Command History
Usage Guidelines The undebug sw-vlan ifs command is the same as the no debug sw-vlan ifs command.
When you enable debugging, 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.
open {read | write} Display VLAN manager IFS file-open operation debug messages. The
keywords have these meanings:
• read—Display VLAN manager IFS file-read operation debug messages.
• write—Display VLAN manager IFS file-write operation debug messages.
read {1 | 2 | 3 | 4} Display file-read operation debug messages for the specified error test (1, 2, 3,
or 4).
write Display file-write operation debug messages.
