Module: NBS-EFM-MIB

OID (symbolic): NBS-EFM-MIB::nbsEfmOamEventNotificationTx

OID (numeric): 1.3.6.1.4.1.629.300.1.3.1.1.17

Node type: OBJECT-TYPE

Description: A count of OAMPDUs passed to the OAM subordinate sublayer for transmission that contain the Event Notification code specified in Table 57-4. This counter is incremented when a OAM:MA_DATA.request service primitive is generated within the OAM sublayer with an OAM code indicating an Event Notification operation.

What is nbsEfmOamEventNotificationTx?

This OID counts OAMPDUs transmitted that carry the Event Notification code (Table 57-4), incrementing on each corresponding OAM:MA_DATA.request primitive. An admin watches this to see how often this device is reporting link-quality events (like errored-symbol or errored-frame conditions) to its peer.
