REDUNDANCY Messages
REDUNDANCY-2
Error Message C4K_REDUNDANCY-2-HANDSHAKE_TIMEOUT_ACTIVE: The handshake messaging
between active and standby has not yet started.
Explanation
The initial handshake message exchange between active and standby supervisor engines
has not yet started. Traffic on the active supervisor engine is not affected, but supervisor engine
redundancy will not work.
Recommended Action Please schedule a downtime ASAP and reset the active supervisor engine.
Error Message C4K_REDUNDANCY-2-HANDSHAKE_TIMEOUT_STANDBY: The handshake messaging
between standby and active has not yet started.
Explanation
The initial handshake message exchange between standby and active supervisor engines
has not yet started. If the active supervisor engine has not completed its initialization, this message
may be seen temporarily on the standby supervisor engine. This condition will correct itself once
the active supervisor engine initialization is complete. If problems persist after the active supervisor
engine is initialized then redundancy will not work.
Recommended Action Please schedule a downtime ASAP and reset the active supervisor engine.
Error Message C4K_REDUNDANCY-2-POSTFAIL_RESET:POST failure on ACTIVE supervisor
detected. [char]
Explanation The active supervisor engine failed POST but detected the standby supervisor engine at
bootup. It is attempting to reset itself so that the standby supervisor engine can take over as the new
active supervisor engine.
Recommended Action You may need to replace the supervisor engine that failed POST. Contact your
technical support representative.
Error Message C4K_REDUNDANCY-2-INCOMPATIBLE_SUPERVISORS: [char]
Explanation
For proper operation of redundancy, the supervisor engines must be of the same model.
In this condition redundancy operations are not available and the standby supervisor engine is
disabled because the supervisor engines present are of different models.
Recommended Action Configure the hardware so that the active and standby supervisor engines are
of the same model.
Error Message C4K_REDUNDANCY-2-IOS_VERSION_CHECK_FAIL: [char]
Explanation
The active and standby supervisor engine software is different. In this condition,
redundancy operations are not guaranteed.
Recommended Action Configure the active and standby supervisor engines to use the same version of
software.
