alarmLoopbackError

OID (symbolic): ADVA-FSPR7-MIB::alarmLoopbackError

OID (numeric): 1.3.6.1.4.1.2544.1.11.7.5.0.189

Node type: NOTIFICATION-TYPE

Description:

A loop in the PPP-IP path is detected

What is alarmLoopbackError?

This SNMP trap (notification) is issued when the ADVA FSP R7 optical system detects a loop in the PPP-IP protocol stack path. A loop indicates packets are circulating back to their source, creating a serious connectivity fault requiring immediate investigation. Network operators treat this trap as a critical alert to identify and eliminate the layer 3 routing misconfiguration.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' ADVA-FSPR7-MIB::alarmLoopbackError
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.2544.1.11.7.5.0.189

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:57288->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (121959880) 14 days, 2:46:38.80
  SNMPv2-MIB::snmpTrapOID.0 = OID: ADVA-FSPR7-MIB::alarmLoopbackError

SNMPv3 example:

snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' ADVA-FSPR7-MIB::alarmLoopbackError
