On the contrary, if you want to access the L2 portion of the IOS running on that switch, all you have to do is run this command:
switch#vlan database
switch(vlan)#?
VLAN database editing buffer manipulation commands:
abort Exit mode without applying the changes
apply Apply current changes and bump revision number
exit Apply changes, bump revision number, and exit mode
no Negate a command or set its defaults
reset Abandon current changes and reread current database
show Show database information
vlan Add, delete, or modify values associated with a single VLAN
vtp Perform VTP administrative functions.
Note the exit command, which takes you back to the regular prompt, at which you can run the show vtp status command.
The commands above were run on a Cat4006 with SupIII running IOS v.12.1(8a)EW1, which is the first and original IOS that the box shipped with. I don't believe that this has changed in newer releases of IOS for Cat.
