Resetting Dldp Status - H3C S7500 Series Operation Manual

Operation Manual – DLDP
H3C S7500 Series Ethernet Switches
Note:
When you use the dldp enable/dldp disable command in system view to
enable/disable DLDP globally on all optical ports of the switch, this command is only
valid for existing optical ports on the device, however, it is not valid for those added
subsequently.
DLDP can operate normally only when the same authentication mode and
password are set for local and peer ports.
When the DLDP protocol works in normal mode, the system can identify only one
type of unidirectional links: cross-connected fibers.
When the DLDP protocol works in enhanced mode, the system can identify two
types of unidirectional links: the first type is the cross-connected fiber, and the
second type is one of the two fibers is not connected or fails.
When the device is busy with services and the CPU utilization is high, DLDP may
issue mistaken reports. You are recommended to configure the operating mode of
DLDP as manual after unidirectional links are discovered.
For the dldp interval integer command, make sure that the same interval for
transmitting advertisement packets is set on the ports used to connected both
devices; otherwise DLDP will not operate properly.

1.3.2 Resetting DLDP Status

Note:
Only after the ports are DLDP down due to the detection of unidirectional links can you
use the dldp reset command to reset the DLDP status of these ports to retrieve DLDP
probes.
