• Action — Defines the action attached to the class rule. The possible field

- Trust — Enables CoS-DSCP Trust Mode for the class. This command is
used to distinguish the QoS trust behavior for given traffic. When a given

received or default value and the relevant map, as defined on the QoS
Settings. By designating trust, it is possible to trust only incoming traffic
with certain DSCP values.
- Set — Defines the Trust configuration manually. The possible field
values are:
– DSCP — In the New Value box, the possible values are 0-63.
– CoS — In the New Value box, the possible values are 0-7.
NOTE The CoS setting will not affect regular IP traffic. This setting affects
only non-IP traffic, unless the outgoing port is Gigabit port.
• Police — Enables Policer functionality.
