ds1ExcessiveCrc4ErrorTrap
Module: RAD-MIB
OID (symbolic): RAD-MIB::ds1ExcessiveCrc4ErrorTrap
OID (numeric): 1.3.6.1.4.1.164.3.1.6.4.0.16
Node type: NOTIFICATION-TYPE
Description:
This trap indicates that the error rate detected on the CRC-4 bits at the user DS1 interface, is high.
What is ds1ExcessiveCrc4ErrorTrap?
This is a trap (alert) that fires when the error rate on CRC-4 bits at a DS1 user interface exceeds a threshold. CRC-4 errors indicate bit corruption during T1 transmission. An operator receives this alert to escalate line quality issues to the carrier or replace cabling.
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> '' RAD-MIB::ds1ExcessiveCrc4ErrorTrap snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.164.3.1.6.4.0.16
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
