Filtering (Disabling) Traps
You can disable trap generating events in three ways:
Standard Traps
Table 11-2 describes the standard traps supported by ATLAS.
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.
1. Disable Trap Transmission. From the terminal menu, select SNMP
and set Trap Transmission to DISABLED .
OR
2. Define trap thresholds to disable specific trap events. Refer to the
ATLAS MIB in System Event Logging on page A-1 for a description of
each trap event supported by the ATLAS.
For example, consider the coldStart trap, a system controller event. If
you defined for destination 0 a trap filtering threshold of Warning for
the system controller, the coldStart trap would not generate to that
destination because the coldStart trap severity level is defined as
Normal . (Recall that each trap event has a severity level: Disabled,
Informational, Normal, Warning, Minor, Major, and Critical .)
OR
3. Control certain traps through SNMP of specific MIB variables. These
variables are outlined in the remainder of this chapter.
Table 11-2. Standard Traps
Index Trap Name Severity Description
0 coldStart Normal ATLAS is such that its configuration may be
altered; this trap is generated on power up.
1 warmStart Normal ATLAS is reinitializing without altering its
configuration.
2 linkDown Warning One of the ATLAS communication links has
failed.
3 linkUp Normal One of the ATLAS communication links has
come up.
4 authenticationFailure Informational ATLAS has received a protocol message
that has failed authentication.
