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.
