Another merit for WRR algorithm: Though the queues are scheduled by turn, they are
not configured with fixed time quantum. If a queue has no packets, the system
immediately schedules the next queue. Then bandwidth resources can be fully utilized.
VIII. Traffic mirroring
Traffic mirroring duplicates specified packets to CPU for network test and
troubleshooting.
IX. Port mirroring
Port mirroring duplicates all packets at a specified port to the monitoring port for
network test and troubleshooting.
X. Flow-based traffic statistics
The system can make traffic statistics based on flow for further analysis.
33.2 Introduction to Port Group-Based QoS Configuration To configure QACL for a port group on the Switch 8800, you only need to create a port
group and configure QACL for the group. Then the configuration becomes valid for all
members in the group. This group-based QACL configuration saves you from
configuring QACL for individual ports. After this configuration, the QACL configuration
of each member port remains consistent forever.
33.2.1 Group-Based QoS Configuration Task
The following table describes the group-based QoS configuration tasks. (Suppose the
flow template and ACL are defined already.)
