asxJ2AtmLCDDetected
Module: Fore-Switch-MIB
OID (symbolic): Fore-Switch-MIB::asxJ2AtmLCDDetected
OID (numeric): 1.3.6.1.4.1.326.2.2.0.230
Node type: NOTIFICATION-TYPE
Description: This trap indicates that the specified J2 port is experiencing Loss of Cell Deliniation (LCD). A LCD failure is declared when the LCD defect persists for a period of 2.5 +/- 0.5 seconds.
What is asxJ2AtmLCDDetected?
This trap indicates that an ATM J2 port is experiencing Loss of Cell Delineation (LCD), a condition where the port cannot synchronize with the incoming ATM cell stream and identify cell boundaries. A LCD failure is declared after the defect persists for 2.5 seconds, indicating a serious link-layer problem. Network operators use this trap to immediately alert them to ATM link degradation requiring urgent investigation and potential circuit rerouting.
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::asxJ2AtmLCDDetected snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.326.2.2.0.230
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:
