–
mirror transmits the classified traffic to the monitor port.
–
redirect transmits the classified traffic to the specified port.
– 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
– CoS marking marks the incoming frame on port with CoS values.
–
CoS remarking enables DSCP-based(L3 table) and Queue-based(L2 table)
packets filtering.
• Scheduling Algorithm
To handle traffic, you need to configure differently processing orders of traffic by using
scheduling algorithms. The switch provides:
– Strict Priority Queuing (SP)
–
Deficit Weighted Round Robin (DWRR).
An already applied rule can not 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 mul-
tiple policies. Otherwise, only one policer can belong to one policy.
The switch supports approximately 1000 rules which are actually running in the system as
many as policies.
