Before configure your device over SNMP, you need to enable read-write and limit the access with an ACL.
snmp-server community <your_community> RW <Access-list>
Now you can configured your device with snmp-set command. The following example show how upload a new configuration on your running-config with a TFTP Server.
snmpset -v <version> -c <community> <your_router> \ .1.3.6.1.4.1.9.9.96.1.1.1.1.3.50 i 1 \ .1.3.6.1.4.1.9.9.96.1.1.1.1.4.50 i 4 \ .1.3.6.1.4.1.9.9.96.1.1.1.1.5.50 a "<IP TFTP Server>" \ .1.3.6.1.4.1.9.9.96.1.1.1.1.6.50 s "<filename>" \ .1.3.6.1.4.1.9.9.96.1.1.1.1.14.50 i 4
