policy attributes, you must first select its name from the menu.
The traffic flow direction to which the policy is applied.
The DiffServ class or classes associated with the policy. The policy is applied to a packet when a class

Select this option to assign matching packets to a traffic queue. Use the Queue ID Value field to select
the queue to which the packets of this policy-class are assigned.
Select this option to drop packets that match the policy-class.
Select this option to mark all packets in a traffic stream with the specified Class of Service (CoS) queue
value. Use the Class of Service field to select the CoS value to mark in the priority field of the 802.1p
header (the only tag in a single tagged packet or the first or outer 802.1Q tag of a double VLAN tagged
packet). If the packet does not already contain this header, one is inserted.
Select this option to mark all packets in a traffic stream with the specified secondary CoS queue
number. Use the Class of Service field to select the CoS value to mark in the priority field of the 802.1p
header in the secondary (inner) 802.1Q tag of a double VLAN tagged packet. If the packet does not
already contain this header, one is inserted.
Select this option to mark all packets in the associated traffic stream with the specified IP DSCP value. Then,
use one of the following fields to configure the IP DSCP value to mark in packets that match the policy-class:

a keyword, you cannot configure an IP DSCP Value.
• IP DSCP Value The IP DSCP value.
Select this option to mark all packets in the associated traffic stream with the specified IP Precedence
value. Then, select the IP Precedence Value to mark in packets that match the policy-class.
Select this option to copy the traffic stream to a specified egress port (physical or LAG) without bypassing
normal packet forwarding. This can occur in addition to any marking or policing action. It may also be specified
along with a QoS queue assignment. Use the Interface menu to select the interface to which traffic is mirrored.
