Marking Bridged Traffic. You can configure one or more interfaces on a
the ProCurve Secure Router to act as a bridge. In effect, the router extends a
LAN throughout two or more remote sites. Traffic between hosts at each local
site can obviously travel faster than that between hosts at different sites. Local
hosts are not only physically closer, but they can also take advantage of higher-
speed Ethernet connections.
To mark bridged traffic, you must first match the QoS map entry to it. Enter:
ProCurve(config-qos-map)# match protocol bridge
To mark only NetBEUI traffic, which manages communications between hosts
in a LAN, enter:
ProCurve(config-qos-map)# match protocol bridge netbeui

Setting the ToS Value

After you have selected the traffic to be marked by the QoS entry, you enter a
set command to specify the value with which it will be marked.
The router can mark packets with an IP precedence or with a DiffServ value.
For example, you may want to match packets that have an IP precedence value
of 5 and change the IP precedence value to 4. Or you may want to assign VoIP
traffic (for example, traffic destined to UDP ports 16,384 to 20,000) an IP
precedence value of 5.
To mark packets matched to the QoS map entry with an IP precedence value,
enter:
Syntax: set precedence <0-7>
For example, set packets to critical priority:
ProCurve(config-qos-map)# set precedence 5
Although the ProCurve Secure Router itself does not support DiffServ except
as mapped to IP precedence, devices in the forwarding network may do so. In
this case, you should have the router mark packets that match the criteria you
have selected with the appropriate value for a PHB:
Syntax: set dscp <0-63>
For example, mark packets for Expedited Forwarding:
ProCurve(config-qos-map)# set dscp 46
