Troubleshooting LAN Emulation
For LAN Emulation, there are two possible cases you might need to
troubleshoot:
• ATM-connected-to-ATM-connected, where both end-systems (LECs)
are directly connected to an ATM switch. This is the case for systems
A and B in Figure 9-9 below.
• ATM-connected-to-legacy-LAN-connected,where one ATMconnected
end-system communicates with an end-system on a legacy LAN. This
is the case when systems A and B are in communication with system
C in Figure 9-9 below.
