Attempting to create a new entry with a zero index fails silently.
root@localhost:/root> snmpset -v 2c -c NETMAN 10.0.2.15 .1.3.6.1.6.3.12.1.2.1.9.0.25 i 5
SNMP-TARGET-MIB::snmpTargetAddrRowStatus.'..' = INTEGER: createAndWait(5)
root@localhost:/root> snmpget -v 2c -c NETMAN 10.0.2.15 .1.3.6.1.6.3.12.1.2.1.9.0.25 i 5
snmp_build: unknown failuresnmpget: Error building ASN.1 representation (Can't build OID for variable)
Notice that there is no error when setting, only when trying to get.
A possibly workaround would be to escape the zero like this:
.1.3.6.1.6.3.12.1.2.1.9.\'0.25\'
$ configure --enable-board=common_pc --enable-kernel=standard --enable-rootfs=glibc_std
$ make fs
Copy the attached files to the correct locations in export/dist/
/etc/snmp/snmpd.conf
/etc/sysconfig/snmpd
Boot the target.
$ make start-target
On the target, fix ownership of the added files
# chown root:root /etc/snmp/snmpd.conf
# chown root:root /etc/sysconfig/snmpd
Start the server:
# /etc/init.d/snmpd start
Starting snmpd: [ OK ]
Verify the server is working
# snmpwalk -v 2c -c NETMAN 10.0.2.15 .1.3.6.1.6.3
SNMPv2-MIB::snmpSetSerialNo.0 = INTEGER: 1288531134

Add an entry (without a zero) to show working condition:
# snmpset -v 2c -c NETMAN 10.0.2.15 .1.3.6.1.6.3.12.1.2.1.9.116.101.115.116 i 5
SNMP-TARGET-MIB::snmpTargetAddrRowStatus.'test' = INTEGER: createAndWait(5)
# snmpget -v 2c -c NETMAN 10.0.2.15 .1.3.6.1.6.3.12.1.2.1.9.116.101.115.116
SNMP-TARGET-MIB::snmpTargetAddrRowStatus.'test' = INTEGER: notReady(3)
Now try with a zero, failing condition:
# snmpset -v 2c -c NETMAN 10.0.2.15 .1.3.6.1.6.3.12.1.2.1.9.0.25 i 5
SNMP-TARGET-MIB::snmpTargetAddrRowStatus.'..' = INTEGER: createAndWait(5)
# snmpget -v 2c -c NETMAN 10.0.2.15 .1.3.6.1.6.3.12.1.2.1.9.0.25 i 5
