When a station shuts down a VM, it sends a VDP de-associate packet to the bridge. The
bridge sends the request to the VSI manager, and the VSI manager notifies the bridge to
delete the VSI interface.
An EVB station and an EVB bridge perform the following steps to manage VM traffic:
1.
Use CDCP to establish an S-channel.
2.
Exchange EVB TLVs through LLDP to negotiate EVB capabilities such as RR, ECP parameters,
and VDP parameters for the S-channel.
3.
Use VDP to associate the VSIs of VMs with the bridge port.
