Setting Verification
Only the device, with MAC address "FC:4D:D4:F8:71:CF", connected to port 3 of the switch
can access the higher-level network. The device with MAC address "FC:4D:D4:F8:71:CF"
connected to other ports of the switch cannot access the higher-level network.
8.2 QoS
8.2.1 Overview
Traditional IP network mainly involves business, like www, FTP, E-mail, etc. It can deliver
packets to the destination but ensures no guarantee of forwarding delay, jitter, packet loss
rate and reliability.
As IP technology develops rapidly and all kinds of new business, such as distance
education, teleconference, VOD, etc. emerge, IP network has turned into a multi-service
bearer network from a pure data network. Thus, QoS appears.
Briefly speaking, QoS provides network applications with different quality of service, like
provide dedicated bandwidth, decrease transmission delay and jitter, reduce packet loss
rate, etc.
How QoS works
This switch provides the simple QoS function. By setting a port priority, the system first
discard packets on low-priority ports during network congestion to ensure transmission of
packets on high-priority ports. The switch has a total of two priority queues. Queue Low is of
low priority. Queue High is of high priority. The scheduling algorithms supported by the
switch are First in First Out (FIFO), Strict Priority (SP), and Weighted Round Robin (WRR).
By default, the scheduling algorithm is FIFO.
Queue Scheduling Algorithms
1. FIFO
FIFO is that packets that are received first are forwarded first. It applies to most network
