LABEL DESCRIPTION
Active Select this to enable ZULD on the Switch.
Port Use port * to configure all ports to have the same settings. Alternatively, select individual ports
for different settings.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to
set the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Active Select this to enable ZULD on the port. ZULD must be enabled to detect an unidirectional link
by monitoring OAMPDUs.
Mode Select Normal or Aggressive. 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 Type 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.
The allowed time range is from 5-65535 seconds.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
Cancel Click this to reset the values in this screen to their last-saved values.
