asxDS1CRCErrCleared
Module: Fore-Switch-MIB
OID (symbolic): Fore-Switch-MIB::asxDS1CRCErrCleared
OID (numeric): 1.3.6.1.4.1.326.2.2.0.181
Node type: NOTIFICATION-TYPE
Description: This trap indicates that the excessive CRC-6 Error failure identified by trap asxDS1CRCErrDetected has been cleared. A CRC-6 Parity Error failure is cleared when the CRC-6 Error defect is absent for 10 +/- 0.5 seconds.
What is asxDS1CRCErrCleared?
This SNMP notification (trap) is sent when a previously detected CRC-6 Parity Error failure on a DS1 interface has been cleared and the line has recovered. The CRC-6 error condition is considered cleared after 10 seconds (plus or minus 0.5 seconds) of continuous error-free operation, confirming that the transmission path is healthy again. Network operators use this trap to correlate clearing events with line repairs or maintenance activities, closing incident tickets and verifying that line quality has restored.
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::asxDS1CRCErrCleared snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.326.2.2.0.181
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:
