Figure 13: Passing 802.1p Values to the DHCP Server

DHCP client
Sends DHCP packet
with assigned 802.1p
The following example describes a sample procedure that creates an environment
that passes 802.1p values to the DHCP server, which then assigns an IP address that
enables the desired service to the DHCP client.

Configuring DHCP Relay and BOOTP Relay
DHCP relay
Ingress VLAN policy Relay Agent copies
maps 802.1p UPC into option 82
(user priority) to UPC vendor-specific suboption
Configure a layer 2 policy that maps 802.1p values to user packet class values
for a VLAN interface.
