Chapter 9. SNMP Management

Table 9-2. Standard Trap

Index	Trap Names	Severity	Description
0	coldStart	NORMAL	the ATLAS is such that its configuration may be altered;
			this trap will be generated on power up
1	warmStart	NORMAL	the 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	authenticationFailur	Informational	the ATLAS has received a protocol message that has
	e		failed authentication

In RFC1213, or MIB II, the object type snmpEnabledAuthenTraps is defined. If you set this value to ‘2,’ the generation of the authenticationFailure trap is dis- abled. This trap is enabled by setting snmpEnableAuthenTraps to ‘1’. One possi- ble reason for an authentication failure would be an invalid community name in the received protocol message.

DS1 TRAPS

The ATLAS will support RFC1406, the DS1 standard MIB, as well as the ADT- RAN DS1 MIB, an extension to RFC1406. The ADTRAN DS1 groups provide the capability to send traps for DS1 Alarm failures and Performance Threshold Cross- ing Alerts. The DS1 Alarm Table, defined in the ADTRAN DS1 extension MIB, contains entries for enabling the status bits to send an Alarm Trap message. Each Alarm Table row entry corresponds to a DS1 interface managed by the device. The DS1 Alert Table, also defined in the ADTRAN DS1 MIB, contains similar entries for controlling the Alert Traps.

DS1 ALARM TRAPS

DS1 Line status is reported in the bit-encoded dsx1LineStatus object variable. Each trap represents a bit value = 1 change in dsx1LineStatus. Table 9-3 describes the DS1 Alarm Traps supported by the ATLAS.
