We have modified the standard link down trap configuration to assert a custom event and alarm. This works except for the Cisco models. The Cisco models still assert the default out of the box events and alarms.
Out of the box, the standard mib-2 link down trap is defined in the $SPECROOT/SS/CsVendor/IETF/AlertMap as follows:
2.0 0x00220001 22.214.171.124.126.96.36.199.1.1(1,2)\
As you can see above, the out of the box event is 0x00220001.
We have modified the AlertMap file to assert a custom event like the following example::
2.0 0xfff00001 188.8.131.52.184.108.40.206.1.1(1,2)\
When the link down trap is received for a non-Cisco model, the 0xfff00001 event is asserted. However, when the link down trap is received for a Cisco model, the 0x00220001 event is still asserted.
