Command History Release

Usage Guidelines The undebug sw-vlan ifs command is the same as the no debug sw-vlan ifs command.
When you enable debugging on a switch stack, 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.
When selecting the file read operation, Operation 1 reads the file header, which contains the header
verification word and the file version number. Operation 2 reads the main body of the file, which
contains most of the domain and VLAN information. Operation 3 reads type length version (TLV)
descriptor structures. Operation 4 reads TLV data.
