FMS-24K
24Ports 10M/100M Stackable Intelligent Switch
 
 
Supports Stacking
  FMS-24K provides the capability of stacking up to 8 units, which is able to support maximum of up to 192 10/100Mbps ports and 8 uplink Gigabit ports. The stacking module should be installed in Module 1 slot.The stacking module provides two USB interfaces, one is for uplink and the other is for down link. The bandwidth of the stacking module is 1Gbps.
 
Intelligent Management Features
  The product supports SNMP, RMON as well as a protocol for controlling multicast packets. When combined with other intelligent switch products, the switch allows the construction
of networks supporting superior management functions. Network configuration can be performed via Telnet, WWW browser as well as the product's console serial port. The web browser interface eases network management via its GUI-based configuration screens.
 
Link Aggregation
  Fully compliant with IEEE802.3ad Link Aggregation, the product supports Trunk connection to switches from other vendors that comply with the Link Aggregation feature. It can aggregate up to 2/3/4 ports per trunk group and supports a total of 6 trunk groups.
 
Port Mirroring
  Supports port mirroring, a function that copies packets sent or received on a specific port to another port. Using this feature, the user can attach a monitoring device such as Sniffer or Rmon probe to analyze the details of the packets that pass the source port.
 
Multiple Spanning Tree (Future release)
  The IEEE 802.1s is the supplement to IEEE Std 802.1Q adds the facility for VLAN bridges to use multiple spanning trees, providing for traffic belonging to different VLANs to flow over potentially different paths within the virtual bridged LAN. 802.1s supports spanning tree by per VLAN.
 
VLAN and QoS Improve Network Availability
 

Support the following VLAN features:

(i) Support 256 VLANs.
(ii) 802.1Q VLAN Tagging. 802.1Q provides a method for tagging frames with explicit VLAN identification. The VLAN tag allows one device to map a frame to a given VLAN base on a set of association rules 802.1Q also specifies how tags are inserted and/or stripped as frame propagate in and out of a VLAN aware switch. The FMS-24K supports 802.3ac Frame Extension for VLAN tagging.
(iii) Private VLAN A Private VLAN is a Layer 2 security feature providing port-based security and isolation between adjacent ports within a VLAN. It is an extension, of the common VLAN. Private VLAN Edge provides security and isolation between ports on a switch so that traffic from "protected" ports is only sent to the uplinks and cannot travel to another port within a switch, thereby keeping calls private. When private VLAN edge is enabled, there is no forwarding of unicast, broadcast, or multicast traffic between ports on a switch, and all traffic between ports on the switch must be forwarded through a designated (router) Layer 3 device. Private VLAN enables per port security, requiring only a VLAN on every switch, not every port. This feature greatly minimizes the number of VLANs required. Private VLANs and normal VLANs can exist
simultaneously in the same switch.

 
GVRP Protocol for VLAN configuration
  GVRP (GARP VLAN Registration Protocol), a registration protocol specifically for VLANs. GVRP may be used in end stations and in switches. Using this protocol, stations request admission to specific VLANs. Membership in a VLAN is determined by a network management or policy system, and GVRP helps simplify the administration of VLANs in several ways. It handles registration of end stations with Ethernet switches and maintains current information about membership. The protocol may be used between end stations across a large network.
 
Multicast Filtering
  Supports IGMPv1/IGMPv2 snooping (RFC1112/RFC2236).Layer-2 IGMP Snooping switch is also responsible for forwarding the IGMP traffic it is receiving. IGMP Membership Reports will only be forwarded to the set of ports where IP multicast capable device have been heard.
 
WRR (Weighted Round Robin)
  Supports Weighted Round Robin (WRR) scheduling. The WRR queuing algorithm ensures that the lower priority packets are not entirely starved for bandwidth and are serviced without compromising the priority settings administered by the network manager.
 
Bandwidth Management (Rate Limiting)
  This function allows the network manager to control the maximum rate for traffic transmitted or received on a port. Rate limiting is configured on ports at the edge of a network to limit traffic into or out of the network. Traffic that falls within the rate limit is transmitted, while packets that exceed the acceptable amount of traffic are dropped. Rate limiting can be applied to individual ports. When a port is configured with this feature, the traffic rate will be monitored by the hardware to verify conformity. Non-conforming traffic is dropped and conforming traffic is forwarded without any changes. FMS-24K offers 10 levels of bandwidth management. Each level offers 10Mb/s.
 
Duplication of Management file
  The FMS-24K can copy those three types of files in three different ways.
1. Local file to local file copy: The FMS-24K can copy an existed local Configuration File to another local file.
Copy exited local Operation Code to another local file is not permitted.
2. Remote TFTP Server to Local file copy: The FMS-24K can support to download Configuration File or Operation Code from remote server to local file.
3. Local file to remote server: The FMS-24K can support to upload an existed local Configuration File to the remote server.
4. Running Config to local file copy
5. Running Config to remote TFTP server
6. Local file to Running Config copy
7. Remote TFTP server to Running Config copy
