For Frame Relay connections, packets are queued on the Frame Relay inter-
face. When one of the Frame Relay subinterfaces is part of a bridge group, you
can place bridged traffic in a low-latency queue to speed processing and
transmission. The queue also guarantees that the bridged traffic receives the
portion of the bandwidth it needs. Setting the maximum bandwidth for
packets in this queue also ensures that bridged traffic does not starve out non-
bridged traffic.
To select bridged traffic for the queue, enter:
Syntax: match protocol bridge [netbeui]
NetBEUI allows hosts to communicate within the LAN. To allow only this
traffic access to the low-latency queue, use the optional netbeui keyword.

Setting the Bandwidth Guaranteed the Queue

After you select which traffic the QoS map entry should place in the queue,
you must select how much bandwidth it should guarantee this queue. See
"Determining Bandwidth for the Queue" on page 8-32 for some general guide-
lines on arriving at this value.
Enter:
Syntax: priority {<bandwidth> [<burst>]} | percent <value> | unlimited]
The command gives you three options for allocating bandwidth to the queue:
specifying an absolute bandwidth in Kbps
specifying a percentage of the total bandwidth
allowing the queue unlimited bandwidth
The sections below describe these options in more detail. Before you allocate
bandwidth, you should plan for every queue that will be implemented in this
map. You can then determine how much bandwidth to assign to each queue.
If the map also implements CBWFQ, remember that the bandwidth for low-
latency queues is allocated first.
Allocating Guaranteed Absolute Bandwidth to a Low-Latency
Queue. The <bandwidth> value in the priority command is the maximum
bandwidth (in Kbps) guaranteed to the queue. The valid range for the band-
width in Kbps is 8 to 1,000,000.
For example, enter:
ProCurve(config-qos-map)# priority 512
