config duld ports [<portlist> | all] {state [enable | disable] | mode [shutdown | normal] |
discovery_time <sec 5-65535>}(1)
show duld ports {<portlist>}
23-1 config duld ports
Description
The command is used to configure unidirectional link detection on ports. 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 concludes the link is bidirectional.
Otherwise, it starts detecting task to detect the link status.
Format
config duld ports [<portlist> | all] {state [enable | disable] | mode [shutdown | normal] |
discovery_time <sec 5-65535>}(1)
Parameters
<portlist> - Specifies a range of ports.
all - Specifies to select all ports.
state - Specifies these ports unidirectional link detection status.
enable - Enables unidirectional link detection status.
disable - Disables unidirectional link detection status.
mode - Specifies the mode when detecting unidirectional link.
shutdown - If any unidirectional link is detected, disables the port and logs an event.
normal - Only logs an event when a unidirectional link is detected.
discovery_time - Specifies these ports neighbor discovery time. If OAM discovery cannot
complete in the discovery time, the unidirectional link detection will start.
<sec 5-65535> - Enter a time in second. The default discovery time is 5 seconds.
Restrictions
Only Administrators, Operators and Power-Users can issue this command.
