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 inf
ormation 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 t
he ELAN. The numbers do NOT have to match, but often do for ease of understand
ing. 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 s
et 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 Byt
e 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 ma
p them together with the lane client command.
