○3 : If the device doesn't receive any DLDP packets within 5 seconds, the DLDP link state will A E A transit to Advertisement. ○4 : After receiving a packet from an unknown neighbor, the device's link state will transit from A E A Active to Probe, and then send out several probe packets to detect the link state. ○5 : If the device receives echo packets from its peer device, the link state between them will be A E A tagged as bidirectionally linked and the DLDP state will transit from Probe to Advertisement. A device in the Advertisement state will send advertisement packets. ○6 : If the device receives no echo packets after a specified period of time, the link will be tagged A E A as unidirectional and the DLDP state will transit from Probe to Disable. This port will be shut down automatically or manually (depending on the Shut Mode configured). The typical bidirectional link detection process is ○2 → ○4 → ○5 , and the typical unidirectional link A E A A E A A E A detection process is ○2 → ○4 → ○6 .

You can also configure the refresh frequency of the port states and reset the certain port's DLDP state manually. Choose the menu Ethernet OAM→ DLDP→ DLDP to load the following page. 134

3
: If the device doesn’t receive any DLDP packets within 5 seconds, the DLDP link state will
transit to Advertisement.
4
: After receiving a packet from an unknown neighbor, the device’s link state will transit from
Active to Probe, and then send out several probe packets to detect the link state.
5
: If the device receives echo packets from its peer device, the link state between them will be
tagged as bidirectionally linked and the DLDP state will transit from Probe to Advertisement. A
device in the Advertisement state will send advertisement packets.
6
: If the device receives no echo packets after a specified period of time, the link will be tagged
as unidirectional and the DLDP state will transit from Probe to Disable. This port will be shut down
automatically or manually (depending on the Shut Mode configured).
The typical bidirectional link detection process is

, and the typical unidirectional link
detection process is

.
On the
DLDP
page, you can enable the DLDP state globally and configure the interval of the
advertisement packets and the port shutdown mode. You can also configure the refresh frequency
of the port states and reset the certain port’s DLDP state manually.
