and
VEMs can be found in the Cisco Nexus 1000V Series deployment guide.

VSM High Availablity

If the Cisco Nexus 1100 Series high-availability pair is successfully installed, it will automatically be deployed as a
redundant pair when a new Cisco Nexus 1000V Series VSB is created and enabled. The current Nexus 1000V
version is bundled as an ISO image and included in the Cisco Nexus 1100 Series bootflash:repository folder. This
image is copied to a new VSM service when it is created. After you have created the first VSM, you can use that
software image to create additional VSMs. You can upgrade VSMs to a new release of the Cisco Nexus 1000V
Series as needed independent of upgrading the underlying Cisco Nexus 1100 Series image.

redundancy configuration

Cisco Nexus 1000V Series Backup and Restore Procedures

a. Copy the running configuration often or whenever network the configuration has changed.
4. Power back on the secondary or standby VSM.

Restore Procedure

1. Completely remove the Cisco Nexus 1000V Series VSB if it is still on the Cisco Nexus 1100 Series VSA.
2. Create a new Cisco Nexus 1000V Series VSB.
a. Import a backup Cisco Nexus 1000V Series instance to the new VSB.
b. Verify that the Cisco Nexus 1000V Series instance is operational.
3. Restore the backup network configuration as the running configuration.
a. Verify that the port profiles and configurations are correct.
b. Verify that the virtual machines are connected to the appropriate port profiles.
