Joel,
I trie it very long time back and not able to recollect exact steps now.But
as far as I remember VTP can be enabled on LANE also.Once VTP is enabled on
LANE ,I think I observed it by creating a new VLAN in CAT5K <working in VTP
server mode> and checked for new elan in LANE and the same VLAN in other
switch.
This is also explained in CCO.
Only restruction is the default Vlan and ELAN should have the name itself as
default.Otherwise this was not working.
Correct me if I am wrong.If I find time I will try it again and let U know.

Sorry, but both are wrong. The only way an ELAN is created is by definition
in the LECS database. It is impossible to exist otherwise. VLANs are
defined on either a VTP Server or VTP Transparent switch, VTP will propagate
the VLAN information to other VTP Servers and VTP Clients only.
When you create a LEC on the catalyst you must 'map' a VLAN of your choice
to the ELAN. The numbers do NOT have to match, but often do for ease of
understanding. The names can also be unrelated.
Example follows:
lane config database <dB name>
name <ELAN Name> server-atm-address <NSAP> ! this creates the ELAN
interface atm 0
atm pvc 1 0 5 qsaal ! mandatory sig
nalling
atm pvc 2 0 16 ilmi ! mandatory sig
naling
lane config database <dB name> ! this starts t
he LECS
lane config auto-config-atm-address ! this identifi
es the NSAP to use
interface atm 0.1 multipoint
lane server-bus ethernet <ELAN Name> ! this creates
the LES and BUS
simultaneously
lane client ethernet <VLAN> <ELAN Name> ! this creates
the LEC & maps
the VLAN to ELAN
All this is done in the LANE module of the Catalyst.
set vtp domain <name> ! initializes V
TP (default type is Server)
set vlan <VLAN Number> ! creates the VLAN call
ed VLAN0001
All this is done on the supervisor of the Catalyst. There are options in
the set vlan command, but if you are doing Ethernet, you can accept the
defaults.
Only caveat: the ATM subinterface number in decimal must match the Selector
Byte value of the LES in hex.
VTP has no knowledge of LANE and doesn't care about ELANS. The LECS &
LES-BUS have no knowledge of VTP and doesn't care about VLANs. That is why
you must map them together with the lane client command.
