Benefits
QoS with four priority queues
The QoS(Quality Of Service) Control List (QCL) feature provides four
internal queues to support four different classifications of traffic. High
priority packet streams experience less delay inside the switch, which
supports lower latency for certain delay-sensitive traffic. The
FGS-2924R/RD can classify the packet as one of the four priorities
according to vip port, 802.1p priority tag, DiffServ. The QoS operates at
full wire speed. The actual scheduling can be based upon a strict
priority, weighted round robin.
Port Mirroring
This mechanism helps track network errors or abnormal packet
transmission without interrupting the flow of data. Allow ingress traffic
to be monitored by a single port that is defined as mirror capture port.
The mirror capture port can be any 10/100 port, 10/100/1000 port.
Mirroring multiple ports is possible but can create congestion at the
mirror capture port.
Q-in-Q VLAN for performance & security
The Q-in-Q (Double-Tag) VLAN feature in the switch offers the benefits
of both security and performance. VLAN is used to isolate traffic
between different users and thus provides better security. Limiting the
broadcast traffic to within the same VLAN broadcast domain also
enhances performance and use of double VLAN tags.
Isolated Group, provides protection for certain ports
The isolated group feature allows certain ports to be designated as
protected. All other ports are non-isolated. Traffic between isolated
group members is blocked. Traffic can only be sent from isolated group
to non-isolated group.
Mac-based 802.3ad LACP with automatic link fail-over
Dynamic fail-over means packets will not get assigned to any trunk
member port that has failed. If one of the ports were to fail, traffic will
automatically get distributed to the remaining active ports.
802.1X Access Control improves network security
802.1x features enable user authentication for each network access
attempt. Port security features allow you to limit the number of MAC
addresses per port in order to control the number of stations for each
port. Static MAC addresses can be defined for each port to ensure only
registered machines are allowed to access. By enabling both of these
features, you can establish an access mechanism based on user and
machine identities, as well as control the number of access stations.
802.1D Compatible, 802.1w Rapid Spanning Tree and 802.1s
Multiple Spanning Tree
For mission critical environments with multiple switches supporting
STP, you can configure the switches with a redundant backup bridge
path, so transmission and reception of packets can be guaranteed in
event of any fail-over switch on the network.

Overview
FGS-2924R/RD, a 24-port Gigabit L2 Plus
Managed Switch, is a standard switch that
meets all IEEE 802.3/u/x/z Gigabit, Fast
Ethernet specifications. The switch includes
16-Port Gigabit SFP and 8-Port Combo
Gigabit TP/SFP Fiber dual media
management Ethernet switch. The switch
can be managed through RS-232 serial port,
or through Ethernet port using CLI or Webbased management unit, associated with
SNMP agent.
With the SNMP agent, the network
administrator can logon the switch to
monitor, configure and control each port's
activity in a friendly way. The overall
network management is enhanced and the
network efficiency is also improved to
accommodate high bandwidth applications.
In addition, the switch features
comprehensive and useful functions such
as DHCP Snooping (includes Option 82),
QoS (Quality of Service), Spanning Tree/
Rapid Spanning Tree/ Multiple Spanning
Tree, VLAN, Port Trunking, Bandwidth
Control, Advanced Security(IP-MAC-Port
Binding, ACLs, SSL/SSH, TACACS+,
802.1x), MVR,SNMP/RMON, LLDP and
IGMPv3 Snooping capability via the
intelligent software. It is suitable for both
metro-LAN and office applications.
Others the switch increase support the
Power saving for reduce the power
consumption with Power Management
technique. It could efficient saving the
switch power with auto detect the client
idle and cable length to provide different
power. The serial products have two kinds
model with FGS-2924R (AC Power Input)
and FGS-2924RD (DC Power Input)
MSTP is according to IEEE 802.1Q 2005 Clause 13 Multiple Spanning
Tree Protocol. MSTP allows frames assigned to different VLANs to
follow separate paths, each based on an independent Multiple
Spanning Tree Instance (MSTI), within Multiple Spanning Tree (MST)
Regions composed of LANs and or MST Bridges.
DHCP Snooping (Including DHCP Option 82)
This DHCP Snooping enables the Dynamic Host Configuration
Protocol (DHCP) relay agent information (option 82) was included in
the feature. To include information about itself and the attached client
when forwarding DHCP requests from a DHCP client to a DHCP server
via Trust Port. The DHCP server can use this information to assign IP
addresses gateway subnet mask DNS for each subscriber of a
service-provider network. The DHCP Snooping is using Trust Port and
Trust DHCP Server IP Address to filter the illegal DHCP server traffic.
IGMPv3 Snooping
By default, layer 2 Ethernet switches treat IP multicast traffic in the
same manner as broadcast traffic namely, by forwarding frames
received on one interface to all other interfaces. This may create
excessive traffic on the network and degrade the performance of hosts
attached to the switches. The IGMPv3 snooping can significantly
reduce traffic from streaming media and other bandwidth-intensive IP
multicast applications.
IGMP Proxy
The IGMP proxy and IGMPv3 Snooping is the same functional target,
but mechanism has some thing different as below:
---IGMP Proxy can send v1/v2 IGMP query together.
---IGMP Proxy supports General Query Mac Response Timeout for
checking the "client alive status" and speed up the convergence of
multicast group member.
---IGMP Proxy provides Specific (Last member) Query to check (can be
multiple times) whether other members interest in the same multicast
group exist when the port receives IGMP leave.
---IGMP Proxy checks (can be multiple times) the latest status of the
group member by scheduled polling from General/Specific Query. It
avoids instant port link-down that makes the members to be removed
from multicast group.
The IGMP Proxy is providing better performance than IGMPv3
Snooping for IGMP join and leave message exchange in the switch.
8 dual media ports for flexible fiber connection
8-Port dual media ports are provided for flexible fiber connection. You
can select to install optional transceiver modules in these slots for
short, medium or long distance fiber backbone attachment. Use of the
SFP will disable their corresponding built-in 10/100/1000Base-T
connections.
Broadcast/Multicast/Unknown-Unicast Storm Control
To limit too many broadcast/multicast/unknown-unicast flooding in the
network, broadcast/multicast storm control is used to restrict excess
traffic. Threshold values are available to control the rate limit for each
port. Packets are discarded if the count exceeds the configured upper
threshold.
MVR
Multicast VLAN Registration (MVR) can support carrier to serve
content provider using multicast for Video streaming application in the
network. Each content provider Video streaming has a dedicated
multicast VLAN. The MVR routes packets received in a multicast
source VLAN to one or more receive VLANs. Clients are in the receive
VLANs and the multicast server is in the source VLAN.
IP-MAC-Port Binding
The IP network layer uses a four-byte address. The Ethernet link layer
uses a six-byte MAC address. Binding these two address types to
gether allows the transmission of data between the layers. The primary
purpose of IP-MAC binding is to restrict the access to a switch to a

number of authorized users. Only the authorized client can access the Switch's port by checking the pair of IPMAC Addresses and port number with the pre-configured database. If an unauthorized user tries to access an IP
-MAC binding enabled port, the system will block the access by dropping its packet.
Access Control List (ACL)
The ACLs are divided into EtherTypes. IPv4, ARP protocol, MAC and VLAN parameters etc. Here we will just go
over the standard and extended access lists for TCP/IP. As you create ACEs for ingress classification, you can
assign a policy for each port, the policy number is 1-8, however, each policy can be applied to any port. This makes
it very easy to determine what type of ACL policy you will be working with.
Support Two RADIUS Authentication Server
The switch supports the RADIUS authentication for secure switch port security. It provides more secure
authentication for management. The switch can assign two RADIUS server for redundant authentication server
requirement.
SSL and SSH for secure Managemen(Optional by Project requirement)
Secure Sockets Layer (SSL) supports the encryption for all HTTP traffic, allowing secure access to the browserbased management GUI in the switch. And Secure Shell (SSH) which supports the encryption for all transmitted
data for secure, remote command-line interface (CLI) access over IP networks
Support Two TACACS+ for Management Authentication(Optional by Project requirement)
The switch supports the TACACS+ authentication for secure switch CLI Logon. It provides more secure
authentication for management. The switch can assign two TACACS+ server for redundant authentication server
requirement.
Syslog
The Syslog is a standard for logging program messages . It allows separation of the software that generates
messages from the system that stores them and the software that reports and analyzes them. It is supported by a
wide variety of devices and receivers across multiple platforms.
LLDP (IEEE 802.1AB Link Layer Discovery Protocol)
The switch supports the LLDP that automated device discovery protocol for easy mapping by network management
applications.
Power Saving
The Power saving provides detection the client idle and cable length provide the different power. It could efficient to
save the switch power and reduce the power consumption.
