Using the Technician Interface to Configure and Run Packet Capture

B-45

Instructions: Set to 1 (capture) if you want Packet Capture to copy only the packets

containing the data that matches the string.

Set to 2 (trigger) if you want Packet Capture to terminate when it matches

data in a packet to the string. Packet Capture does not copy the packet

containing the match.

Set to 3 if you want Packet Capture to copy every packet on a circuit,

regardless of its contents.

Parameters: Offset

Packet Capture supports four Offset parameters. The MIB information is

as follows:

Default: None

Range: Limited to size of buffer.

Function: Sets the offset in bytes from the reference point into the packet. The byte

pointed to by the offset is the ﬁrst byte in the packet that will be checked

for a match.

Instructions: Refer to the media you are ﬁltering in the section “Media-Speciﬁ

Instructions and Examples” later in this appendix.

Note: You can conﬁgure a ﬁlter as a capture type or a trigger type, but not

both. If you conﬁgure two receive ﬁlters, one a capture ﬁlter and the other a

trigger ﬁlter, conﬁgure the trigger ﬁlter afterwards.
