debug sw-vlan vtp
debug sw-vlan vtp
Use the debug sw-vlan vtp privileged EXEC command to enable debugging of the VLAN Trunking
Protocol (VTP) code. Use the no form of this command to disable debugging.
debug sw-vlan vtp {events | packets | pruning [packets | xmit] | redundancy | xmit}
no debug sw-vlan vtp {events | packets | pruning | redundancy | xmit}
Syntax Description
Defaults Debugging is disabled.
Command Modes Privileged EXEC
Command History
Usage Guidelines The undebug sw-vlan vtp command is the same as the no debug sw-vlan vtp command.
When you enable debugging, it is enabled only on the stack master. To enable debugging on a stack
member, you can start a session from the stack master by using the session switch-number privileged
EXEC command. Then enter the debug command at the command-line prompt of the stack member. You
also can use the remote command stack-member-number LINE privileged EXEC command on the stack
master switch to enable debugging on a member switch without first starting a session.
events Display debug messages for general-purpose logic flow and detailed VTP
messages generated by the VTP_LOG_RUNTIME macro in the VTP
code.
packets Display debug messages for the contents of all incoming VTP packets
that have been passed into the VTP code from the IOS VTP
platform-dependent layer, except for pruning packets.
pruning [packets | xmit] Display debug messages generated by the pruning segment of the VTP
code. The keywords have these meanings:
• packets—(Optional) Display debug messages for the contents of all
incoming VTP pruning packets that have been passed into the VTP
code from the IOS VTP platform-dependent layer.
• xmit—(Optional) Display debug messages for the contents of all
outgoing VTP packets that the VTP code requests the IOS VTP
platform-dependent layer to send.
redundancy Display debug messages for VTP redundancy.
xmit Display debug messages for the contents of all outgoing VTP packets that
the VTP code requests the IOS VTP platform-dependent layer to send,
except for pruning packets.
