Nortel Networks 5399 and 8000 Access Switch SNMP MIB Reference
5-4 300861-C Rev. 00
Thresholds
The threshold values are user selectable and range from 0 to 65535. When the
MIB counter meets or exceeds the threshold value, the corresponding trap is sent
to the trap hosts. Setting the threshold value to 0 disables the corresponding error
trap while setting the threshold to a higher number reduces the network traffic.
