hdsl2ShdslnoNeighborPresent
Module: HDSL2-SHDSL-LINE-MIB
OID (symbolic): HDSL2-SHDSL-LINE-MIB::hdsl2ShdslnoNeighborPresent
OID (numeric): 1.3.6.1.2.1.10.48.0.15
Node type: NOTIFICATION-TYPE
Description: This notification indicates that the bit setting for noNeighborPresent in the hdsl2ShdslEndpointCurrStatus object for this endpoint has changed.
What is hdsl2ShdslnoNeighborPresent?
This SNMP notification is generated when the status of the 'No Neighbor Present' flag changes on an HDSL2 or SHDSL endpoint, indicating the link has lost synchronization with its far-end peer. Loss of neighbor presence means the line is no longer synchronized and the connection is not operational. An operator would respond to this alert by investigating line quality, checking cables, or rebooting the endpoint to restore synchronization.
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> '' HDSL2-SHDSL-LINE-MIB::hdsl2ShdslnoNeighborPresent snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.10.48.0.15
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]:55196->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (394175900) 45 days, 14:55:59.00 SNMPv2-MIB::snmpTrapOID.0 = OID: HDSL2-SHDSL-LINE-MIB::hdsl2ShdslnoNeighborPresent
SNMPv3 example:
snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' HDSL2-SHDSL-LINE-MIB::hdsl2ShdslnoNeighborPresent
