SNMP Trap Receiver Rule Edit
Peername – Specifies the peername that the trap is expected to be received from. If an IP address is given, then the IP address of the incoming trap message is checked. If a host name is given and the incoming trap message contains a host that could be looked up (via DNS lookup), then the host name field is checked instead of IP address.
TrapOID – Specifies the Trap OID that is expected. Traps and Informs always contain a Trap OID identifying the trap or inform, along with additional varbinds with a data payload. The Trap OID must match the OID given here before action will be taken.
VarOID – Specifies the varbind OID to look for in the message if the Peername and Trap OID match.
Hint – Provides direction on how to interpret data in the event the value type is Octet String. All ASN data types are interpreted according to their type; however, Octet String will default to being interpreted as a character string unless this hint says otherwise, and the length is exactly 4 or 8 bytes (octets).
| Hint Label | Description |
|---|---|
| None | No special interpretation |
| Float | Treat 4-byte Octet String as RFC 6340 IEEE 754 32-bit floating point |
| Double | Treat 8-byte Octet String as RFC 6340 IEEE 754 64-bit floating point |
Fixed – Enter “Y” to specify that a fixed value should be placed in the local object when this trap is received, rather than try to derive a data value from the trap message. Enter “N” to parse data from the trap varbind to be placed in the local object.
FixedVal – The fixed value to be placed in the local object any time this trap is received, assuming the Fixed column indicates “Y”. This feature is most often used in conjunction with the Timeout feature.
Timeout – Integer number of seconds for trap receive timeout. Note that this is not a session timeout, it provides for an automatic reset of the local object value. If zero, then the timeout feature is disabled.
TimeoutVal – Specifies the fixed value that should be placed in the local object after the timeout period has expired. The typical scenario is that either the value gleaned from the trap message itself, or the fixed value, would be placed in the local object upon receiving the trap. Then ‘timeout’ period later, the timeout value is placed in the local object, replacing the trap value.
ResultObj – Specifies the local object where data retrieved from the varbind called out by VarOID will be placed (or fixed value will be placed) assuming the VarOID is found, and Peername and Trap OID match.
