Chapter 2 Messages and Recovery Procedures
REDUNDANCY Messages
Error Message C4K_REDUNDANCY-2-SESSION_REGISTRY: Redundancy ISSU client failed to
register session information. Error: [dec] ([char])
Explanation
The Redundancy ISSU client failed to register session information. If a problem occurs
with the ISSU session registration, the standby device cannot be brought up properly.
Recommended Action Using the show issu compatibility matrix command, verify that both the
active and standby supervisor engines have software supporting ISSU. Reset the standby supervisor
engine using the redundancy reload peer command. If problems persist, contact a Cisco technical
support representative.
REDUNDANCY-3
Error Message C4K_REDUNDANCY-3-MSG_SIZE: Redundancy ISSU client failed to get the
MTU for Message Type [dec]. Error: [dec] ([char])
Explanation
The Redundancy ISSU client failed to calculate the MTU for the specified message. The
Redundancy ISSU client is not able to send the message to the standby device.
Recommended Action Using the show issu compatibility matrix command, verify that both the
active and standby supervisor engines have software supporting ISSU. Reset the standby supervisor
engine using the redundancy reload peer command. If problems persist, contact a Cisco technical
support representative.
Error Message C4K_REDUNDANCY-3-SESSION_UNREGISTRY: Redundancy ISSU client failed to
unregister session information. Error: [dec] ([char])
Explanation The redundancy ISSU client failed to unregister session information. This message
should only appear while the standby supervisor engine is reloading or if it has been physically
removed from the switch. If this message appears while the standby supervisor engine is in normal
operation, there may be a software problem but it will probably not affect redundancy functionality.
Recommended Action Check for existing ISSU sessions using the show issu session command, there
should not be any open sessions during a reload of the standby supervisor engine. Contact a Cisco
technical support representative if additional errors are seen after the standby supervisor engine
restarts and initializes.
Error Message C4K_REDUNDANCY-3-TRANSFORM_FAIL: Redundancy ISSU client [char]
transform failed for 'Message Type [dec]'. Error: [dec] ([char])
Explanation
The Redundancy ISSU client could not transform the specified message type. If the
transmit transformation failed, the checkpoint message was not sent to the standby device. If the
receive transformation failed, the checkpoint message was not applied on the standby device. In both
cases, the Redundancy state between the active device and the standby device is not identical.
Recommended Action Using the show issu compatibility matrix command, verify that both the
active and standby supervisor engines have software supporting ISSU. Reset the standby supervisor
engine using the redundancy reload peer command. If problems persist, contact a Cisco technical
support representative.
