6Step Command Remarksinterface view or Layer 2aggregate interface view.interface-number4. Enable LLDP on theinterface lldp enable By default, LLDP is enabled on aninterface.5. Configure the Nearestnon-TPMR Bridge agent forLLDP to operate in TxRxmode.lldp agent nearest-nontpmradmin-status txrx The default mode is disable.Specifying a default VSI managerWhen the bridge receives a VDP packet (except for de-associate packets) from a station, it obtainsVSI interface resources and policies for the station from the VSI manager specified in the VDPpacket.The VSI manager ID TLV in a VDP packet carries an IP address of a VSI manager. If the value for theTLV is 0, the VDP packet does not contain a VSI manager IP address. Perform this task to specify adefault VSI manager for the bridge.To specify a default VSI manager:Step Command Remarks1. Enter system view. system-view N/A2. Specify a default VSImanager.evb default-manager { { ipipv4-address | ipv6 ipv6-address |name name } [ port port-number ]| local-server }By default, no default VSImanager is specified.Configuring VDP negotiation parametersAfter a station sends a VDP request other than a De-Associate request to the bridge, the bridgerequests the VSI interface resources and policies from the VSI manager. If the bridge does notreceive a response from the VSI manager before the VDP response-wait-delay time expires, theVDP negotiation fails. The VDP response-wait-delay time on the EVB bridge is calculated by usingthe following formula:VDP response-wait-delay time (seconds) = 2 VDP resource-wait-delay × 10—5.The value of the VDP resource wait-delay exponent is the larger of the values proposed by thestation and bridge through EVB TLV.When a Pre-Associate, Pre-Associate with Resource Reservation, or Associate request from astation is successfully handled, the VSI manager notifies the bridge to create a VSI interface for thecorresponding VM. Then the bridge starts a VDP keepalive timer for the VSI interface. If the bridgedoes not receive a keepalive from the station before the timer expires, it releases resources reservedfor the association. The VDP keepalive time is calculated by using the following formula:VDP keepalive time (seconds) = 1.5 × [ 2VDP keepalive + (2 × ECP maximum retransmission time + 1) ×2 ECP retransmission ] × 10—5.The values assigned to the VDP keepalive exponent, the ECP maximum retransmission time, andthe ECP retransmission exponent are the larger of the values proposed for each by the station andbridge through EVB TLV.To configure VDP negotiation parameters:
