Note: Dual-band support is available with Mesh
Point. When one radio is configured for Mesh
Point, both radios can provide service.
Radio settings for the root-AP and non-root APs
must match.

Channel Width Represents the desired channel width. The
channel width is set for all APs in a device group.
Available options include:
Auto – Channel width is calculated
automatically by the AP. It is displayed in the
user interface for informational purposes only.

Channel Plan Non-root APs are configured with Mesh ACS
(Automatic Channel Selection). This allows the
non-root AP to follow the channel and width of
the uplink AP. The non-root AP scans channels to
find the best path to a root AP. Preferred Root and
Preferred Neighbor settings influence the path to
the root AP.
Note: Upon upgrade from earlier revisions of
Extreme Campus Controller, non-root APs in a
mesh network are converted to Mesh ACS to
determine the best channel.
Note: Path Minimum and Path Threshold are settings that refer to values in the Mesh Route Table. They
are metric values determined by an algorithm that indicate when ACS scans for a better mesh point
radio channel.
The best route path algorithm includes elements such as hop count, data rates, RSSI, and loss rate. A
perfect score is 1179.

Path Minimum The minimum root path metric value is used to
evaluate the channel during the Mesh ACS scan
process. Only the mesh point with a root path
metric less than the minimum root path is
considered a candidate mesh point that can hop
to the mesh point root.
Valid values are 100-20000. Default value is 1000.
The lower metric value indicates a better quality
mesh link to the root.

Path Threshold The maximum root path metric value that
determines when to evaluate the mesh point radio
channel for a better path to the gateway. When
the current path metric value exceeds this
threshold, an ACS scan is triggered on the mesh
point. Valid values are 800-65535. Default value is
1500. Setting this value below 1500 will result in
more frequent channel scans.
