Muthu,
These are the default NSAP addresses used for LANE
components on a LANE module. The '**' gets filled in by the
subinterface number you use for the particular LANE
component.
The point with these default addresses is to make it easier
for you: you don't _have to_ enter any NSAP addresses (or
parts of NSAP addresses). If ILMI is turned on, you
automatically get an NSAP prefix (the first 13 bytes) from
the ATM switch, and this default scheme fills in the last 7
bytes for you.
Do you _want_ to use a different address? I would recommend
against it. But if you have/want to, you can use the 'atm
nsap-address zzzz...' or 'atm esi-address zzzz....' command
on the subinterfaces where you don't want to use the default
NSAP addresses. If you do this, be aware that you may need
to hard-code 'atm route' entries in one or more ATM
switches.
HTH,
Scott
