Cisco ME 3400E Ethernet Access Switch
Debug Commands


Please confirm whether or not the This appendix describes the debug privileged EXEC commands that have been created or changed for use with the Cisco ME 3400E Ethernet Access switch. These commands are helpful in diagnosing and resolving internetworking problems and should be enabled only under the guidance of Cisco technical support staff.


Caution Because debugging output is assigned high priority in the CPU process, it can render the system unusable. For this reason, use the debug commands only to troubleshoot specific problems or during troubleshooting sessions with Cisco technical support staff. It is best to use the debug commands during periods of lower network traffic and fewer users. Debugging during these periods decreases the likelihood that increased debug command processing overhead will affect system use.

Use the debug sw-vlan ifs privileged EXEC command to enable debugging of the VLAN manager IOS file system (IFS) error tests. Use the no form of this command to disable debugging.

debug sw-vlan ifs {open {read | write} | read {1 | 2 | 3 | 4} | write}

no debug sw-vlan ifs {open {read | write} | read {1 | 2 | 3 | 4} | write}

Syntax Description

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.


Defaults

Debugging is disabled.

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.
