Usage Guidelines
The undebug sw-vlan ifs command is the same as the no debug sw-vlan ifs command.
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.
