Packet Capture Commands

PACKET CAPTURE COMMANDS

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.
