Verify the dhcp-server-subnet with subnetgroup index matching the
bridgeConfigValue is configured to forward DHCP requests to the desired
external DHCP server. In this example, the bridgeConfigValue of 1 in the
bridge-config-record matches the subnetgroup value specified
in the dhcp-server-subnet profile. These values tell the DHCP relay
agent to send the DHCP packets to the specified DHCP external server
at 172.16.88.73.

COS in bridges
The EtherXtend supports setting COS values in Ethernet VLAN headers for
bridged packets. This service enables you to assign a service level or class of
service (COS) to an Ethernet VLAN interface that is transported across a
uplink, intralink, or downlinked tagged bridge. The configured COS level
specifies the packet priority and queueing methods used to transport the
packet through the Ethernet network. The EtherXtend sets and preserves the
COS settings to ensure these settings are passed to other Ethernet devices in
the network for QOS processing.
