Whenever I've configured it with subinterfaces, SVC's and an NSAP
address I've had to set the 1 byte selector field to match the
subinterface number. If you got it to work with it set to .00 with the
same type scenario then perhaps I was doing something different from
your scenario.
Couple of Cisco references that may help as well:
http://www.cisco.com/en/US/partner/products/hw/switches/ps1893/products_
command_reference_chapter09186a008007dec5.html
"In the Cisco implementation of LANE, the prefix corresponds to the
switch, the ESI corresponds to the ATM interface, and the Selector field
corresponds to the specific subinterface of the interface."

Hello,
I kindly disagree with the last statement, I have implemented it with
.00
always, and have used subinterfaces and it has worked for me. What
happens
if you subinterface is atm 0.234, then you cant set the selector bit to
.234. Just my .02 cents.
Sincerely,
Matijevic
