Packet
Capture
Configuration
and
Settings
Wireless
packet
capture
operates
in
two
modes:
• Capture
file
mode
• Remote
capture
mode
For
capture
file
mode,
captured
packets
are
stored
in
a
file
on
the
Access
Point.
The
AP
can
transfer
the
file
to
a
TFTP
server.
The
file
is
formatted
in
pcap
format
and
can
be
examined
using
tools
such
as
Wireshark
and
OmniPeek.
For
remote
capture
mode,
the
captured
packets
are
redirected
in
real
time
to
an
external
PC
running
the
Wireshark®
tool.
The
AP
can
capture
the
following
types
of
packets:
• 802.11
packets
received
and
transmitted
on
radio
interfaces.
Packets
captured
on
radio
interfaces
include
the

such
