Each command is listed in detail, as follows:

config duld ports

Purpose To configure unidirectional link detection on ports.

Syntax

config duld ports [<portlist> | all] {state [enable | disable] |

mode [shutdown | normal] | discovery_time <sec 5-65535>}

Description

Unidirectional link detection Provides discovery mechanism based

on 802.3ah to discovery its neighbor. If the OAM discovery can

complete in configured discovery time, it concluDGS the link is

bidirectional. Otherwise, it starts detecting task to detect the link

status.

Parameters

[<portlist> | all] – Specifies a port, a range of ports or all ports to be

configured.

state [enable | disable] – Specifies the unidirectional link detection

status to be enabled or disabled.

mode [shutdown | normal] – Specifies the mode the unidirectional

link detection will be set to.

 shutdown – If any unidirectional link is detected, disable the

port and log an event.

 normal – Only log an event when a unidirectional link is

detected.

discovery_time <sec 5-65535> – Enter the discovery time value

here. This value must be between 5 and 65535.

Restrictions Only Administrator and operator-level users can issue this

command.
