The "type" parameter must be one of the following, depending on the type of variable to set on the SNMP host:
u unsigned INTEGER
x HEX STRING
d DECIMAL STRING
If OPAQUE_SPECIAL_TYPES was defined while compiling the SNMP library, the
following are also valid:
U unsigned int64
I signed int64
As an example, using "i" would set an integer, and "s" would set a string. If the SNMP host rejects the data type, you might get the following message: "Warning: Error in packet. Reason: (badValue) The value given has the wrong type or length."
If you specify an unknown or invalid OID, you might get a "Could not add variable" message. When specifying an absolute OID (one that is already resolved) that is completely numeric, prepend it with a period. For example, an OID that could enable/disable Ethernet ports on an Asante hub might be "126.96.36.199.188.8.131.52.184.108.40.206.6.4.0", but you would need to use ".220.127.116.11.18.104.22.168.22.214.171.124.6.4.0" in the OID parameter so that the SNMP library won't try to resolve an already resolved OID. Friendly, unresolved OIDs do not need the period prepended, such as "system.SysContact.0"
