SCHED Messages
Error Message SCHED-3-UNEXPECTEDEVENT: [traceback] [process information] Process
received unknown event (maj [hex], min [hex])
Explanation
An event was not processed. The first [hex] is the major event number, and the second
[hex] is the minor event number.
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. Use the Bug Toolkit to
look for similar reported problems. If you still need assistance, open a case with the TAC, or provide
your Cisco technical support representative with your information. For more information about these
online tools and about contacting Cisco, see the “Error Message Traceback Reports” section on
page 1-5.
SPANTREE Messages
Error Message SPANTREE-2-BLOCK_BPDUGUARD_VP: Received BPDU on port [chars], vlan
[dec] with BPDU Guard enabled. Disabling vlan.
Explanation
ABridge Protocol Data Unit (BPDU) was received on an interface and a VLAN . The
spanning tree BPDU guard feature was enabled and configured to shut down the VLAN. The VLAN
was placed in the error-disabled state. [chars] is the interface, and [dec] is the VLAN.
Recommended Action Either remove the device sending BPDUs or disable the BPDU guard feature.
You can configure the BPDU guard feature either locally on the interface or globally on all ports
enabled with Port Fast. Enter the clear errdisable privileged EXEC command to re-enable the
interface and VLAN.
Error Message SPANTREE-2-BLOCK_PVID_LOCAL: Blocking [chars] on [chars]. Inconsistent
local vlan.
Explanation
The spanning-tree port associated with the listed spanning-tree instance and interface
will be held in the spanning-tree blocking state until the port VLAN ID (PVID) inconsistency is
resolved. The listed spanning-tree instance is that of the native VLAN ID of the listed interface. The
first [chars] is the interface, and the second [chars] is the spanning-tree instance.
Recommended Action Verify that the configuration of the native VLAN ID is consistent on the
interfaces on each end of the 802.1Q trunk connection. When corrected, spanning tree automatically
unblocks the interfaces, as appropriate.
