    2324  * '''$ ps -elf | grep oml2-server'''

    3031Before the experiment, the BS parameters can be changed. The following are a few examples commands to control the MCS:[[BR]]
     32* To set the BS parameters back to defaults:
     33  * '''$ wget -O status http://cons-wm-01:5052/wimaxrf/defaults'''
     34
    3135* To get the current MCS:
    32   * '''$ wget -O status http://localhost:5052/wimaxrf/mcsProfile'''
     36  * '''$ wget -O status http://cons-wm-01:5052/wimaxrf/mcsProfile'''
    3337
    3438* Change downlink MCS to single profile:
    35   * '''$ wget -O status http://localhost:5052/wimaxrf/mcsProfile?dl=15 '''
     39  * '''$ wget -O status http://cons-wm-01:5052/wimaxrf/mcsProfile?dl=15 '''
    3640
    3741* Change downlink MCS with profile list:
    38   * '''$ wget -O status http://localhost:5052/wimaxrf/mcsProfile?dl=15,17,18'''
     42  * '''$ wget -O status http://cons-wm-01:5052/wimaxrf/mcsProfile?dl=15,17,18'''
    3943
    4044* Change uplink MCS to single profile:
    41   * '''$ wget -O status http://localhost:5052/wimaxrf/mcsProfile?ul=15'''
     45  * '''$ wget -O status http://cons-wm-01:5052/wimaxrf/mcsProfile?ul=15'''
    4246
    4347* Change uplink MCS with profile list:
    44   * '''$ wget -O status http://localhost:5052/wimaxrf/mcsProfile?ul=15,17,18'''
    45 
    46 * To restart the base station:
    47   * '''$ wget http://localhost:5052/wimaxrf/restart'''
    48 
     48  * '''$ wget -O status http://cons-wm-01:5052/wimaxrf/mcsProfile?ul=15,17,18'''
     49
     50* To restart the base station: 
     51  * '''$ wget http://cons-wm-01:5052/wimaxrf/restart'''
     52Please note: After issuing a restart the BS will need 2 minutes before accepting connection requests. [[BR]]

    318322== Trouble shooting & miscellaneous info ==
     323After running the experiment, if the dependent variables (ie. kBperS) are all 0, then it's most likely the Wimax BS needs to be configured properly. Please try the following:
     324  * Set the BS back to default configuration.[[BR]]
     325  * Set the RF attenuator matrix to 0 dB attenuation. Please refer to ''RF Matrix Control Services'' under http://wimax.orbit-lab.org/wiki for more details on changing attenuator values. Many times the attenuator values is set to the maximum (63 dB) in which case the nodes will not be able to with the BS.
