LABEL DESCRIPTION
Active Select this to enable ZULD on the Switch.
SLOT This field appears only in stacking mode. Click the drop-down list to choose the slot
number of the Switch in a stack.
Port This field displays the port number. In stacking mode, the first number represents the slot ID
and the second is the port number. Please note that the default stacking ports (the last
two ports of your Switch) cannot be configured. They are reserved for stacking only.
* 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.
