     3== Clearing Experiment Settings ==
     4
     5Before starting a wireless experiment, we want to restore the wireless environment to its default state. These commands are run from the console on Outdoor to
     6reset all of the base station and attenuation settings:
     7
     8{{{
     9wget -qO- "http://wimaxrf:5004/wimaxrf/bs/default"
     10wget -qO- "http://wimaxrf:5004/wimaxrf/bs/restart"
     11wget -qO- "http://wimaxrf:5004/wimaxrf/datapath/config/load?name=default"
     12}}}

     15== Loading a Saved Disk Image ==
     16
     17We're ready to load the previously prepared disk image onto a testbed node. We have separate images for the node that will act as a server, and the node that will act as a client.
     18
     19To load the image for Policy 1 onto the client node:
     20
     21{{{
     22omf load -i gec17_dash_policy_1.ndz -t node1-3.outdoor.orbit-lab.org
     23}}}
     24
     25>Note:
     26> We have implemented 3 different policies in the VLC source code and created a separate disk image for each.
     27> These are named {{{gec17_dash_policy_1.ndz}}}, {{{gec17_dash_policy_2.ndz}}}, and {{{gec17_dash_policy_3.ndz}}}
     28
     29
     30You can load the server image onto another node at the same time:
     31{{{
     32omf load -i gec17_dash_apache.ndz -t node1-5.outdoor.orbit-lab.org
     33}}}
     34
     35[[br]]
     36
     37> Tip: If any node doesn't seem to be checking in, e.g. you see output like this: [[br]]
     38> [[br]]
     39> {{{INFO stdlib: Waiting for nodes (Up/Down/Total): 2/1/3 - (still down: node1-5.outdoor.orbit-lab.org) [140 sec.]}}}  [[br]]
     40> [[br]]
     41> try opening another SSH session to the outdoor console and resetting the misbehaving node: [[br]]
     42> {{{omf tell -a reset -t node1-5.outdoor.orbit-lab.org}}} [[br]]
     43 [[br]]
