Table 51: Radio Properties (continued)

Field Description

Max Tx Power Determines the maximum power level that can be used by the

radio in dBm. The values are governed by compliance

requirements based on the country, radio, and antenna

selected, and will vary by AP.

DFS Fallback Channels Specify a 5GHz channel that the radio will adopt if DFS

(Dynamic Frequency Selection) fails. ExtremeWireless APs

support up to 9 channels.

The following setting is supported on ExtremeWireless access

point models AP3xx, AP4xx, and AP5xx that are conﬁgured for

a Centralized site.

Note: DFS is not recommended on a radio conﬁgured for Mesh.

• Return to conﬁgured channel after failed event. When

selected, the device returns to the conﬁgured radio channel

after a DFS failed event. When this option is enabled, the

following options display:

◦ DFS Revert Hold Time. The amount of time that a

device will stay on a fallback channel before returning to

the selected DFS channel. Valid values are 30 to 3600

minutes. The default value is 90 minutes.

◦ DFS Revert Client Aware. A threshold that determines if

the radio will revert back to the DFS channel after

moving to the conﬁgured channel. In addition to DFS

Revert Hold Time, the radio client count also has to drop

below the conﬁgured threshold.

If the number of clients using the radio channel is less

than the conﬁgured threshold, the radio will revert to the

DFS channel. Valid values are 1 – 255. The default value is

0. Zero indicates that the conditioning based on number

of clients is ignored.
