Event name	apsEventChannelMismatch
SNMP notification prefix and OID	APS-MIB.apsNotificationsPrefix.3
Default severity	minor
Message format string	Channel Mismatch is declared

Application name	APS
Event ID	2005
Event name	apsEventFEPLF
SNMP notification prefix and OID	APS-MIB.apsNotificationsPrefix.5
Default severity	minor
Message format string	FEPL failure is declared
Cause	FEPLF (Far-End Protection Line Failure) notification is generated based on SF (Signal Failure) condition on the protection port in the received K1 Byte.
Effect	Traffic will switch (Tx/Rx) to the working port if the traffic is presently Tx-ed/Rx-ed to/from the protection port.

SNMP notification prefix and OID	APS-MIB.apsNotificationsPrefix.2
Default severity	minor
Message format string	Mode Mismatch is declared
Cause	Mode Mismatch notification is generated due to a conflict between the current local mode (switching direction or architecture) and the received K2 mode information.
Effect	For switching direction mismatch, the operational switching direction is changed to unidirectional. For switch architecture mismatch, the local end runs in 1+1 mode irrespective of the remote end switching architecture.
Recovery	Configure both local and remote end to run in same switching mode (direction/architecture).

SNMP notification prefix and OID	APS-MIB.apsNotificationsPrefix.1
Default severity	minor
Message format string	APS switchover from $subject$.
Cause	APS switchover between working port (channel 1) and protection port (channel 0) can happen due to change of status of any port or user-initiated switch commands on any port.
Effect	Traffic is transmitted to and received from the other channel/port.
Recovery	None.
