| 1.3.6.1.3.37.2.0.9 | isisAuthenticationTypeFailure | 
 | A notification sent when we receive a PDU with the wrong authentication type field. This notification includes the header of the packet, which may help a network manager identify the source of the confusion. This should be an edge-triggered notification. We should not send a second notification about PDUs received from what seem to be the same source. | This object is implemented as defined in the corresponding MIB files. |
