SONET/SDH | 1013SONET TRAP ExampleSONET Traps on page 1015 describes the traps and OIDs for SONET alarms that are reported on anSNMP trap receiver. Figure 49-4 shows an example of a SONET trap.Figure 49-4. SONET Trap exampleSONET Syslog ExampleSyslog messages are generated for Critical, Major, and Minor alarm conditions detected on a SONETinterface according to the alarm hierarchy. For example, if a critical alarm condition is detected, a Syslogmessage is reported for the critical condition, but not for any major and minor alarms that may also befound. If a minor alarm condition is detected, a major or critical condition may also be reported.Figure 49-5 shows an example of the Syslog messages generated for SONET alarms:• Line Alarm Indication Signal (lais)• Path Remote Defect Indication (prdi)• Section Loss of Frame (slof)Figure 49-5. SONET Syslog Message examplesEvents that Bring Down a SONET InterfaceDown State configuration is supported on E-Series TeraScale et platforms.You can configure the SONET interface to change to a “down state” when certain SONET events arereported. When the event (or trigger) occurs, FTOS brings down the SONET interface. You can use thedelay triggers command to indicate a 100ms delay in bringing down the SONET interface once the eventor trigger is detected.2010-10-06 22:43:53 10.11.203.4 [10.11.203.4]:SNMPv2-MIB::sysUpTime.0 = Timeticks: (6057792) 16:49:37.92SNMPv2-MIB::snmpTrapOID.0 = OID:SNMPv2-SMI::enterprises.6027.3.3.2.2.0.18SNMPv2-SMI::enterprises.6027.3.3.1.2.1.1.3.0 = INTEGER: 10SNMPv2-SMI::enterprises.6027.3.3.1.2.1.1.2.0 = INTEGER: 518SNMPv2-SMI::enterprises.6027.3.3.1.2.1.1.4.0 = Counter32: 470351931SNMPv2-SMI::enterprises.6027.3.3.1.2.1.1.5.0 = INTEGER: 13SNMPv2-SMI::enterprises.6027.3.3.1.2.1.1.6.0 = INTEGER: 1SNMPv2-SMI::enterprises.6027.3.3.1.2.1.1.7.0 = STRING: "SNMP_SONET_Alarm: Interface Te 13/1 is out ofalarm PRDI"OID for Path Remote Defect Indication trapOct 6 04:46:51: %EXW4PF:13 %SONETAGT-5-ALARM: Interface Te 13/1 is out of alarm LAISOct 6 04:46:42: %EXW4PF:13 %SONETAGT-6-ALARM: Interface Te 13/1 is out of alarm PRDIOct 6 04:46:44: %EXW4PF:13 %SONETAGT-4-ALARM: Interface Te 13/1 is in alarm SLOF
