  • Page 38: Product Description

    Designed for use in industrial applications such as factory floors and control cabinets, industrial video surveillance systems with PoE, power utility substations, tariffed carrier field facilities, or transportation and oil and gas, the rugged Multilink ML810 handles stressful workloads (mixes of bursty data traffic and priority streaming traffic) as well as harsh environmental conditions.
  • Page 39: Packet Prioritization, 802.1p Qos

    Quality of Service means providing consistent predictable data delivery to users from datagram paths that go all across a network. As a LAN device, the Multilink ML810 can do its part to prevent any QOS degradation while it is handling Ethernet traffic through its ports and buffers.
  • Page 40: Features And Benefits

    • Managed switching for high performance Ethernet LANs Multilink ML810 Switches provide unicast non-blocking (all ports can run at full speed at once) performance with standard Managed Network Software. They are typically used in LAN traffic centers with up to 8 100Mb +2 Gigabit ports for backbone connections, where managed network services are desired.

  • Page 47: Connecting Ethernet Media

    3.2.1 Connecting Twisted Pair (CAT3, CAT5, UTP or STP) The RJ-45 ports of the Multilink ML810 can be connected to the following two media types: 100BASE-TX and 10BASE-T. CAT 5 cables should be used when making 100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT 3 may be used. In either case, the maximum distance for unshielded twisted pair cabling is 100 meters (328 ft).

    RJ-45 port separately. For detail information See Section 2.3 of this manual for information to access the “6K-MNS Software user guide” One frequently-used application for the Managed Multilink ML810 Switch copper ports is to connect one of them using a fiber media converter to another Switch in the network backbone, or to some other remote 100Mb device.
  • Page 59 When operating in 100Mb half-duplex mode, cable distances and hop-counts may be limited within that collision domain. The Path Delay Value (PDV) bit-times must account for all devices and cable lengths within that domain. For Multilink ML810 Fast Ethernet switched ports operating at 100Mb half-duplex, the bit time delay is 50BT.
  • Page 60: Flow-control, Ieee 802.3x Standard

    CHAPTER 4: OPERATION Flow-control, IEEE 802.3x standard Multilink ML810 Switches incorporate a flow-control mechanism for Full-Duplex mode. The purpose of flow-control is to reduce the risk of data loss if a long burst of activity causes the switch to save frames until its buffer memory is full. This is most likely to occur when data is moving from a 100Mb port to a 10 Mb port and the 10Mb port is unable to keep up.

    VLAN (broadcast domain) can be extended across a large network. 802.1Q-compliant switch ports, such as those on the MultiLink ML810 Managed Edge Switch, can be configured to transmit tagged or untagged frames. A tag field containing VLAN information can be inserted into an Ethernet frame.
  • Page 168 If the port also wants to send broadcast traffic, the proper leave (sending out of information) and join rules (receiving information) have to be configured on the MultiLink ML810 Managed Edge Switch. It is recommended to use IEEE 802.1q tagged based VLANs over port based VLANs because of there multi-vendor interoperability and capability of carrying the isolated tagged VLAN information when more than one switch is involved.

    14.1.2 QoS Concepts The MultiLink ML810 Managed Edge Switch supports QoS as specified in the IEEE 802.1p and IEEE 802.1q standards. QoS is important in network environments where there are time-critical applications, such as voice transmission or video conferencing, which can be adversely effected by packet transfer delays or other latency in a network.
  • Page 232: Diffserv And Qos

    To make the preemptive queuing possible, most switches implement at least two queue buffers. The MultiLink ML810 Managed Edge Switch has two priority queues, 1 (low) and 0 (high).When tagged packets enter a switch port, the switch responds by placing the packet into one of the two queues, and depending on the precedence levels the queue could be rearranged to meet the QoS requirements.
  • Page 233 ToS byte. The MultiLink ML810 Managed Edge Switch has the capability to provide QoS at Layer 2. At Layer 2, the frame uses Type of Service (ToS) as specified in IEEE 802.1p. ToS uses 3 bits, just like IP precedence, and maps well from Layer 2 to layer 3, and vice versa.
  • Page 234: Configuring Qos Through The Command Line Interface
