Use this command to configure buffer threshold settings for a group of ports. This command applies 
priority queue or buffer percentages to various types of ingress or egress thresholds, and can also 
be used to reset all thresholds back to default values. Ingress thresholds are used for buffer control 
at the point the frame enters the switch. Egress thresholds are used for buffer control at the point 
after the frame has been accepted into the system, and before it has been transmitted out the 
destination port. 

set port buffer threshold threshold portgroup {queue0 queue1 queue2 queue3 | 
receive-buffers xon-limit xoff-limit | unicast-per-port multicast router-block}

Sets the threshold type. Valid entries and their 
corresponding actions are:

IngressRx - controls frames entering the switch for a 
given port.

IngressHOL - drops all frames after the set percentage 
of buffers for the given priority queue are awaiting 
transmission to other port destinations.

IngressSoftHOL - drops frames marked as discardable 
after the set percentage of buffers for the given priority 
queue are awaiting transmission to other port 
destinations.

EgressUniPrio - sets buffer percentages per port, per 
priority queue for unicast traffic.

EgressMultiPrio - sets buffer percentages per port, per 
priority queue for multicast traffic.

EgressAllPrio - sets buffer percentages per port, per 
priority queue for multicast and unicast traffic.

EgressHOL - drops all frames after the set percentage of 
buffers for the given priority queue are waiting to be 
transmitted on their destination port queue.

EgressSoftHOL - drops frames marked as discardable 
after the set percentage of buffers for the given priority 
queue are awaiting transmission to other port.
