set port holbp

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.

set port holbp port-string {ingress | egress}{enable | disable}

Syntax Description

ingress | egress

enable | disable

Command Defaults

Command Type

Switch command.

HOL Priority Queue

Specifies the port(s) for which to enable or disable HOL

Blocking Prevention. For a detailed description of possible

port-string values, refer to

Enables or disables HOL Blocking Prevention on ingress

(just entered the switch) or egress (in the system and before

transmission) frames.

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).
