LABEL
DESCRIPTION
Active
Enable the switch button to enable
ZULD
on the Switch.
Port
This field displays the port number.
*
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.
