  • Page 27: Ip Address Assignment

    Fig. 2-10 the Login Screen for Web 2-1-5. IP Address Assignment For IP address configuration, there are three parameters needed to be filled in. They are IP address, Subnet Mask, Default Gateway and DNS. IP address: The address of the network device in the network is used for internetworking communication.
  • Page 28 With the classful addressing, it divides IP address into three classes, class A, class B and class C. The rest of IP addresses are for multicast and broadcast. The bit length of the network prefix is the same as that of the subnet mask and is denoted as IP address/X, for example, 192.168.1.0/24.
  • Page 29 Class D and E: Class D is a class with first 4 MSB (Most significance bit) set to 1-1-1-0 and is used for IP Multicast. See also RFC 1112. Class E is a class with first 4 MSB set to 1-1-1-1 and is used for IP broadcast. According to IANA (Internet Assigned Numbers Authority), there are three specific IP address blocks reserved and able to be used for extending internal network.
  • Page 30 In this diagram, you can see the subnet mask with 25-bit long, 255.255.255.128, contains 126 members in the sub-netted network. Another is that the length of network prefix equals the number of the bit with 1s in that subnet mask. With this, you can easily count the number of IP addresses matched.
  • Page 31 For different network applications, the subnet mask may look like 255.255.255.240. This means it is a small network accommodating a maximum of 15 nodes in the network. Default gateway: For the routed packet, if the destination is not in the routing table, all the traffic is put into the device with the designated IP address, known as default router.

  • Page 80: Igmp Snooping

    3-8. IGMP Snooping The function, IGMP Snooping, is used to establish the multicast groups to forward the multicast packet to the member ports, and, in nature, avoids wasting the bandwidth while IP multicast packets are running over the network. This is because a switch that does not support IGMP or IGMP Snooping can not tell the multicast packet from the broadcast packet, so it can only treat them all as the broadcast packet.
  • Page 81 Parameter description: IGMP snooping mode selection: The switch supports three kinds of IGMP Snooping status, including “Passive”, “Active” and “Disable”. Disable: Set “Disable” mode to disable IGMP Snooping function. Default: Disable Active: In Active mode, IGMP snooping switch will periodically issue the Membership Query message to all hosts attached to it and gather the Membership report message to update the database of the Multicast table.

VLAN configuration is used to partition your LAN into small ones as your demand. Properly configuring it, you can gain not only improving security and increasing performance but greatly reducing VLAN management.
  • Page 85 Metro Mode: The Metro Mode is a quick configuration VLAN environment method on Port-based VLAN. It will create 6 or 7 Port-based VLAN groups. Double-tag: Double-tag mode belongs to the tag-based mode, however, it would treat all frames as the untagged ones, which means that tag with PVID will be added into all packets.
  • Page 86 Up-link Port: This function is enabled only when metro mode is chosen in VLAN mode. Except Port 7, each port of the switch cannot transmit packets with each other. Each port groups a VLAN with Port 7, thus, total 7 groups consisting of 2 members are formed.
