Parameter Description Range Default
spur-immunity <spur-
immunity>
Spur Immunity for 5 GHz radio. This
parameter fine-tunes the Cyclic Power
Threshold (CPT) of a 5 GHz radio. The
value specified here is the offset from the
base value of 2 dB (for example, setting
the CPT value to 1 corresponds to 2 + 1 = 3
dB. Similarly, setting the CPT value to 10
corresponds to 2+10 = 12 dB).
Use this parameter when high channel
utilization is observed in the 5 GHz radio
of W-AP130 Series access points in a
noise-free environment causing client
association or throughput issues.
Adjust the CPT value to eliminate the spur
impacts. Range definition is as follows:
l 0: default CPT
l 1-19: CPT growth from default (3 dB to
21 dB)
l 20: Setting this parameter to 20 sets
the cell-size-reduction value to 1. Cell-
size-reduction is the receive coverage
area of the AP.
NOTE: Configure this parameter under
the supervision of Dell Technical Support.
NOTE: Setting the spur immunity to a
higher value may decrease the AP RF
coverage.
NOTE: This parameter is applicable for W-
AP130 Series access points only. The
controller ignores this parameter if
configured for non-W-AP130 Series access
points.
0-20 CPT 0 CPT
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-

Enable or disable support for Very High
Throughput (802.11ac) on the radio.
