You can quickly filter MAC addresses by entering one of the following criteria into the Search field.
Learnt Unicast Show all learnt Unicast MAC addresses.
Static Show all Static, Static Lock, and Static Multicast MAC addresses.
Multicast Show all Static Multicast MAC addresses.
Port x Show all MAC addresses associated with a specific port.
The table displays the following information:
VLAN ID This field shows the VLAN ID.
MAC Address This field shows the MAC address.
Type This field shows the type of this MAC address.
Port This field shows the port that this MAC address belongs to.
QoS
This section describes how Quality of Service (QoS) works and how to configure the relevant settings. There
are three main functions in this section:
CoS Mapping , DSCP Mapping , and Port Classification .
QoS Overview
The switch’s traffic prioritization capability provides Quality of Service (QoS) to your network by making
data delivery more reliable. You can prioritize traffic on your network to ensure that high priority data is
transmitted with minimum delay. Traffic can be controlled by a set of rules to obtain the required Quality of
Service for your network. The rules define different types of traffic and specify how each type should be
treated as it passes through the switch. The switch can inspect both IEEE 802.1p/1Q Layer 2 CoS (Class of
Service) tags, and even Layer 3 DSCP (Differentiated Services Code Point) information to provide consistent
classification of the entire network. The switch’s QoS capability improves the performance and determinism
of industrial networks for mission-critical applications.
The Traffic Prioritization Concept
Traffic prioritization allows you to prioritize data so that time-sensitive and system-critical data can be
transferred smoothly and with minimal delay over a network. The benefits of using traffic prioritization are:
• Improve network performance by controlling a wide variety of traffic and by managing congestion.
• Assign priorities to different categories of traffic. For example, set higher priorities for time-critical or
mission-critical applications.
•
Provide predictable throughput for multimedia applications, such as video conferencing or voice over IP,
and minimize traffic delay and jitter.
• Optimize the network utilization depending on application usage and usage needs. Hence, asset owners
do not always need to expand their backbone bandwidth as the amount of traffic increases.
Traffic prioritization uses eight traffic queues to ensure that higher priority traffic can be forwarded
separately from lower priority traffic, which guarantees Quality of Service (QoS) to your network.
Moxa switch traffic prioritization is based on two standards:
•
IEEE 802.1p —a Layer 2 QoS marking scheme
•
Differentiated Services (DiffServ) —a Layer 3 QoS marking scheme.
