Attribute Meaning
setting is 0. The 0 setting causes the web-based interface to
never be automatically refreshed.
Bridge Entry
Timeout
Specify the appropriate bridge timeout for correct network
operation with the existing network infrastructure. The Bridge
Entry Timeout must be a longer period than the ARP (Address
Resolution Protocol) cache timeout of the router that feeds the
network.
An inappropriately low Bridge Entry Timeout setting may
lead to temporary loss of communication with some end
users.
Translation
Bridging
Optionally, you can configure the AP to change the source
MAC address in every packet it receives from its SMs to the
MAC address of the SM that bridged the packet, before
forwarding the packet toward the public network. If you do,
then:
• Not more than 10 IP devices at any time are valid to send
data to the AP from behind the SM.
• AP populates the Translation Table tab of its Statistics web
page, displaying the MAC address and IP address of all the
valid connected devices.
• Each entry in the Translation Table is associated with the
number of minutes that have elapsed since the last packet
transfer between the connected device and the SM.
• If 10 are connected and another attempts to connect:
o If no Translation Table entry is older than 255
minutes, the attempt is ignored.
o If an entry is older than 255 minutes, the oldest
entry is removed and the attempt is successful.
• the Send Untranslated ARP parameter in the General tab of
the Configuration page can be:
o Disabled, so that the AP overwrites the MAC
address in Address Resolution Protocol (ARP)
packets before forwarding them.
o Enabled, so that the AP forwards ARP packets
regardless of whether it has overwritten the MAC
address.
When this feature is disabled, the setting of the
Send Untranslated ARP parameter has no effect, because all
packets are forwarded untranslated (with the source MAC
address intact).
Send Untranslated If the Translation Bridging parameter is set to Enabled,
