    1313When running uninstall the first thing it does is to move all control interfaces
    14 in all swapped in experiments to the common CONTROL vlan which takes under 20 seconds.

    1515Experimenters should be able to ssh to their nodes, which should have normal NFS

    1818It then performs some mop up operations which disable the traffic interfaces for
    1919both the ISI and Berkeley taggers, and removes all the other per-experiment control
    20 vlans.  The act of untagging the output traffic interface for each tagger is a snmpit

    2121corner case which will produce some diagnostics, but it actually does the correct thing
    2222and by that point should be irrelevant to the historic operation of the testbed.

    2626To enable control net separation, both commands are required.
    27 The separation process requires about 12 seconds for a normal swapped in experiment
    28 (independent of the number of the nodes in the experiment!) and will take about 30 seconds for a firewalled experiment.

    2929The site variable swap/lockout is set, and must be reset manually after the operator
