Hi ,
I have encountered some problems when dissecting the packets for a
protocol.I am mentioning 3 different scenarios
1.
In the below case , the octet is split into parts and each part viz x ,
y and z take different values.
I am not able to understand how to go about it.
PARAMETER 1
7
6
5
4
3
2
1
0
octet
X
Y
Z

Number of Digits

Digit 2
Digit 1

Digit 4
Digit 3

Digit 2n
Digit 2n-1

SUB PARAMETER X

bbb
SUB PARAMETER Y

2.
In the parameter mentioned below the value may come in a range,. How
can we dissect such values??
PARAMETER 2
Value
Description
0
1-10
10-255

In the following parameter, the value of each bit indicates if the
assosiated version is currently used or not.
Value 0 : not used
Value 1 : used
PARAMETER 3
Bit7
Bit6
Bit5
Bit4
Bit3
Bit2
Bit1
Bit0
octet
Is it possible to include such informations, which depend upon whether a
bit is set or not , in the dissector .
