  • Page 35: Igmp

    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.

    This specifies the maximum amount of time in seconds between the Switch receiving a leave group message from a host, and the Switch issuing a group membership query. If no response to the membership query is received before the Leave Timer expires, the (multicast) forwarding entry for that host is deleted.

  • Page 37: Spanning Tree

    802.1w Rapid Spanning Tree The Switch implements two versions of the Spanning Tree Protocol, Rapid Spanning Tree Protocol (RSTP) as defined by the IEEE 802.1w specification and a version compatible with the IEEE 802.1d STP. RSTP can operate with legacy equipment implementing IEEE 802.1d, however the advantages of using RSTP will be lost.

  • Page 38: Edge Port

    RSTP. The Spanning Tree Protocol (STP) operates on two levels: 1. On the switch level, the settings are globally implemented. 2. On the port level, the settings are implemented on a per user-defined group of ports basis.

    Setting this parameter as "Yes" will set the ports to send out BDPU packets to other bridges, requesting information on their STP setting If the Switch is configured for RSTP, the port will be capable to migrate from 802.1d STP to 802.1w RSTP. RSTP can coexist with standard STP, however the benefits of RSTP are not realized on a port where an 802.1d network connects to an 802.1w enabled network.

Static Multicast Forwarding Settings window The Static Multicast Forwarding Settings window displays all of the entries made into the Switch's static multicast forwarding table.

  • Page 44: Vlans

    A weighted round robin system is employed on the Switch to determine the rate at which the queues are emptied of packets. The ratio used for clearing the queues is 4:1. This means that the highest priority queue, Queue 1, will clear 4 packets for every 1 packet cleared from Queue 0.

    VLANs without a network device performing a routing function between the VLANs. The DGS-3024 supports IEEE 802.1Q VLANs. The port untagging function can be used to remove the 802.1Q tag from packet headers to maintain compatibility with devices that are tag-unaware.

  • Page 46: 802.1Q Vlan Tags

    DGS-3024 Gigabit Ethernet Switch Manual Figure 6- 15. IEEE 802.1Q Packet Forwarding 802.1Q VLAN Tags The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address. Their presence is indicated by a value of 0x8100 in the EtherType field. When a packet's EtherType field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.

  • Page 48: Tagging And Untagging

    Switch will drop the packet. Because of the existence of the PVID for untagged packets and the VID for tagged packets, tag-aware and tag-unaware network devices can coexist on the same network. A switch port can have only one PVID, but can have as many VIDs as the Switch has memory in its VLAN table to store them.

  • Page 49: Default Vlans

    Default VLANs The Switch initially configures one VLAN, VID = 1, called "default." The factory default setting assigns all ports on the Switch to the "default." Packets cannot cross VLANs. If a member of one VLAN wants to connect to another VLAN, the link must be through an external router.

  • Page 51: Gvrp Settings

    In the Configuration menu, open the VLANs folder and click GVRP Settings. The GVRP Settings window, shown below, allows you to determine whether the Switch will share its VLAN configuration information with other GARP VLAN Registration Protocol (GVRP) enabled switches. In addition, Ingress Checking can be used to limit traffic by filtering incoming packets whose PVID does not match the PVID of the port.
  • Page 52 The following fields can be set: Parameter Description These two fields allow you to specify the range of ports that will be included in the From/To VLAN that you are creating using the GVRP Settings window. Ingress Check This field can be toggled using the space bar between Enabled and Disabled. Enabled enables the port to compare the VID tag of an incoming packet with the PVID number assigned to the port.

  • Page 57: Qos

    The picture above shows the default priority setting for the Switch. Class-3 has the highest priority of the four priority queues on the Switch. In order to implement QoS, the user is required to instruct the Switch to examine the header of a packet to see if it has the proper identifying tag tagged.
  • Page 58 CoS until there are no more packets for this CoS. The other CoS queues that have been given a nonzero value, and depending upon the weight, will follow a common weighted round-robin scheme. Remember that the DGS-3024 has four priority queues (and four Classes of Service) for each port on the Switch. Priority 0 is assigned to the Switch's Q1 queue.

  • Page 62: Link Aggregation

    Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline. The DGS-3024 supports up to four port trunk groups with 2 to 8 ports in each group. A potential bit rate of 8000 Mbps can be achieved.
  • Page 63 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 106: Mac Address

    MAC Address This allows the Switch's dynamic MAC address forwarding table to be viewed. When the Switch learns an association between a MAC address and a port number, it makes an entry into its forwarding table. These entries are then used to forward packets through the Switch.
  • Page 107 The following fields can be viewed or set: Parameter Description VLAN ID Enter a VLAN ID for the forwarding table to be browsed by. MAC Address Enter a MAC address for the forwarding table to be browsed by. Find Allows the user to move to a sector of the database corresponding to a user defined port, VLAN, or MAC address.

    RAM, and will immediately take effect. Some settings, though, require you to restart the Switch before they will take effect. Restarting the Switch erases all settings in RAM and reloads the stored settings from the NV-RAM. Thus, it is necessary to save all setting changes to NV-RAM before rebooting the Switch.

  • Page 118: Reboot Services

    Figure 9- 7. Save Configuration Confirmation dialog box Click the OK button to continue. Once the Switch configuration settings have been saved to NV-RAM, they become the default settings for the Switch. These settings will be used every time the Switch is rebooted.

  • Page 119: Reset System

    Reset gives the option of retaining the Switch's User Accounts and History Log while resetting all other configuration parameters to their factory defaults. If the Switch is reset using this window, and Save Changes is not executed, the Switch will return to the last saved configuration when rebooted.
