4. Verify that a connection has been made to the LAN Emulation server (LES).
A LAN Emulation client must establish and maintain a connection to the LES. In
most cases, the LES also establishes and maintains a second connection to the client.
Find the LES addressin the output of lanestat, and then look for connections with
that address as the destination or source in the output of qccstat.
Ifyou do not see any connections with that address, take the appropriate action from
the list below:
■If you have a LAN Emulation configuration server (LECS):
Make sure that the correct address is configuredfor the LECS. By default, the
SunATMsoftware uses the ATM Forum well-known address. If your LECS uses a
different address, enter the alternate addressin the /etc/opt/SUNWconn/atm/
laneconfig file. See “Editing the laneconfig File” on page53 for information on
editing /etc/opt/SUNWconn/atm/laneconfig. Youcan check the address
currently being used in the output of lanestat.
■If you do not have an LECS:
One of the LECS functions is to providethe LES address, so if you do not have an
LECS, you must provide the address. Create anentry in /etc/opt/SUNWconn/
atm/laneconfig. See “Editing the laneconfig File” on page53. You can check
the LES address currently being used in the output of lanestat.
■Verifythat the LECS, if present, and LES are configured properly.
5. Verify that a connection has been made to the BUS.
Inaddition to the LES connection(s), a LAN Emulation client must also establish and
maintain a connection to the BUS, and the BUS typically establishes and maintains a
second connection to the client. Youcan find the BUS ATM address in the output of
lanestat, and then verify that there is a connection with that address as the
destination, and probably a second connection with that address as source, in the
output of qccstat. If there are no connections, verify that the BUS is configured
properly.
6. Verify that the host has joined the Emulated LAN.
The lanestate field in the output of lanestat indicates that the client is in the
active state.
If your system cannot join the emulated LAN, there may be a problemwith the way
in which your LAN Emulation services areconfigured. If the Emulated LAN uses an
MTUsize larger than 9 Kbytes, the SunATM host will not join (9 Kbytes is the largest
MTU size supported by the SunATMproduct). If the host is not able to join, an error
message will be printed with an explanation.
