69 | | Ports 9 and 10 (and so on) are the ports that are connected to the dataplane interfaces on hosts (e.g. MyPLC, ProtoGENI, etc). Their key unusual feature is that they're trunk ports, i.e. they carry multiple tagged VLANs; this requires the hosts that you connect to them to speak 802.1q, aka "VLAN-based subinterfacing". Modern Linux distributions, like Ubuntu and Fedora / Red Hat, do this just fine fine, with interface names like eth1.1700, eth1.3715, etc. Configuring the hosts' dataplane interfaces to trunk ports is the key ingredient that allows experimenters to control which VLANs their compute slivers actually connect to. We're working on detailed guidelines for how campus resource operators can enable this on their hosts, and how experimenters can take advantage of it.
