Release Notes

Parameter Description Range Default
tpc-power
The transmit power advertised in
the TPC IE of beacons and probe
responses. Range: 0-51 dBm
0-51 dBm 15 dBm
tx-power
Sets the initial transmit power
(dBm) on which the AP operates,
unless a better choice is available
through calibration.
This parameter can be set from 0
to 51 in .5 dBm increments, or set
to the regulatory maximum value
of 127 dBm.
Transmission power may be
further limited by regulatory
domain constraints and AP
capabilities.

very-high-throughput-rates-
enable
This feature enables Very High
Throughput (VHT) rates on the 2.4
GHz band, providing 256-QAM
modulation and encoding that
allows for 600 Mbit/sec
performance over 802.11n
networks. Maximum data rates are
increased on the 2.4 GHz band
through the addition of VHT
Modulation and Coding Scheme
(MCS) values 8 and 9, which
support the highly efficient
modulation rates in 256-QAM.
Starting with ArubaOS 6.4.2.0, VHT
is supported on W-AP220 Series
access points on both 20 and 40
MHz channels.
Using the controller’s CLI or WebUI,
VHT MCS values 0-9 are enabled,
overriding the existing high-
throughput (HT) MCS values 0-7,
which have a lower maximum data
rate. However, this feature should
be disabled if individual rate
selection is required.

Usage Guidelines
This command configures radios that operate in the 2.4 GHz frequency band, which includes radios utilizing
the IEEE 802.11b/g or IEEE 802.11n standard. Channels must be valid for the country configured in the AP
regulatory domain profile (see ap regulatory-domain-profile on page 182).To view the supported channels, use
the show ap allowed-channels command.
APs initially start up with default ack-timeout, cts-timeout and slot-time values. When you modify the
maximum-distance parameter in an rf dot11a radio profile or rf dot11g radio profile, new ack-timeout, cts-
timeout and slot-time values may be derived, but those values are never less then the default values for an
indoor AP.
Mesh radios on outdoor APs have additional constraints, as mesh links may need to span long distances. For
mesh radios on outdoor APs, the effect of the default maximum-distance parameter on the ack-timeout,
cts-timeout and slot-time values depends on whether the APs are configured as mesh portals or mesh
