vdslDownMaxSnrMgnNotification
Module: VDSL-LINE-MIB
OID (symbolic): VDSL-LINE-MIB::vdslDownMaxSnrMgnNotification
OID (numeric): 1.3.6.1.2.1.10.97.1.0.8
Node type: NOTIFICATION-TYPE
Description: The downstream Signal to Noise Margin exceeded vdslLineConfDownMaxSnrMgn. The object vdslPhysCurrSnrMgn will contain the Signal to Noise margin as measured by the VTU-R.
What is vdslDownMaxSnrMgnNotification?
This object represents an SNMP notification trap that is sent when the downstream Signal-to-Noise Ratio (SNR) margin exceeds a configured maximum threshold. The notification includes the actual SNR margin value as measured by the VDSL transceiver on the far end. Network operators use this alert to identify line degradation and potential service quality issues.
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> '' VDSL-LINE-MIB::vdslDownMaxSnrMgnNotification snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.10.97.1.0.8
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]:57678->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (157427534) 18 days, 5:17:55.34 SNMPv2-MIB::snmpTrapOID.0 = OID: VDSL-LINE-MIB::vdslDownMaxSnrMgnNotification

Create custom SNMP monitor using the VDSL-LINE-MIB::vdslDownMaxSnrMgnNotification OID value, configure state conditions and alerts, and monitor any vendor-neutral, standards-based MIB, DSLAMs and VDSL modems/transceivers (line coding/profile/transceiver-inventory status) from a single console.
