Shown below is the shortcut LLC LEC, MPC VC established between the
ATM host’s MPC and the MPC on the remote MPOA-capable destination
system (or the edge device used to reach a legacy-LAN destination
system). You can identify the ATM host’s MPC selector (0x26), the
destination system’s ATM address
(47000580ffe1000000f21c4bea.0060b06e747a), and the destination
system’s MPC selector (0x36), which is shown at the end of the ATM
address. These three pieces of information are shown in bold in the
example below.

With a larger configuration, you would see many more MPOA VCs
created. For example, assuming that you have the following:
• Two VCs between each MPS and MPC.
• n MPOA-capable LAN Emulation interfaces on a specific card
instance.
• m targets on each interface (with a traffic volume large enough to be
considered an MPOA flow).
then, you should expect to see (2+ m )* n LLC LEC, MPC VCs created on that
particular card instance.
