ARP table
Lists all the entries of the ARP (Address Resolution
Protocol) table currently recorded on the device.
ARP is used to associate each IP address to the unique
hardware address (MAC) of each device. It is important to
have unique IP addresses for each MAC or else there will
be ambiguous routes in the network.
IP Address
Displays the assigned IP address.
MAC Address
Displays the MAC address of the device.

button.
The Bridge table shows which bridge port the particular
station is associated with - in other words from which
interface (Ethernet or wireless ) the network device
(defined by MAC address) is reachable from. The AirRouter
will forward the packets to that port only (thus saving a lot
of redundant copies and transmits).
The aging timer shows the aging time for each address
entry (in seconds) - after particular time out, not having
seen a packet coming from a certain address, the bridge
will delete that address from the Bridge Table.
Routes
Lists all the entries in the system routing table, while the
device is operating in
Router
mode.
The list can be updated using the
Refresh
button.
AirOS examines the destination IP address of each data
packet traveling through the system and chooses the
appropriate interface to forward the packet to. The system
choice depends on static routing rules – entries, which
are registered in the system routing table. Static routes
to specific hosts, networks or default gateway are set up
automatically according to the IP configuration of all the
AirOS interfaces.
