Chapter 11. SNMP Management

DS1 Traps

ATLAS supports RFC1406, the DS1 standard MIB, as well as the ADTRAN DS1 MIB, an extension to RFC1406. The ADTRAN DS1 group lets you send traps for DS1 Alarm Failures and Performance Threshold Crossing Alerts. The DS1 Alarm Table, defined in the ADTRAN DS1 extension MIB, contains entries that enable the status bits to send an Alarm Trap message. Each Alarm Table row entry corresponds to a DS1 interface managed by the de- vice. 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 11-3de-

scribes the DS1 alarm traps supported by ATLAS 810PLUS.

When enabled, ATLAS 810PLUS sends alarm traps to the each member of the trap destination list upon detecting status bit changes in dsx1LineStatus. Each status change sets an event bit = 1 in the adDS1LineEvent variable in the DS1 alarm table. If you have previously set the corresponding enable bit = 1 in the

adDS1LineArm variable and adDS1AlarmEnable = On, then ATLAS 810PLUS sends an alarm trap message. A single alarm trap message may report mul-

tiple event changes. ATLAS 810PLUS clears the event bits after sending the trap message or sending the response to a Get request for the adDS1LineEvent variable.

DS1 Alert Traps

RFC1406 also defines a series of Current and Total Alert threshold values.

You can enable ATLAS 810PLUS to send an alert trap message to each mem-
