SW_VLAN Messages
Error Message SW_VLAN-4-VTP_SEM_BUSY: VTP semaphore is unavailable for function
[chars]. Semaphore locked by [chars].
Explanation The VTP database is not available. You should access the VTP database later. The first
[chars] is the function name that you want to configure, and the second [chars] is the function name
that is using the VTP database.
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 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 1-7.
Error Message SW_VLAN-6-OLD_CONFIG_FILE_READ: Old version [dec] VLAN configuration
file detected and read OK. Version [dec] files will be written in the future.
Explanation The VLAN software detected an old version of the VLAN configuration file format. It
interpreted the file, but it will use the new format in the future. The first [dec] is the old version
number, and the second [dec] is the new version number.
Recommended Action No action is required.
Error Message SW_VLAN-6-VLAN_DAT_CACHE_EXISTS: Unexpected vlan.dat cache exists.
Removing the cache and continuing the sync with new set.
Explanation This message does not affect switch functionality.
Recommended Action No action is required.
Error Message SW_VLAN-3-VLAN_DAT_CACHE_SEQUENCE: Out of sequence vlan.dat sync
message. Expected: [dec]; received: [dec].
Explanation The vlan.dat file is synchronized to the STANDBY through one or more checkpoint
messages from ACTIVE. The sequence number for each set of checkpoint messages starts with 1.
These messages are cached at the STANDBY until the end-of-set indicator is received. The
STANDBY received a checkpoint message with a sequence number that does not match the expected
sequence number. The first [dec] is the expected checkpoint message sequence number, and the
second [dec] is the received checkpoint message sequence number.
Recommended Action Copy the message exactly as it appears on the console or in the system log.
