Error Message PM-4-ERR_DISABLE: [chars] error detected on [chars], putting [chars]
in err-disable state.
Explanation The port manager detected a misconfiguration or misbehavior and placed the interface
in an error-disabled state. A recovery is attempted after the configured retry time (the default is 5
minutes). On PoE switches, this message might appear when a device that can be powered by either
a PoE switch port or by AC power is not being powered by an external AC power source and is
connected to a port that has been configured with the power inline never interface configuration
command. [chars] is the port where the threshold was exceeded. The first [chars] is the error, and
the second and third [chars] are the affected interfaces.
Recommended Action On non-PoE switches, copy the message exactly as it appears on the console or
in the system log. Research and attempt to resolve the error by using the Output Interpreter. Enter
the show tech-support user EXEC command to gather data that might help identify the nature of
the error. Use the Bug Toolkit to look for similar reported problems. On PoE switches, remove the
device or configure the port by entering the power inline auto, shutdown, and no shutdown
interface configuration commands. If you still require assistance, open a case with the TAC, or
contact your Cisco technical support representative, and provide the representative with the gathered
information. For more information about these online tools and about contacting Cisco, see the
“Error
Message Traceback Reports” section on page 2-7.
Error Message PM-4-ERR_DISABLE_VP: [chars] error detected on [chars], vlan [dec].
Putting in err-disable state.
Explanation This is a defensive measure that puts the virtual port (that is, the port-VLAN pair) in an
error-disabled state when it detects a misconfiguration or misbehavior. If configured, a recovery will
be attempted after the configured retry time (default time is 5 minutes). The first [chars] is the error,
and the second [chars] is the port.
Recommended Action Copy the message exactly as it appears on the console or in the system log.
Research and attempt to resolve the error using the Output Interpreter. Use the Bug Toolkit to look
for similar reported problems. If you still require assistance, open a case with the TA C, or contact
your Cisco technical support representative, and provide the representative with the gathered
information. For more information about these online tools and about contacting Cisco, see the
“Error
Message Traceback Reports” section on page 2-7.
Error Message PM-4-ERR_RECOVER: Attempting to recover from [chars] err-disable state
on [chars].
Explanation The port manager is attempting to bring the interface up after taking it down to the
error-disabled state. The first [chars] is the error, and the second [chars] is the affected interface.
Recommended Action Copy the message exactly as it appears on the console or in the system log.
Research and attempt to resolve the error by using the Output Interpreter. Enter the show
tech-support user EXEC command to gather data that might help identify the nature of the error.
Use the Bug Toolkit to look for similar reported problems. If you still require assistance, open a case
with the TAC, or contact your Cisco technical support representative, and provide the representative
with the gathered information. For more information about these online tools and about contacting
