Step 2. Specify a default VSI manager. Command Remarks evb default-manager { { ip ip-address | ipv6 ipv6-address | name name } [ port port-number ] | local-server } By default, no default VSI manager is specified. Configuring VDP negotiation parameters After a station sends a VDP request other than a De-Associate request to the bridge, the bridge requests the VSI resources and policies from the VSI manager. If the bridge receives no response from the VSI manager before the VDP response-wait-delay time expires, the VDP negotiation fails. The VDP response-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 and bridge through EVB TLV. When a Pre-Associate, Pre-Associate with Resource Reservation, or Associate request from a station is successfully handled, the VSI manager notifies the bridge to create a VSI for the corresponding VM. Then the bridge starts a "VDP keepalive timer" for the VSI. If the bridge receives no keepalive from the station before the timer expires, it releases resources reserved for the association. The VDP keepalive time is calculated as: VDP keepalive time (seconds) = 1.5 × [ 2VDP keepalive + (2 × ECP maximum retransmission time + 1) × 2ECP retransmission ] × 10-5. The value of the VDP keepalive exponent is the larger of the values proposed by the station and bridge through EVB TLV. The ECP maximum retransmission time and ECP retransmission exponent are fixed to 3 and 16, respectively. To configure VDP negotiation parameters: Step 1. Enter system view. 2. Enter Ethernet interface view. 3. Configure the VDP resource-wait-delay timer exponent. 4. Configure the VDP keepalive timer exponent. Command system-view interface interface-type interface-number Remarks N/A N/A evb vdp timer resource-wait-delay exponent value The default is 20. evb vdp timer keepalive exponent value The default is 20. Configuring an S-channel Creating an S-channel An S-channel is automatically created by CDCP, and the system automatically saves the configuration in the configuration file on the bridge. You can also manually create an S-channel by performing this task. 5

Configuring VDP negotiation parameters
After a station sends a VDP request other than a De-Associate request to the bridge, the bridge requests
the VSI resources and policies from the VSI manager. If the bridge receives no response from the VSI
manager before the VDP response-wait-delay time expires, the VDP negotiation fails. The VDP
response-wait-delay time on the EVB bridge is calculated as:
VDP response-wait-delay time (seconds) = 2
VDP
resource-wait-delay
× 10

.
The value of the VDP resource wait-delay exponent is the larger of the values proposed by the station and
bridge through EVB TLV.
When a Pre-Associate, Pre-Associate with Resource Reservation, or Associate request from a station is
successfully handled, the VSI manager notifies the bridge to create a VSI for the corresponding VM. Then
the bridge starts a "VDP keepalive timer" for the VSI. If the bridge receives no keepalive from the station
before the timer expires, it releases resources reserved for the association. The VDP keepalive time is
calculated as:
VDP keepalive time (seconds) = 1.5 × [ 2
VDP
keepalive
+ (2 × ECP maximum retransmission time + 1) × 2

The value of the VDP keepalive exponent is the larger of the values proposed by the station and bridge
through EVB TLV. The ECP maximum retransmission time and ECP retransmission exponent are fixed to 3
and 16, respectively.

An S-channel is automatically created by CDCP, and the system automatically saves the configuration in
the configuration file on the bridge. You can also manually create an S-channel by performing this task.
