3{ When a station shuts down a VM, it sends a VDP de-associate packet to the bridge. Thebridge sends the request to the VSI manager, and the VSI manager notifies the bridge todelete 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.Protocols and standardsIEEE P802.1Qbg/D2.2, Draft Standard for Local and Metropolitan Area Networks—MAC Bridgesand Virtual Bridged Local Area Networks - Amendment XX: Edge Virtual BridgingFeature and hardware compatibilityEVB is applicable only to interfaces on the following modules:• EC interface modules.• SE interface modules:{ LSU1CGC2SE0.{ LSUM2GP24TSSE0.{ LSUM2GP44TSSE0.{ LSUM2GT24PTSSE0.{ LSUM2GT24TSSE0.{ LSUM2GT48SE0.{ LSUM2GV48SE0.• SF interface modules.• SG interface modules.Traffic received from an EVB-enabled interface can be forwarded only through interface modulesthat support EVB.Licensing requirementsEVB requires a license to run on the device.
