Complete substeps c–f below for enabled clients.
Otherwise, go to substep a to select another client
or go to step 8 to exit the LEC ATM Adapter
configuration.
c Set the MTU Size.
This entry is used by the client to request an MTU
(Maximum Transfer Unit) size from the server. The
server, in turn, replies with an MTU equal to or
less than the requested value. All nodes that are
part of the same logical IP subnet must use the
same MTU size. Refer to your network
documentation to determine the appropriate
setting.
A setting of 1514 is recommended for ATM networks
that interface with an Ethernet LAN. If ATM nodes
are the only end-nodes on the network, a setting of
9K will dramatically improve performance.
d Enter the ELAN Name.
This is the network name of the server that you
prefer the client to join. Configuration servers,
such as the 3Com Cellplex 7000, require the
ELAN name of the LES you want the client to
join. Refer to your server documentation to
determine the specific requirements.
e Select the LECS/LES address option.
There are two radio buttons to set the type of
client contact at bootup.
■
LECS option: Contacts the LAN emulation
configuration server with the 20-byte address in
the ATM Address box. In turn, the LECS supplies
the client with all the necessary information to
contact the appropriate LAN emulation server
(LES).
