Using the Technician Interface to Configure and Run Packet Capture

B-43

Parameters: 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 ﬁlls.

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 ﬁlls,

set the Receive and Transmit Triggers to 1. If you select an option other

than 1 and the ﬁle ﬁlls, Packet Capture writes over the oldest packets in

the ﬁle.

If you want Packet Capture to terminate when it matches data to a string

you specify, use one of the following options:

• 2 to terminate when data matches the Filter 1 Match parameter

setting.

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 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 write over the oldest packets, regardless of whether an

interface received or transmitted them.
