    3636Assuming the MyPLC plnodes are all up and running, here are the commands that Josh has been using to test inter-campus connections. ('shmux' is a utility for running a command on multiple remote hosts, and aggregating the output)

    38 Set $net and $slicename to control which slice and network you want to test:
     38For any of these tests, set $net and $slicename to control which slice and subnet you want to test:

    4343}}}
    4444
    45 Test everything:
     45These tests rely on ping having a non-zero exit status when it gets a 100% failure rate. It's not clear from the man page what the exit status is when ''some'' packets are received.
     46
     47These tests will produce some failures for slices that don't include every campus, of course. plastic-101 and plastic-102 include every campus; the former uses VLAN 3715 and the latter VLAN 3716, so they're likely candidates for basic connectivity testing.

     51This tests only that each of the BBN MyPLC plnode can reach the others on a subnet, which is a useful way to tell if anything at all is working on that subnet.

     59Each of these lines tries to ping every known IP address on the subnet, from each of the MyPLC plnodes at one of the sites.
