Dimension ES-3124 Ethernet Switch
Getting to Know the ES-3124 1-3
¾ Limit dynamic port MAC address learning ¾ Static MAC address filtering
Port Link Aggregation
The ES-3124 adheres to the 802.3ad standard for static and dynamic port link aggregation.
Bandwidth Control
¾ The ES-3124 supports rate limiting in 1Mbps increments allowing you to create different service plans.
¾ The ES-3124 supports IGMP snooping enabling group multicast traffic to be only forwarded to ports that
are members of that group; thus allowing you to significantly reduce multicast traffic passing through your
switch.
¾ Broadcast storm control
Quality of Service
¾ Eight queues so you can ensure mission-critical data gets delivered on time.
¾ Follows the IEEE 802.1p priority setting standard based on source/destination MAC addresses.
IGMP Snooping
The switch supports IGMP snooping enabling group multicast traffic to be only forwarded to ports that are
members of that group; thus allowing you to significantly reduce multicast traffic passing through your switch.
Multicast VLAN Registration (MVR)
Multicast VLAN Registration (MVR) is designed for applications (such as Media-on-Demand (MoD)) using
multicast traffic across a network. MVR allows one single multicast VLAN to be shared among different subscriber
VLANs on the network.
This improves bandwidth utilization by reducing multicast traffic in the subscriber VLANs and simplifies multicast
group management.
STP (Spanning Tree Protocol) / RSTP (Rapid STP)
(R)STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows
a switch to interact with other (R)STP-compliant switches in your network to ensure that only one path exists
between any two stations on the network.
Cluster Management
Cluster Management allows you to manage switches through one switch, called the cluster manager. The switches
must be directly connected and be in the same VLAN group so as to be able to communicate with one another using
same cluster management implementation.
1.2 Applications
This section shows a few examples of using the ES-3124 in various network environments.
