Okay...I didn't really word that question very well, and
overcomplicated it.  Basically, my question is, when you
set up a LEC/LES/BUS, you specify whether the ELAN is 802.3
or 802.5, along with an MTU (usually 1516 and 4544
respectively).  What is the significance of this setting as
far as a purely ATM switch?  Or, is that configuration
setting meaningful to the bridging device only?

Thanks,

Bryan
