    Time to start statistics collection.  | 
 
| 
    start-time date/time: yyyy-mm-ddThh:mm:ss  |

| 
    disk-space disk-space-number  | 
  
    Specify the amount of memory allocated for statistics (including rotated log files). The default value is 50MB.  | 
 
For example:
CLI (network-admin@switch) > port-cos-stats-settings-modify enable
To view the port CoS statistics collection settings, use the command:
CLI (network-admin@switch) > port-cos-stats-settings-show
