Authentication Trap
Enables or disables the reporting of SNMP 
authentication failures. If enabled, a notifi-
cation trap is sent to the configured trap 
addresses in the event of an authentica-
tion failure. The default value is False.
BER
Bit Error Rate
Bit Error Rate
The probability that a transmitted bit will be 
erroneously received. The BER is 
measured by counting the number of bits 
in error at the output of a receiver and 
dividing by the total number of bits in the 
transmission. BER is typically expressed 
as a negative power of 10.
Buffer Credit
A measure of port buffer capacity equal to 
one frame.
Class 2 Service
A service that multiplexes frames at frame 
boundaries to or from one or more 
N_Ports wit h acknowledgment provided.
Class 3 Service
A service that multiplexes frames at frame 
boundaries to or from one or more 
N_Ports without acknowledgment.
Contact
Specifies the name of the contact person 
who is to be contacted to respond to trap 
events. The default is undefined.
Datagram
A message sent between two communi-
