Here is a runbook for the SNMP trap E5-121-TRAPS-MIB::cfmCcmError:
Meaning #
The cfmCcmError trap is generated when a Connectivity Fault Management (CFM) Continuity Check Message (CCM) error occurs on a particular interface. This trap indicates that there is an issue with the CFM protocol, which is used to detect and report network faults.
Impact #
The impact of this trap is that network faults may not be detected or reported accurately, leading to potential network outages or service disruptions. Additionally, this error may also indicate a configuration issue or a problem with the network device itself, which can affect network reliability and availability.
Diagnosis #
To diagnose the issue, the following steps can be taken:
- Check the interface configuration for CFM and ensure that it is enabled and configured correctly.
- Verify that the CCM packets are being sent and received correctly on the interface.
- Review the device logs for any error messages related to CFM or CCM.
- Use network diagnostic tools to verify the connectivity and integrity of the interface.
Mitigation #
To mitigate the issue, the following steps can be taken:
- Check and correct any configuration issues related to CFM and CCM on the interface.
- Restart the CFM protocol on the interface or restart the device if necessary.
- Verify that the CCM packets are being sent and received correctly on the interface after the restart.
- Consider implementing additional monitoring and diagnostic tools to detect and report network faults more effectively.
Variables #
intfCfmCcmErrorCause: This variable indicates the cause of the CFM CCM error. Possible values include incorrect configuration, packet corruption, or device hardware issues.
