** RFC1516 traps and HUBNVLE traps are issued under the same circumstances. Because of this, the hub issues traps
from one or the other MIB, but not both. The CPQN2FE MIB variable n2feTrapSupport lets you select which traps are
issued.
The following table describes when the 2824 hub issues each trap. The Health,
Group Change, and Reset traps are listed only once since they are issued under
the same circumstances.
Traps Issued
Trap Issued When
Cold Start Issued when the hub has completed a re-initialization
Authentication Failure Issued when the hub receives an SNMP request that is not properly authenticated;
usually this indicates an invalid community string
Rising Alarm Issued when a monitored MIB object exceeds a specified threshold. The RMON
alarmTable and eventTable must be appropriately configured to enable this trap.
Falling Alarm Issued when a monitored MIB object falls below a specified threshold. The RMON
alarmTable and eventTable must be appropriately configured to enable this trap.
Health Issued when changes occur in the 2824 hub operational state
Group Change Issued when a unit is added or removed from the stack. The RFC1516 trap provides
the unit number whose status changed. In the HUBNVLE trap, a 16-bit bitmap shows
which units are currently present in the stack; the least significant bit represents unit
1.
Reset Issued after completion of a reset initiated by rptrReset or rptrBasReset
