Clone Settings for All Ports
After you have made
changes for the selected port, click this button to apply
the same changes to all ports. Then click
Save Changes
.
WARNING:
The
PoE
setting is also cloned. Ensure that
the same
PoE
setting suits all ports before you clone
the settings of the selected port.
Basic Settings for Port
Name
Enter a name for the port.
Port Status
To use this port, check the box.
Note:
If you disable a port, its
PoE
functionality
remains.
PoE
PoE is disabled by default on all ports. To output PoE
to the connected device, select
24V
or
48V
(
48V
available
only on the TOUGHSwitch PoE PRO). To disable PoE,
select Off
.
Note:
Before enabling PoE, check the specifications
of your airMAX, UniFi, legacy, or third-party devices
to ensure they support passive PoE and require the
available amount of voltage. The TOUGHSwitch PoE
offers 24V passive PoE, and the TOUGHSwitch PoE
PRO offers 24V or 48V passive PoE.
Link Speed, Mbps
By default,
Auto
is enabled. The
TOUGHSwitch automatically negotiates transmission
parameters, such as speed and duplex, with its
counterpart. In this process, the networked devices
first share their capabilities and then choose the fastest
transmission mode they both support.
Note:
Auto
applies only to speed and duplex, not
POE.
To manually specify the maximum transmission link speed
and duplex mode, select
100Mbps-Full
,
100Mbps-Half
,
10Mbps-Full
, or
10Mbps-Half.
Full-duplex mode allows
communication in both directions simultaneously.
Half-duplex mode allows communication in one direction
at a time, alternating between transmission and reception.
To achieve full performance with extra-long Ethernet
cables, ensure that you use CAT6-qualified cables and
interconnects.
Flow Control
Enabled by default.
Flow Control
allows
the port to manage data rates in case the sending and
receiving devices use different data transmission rates.
Ping Watchdog for Port
Ping Watchdog
is only for PoE-enabled ports. It configures
the device to continuously ping a user-defined IP address
(it can be the Internet gateway, for example). If it is
unable to ping under the user-defined constraints, then
the device will automatically turn off PoE on the port,
and then turn it back on. This option creates a kind of
“fail-proof” mechanism.
Ping Watchdog
is dedicated to continuous monitoring of
the specific connection to the remote host using the
Ping
tool. The
Ping
tool works by sending ICMP echo request
packets to the target host and listening for ICMP echo
response replies. If the specified number of replies is not
received, the tool reboots the device.
Port Ping Watchdog
Enables use of Ping Watchdog.
•
IP Address To Ping
Specify the IP address of the target
host to be monitored by
Ping Watchdog
.
•
Ping Interval
Specify the time interval (in seconds)
between the ICMP echo requests that are sent by
Ping
Watchdog
. The default value is
15
seconds.
•
Startup Delay
Specify the initial time delay (in seconds)
until the first ICMP echo requests are sent by
Ping
Watchdog
. The default value is
300
seconds.
The
Startup Delay
value should be at least 60 seconds
as the network interface and wireless connection
initialization takes a considerable amount of time if the
device is rebooted.
•
Failure Count
Specify the number of ICMP echo
response replies. If the specified number of ICMP echo
response packets is not received continuously,
Ping
Watchdog
will reboot the device. The default value is
3
.
•
Cut Power for
Specify the number of seconds this port
should pause PoE (if applicable). The default value is
5
seconds.
WARNING:
Cutting power during a firmware
upgrade can damage your device. Ensure that you
specify a safe
Ping Interval
.
