Don't hope to hijack this thread but I have a question very much along the same lines as the initial question. Actually, have been attempting to use the information here to help with turning off an ERN notification.
Platform: Mitel 3300 MXe II version 4
ERN Trap shows all the same OIDs as in the example Wireshark capture. When attempting to gather information on currently set values for the OIDs shown in the trap I get nothing as if the OID doesn't exist. For example, get-request on OID 1.3.1.6.1.1027.4.1.1.3.4.0 after a test emergency call shows no value.
Attempting to retrieve current value of 1.3.1.6.1.4.11027.4.1.1.3.9.1.2.1 also shows no value. In fact if I walk the MIB 1.3.1.6.1.4.1.1027.4, none of the MIBs shown in the actual trap coming from the switch are available. Is it because these values are not readable and can only be set? Such that setting the OID 1.3.6.1.4.1.1027.4.1.1.3.9.1.2.1 to an integer value of 1 will stop the traps from continuing for the default period of 2.5 hours (or something along those lines) unless acknowledged?
