Moxa E Series Managed Ethernet Switch Featured Functions
3-39
GMRP
GMRP is a MAC-based multicast management protocol, whereas IGMP is IP-based. GMRP provides a
mechanism that allows bridges and end stations to register or un-register Group membership information
dynamically.

Setting Description Factory Default
Select/Deselect Checkmark the check boxes to enable GMRP function for the
port listed in the Port column.
None
GMRP Status
The Moxa switch displays the current active GMRP groups that were detected.
MAC Address: The Multicast MAC address
Static Port: This multicast address is defined by static multicast
Learned Port: This multicast address is learned by GMRP
QoS
The Moxa 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 Moxa switch can inspect both IEEE 802.1p/1Q layer 2 CoS tags, and even
layer 3 TOS information to provide consistent classification of the entire network. The Moxa 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 managing congestion.
• Assign priorities to different categories of traffic. For example, set higher priorities for time-critical or
business-critical applications.
• Provide predictable throughput for multimedia applications, such as video conferencing or voice over IP,
and minimize traffic delay and jitter.
• Improve network performance as the amount of traffic grows. Doing so will reduce costs since it will not be
necessary to keep adding bandwidth to the network.
