Default Description
10 Use this field to indicate the maximum number of heartbeat messages that
can be lost between neighboring mesh nodes. The supported range is
from 1 to 255.
12 Use this setting to optimize operation of the link metric algorithm.
Indicates the minimal RSSI value. If the RSSI value is below this threshold,
the link may be considered a subthreshold link. A sub-threshold link is one
whose average RSSI value falls below the configured link threshold.
If this occurs, the mesh node may try to find a better link on the same
channel and cluster (only neighbors on the same channel are considered).
The supported threshold is hardware dependent, with a practical range of
1 to 255.
startup- Use this setting to optimize operation of the link metric algorithm.
subthreshold
Specifies the method a mesh node uses to find a better uplink to create a
path to the mesh portal. Only neighbors
on the same channel in the same mesh cluster are considered.
Available options are:
reselect-anytime—Connected mesh nodes evaluate mesh links every
30 seconds. If a mesh node finds a better uplink, the mesh node
connects to the new parent to create an improved path to the mesh
portal.
reselect-never—Connected mesh nodes do not evaluate other mesh
links to create an improved path to the mesh portal.
startup-subthreshold—When bringing up the mesh network, mesh
nodes have 3 minutes to find a better uplink. After that time, each
mesh node evaluates alternative links only if the existing uplink falls
below the configured threshold level (the link becomes a sub-threshold
link). The reselection process is cancelled if the average RSSI on the
existing uplink rises above the configured link-threshold.
subthreshold-only—Connected mesh nodes evaluate alternative links
only if the existing uplink becomes a sub-threshold link.
NOTE: AirWave recommends using the default value.
distributed- Use this setting to optimize operation of the link metric algorithm.
tree-rssi
Specifies the algorithm used by a mesh node to select its parent.
Available options are:
best-link-rssi—Selects the parent with the strongest RSSI, regardless
of the number of children a potential parent has.
distributed-tree-rssi—Selects the parent based on link-RSSI and
node cost based on the number of children. This option evenly
distributes the mesh points over high quality uplinks. Low quality
uplinks are selected as a last resort.
NOTE: AirWave recommends using the default value.
Blank Each 802.11a and 802.11g radio profile references an Adaptive Radio
Management (ARM) profile. When you assign an active ARM profile to a
mesh radio, ARM's automatic power-assignment and channel-assignment
Blank features automatically select the radio channel with the least amount of
interference for each mesh portal, maximizing end user performance. In
earlier versions of this software, an AP with a mesh radio received its
beacon period, transmission power and 11a/11g portal channel settings
from its mesh radio profile. Mesh-access AP portals now inherit these
radio settings from their dot11a or dot11g radio profiles.
NOTE: Do not delete or modify mesh cluster profiles once you use them to
provision mesh nodes. You can recover the mesh point if the original
cluster profile is still available. Aruba recommends creating a new mesh
cluster profile if needed.
100 Define the beacon period supporting mesh profiles, as described for the
fields immediately above.
