Chapter 17 Traffic Shaping for FortiOS 5.0 : Troubleshooting traffic shaping : Shaper diagnose commands : TOS command
  
TOS command
Use the following command to list command to view information of the TOS lists and traffic.
diagnose system tos-based-priority
This example displays the priority value currently correlated with each possible TOS bit value. Priority values are displayed in order of their corresponding TOS bit values, which can range between 0 and 15, from lowest TOS bit value to highest.
For example, if you have not configured TOS-based priorities, the following appears...
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
...reflecting that all packets are currently using the same default priority, high (value 0).
If you have configured a TOS-based priority of low (value 2) for packets with a ToS bit value of 3, the following appears...
0 0 0 2 0 0 0 0 0 0 0 0 0 0 0 0
...reflecting that most packets are using the default priority value, except those with a ToS bit value of 3.
