5Specifying a default VSI managerWhen the bridge receives a VDP packet (except for a De-Associate packet) from a station, it contacts theVSI manager specified in the VDP packet to get VSI interface resources and policies.The VSI manager ID TLV in a VDP packet carries the VSI manager's IP address. If the value for the TLV is0, the VDP packet does not contain a VSI manager's IP address, so the bridge communicates with thespecified default VSI manager.To specify a default VSI manager:Step Command Remarks1. Enter system view. system-view N/A2. Specify a default VSImanager.evb default-manager { { ipip-address | ipv6 ipv6-address |name name } [ port port-number ] |local-server }By default, no default VSI manageris specified.Configuring VDP negotiation parametersAfter a station sends a VDP request other than a De-Associate request to the bridge, the bridge requeststhe VSI interface resources and policies from the VSI manager. If the bridge receives no response from theVSI manager before the VDP response-wait-delay time expires, the VDP negotiation fails. The VDPresponse-wait-delay time on the EVB bridge is calculated as:VDP response-wait-delay time (seconds) = 2VDP resource-wait-delay × 10—5 .The value of the VDP resource wait-delay exponent is the larger of the values proposed by the station andbridge through EVB TLV.When a Pre-Associate, Pre-Associate with Resource Reservation, or Associate request from a station issuccessfully handled, the VSI manager notifies the bridge to create a VSI interface for the correspondingVM. Then the bridge starts a "VDP keepalive timer" for the VSI interface. If the bridge receives nokeepalive from the station before the timer expires, it releases resources reserved for the association. TheVDP keepalive time is calculated as:VDP keepalive time (seconds) = 1.5 × [ 2 VDP keepalive + (2 × ECP maximum retransmission time + 1) × 2 ECPretransmission ] × 10—5 .The value assigned to the VDP keepalive exponent, the ECP maximum retransmission time, and the ECPretransmission exponent are the larger of the values proposed for each by the station and bridge throughEVB TLV.To configure VDP negotiation parameters:Step Command Remarks1.
