4.3.2
Resetting MIB variables
In the application the “clients list” is read out from an access point through the
“snScalanceWDevicesMAC” MIB variable.
The “OID number” of this “MIB variable” is called:
1.3.6.1.4.1.4196.1.1.4.100.2.6.5.1.3.x (see
)
For the “FB3” to be able to process this “OID number”, the “OID number” has to be
converted first.
Converting the “OID number”
The first two numbers are summarized according to the formula (x * 40)+y.
In this example x=
1
and y=
3
.
(
1
*40) +
3
= 43.
Converted into the hexadecimal numbering system this is “
2B
”.
Instead of the number combination “
4196
”, the value “
A0.64
” is transferred.
(The value “A0.64” is not based on a special conversion)
Instead of the number combination “
100
” the hexadecimal value “
64
” is transferred.
The remaining number combinations are accepted as specified.
OID number:
1.3
.6.1.4.1.
4196
.1.1.4.
100
.2.6.5.1.3.x
Processed OID number:
2B
.6.1.4.1.
A0.64
.1.1.4.
64
.2.6.5.1.3.x
In “DB20” this revised “OID number” is stored.
The “x” at the end of the “OID number” is used as the index for the place within the
“Clients list” (similar to the numbering in a table).
In the chapter below, the structure of the “DB20” with the stored
“MIB variables” is displayed.
