QoS Setup
QoS (Quality of Service) is a quite important issue for network devices now
because there are so many different data are transferred in the network –
phone call, audio, video, web business, email, file transfer, web access and
so on. Different data types have different requests about delay, throughput
and reliability on packet transfer. The network
administrators should know about their network
applications and the requests for these applications.
Then they can configure this switch to meet these
requests. When congestion happens on some ports
of the switch, the QoS operation can transfer
packets with different priorities, different drop rates,
different bandwidth allocations for different requests of packets.
This switch supports 4 priority queues on each 10/100Mbps ports and 8
priority queues on gigabit port if your model has it. This switch also support
2 classes of drop rates with WRED (Weighted Random Early Detection) logic
that you can configure. You can configure the priority and drop rate for the
priority values in VLAN tag and ToS of IP packet. You can also configure the
priority and drop rate for TCP/UDP logical service ports. You can configure
the packet scheduling operation on each priority queue and the traffic rate
on each port with the QoS function of the switch.
This section is a description about the QoS setting of the switch.
You can follow the entry for QoS setting. [ Advanced Management ] ->
[ QoS ]. And here is the main menu of QoS setting.
Menu Description
Global Setting For general settings of the QoS functions in the switch
Logical Port Define the TCP/IP service logical ports operation –
enable/disable, transmit priority, drop rate.
VLAN Define the transmit priority and drop rate operation in
the switch for each priority value in VLAN tag.
