Enabled on the LAN SETTINGS screen. If you disable STP on a
non-root Bridge, the Multicast field for the radio with a Radio
Mode setting of Bridge and a Bridge Mode setting of Non-Root
will be configurable. Refer to Section 3.2.1 for more information
on STP.
3.3.2.7 Received Signal Strength Indicator
NOTE: Because ra-
dios in
AP Radio
Mode or in Root Bridge
Mode accept multiple, si-
multaneously connec-
tions, the LED RSSI
Monitor is not used to set
up radios configured in
this way (although it re-
mains available).
In outdoor, point-to-point/multipoint installations, the LED RSSI
Monitor allows you to make the first adjustments to the
directional antenna(s) of the non-root Bridge(s) in the network.
When the LED RSSI Monitor is Enabled on a given radio, all
other monitoring functions of both of the front-panel LEDs for
that radio (described in Section 5.6.2) are disabled.
Then, as you point a directional antenna of a non-root Bridge
toward the root Bridge, the lower LED for that radio dynamically
indicates the strength of the signal received from the root
Bridge, as shown in Table 3.1.
The LED RSSI Monitor is Disabled by default.
3.3.3 Configuring Basic Radio Settings
1Log on to the Bridge GUI admin account and select RADIO
SETTINGS from the menu on the left.
2On the RADIO SETTINGS screen, in the column that
corresponds to the radio you want to configure, enter new
values into the relevant fields (described in sections 3.3.1
and 3.3.2).
NOTE: When you
change TxPower
from Auto to another
value, the change takes
effect immediately.
When you change the
setting from another
value to
Auto, you must
reboot Bridge in order
to effect the change.
3Click Apply at the bottom of the screen.
4If a system prompt instructs you to reboot, click OK.
5If you changed TxPower to Auto, or you were prompted to
reboot the Bridge, follow the instructions in Section 4.7.
3.3.4 Virtual Radio Interface Settings
A radio with a radio mode of Bridge, whether it is configured as
a root or a non-root bridge, can comprise only a single Virtual
Access Point (or VAP), with its single associated SSID.
A radio with a radio mode of AP, can comprise up to four VAPs
each with its own SSID and associated settings.
By default, only one VAP is configured per radio, regardless of
the radio Mode settings. You can however observe the added,

Behavior Meaning
off no connection
slow green flash (approx. 1 Hz) poor connection (signal level ≤ -85 dBm)
fast green flash (approx. 4 Hz) good connection (signal level > -85 dBm but < -60 dBm)
steady green excellent connection (signal level > -60 dBm)
