I've got an ATM network consisting of an 8510 switch at the central
site, connecting to about a dozen remote sites, most of which have
8510s and 3640 routers. All of the ATM configurations were done before
I started here, and I haven't really had much experience with ATM.

I've been asked to find a way to assign ports at the central site to a
particular vlan from each of the remote sites. The reason for this is
we're replacing servers at each of the remote sites, and it would be
much easier for the person setting them up to do all of the work at
the central site. From what I've seen, I understand that I'll need to
set up LANE. I've read the Cisco guide on LANE setup, and I'd like
someone to verify whether or not I'm on the right track. Here's what
I've got:

--------------
remote site
--------------

output of show lane default:

interface ATM0:
LANE Client: 39.840F8001BDE300001D450000.003085958002.**
LANE Server: 39.840F8001BDE300001D450000.003085958003.**
LANE Bus: 39.840F8001BDE300001D450000.003085958004.**
LANE Config Server: 39.840F8001BDE300001D450000.003085958005.00

config changes to remote site 3640 router:

atm lecs-address 39.840F8001BDE300001D450000.003085958005.00 1
lane database WOW_lane
name default server-atm-address
39.840F8001BDE300001D450000.003085958003.01
default-name default
interface atm0
lane server-bus ethernet default
lane config database WOW_lane
lane config auto-config-atm-address
interface atm0.2 multipoint [note: this subinterface already exists]
lane client ethernet 1 default

-------------
central site
-------------

output of show lane default:

interface ATM0:
LANE Client: 39.840F8001BDE300001D990000.003085A12D02.**
LANE Server: 39.840F8001BDE300001D990000.003085A12D03.**
LANE Bus: 39.840F8001BDE300001D990000.003085A12D04.**
LANE Config Server: 39.840F8001BDE300001D990000.003085A12D05.00

changes to the central site 8510 switch:

atm lecs-address 39.840F8001BDE300001D990000.003085A12D05.00 1
lane database ADM_lane
name default server-atm-address
39.840F8001BDE300001D990000.003085A12D03.01
default-name default
interface atm0
lane server-bus ethernet default
lane config database ADM_lane
lane config auto-config-atm-address
interface atm0.1
lane client ethernet 1 default

====================

questions:

- should these config changes work? The vlans in question wouldn't be
1, it would be more something like 945. Do I have to use the vlan
number in the config somewhere?
- in order to get this working to other remote sites, I would do them
the same way as the first remote site, and I wouldn't need any further
changes to the central site, correct?
- will this disrupt current operations to the remote site? This is a
production network.

Thank you!
