Introduction to the XNV Feature
The XNV feature, which is also known as Virtual Machine (VM) tracking, enables the ExtremeXOS software to support VM port movement, port configuration, and inventory on network switches. VM movement and operation on one or more VM servers is managed by a VM Manager (VMM) application. The XNV feature enables a network switch to respond to VM movement and report VM activity to network management software.
Identify a VM by its MAC address and authenticate the VM connection to the network.
Apply a custom port configuration in response to VM authentication.
Remove a custom port configuration when a VM FDB entry ages out.
Detect a VM move between switch ports or switches and configure the old and new ports appropriately.
To support VM mobility, the XNV feature requires that each VM use unique, static MAC and IP addresses. Switch port operation for a VM can be configured with a policy file or an ACL.
