asxDS3LOSDetected
Module: Fore-Switch-MIB
OID (symbolic): Fore-Switch-MIB::asxDS3LOSDetected
OID (numeric): 1.3.6.1.4.1.326.2.2.0.120
Node type: NOTIFICATION-TYPE
Description: This trap indicates that the specified DS3 port has detected incoming LOS Alarm.
What is asxDS3LOSDetected?
This is a notification trap that is sent when a DS3 port on a Fore Switch ATM device detects a Loss of Signal (LOS) alarm condition on the incoming data stream. It indicates a critical physical layer failure where the DS3 signal is no longer present. An operator would receive this trap as an alert and would investigate the physical DS3 line, check cable connections, and verify carrier signal presence.
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> '' Fore-Switch-MIB::asxDS3LOSDetected snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.326.2.2.0.120
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:
