Usage Guidelines The following are four types of file read operations:
• 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 TLV descriptor structures.
• Operation 4—Reads TLV data.
Examples This example shows how to debug of TLV data errors during a file-read operation:
Switch# debug sw-vlan ifs read 4
