VLAN and Voice VLAN
The EGS7228P provides support 802.1Q VLANs for improved convergence and
bandwidth utilization. The switch automates the process of setting up VoIP devices on
a network. Voice VLAN guarantees clear quality and efficient transmission for all voice
communications. VLANs also provide a means of securing each broadcast domain,
segregating them from each other. VLANs can be configured to segment departmental
resources. VLANs implemented on an SMB network help to restrict access to sensitive
information from one department to another.

Multicast Support
The EGS7228P supports IGMP Snooping, MLD Snooping, and VLAN for multicast
applications. By passively snooping IGMP packets transferred between the switch
and the IP multicast host, registration information is recorded and sorted into multicast
groups. The switch can then intelligently forward traffic to only those ports that
request multicast traffic. MLD Snooping enhances efficiency in selective distribution by
forwarding IPv6 multicast data to receiving ports, rather than flooding all ports in a VLAN.

IGMPv1—Defined in RFC 1112. An explicit join message is sent to the switch,
but a timeout is used to determine when hosts leave a group.
IGMPv2—Defined in RFC 2236. Adds an explicit leave message to the join
message so that the switch can more easily determine when a group has no
interested listeners on a LAN.
IGMPv3—Defined in RFC 3376. Support for a single source of content for a
multicast group.

QoS for Smoother Video Conferences and Clearer Phone Calls
Priority queueing ensures high-priority traffic gets delivered efficiently, even during
congestion from high traffic bursts. The ability to prioritize traffic ensures quality of
latency-sensitive services and applications despite increasing traffic loads. For mission
critical environments, the EGS7228P supports 802.1D, 802.1w and 802.1s Spanning
Tree Protocols (STP). STP allows you to configure the switch with a redundant backup
bridge path, so transmission and reception of packets can be guaranteed in the event
of any failed switch on the network. To help streamline networks, 802.1p Priority Tagging
places a priority tag in a specified frame placing it in a priority queue once received and
enabling it to be prioritized ahead of other frames. IEEE 802.1p enables administrators
to assign and designate traffic priority. This process helps applications such as VoIP and
video conferencing to be delivered clear and jitter-free.

Making the Network More Secure
The EGS7228P also supports 802.1X port-based authentication, so IT managers can
authenticate clients via external RADIUS servers. In addition, the Access Control List
(ACL) feature enhances network security and protects the network by screening traffic
from unauthorized MAC or IP addresses.

Energy Saving
This EnGenius Layer 2 Switch is capable of conserving power without sacrificing
operational performance. With the Energy Efficient Ethernet (EEE) standard, the network
will automatically decrease its power usage when traffic is low with no setup required.
The PoE Management feature lets IT managers control the PoE on each port so that
unnecessary power consumption can be saved during off hours. The switch can also
detect the length of connected cables to automatically reduce power usage on shorter
cable connections.

Power over Ethernet (PoE)
With a total power budget of 185 Watts for the EGS7228P, customers can choose to
plug in up to 24 802.3at/af IP-based devices. Power-over-Ethernet (PoE) optimizes the
installation and power management of network devices such as wireless Access Points
(APs), Voice over IP (VoIP) phones, and IP-based surveillance cameras. In addition,
the EGS7228P’s Power-over- Ethernet (IEEE 802.3at/af) capabilities reduce installation
time and costs for many new network productivity devices. Free your wireless AP
deployments and IP cameras from the restrictions of power outlet proximity using a
standard Cat 5 cable.
