You can disable trap generating events in three ways:
1. Disable T T
RAP RANSMISSION
and set T T
RAP RANSMISSION
OR
2. Define trap thresholds to disable specific trap events. Refer to the
ATLAS 550 MIB in System Event Logging on page A-1 for a description
of each trap event supported by the ATLAS 550.
For example, consider the coldStart trap which is a system controller
event. If you defined for destination 0, a trap filtering threshold of
for the system controller, then the coldStart trap would not

generate to that destination because the coldStart trap severity level is
defined as N
ORMAL
(Recall that each trap event has a severity level: D
, N , W
TIONAL ORMAL
OR
3. Control certain traps through SNMP of specific MIB variables. These
variables are outlined in the remainder of this chapter.
RFC1213, or MIB II, defines the object type snmpEnabledAuthenTraps. If you
set this value to 2, the generation of the authenticationFailure trap is disabled.
This trap is enabled by setting snmpEnableAuthenTraps to 1. One possible rea-
son for an authentication failure would be an invalid community name in
the received protocol message. Table 13-1 describes the standard traps sup-
ported by ATLAS 550.

configuration.
