Using the Technician Interface to Configure and Run Packet Capture

B-51

Frame Relay Switch and SMDS Switch

The Frame Relay Switch and SMDS Switch work the same way as described in

the “F

rame Relay” and “SMDS” sections.

LAPB

The LAPB (Link Access Procedure-Balanced) protocol currently does not have a

special data link ﬁlter offset. If you conﬁgure a data link ﬁlter, set the offset to 0.

The data link ﬁlter works the same way that the MAC ﬁlter works.

An example of a hexadecimal display of a LAPB packet follows:

Pkt# 7 07/20/95 14:22:17.820 LAPB 5 Rx

00000000: 03 64 10 01 81

Passthru

The Passthru (PASS) protocol currently does not have a special data link ﬁlter

offset. If you conﬁgure a data link ﬁlter, set the offset to 0. The data link ﬁlter

works the same way that the MAC ﬁlter works.

An example of a hexadecimal display of a Passthru packet follows:

Pkt# 9 04/26/94 09:00:50.730 PASS 24 Tx

00000000: 07 03 00 00 a2 02 c9 b6 00 00 a2 02 c9 b6 81 02

00000010: 01 01 00 00 00 00 00 2a 00 00 00 00 00 00 00 00

PPP

The PPP (point-to-point; Standard Protocol) protocol currently does not have a

special data link ﬁlter offset. If you conﬁgure a data link ﬁlter, set the offset to 0.

The data link ﬁlter works the same way that the MAC ﬁlter works.

An example of a hexadecimal display of a PPP packet follows:

Pkt# 9 04/18/94 12:58:45.551 PPP 39 Rx

00000000: ff 03 02 01 00 00 00 00 00 80 00 00 00 a3 00 00

00000010: 0c 00 00 00 00 80 00 00 00 a3 00 00 0c 80 02 00

00000020: 00 14 00 02 00 0f 00 1d 00 00 00 00 00 00 00 00
