  • Page 23: Ip Address Assignment

    User Manual Fig. 2-9 the Login Screen for Web 2-1-4. 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 24 User Manual 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 25 User Manual 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.
  • Page 26 User Manual 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 27 User Manual 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.

    User Manual 3-15. 802.1x Configuration 802.1x port-based network access control provides a method to restrict users to access network resources via authenticating user’s information. This restricts users from gaining access to the network resources through a 802.1x-enabled port without authentication. If a user wishes to touch the network through a port under 802.1x control, he (she) must firstly input his (her) account name for authentication and waits for gaining authorization before sending or receiving any packets from a 802.1x-enabled port.
  • Page 116 User Manual The overview of operation flow for the Fig. 3-49 is quite simple.
