– permit allows traffic matching given characteristics.
– deny blocks traffic matching given characteristics.
– copy-to-cpu duplicates the profile of classified packets and sends a copy to CPU
packets filtering.
• Scheduling Algorithm
To handle traffic, you need to configure differently processing orders of traffic by using
scheduling algorithms. The V5808 provides:
– Strict Priority Queuing (SP)
– Deficit Round Robin (DRR)
– Weighted Round Robin (WRR)
An already applied rule cannot be modified. It needs to be deleted and then created again
with changed values.
Weight can be used to additionally adjust the scheduling mode per queue in DWRR
mode. Weight controls the scheduling precedence of the internal packet queues.

Fig. 7.2 Structure of Rule
You can simply manage more than 2 Flows through one Class. Flow or Class and Policer
can be implemented by one policy.
Both Flow and Class cannot belong to one policy together. It means that one policy can
include only one either Flow or Class. However, a single flow or class can belong to
multiple policies. Otherwise, only one policer can belong to one policy.
7.5.2 Packet Classification
Packet classification features allow traffic to be partitioned into multiple priority levels, or
classes of service. In Flow Configuration mode, you can set packet classification criterias
