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.
