tmnxEqPortEtherCrcAlarm
Module: TIMETRA-PORT-MIB
OID (symbolic): TIMETRA-PORT-MIB::tmnxEqPortEtherCrcAlarm
OID (numeric): 1.3.6.1.4.1.6527.3.1.3.2.2.0.52
Node type: NOTIFICATION-TYPE
Description:
tmnxEqPortEtherCrcAlarm is generated when an Ethernet port CRC alarm condition is detected. It is generated only when the type of alarm being raised is enabled on the port.
[EFFECT] On a signal failure (SF) fault, the port is taken out of service until the CRC alarm condition is cleared.
[RECOVERY] tmnxEqPortEtherCrcAlarm is cleared by taking the port out of service (eg. shutdown, card/mda reset, physical link loss), or changing/disabling the associated threshold/multiplier values.
Signal Degradation is self clearing and will clear once the error rate drops below 1/10th of the configured rate.
What is tmnxEqPortEtherCrcAlarm?
This is a network alarm notification that alerts operators when a port detects cyclic redundancy check (CRC) errors exceeding a configured threshold, indicating data corruption on the Ethernet link. The alarm is only generated if the specific CRC alarm type is enabled for the port and typically triggers when signal degradation or failure conditions occur. Once triggered, the port is removed from service and can be restored by clearing the alarm condition or disabling the associated monitoring thresholds.
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> '' TIMETRA-PORT-MIB::tmnxEqPortEtherCrcAlarm snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.6527.3.1.3.2.2.0.52
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
