Table 190 Advanced Application > ZULD Status
LABEL DESCRIPTION
ZULD is.... This shows whether ZULD is enabled or disabled on the Switch.
Port This field displays the port number of the Switch.
Active This field displays whether ZULD is enabled on the port or not. ZULD must be enabled
to detect an unidirectional link by monitoring OAMPDUs.
Mode This field indicates what ZULD will do when a unidirectional link is detected. In
Normal mode, ZULD only sends a syslog and trap when it detects a unidirectional
link. In Aggressive mode, ZULD shuts down the port (puts it into an ErrDisable
state) as well as sends a syslog and trap when it detects a unidirectional link.
Probe Time Probe time is the length of time that ZULD waits before declaring that a link is
unidirectional. When the probe time expires, and one port (either on the Switch or the
connected device) still has not received an OAMPDU, then ZULD declares that the link
is unidirectional.
