Using the Technician Interface to Configure and Run Packet Capture

B-55

An example of a hexadecimal display of an ISDN frame follows:

Pkt# 1 11/02/94 16:04:06.151 LAPD 26 Tx

00000000: 00 ad 00 00 08 01 01 05 a1 04 02 88 90 18 01 83

00000010: 70 08 80 32 32 34 30 33 38 37

Interpreting a Packet Capture Instance Number

When you create an instance of Packet Capture, you refer to the MIB to get the

numeric identiﬁer, called a line number, of the datapath channel. You then copy

the line number when creating the Packet Capture instance. The instructions are in

“Cr

eating an Instance of Packet Capture” earlier in this appendix.

Site Manager automatically creates the line numbers when you use it to create a

conﬁguration ﬁle. A line number is a 10-digit, decimal number that is unique for

each datapath channel in a router. T

able B-2 shows the structure of a line number

or Packet Capture instance number. The top row in the table is for the most

signiﬁcant digit and the bottom row is for the least signiﬁcant digits. An example

follows.
