Parameter Description Range Default
mpv This parameter is experimental and reserved for
future use. 0-4094 0 (disabled)
no
Negates any configured parameter. — —
reselection-mode
Specifies the method used to find a better mesh link.
Best practices are to use the default value startup-
subthreshold. (see below) startup-sub
threshold
reselect-anytime
Mesh points using the reselect-anytime reselection
mode perform a single topology readjustment scan
within 9 minutes of startup and 4 minutes after a link
is formed. If no better parent is found, the mesh point
returns to its original parent. This initial scan
evaluates more distant mesh points before closer
mesh points, and incurs a dropout of 5-8 seconds for
each mesh point.
After the initial startup scan is completed, 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 Mesh points using the startup-subthreshold
reselection mode perform a single topology
readjustment scan within 9 minutes of startup and 4
minutes after a link is formed. If no better parent is
found, the mesh point returns to its original parent.
This initial startup scan evaluates more distant mesh
points before closer mesh points, and incurs a
dropout of 5-8 seconds for each mesh point. After that
time, each mesh node evaluates alternative links if
the existing uplink falls below the configured
threshold level (the link becomes a sub-threshold
link). Best practices are to use the default startup-
subthreshold value.
NOTE: Starting with ArubaOS 3.4.1, if a mesh point
using the startup-subthreshold mode reselects a more
distant parent because its original, closer parent falls
below the acceptable threshold, then as long as that
mesh point is connected to that more distant parent, it
will seek to reselect a parent at the earlier distance
(or less) with good link quality. For example, if a mesh
point disconnects from a mesh parent 2 hops away
and subsequently reconnects to a mesh parent 3 hops
away, then the mesh point will continue to seek a
connection to a mesh parent with both an acceptable
link quality and a distance of two hops or less, even if
the more distant parent also has an acceptable link
quality. — —
subthreshold-only
Connected mesh nodes evaluate alternative links only
if the existing uplink becomes a sub-threshold link.
NOTE: Starting with ArubaOS 3.4.1, if a mesh point
using the subthreshold-only mode reselects a more — —
