Page 24: Configuring The Management Agent Of The Switch
User Manual 2 -1-4. Configuring the Management Agent of the switch W e offer you three ways to startup the switch management function. They are RS- 232 console, CLI, and Web. Users can use any one of them to monitor and configure the switch.
Page 25 User Manual 2-1-4-1. Configuring the Management Agent of the switch through the Serial RS-232 Port To perform the configuration through RS-232 console port, the switch’s serial port must be directly connected to a DCE device, for example, a PC, through RS-232 cable with DB-9 connector.
Page 26 User Manual • Set IP Address, Subnet Mask and Default Gateway IP Address Please refer to Fig. 2-7 CLI Management for details. They are default setting of IP address. You can first either configure your PC IP address or change IP address of the switch, next to change the IP address of default gateway and subnet mask.
Page 27 User Manual 2-1-4-2. Configuring the Management Agent of the switch through the Ethernet Port There are three ways to configure and monitor the switch through the switch’s Ethernet port. They are CLI, Web browser and SNMP manager. The user interface for the last one is NMS dependent and does not cover here. We just introduce the first two types of management interface.
Page 28: Ip Address Assignment
User Manual Fig. 2-10 t he 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 29 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 30 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 31 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 32 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.

These 64-entry table are addressed by 6-bit DSCP field from the IP header. This table may be configured arbitrarily, however, it is recommended that lower-value entries relate to lower-priority levels.
Page 75 User Manual Function name: Priority – Port Priority Setting Function description: Set Priority State for every port. Upon reception, each packet is assigned a priority value. The most basic priority assignment comes from the receive port’s default priority. This default port priority is used whenever Layer 2 (VLAN) and Layer 3 (IP) priority information is not available.

Page 98: Igmp Snooping
User Manual 3-11. 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 99 User Manual Parameter description: IGMP snooping: The switch supports two kinds of IGMP Snooping status, including “Enable”, and “Disable”.

Page 116: Gvrp Configuration
User Manual 3-14. GVRP Configuration GVRP is an application based on Generic Attribute Registration Protocol (GARP), mainly used to automatically and dynamically maintain the group membership information of the VLANs.

Page 122: Configuration
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 123 User Manual The overview of operation flow for the Fig. 3-53 is quite simple. When Supplicant PAE issues a request to Authenticator PAE, Authenticator and Supplicant exchanges authentication message. Then, Authenticator passes the request to RADIUS server to verify. Finally, RADIUS server replies if the request is granted or denied.
Page 124 User Manual Authentication server Fig. 3-62 Authenticator Supplicant A The Fig. 3-55 shows the procedure of 802.1X authentication. There are steps for the login based on 802.1X port access control management. The protocol used in the right side is EAPOL and the left side is EAP. At the initial stage, the supplicant A is unauthenticated and a port on switch acting as an authenticator is in unauthorized state.
Page 125 User Manual If user ID and password is correct, the authentication server will send a Radius-Access-Accept to the authenticator. If not correct, the authentication server will send a Radius-Access-Reject. When the authenticator PAE receives a Radius-Access-Accept, it will send an EAP-Success to the supplicant. At this time, the supplicant is authorized and the port connected to the supplicant and under 802.1X control is in the authorized state.
Page 126 User Manual Only MultiHost 802.1X is the type of authentication supported in the switch. In this mode, for the devices connected to this port, once a supplicant is authorized, the devices connected to this port can access the network resource through this port.
