LABEL
DESCRIPTION
Active
Select this option to enable Auto PD Recovery on the Switch.
Port
This field displays the index number of a port on the Switch.
*
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.
Changes in this row are copied to all the ports as soon as you make them.
Active
Select
Active
to enable Auto PD Recovery on the ports.
Mode
Select
LLDP
to have the Switch passively monitor current status of the connected PD by
reading LLDP packets from the PD on the port. The Switch also sends out LLDP packets to the
PD to update the
Switch Neighbor
table on the PD (see
for details).
Select
Ping
to have the Switch ping the IP address of the connected PD to test whether the
PD is reachable or not.
Neighbor
If
Mode
is set to
LLDP
, the system name of the connected PD displays automatically.
If
Mode
is set to
Ping
and the PD supports LLDP, the connected PD’s IPv4 or IPv6 address to
which the Switch sends ping requests will display automatically. If not, enter the IP address
manually.
Polling Interval
Specify the number of seconds the Switch waits for a response before sending another ping
request.
For example, the Switch will try to detect the PD status by performing ping requests every 20
seconds.
Polling Count
Specify how many times the Switch is to resend a ping request before considering the PD
unreachable.
For example, If there is no ping reply from the PD after the
Polling Interval
has elapsed,
Polling
Count
starts from 1. After
Polling Count
reaches 3, the
PD Health
status LED will turn to red in
the
Status
>
Neighbor
screen (see
for details). The Switch will then
perform your choice in the
Action
field.
