Configuring Vdp Negotiation Parameters; Configuring An S-Channel; Creating An S-Channel - HP 6125XLG Configuration Manual

Step
2. Specify a default VSI
manager.

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
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
retransmission ] × 10
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.

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.
