Figure 34-18. User-Created Attribute
Once you have created the attribute and recorded its number, you can create an e-mail referring to
it with the following:
{[Label]:[number]}
For example:
{UserDefined:1282301548078}
NOTE:
You can select the created attribute, and copy the label and number with Ctrl+C. You must delete
extraneous text when you paste it, but copying and pasting simplifies creating such notifications.
Best practice is to clarify such attributes by combining them with others that spell out their source.
Trap Forwarding Process
SNMPv1 and SNMPv3 traps become SNMPv2 Traps
SNMPv1 traps are converted according to RFC 1908. SNMPv3 traps are already in SNMPv2 format
and the application simply does not use SNMPv3 security when sending these northbound. The
following is the relevant snippet from RFC 1908:
3.1.2. SNMPv1 -> SNMPv2
When converting responses received from a SNMPv1 entity acting in an agent role into
responses sent to a SNMPv2 entity acting in a manager role:
(1) ...
(2) If a Trap-PDU is received, then it is mapped into a SNMPv2-Trap-PDU. This is done by
prepending onto the variable-bindings field two new bindings: sysUpTime.0 [6], which takes
its value from the timestamp field of the Trap-PDU; and, snmpTrapOID.0 [6], which is
