Configure the Switch
(Available for the EdgeRouter PoE only.) After you click
Config, the Interface Configuration screen appears.
Make changes as needed.
Description Enter keywords to describe this switch.
Address Select one of the following:
No address settings The switch uses no address
settings. (In most cases, an address is needed.)
Use DHCP The switch acquires network settings from
a DHCPv4 server. Click the Renew button to acquire
fresh network settings.
Use DHCP for IPv6 The switch acquires network
settings from a DHCPv6 server.
Manually define IP address(es) Enter the
static IP address (example: 192.0.2.1/24 for IPv4
or 2001:db8::1/32 for IPv6). Click Add IP to enter
additional IP addresses.
Switch Ports Select the ports for the switch interface.
Proxy ARP Enable the EdgeRouter to answer a source
host’s ARP (Address Resolution Protocol) requests for
the IP address of a destination host that is not located
on the source host’s network. ARP allows hosts on the
same network to discover each other’s IP address via a
layer 2 broadcast to all MAC addresses. If they are not on
the same network, the layer 2 broadcast will not reach
its destination; however, the EdgeRouter can serve as
the go‑between if Proxy ARP is enabled.
Click Save to apply your changes, or click Cancel.
Configure the PoE Settings
Note: Before enabling PoE, check the specifications
of your airMAX, airVision, mFi, UniFi, legacy, or
third‑party devices to ensure they support passive
PoE and require the available amount of voltage.
(Available for the EdgeRouter PoE only.) After you click PoE,
the PoE tab of the Interface Configuration screen appears.
PoE is disabled by default on all ports. Make changes as
needed.
PoE Select one of the following:
Off To disable PoE, select Off.
Note: To disable PoE, you must use this setting. If
you disable a port, its PoE functionality remains.
24V To output 24V PoE to the connected device,
select 24V.
48V To output 48V PoE to the connected device,
select 48V.
Note: You must have a 48V power adapter
(not included) powering the EdgeRouter PoE;
otherwise, 48V PoE is not allowed.
PoE Watchdog
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.
