How to set BITS data type in SNMPSET command?

Question

the MIB OID object have data type 'Bits':

object_OID
Composed Type: Bits
Base Type: BITS
Access: read-write
Kind: Scalar
SMI Type: OBJECT-TYPE
Value List: 
doc (0)
emta (1)
cpe (2)

From MIB description, default is DEFVAL { '00'h }. I want set value 2 (cpe). I tried to set the value with command

snmpset -v2c -c public 192.168.100.1  [object_OID] b 2

but got

Error in packet.
Reason: wrongValue (The set value is illegal or unsupported in some way)

tried also

snmpset -v2c -c public 192.168.100.1  [object_OID] i 2

again error

Error in packet.
Reason: wrongType (The set datatype does not match the data type the agent expects)

Snmpget against this object returns Hex-STRING: 00 What is proper format to set value 2 for BITS data type?

Answer 1

You're using the correct syntax to set a BITS value. I would hazard a guess that the agent implementation is faulty (i.e. the agent is not following the MIB definition).

Answer 2

A correct Syntax for Net-SNMP is:

snmpset -v2c -c public 192.168.100.1   $ObjectId   = 'emta cpe'
