Capturing Packets

captured information to be stored and archived externally. Use these CLI commands
to send captured packets from APs to a hardware device or program. This command
is required to use Location Manager.
To Do this: Using this command:
Enter pcap mode and create a
packet capture profile.
packet-capture-profile either updates an existing
profile or creates a new profile and then enters pcap
mode where the rest of these commands are used.
Determine which APs will send
packets.
ap-list determines which APs will send packets. You
must type each AP name one by one, separated by
commas. At this time there is no all option or range
ability. This list is limited by buffer space; you can
enter 1, 2, 3,...90 without exceeding the limit. We rec-
ommend that you create the list in an application
such as Notepad and then paste it into the command
because if you exceed the buffer size, the command
fails and you have to retype the entire list of APs
again. If your list of APs exceeds the buffer size, you
can create another profile that covers the rest of the
APs.
Indicate packet destination.
Indicate which port to use.
mode sets the transmit mode to layer2 or layer3,
names the destination IP and names the port that
should be used. Port 9177 is used for Location Man-
ager and 17777 can be used for debugging.
Determine the biggest
packet size that you want an
AP to send.
packet-truncation-length sets packet capture trun-
cation length. Default is 0 for troubleshooting and
operation with WIPS. 82 is used for Location Man-
ager.
Decide if you want to limit the
rate at which packets are sent.
rate-limiting sets the packet capture rate limit to
per-station or cumulative.
! Note: Currently, if rate limiting is on, packets are
limited only for per-station.
Determine whether you want to
capture packets going to the
AP, coming from the AP, or
both. Only one option is avail-
able in System Director 5.1:
packets going to the AP.
rxtx sets traffic intrusion detection to received traffic,
sent traffic, or both. .
Limit bandwidth used. token-bucket-rate sets the token bucket rate.
