Using the Technician Interface to Configure and Run Packet Capture

Trigger Parameters

You use triggers to stop copying packets when an event occurs. The trigger

parameters consist of a receive trigger and a transmit trigger. Each trigger stops

Packet Capture, regardless of whether it is copying packets received, transmitted,

or both. A description of the trigger parameters follows.

Parameter: Trigger

Packet Capture supports two trigger parameters. The MIB information is as

follows:

Default: 4 (Not used)

Options: 1 (Buffer full)

2 (Match Filter 1)

3 (Match Filter 2)

4 (Not used)

Function: Sets Packet Capture to terminate automatically when the packet data

matches a string that you specify or when the Packet Capture file is full.

The receive trigger parameter terminates Packet Capture if you set it to a

filter, and the incoming packet data matches a string that you specify.

The transmit trigger parameter terminates Packet Capture if you set it to a

filter, and the outgoing packet data matches a string that you specify.

Instructions: If you want Packet Capture to terminate when the Packet Capture file is

full, set the receive and transmit triggers to 1. If you select an option other

than 1 and the file is full, Packet Capture overwrites the oldest packets in

the file.

Outgoing wfPktCaptureTxTrigger 13 1.3.6.1.4.1.18.3.4.21.1.1.13

Caution:

If you configure Packet Capture to copy both incoming and

outgoing packets, it copies them to a single file. Therefore, if you choose both

packet directions, and you set one of these parameters (Receive Trigger or

Transmit Trigger) to 1, you must set the other parameter to 1. If you fail to do

this, Packet Capture may overwrite the oldest packets, regardless of whether an

interface received or transmitted them.
