Sorting
Session
Information
To
sort
the
information
shown
in
the
tables
by
a
particular
indicator,
click
the
column
label
by
which
you
want
to
order
things.
For
example,
if
you
want
to
see
the
table
rows
ordered
by
signal
strength,
click
the
Signal
column
label.
The
entries
will
be
sorted
by
signal
strength.
Configuring
and
Viewing
Channel
Management
Settings
When
Channel
Management
is
enabled,
the
UAP
automatically
assigns
radio
channels
used
by
clustered
access
points.
The
automatic
channel
assignment
reduces
mutual
interference
(or
interference
with
other
access
points
outside
of
its
cluster)
and
maximizes
Wi
‐
Fi
bandwidth
to
help
maintain
the
efficiency
of
communication
over
the
wireless
network.
You
must
start
channel
management
to
get
automatic
channel
assignments;
it
is
disabled
by
default
on
a
new
AP.
At
a
specified
interval,
the
Channel
Manager
maps
APs
to
channel
use
and
measures
interference
levels
in
the
cluster.
If
significant
channel
interference
is
detected,
the
Channel
Manager
automatically
re
‐
assigns
some
or
all
of
the
APs
to
new
channels
per
an
efficiency
algorithm
(or
automated
channel
plan
).
If
the
Channel
Manager
determines
that
a
change
is
necessary,
that
information
is
sent
to
all
members
of
the
cluster
and
a
syslog
message
is
generated
indicating
the
sender
AP,
new
and
old
channel
assignments.
The
Channel
Management
page
shows
previous,
current,
and
planned
channel
assignments
for
clustered
access
points.
By
default,
automatic
channel
assignment
is
disabled.
You
can
start
channel
management
to
optimize
channel
usage
across
the
cluster
on
a
scheduled
interval.
To
configure
and
view
the
channel
assignments
for
the
cluster
members,
click
the
Channel
Management
tab.
Rate
The
speed
at
which
this
access
point
is
transferring
data
to
the
specified
client.
The
data
transmission
rate
is
measured
in
megabits
per
second
(Mbps).
This
value
should
fall
within
the
range
of
the
advertised
rate
set
for
the
mode
in
use
on
the
access
point.
For
example,
6
to
54
Mbps
for
802.11a.
Signal
Indicates
the
strength
of
the
radio
frequency
(RF)
signal
the
client
receives
from
the
access
point.
The
measure
used
for
this
is
a
value
known
as
Received
Signal
Strength
Indication
(RSSI),
and
will
be
a
value
between
0
and
100.
RSSI
is
determined
by
a
mechanism
implemented
on
the
network
interface
card
(
NIC
)
of
the
client
station.
Rx
Total
Indicates
number
of
total
packets
received
by
the
client
during
the
current
session.
Tx
Total
Indicates
number
of
total
packets
transmitted
to
the
client
during
this
session.
Error
Rate
Indicates
the
percentage
of
time
frames
are
dropped
during
transmission
on
this
access
point.
