3. Configure the Channel, Power and Rate Settings field to assign a channel, antenna
diversity setting, radio transmit power level and data rate.
ERP Protection Extended Rate PHY (ERP) allows 802.11g MUs to interoperate with
802.11b only MUs. ERP Protection is managed automatically by the
access point and informs users when 802.11b MUs are present
within the access point’s coverage area. The presence of 802.11b
MUs within the 802.11g coverage area negatively impacts network
performance, so this feature should looked to as an indicator of
why network performance has been degraded.
HT Protection Displays the HT Protection state, and whether a non HT protected
MU is currently associated with the access point.
802.11 b/g/n mode For radio1, specify B, G and N , B and G , G Only , B only or N Only
to define whether the 802.11b/g/n radio transmits in the 2.4 Ghz
band exclusively for 802.11b (legacy) clients or transmits in the 2.4
Ghz band for 802.11g/n clients. Selecting b and g enables the
access point to transmit to both b and g clients if legacy clients
(802.11b) partially comprise the network. Select accordingly based
on the MU requirements of the network.
The rates for the access point’s 2.4 GHz radio are as follows:
B, G and N - Allows only basic rates (default setting).
B and G - Allows 11b basic rates. Does not allow MCS rates.
G and N - Requires basic rates (either 6, 12, 24 or 1, 2, 5.5, 11, 6,
12, 24).
G Only - Requires one 11g basic rate. Does not allow MCS rates.
B Only - Allows for 11b rates only. Does not allow G or N rates.
N Only - Requires basic MCS rates.
Note: If the mode is B and G, the Channel Width option is not
available, and a Secondary Channel cannot be defined.
For the 5 GHz radio, specify A and N , A Only or N Only to define
whether the 802.11a/n radio transmits in the 5 Ghz band
exclusively for 802.11a clients, 802.11n clients or transmits in the
5 Ghz band for both 802.11a/n clients.
A Only - Allows 11a rates.
N Only - Requires basic MCS rates.
A and N - Allows only 11a basic rates (default setting).
