EEPROM Access Mask:
It is used to specify areas where EEPROM is not rewritten to indices below
set values from network.
[EPUSE = 1000: MIB system group]
When EPUSE is set to 1000 (MIB system group), the EEPROM user area is interpreted as follows:
Offset
Area size (byte)
Usage
28h to 3Bh
40
Character string that becomes sysDescr of MIB-II system group.
3Ch to 3Fh
8
OID that becomes sysObjectID of MIB-II system group.
Store sysDescr in the form of character string. To store it as “test,” for example, store the following value from
the offset 28h.
Byte string:
0
×74, 0×65, 0×73, 0×74
EEPROM:
0
×6574, 0×7473
When the byte string includes 0 or comes to 40 bytes, sysDescr is regarded to end there.
Store sysObjectID from below enterprise. Before storing it, encode it to OID type with BER. When the
sysObjectID is 1.3.6.1.4.1.1248.5.1.1.1, for example, store the following value from the offset 3Ch.
Byte string:
0
×89, 0×60, 0×05, 0×01, 0×01, 0×01
EEPROM:
0
×6089, 0×0105, 0×0101
When the byte string includes 0 or comes to 8 bytes, sysObjectID is regarded to end there.
Your attention is
requested to the fact that, if 1 stands at the most significant bit of the offset 3Fh, the data becomes abnormal.
