Packet Capture Commands
P ACKET C APTURE C OMMANDS
In many applications, it is often desirable to monitor incoming LAN data. The pkt commands
will allow you to capture, display, save, and load bridged or routed data packets.
You must configure the terminal setting the same for Telnet and the terminal emulation package.
To do this, use the
term set command.
Note: Packet capture commands are available for both local and remote (Telnet) connections.
The following diagnostic packet commands are available:
pkt [on/off]
Enables or disables the Packet Capture feature.
pkt capture [all/idle/reqd/pend/actv/none]
Specifies which packets will be captured by the Packet Capture feature. A definition of each
possible parameter follows.
all
All packets will be captured.
none
No packets will be captured.
reqd
Only packets causing a connection to be requested will be captured.
pend
Only packets received while a requested connection is pending will be captured.
idle
Only packets not causing a connection to be requested will be captured. This could be
caused by the destination site not being in the Initiate Connection List, or by the route not
being in the IP Routing Table.
The pkt capture command allows multiple connection modes to be specified on a single
command line. For example, the command:
pkt capture reqd pend
captures only packets that cause a connection to be requested and packets that were received
before the connection became active.
pkt load <filename>
Loads previously saved Packet Capture file into memory.
pkt save <filename>
Saves captured packets to a disk file. Full path names are allowed, for example:
A:MYPKT.DAT.
