Command History
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 the TLV data errors during a file-read operation:
Switch# debug sw-vlan ifs read 4
vlan manager ifs read # 4 errors debugging is on
Switch#
open Enables the VLAN manager IFS debugging of errors in an IFS file-open operation.
read Debugs the errors that occurred when the IFS VLAN configuration file was open for
reading.
write Debugs the errors that occurred when the IFS VLAN configuration file was open for
writing.
{1 | 2 | 3 | 4} Determines the file-read operation. See the “Usage Guidelines” section for
information about operation levels.
write Debugs the errors that occurred during an IFS file-write operation.
