Easy Network Management and Visibility
This EnGenius Layer 2 Switch is designed for easy network management and can
quickly be added to an existing rack of other branded L2 and L3 switches. Configuring
the switch is made through an intuitive and user-friendly Web interface for quick and
easy management. The EnGenius L2 switch also includes SNMP (v1, v2 and v3) to
collect and track data to monitor network health, manage devices, and more easily
enforce critical IT controls and policies. The switch’s Link Layer Discovery Protocol
(LLDP) feature allows it and other network devices connected to it to announce and
display their identity and capabilities on the local network, which helps IT managers
better manage, troubleshoot or correct issues that may arise on the network.

VLAN and Voice VLAN
The EGS7252FP provides 802.1Q VLAN support 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 EGS7252FP 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 EGS7252FP 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 EGS7252FP 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.
