limits must be configured using the set port buffer threshold command as described in 

Use this command to enables or disable Head of Line (HOL) Blocking Prevention for one or more 
ports. HOL Blocking Prevention drops frames after a pre-defined number of frames are queued to 
a congested port. This prevents flow control from hampering other uncongested ports at the expense 
of dropping frames to the congested port.

Specifies the port(s) for which to enable or disable HOL 
Blocking Prevention. For a detailed description of possible 
port-string values, refer to 

.

ingress | egress

Enables or disables HOL Blocking Prevention on ingress 
(just entered the switch) or egress (in the system and before 
transmission) frames.

enable | disable

Enables or disables HOL Blocking Prevention.

NOTES: If switch ports are congested, disabling 
HOL Blocking Prevention without enabling flow 
control will result in frames being dropped at the 
ingress port (in addition to causing potentially 
unnecessary congestion inside the switch).
