IP
Address/Hostname
The
IP
address
or
hostname
of
the
sFlow
receiver.
Both
IPv4
and
IPv6
addresses
are
supported.
UDP
Port
The
UDP
port
on
which
the
sFlow
receiver
listens
to
sFlow
datagrams.
If
set
to
0
(zero),
the
default
port
(6343)
is
used.
Timeout
The
number
of
seconds
remaining
before
sampling
stops
and
the
current
sFlow
owner
is
released.
While
active,
the
current
time
left
can
be
updated
with
a
click
on
the
Refresh

button.
If
locally
managed,
the
timeout
can
be
changed
on
the
fly
without
affecting
any
other
settings.
Max.
Datagram
Size
The
maximum
number
of
data
bytes
that
can
be
sent
in
a
single
sample
datagram.
This
should
be
set
to
a
value
that
avoids
fragmentation
of
the
sFlow
datagrams.
Valid
range
is
200
to
1468
bytes
with
default
being
1400
bytes.
Port
Configuration
Port
The
port
number
for
which
the
configuration
below
applies.
Flow
Sampler
Enabled
Enables/disables
flow
sampling
on
this
port.
Flow
Sampler
Sampling
Rate
The
statistical
sampling
rate
for
packet
sampling.
Set
to
N
to
sample
on
average
1/Nth
of
the
packets
transmitted/received
on
the
port.
Not
all
sampling
rates
are
achievable.
If
an
unsupported
sampling
rate
is
requested,
the
switch
will
automatically
adjust
it
to
the
closest
achievable.
This
will
be
reported
back
in
this
field.
Flow
Sampler
Max.
Header
The
maximum
number
of
bytes
that
should
be
copied
from
a
sampled
packet
to
the
sFlow
datagram.
Valid
range
is
14
to
200
bytes
with
default
being
128
bytes.
If
the
maximum
datagram
size
does
not
take
into
account
the
maximum
header
size,
samples
may
be
dropped.
Counter

Enables/disables
counter
