  • Page 35: Snmp Configuration

    IP DiffServ Classification IP DiffServ Classification (Figure 3-21) works by prioritizing traffic based on the 8-bit Service Type field in each packet as defined by the IETF for differentiated services. Under the differentiated services interpretation, the first six bits comprise a codepoint, which is sometimes abbreviated DSCP, and the last two bits are left unused.

    IGMP Snooping, multicast packet forwarding is effectively the same as broadcast packet forwarding. A switch that supports IGMP Snooping with query, report and leave functions based on a type of packet exchanged between the IP Multicast Router/Switch and IP Multicast Host can update the information in the Multicast table when a member (port) joins or leaves an IP Multicast Destination Address.

  • Page 38: Dhcp Boot

    Figure 3-24: Maximum Packet Length Page 3.9 DHCP Boot The DHCP Boot page (Figure 3-25) allows the user to configure the boot up and DHCP request delay for the switch. Enabling DHCP Broadcast Suppression will cause the switch to delay booting up for between 1 and 30 seconds to avoid overloading the DHCP server with requests in the event of a building-wide power failure.

  • Page 39: Tag-Based Group

    Tag-based: Tag-based VLANs are identified by its VLAN ID or VID. Instead of filtering by port, all packets coming into and out of the switch are filtered based on the VLAN ID in the packet, and are grouped accordingly. The switch supports 802.1Q tag-based VLANs. Each tag-based VLAN must be assigned a unique VLAN name and VLAN ID.

For example, if port x receives an untagged packet, the switch will apply the PVID (assume as VID y) of port x to tag this packet, the packet then will be forwarded as a tagged packet with VID y.

  • Page 49: Stp Configuration

    3.13 STP Configuration The Spanning Tree Protocol (STP) is a standardized method (IEEE 802.1D) for avoiding loops in switched networks. When STP is enabled, the switch ensures that only one path is active between any two nodes on the network at a time. It is recommended that you enable STP on all switches to ensure a single active path on the network.

  • Page 50: Configuration

    Bridge Priority: The lower the bridge priority, the higher the priority it has. Usually, the bridge with the highest bridge priority is the root. If you want to have the SS2GD8I as the root bridge, you should set this value lower than that of the other bridges in the LAN. Valid values are from 0-61440. The default is 32768.

  • Page 51: Port

    seconds. Default is 20 seconds. Forward Delay: Set the root bridge forward delay time. This figure is set by the root bridge only. The forward delay time is defined as the time spent from Listening state moving to Learning state and also from Learning state moving to Forwarding state of a port in a bridge.

  • Page 52: Trunking Configuration

    a device that knows nothing about STP or RSTP. Usually, the connected device is an end station. Edge Ports will immediately transit to forwarding state and skip the listening and learning state because the edge ports cannot create bridging loops in the network. This will expedite the convergence. When the link on the edge port toggles, the STP topology remains unchanged.
