Emulab FAQ: Hardware Setup: What does 'Too many links of type ethernet!' mean (and what do I do)?
If you get the following message:
*** No possible mapping for node0053 Too many links of type ethernet!
it means that you tried to create more duplex links on a node than there are physical ethernet cards. Typical testbed machines have 2-4 available network cards, and so that is all the duplex links you can create. To get around this limitation, you can use a lan (with some loss of isolation between the hosts) or you can use our 'multiplexed link' support. This feature allows you to multiplex virtual network links onto a single physical node/ethernet link using VLAN devices.
