  • Page 39: Q Vlan Tags

    ENGLISH VLANs to span multiple 802.1Q-compliant switches through a single physical connection and allows Spanning Tree to be enabled on all ports and work normally. The IEEE 802.1Q standard restricts the forwarding of untagged packets to the VLAN of which the receiving port is a member.

  • Page 40: Tagging And Untagging

    ENGLISH Figure 7- 2. IEEE 802.1Q Tag The EtherType and VLAN ID are inserted after the MAC source address, but before the original EtherType/Length or Logical Link Control. Because the packet is now a bit longer than it was originally, the Cyclic Redundancy Check (CRC) must be recalculated.

  • Page 41: Default Vlans

    ENGLISH dropped. If the destination port is a member of the 802.1Q VLAN, the packet is forwarded and the destination port transmits it to its attached network segment. If the packet is not tagged with VLAN information, the ingress port will tag the packet with its own PVID as a VID (if the port is a tagging port).

  • Page 44: Trunking

    ENGLISH Trunking Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline. The Switch supports up to six port trunk groups with 2 to 8 ports in each group. A potential bit rate of 800 Mbps can be achieved.

  • Page 45: Link Aggregation

    ENGLISH Load balancing is automatically applied to the ports in the aggregated group, and a link failure within the group causes the network traffic to be directed to the remaining links in the group. The Spanning Tree Protocol will treat a link aggregation group as a single link, on the switch level. On the port level, the STP will use the port parameters of the Master Port in the calculation of port cost and in determining the state of the link aggregation group.

  • Page 46: Igmp Snooping

    ENGLISH IGMP Snooping Internet Group Management Protocol (IGMP) snooping allows the Switch to recognize IGMP queries and reports sent between network stations or devices and an IGMP host. When enabled for IGMP snooping, the Switch can open or close a port to a specific device based on IGMP messages passing through the Switch. In order to use IGMP Snooping it must first be enabled for the entire Switch (see Device Information).
  • Page 47 ENGLISH The following parameters may be viewed or modified: Parameter Description VLAN ID This is the VLAN ID that, along with the VLAN Name, identifies the VLAN for which to modify the IGMP Snooping Settings. VLAN Name This is the VLAN Name that, along with the VLAN ID, identifies the VLAN for which to modify the IGMP Snooping Settings.

  • Page 48: Static Router Ports Settings

    ENGLISH Static Router Ports Settings A static router port is a port that has a multicast router attached to it. Generally, this router would have a connection to a WAN or to the Internet. Establishing a router port will allow multicast packets coming from the router to be propagated through the network, as well as allowing multicast messages (IGMP) coming from the network to be propagated to the router.

  • Page 49: Spanning Tree

    ENGLISH Click Apply to implement the new settings, Click the Show All Static Router Port Entries link to return to the Current Static Router Port Entries window. Spanning Tree 802.1w Rapid Spanning Tree The Switch implements the Rapid Spanning Tree Protocol (RSTP) as defined by the IEEE 802.1w specification and a version compatible with the IEEE 802.1d STP.

  • Page 50: P2P Port

    ENGLISH P2P Port A P2P port is also capable of rapid transition. P2P ports may be used to connect to other bridges. Under RSTP, all ports operating in full-duplex mode are considered to be P2P ports, unless manually overridden through configuration.

STP Port Settings window In addition to setting Spanning Tree parameters for use on the switch level, the Switch allows for the configuration of groups of ports, each port-group of which will have its own spanning tree, and will require some of its own configuration settings.
  • Page 54 ENGLISH An STP Group spanning tree works in the same way as the switch-level spanning tree, but the root bridge concept is replaced with a root port concept. A root port is a port of the group that is elected based on port priority and port cost, to be the connection to the network for the group.

  • Page 55: Cos

    ENGLISH Section 8 802.1p Default Priority • 802.1p User Priority • The Switch supports 802.1p priority queuing Quality of Service. The following section discusses the implementation of CoS (Quality of Service) and benefits of using 802.1p priority queuing. Understanding IEEE 802.1p Priority Priority tagging is a function defined by the IEEE 802.1p standard designed to provide a means of managing traffic on a network where many different types of data may be transmitted simultaneously.
  • Page 56 ENGLISH Advantages of CoS CoS is an implementation of the IEEE 802.1p standard that allows network administrators a method of reserving bandwidth for important functions that require a large bandwidth or have a high priority, such as VoIP (voice-over Internet Protocol), web browsing applications, file server applications or video conferencing. Not only can a larger bandwidth be created, but other less critical traffic can be limited, so excessive bandwidth can be saved.

  • Page 57: Understanding Cos

    ENGLISH Understanding CoS The Switch has four priority classes of service. These priority classes of service are labeled as 3, the high class to 0, the lowest class. The eight priority tags, specified in IEEE 802.1p are mapped to the Switch's priority classes of service as follows: Priority 0 is assigned to the Switch's Q1 class.

  • Page 58: 802.1P Default Priority

    ENGLISH 802.1p Default Priority The Switch allows the assignment of a default 802.1p priority to each port on the Switch.

Figure 8- 2. 802.1p Default Priority window This window allows you to assign a default 802.1p priority to any given port on the Switch.

  • Page 59: 802.1P User Priority

    ENGLISH 802.1p User Priority When using 802.1p priority mechanism, the packet is examined for the presence of a valid 802.1p priority tag. If the tag is present, the packet is assigned to a programmable egress queue based on the value of the tagged priority.

  • Page 62: Authentication Process

    ENGLISH Client The Client is simply the endstation that wishes to gain access to the LAN or switch services. All endstations must be running software that is compliant with the 802.1x protocol. For users running Windows XP, that software is included within the operating system.
  • Page 63 ENGLISH Understanding 802.1x Port-based and MAC-based Network Access Control The original intent behind the development of 802.1x was to leverage the characteristics of point-to-point in LANs. As any single LAN segment in such infrastructures has no more than two devices attached to it, one of which is a Bridge Port.
