Increase the value of this parameter if you notice that the LRM is discarding
packets because applications generating reserved traffic are exceeding their
flowspecs.
Specifying the Unreserved Policing Algorithm
LRM uses one of two policing algorithms for unreserved traffic.
• Queue Limit -- Restricts the number of buffers (packets) of unreserved traffic
that LRM queues.
This method of policing enables unreserved traffic to use available reserved
bandwidth. Set the Unreserved Queue Length parameter to specify the
maximum number of packets in the queue.
• Leaky Bucket -- Causes the router to actively police the unreserved traffic
based on the unreserved bandwidth.
This method does not allow unreserved traffic to take advantage of available
reserved bandwidth.
You can set the Unreserved Policing Algorithm for this interface.
Specifying the Unreserved Queue Length
If the Unreserved Policing Algorithm parameter is set to Queue Limit, you can
specify the maximum number of unreserved (best-effort) packets to be held in
queue for transmission. After the queue length reaches this value, the router
discards best-effort traffic when congestion occurs.
Note that Priority queuing limits, if configured, override the value of this
parameter.

Note: If you enable priority queuing for this line, the router uses the priority
queue parameters to perform Queue Limit policing. See Configuring Traffic
Filters and Protocol Prioritization for information about priority queue
parameters.
