GS-2124C User Manual 2. Installation 2-1. Starting GS-2124C Up This section will give users a quick start for: - Hardware and Cable Installation - Management Station Installation - Software booting and configuration 2-1-1.
GS-2124C User Manual • TP Port and Cable Installation ⇒ In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of cable, straight-through (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in 10/100M TP; 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and crossed-over (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 3, 6, 1, 2) can be used. It means you do not have to tell from them, just plug it. ⇒ Use Cat.
GS-2124C User Manual 2-1-2-1. Cabling Requirements for TP Ports ⇒ For Fast Ethernet TP network connection The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100 meters. ⇒ Gigabit Ethernet TP network connection The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100 meters. Cat. 5e is recommended. 2-1-2-2. Cabling Requirements for 1000SX/LX SFP Module It is more complex and comprehensive contrast to TP cabling in the fiber media.
GS-2124C User Manual 2-1-2-3. Switch Cascading in Topology • Takes the Delay Time into Account Theoretically, the switch partitions the collision domain for each port in switch cascading that you may up-link the switches unlimitedly. In practice, the network extension (cascading levels & overall diameter) must follow the constraint of the IEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which the limitations are the timing requirement from physical signals defined by 802.
GS-2124C User Manual Case1: All switch ports are in the same local area network. Every port can access each other (See Fig. 2-2). Fig. 2-2 No VLAN Configuration Diagram If VLAN is enabled and configured, each node in the network that can communicate each other directly is bounded in the same VLAN area. Here VLAN area is defined by what VLAN you are using. The switch supports both port-based VLAN and tag-based VLAN. They are different in practical deployment, especially in physical location.
GS-2124C User Manual Case 2b: Port-based VLAN (See Fig.2-4). Fig. 2-4 Port-based VLAN Diagram 1. VLAN1 members could not access VLAN2, VLAN3 and VLAN4 members. 2. VLAN2 members could not access VLAN1 and VLAN3 members, but they could access VLAN4 members. 3. VLAN3 members could not access VLAN1, VLAN2 and VLAN4. 4. VLAN4 members could not access VLAN1 and VLAN3 members, but they could access VLAN2 members. Case3a: The same VLAN members can be at different switches with the same VID (See Fig. 2-5). Fig.
GS-2124C User Manual 2-1-3. Configuring the Management Agent of GS-2124C We 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. You can touch them through the following procedures.
GS-2124C User Manual 2-1-3-1. Configuring the Management Agent of GS-2124C 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. Next, run a terminal emulator with the default setting of the switch’s serial port. With this, you can communicate with the switch. In the switch, RS-232 interface only supports baud rate 57.
GS-2124C User Manual • Set IP Address, Subnet Mask and Default Gateway IP Address Please refer to Fig. 2-6 Console Management for details about the ex-factory setting. 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. For example, your network address is 10.1.1.0, and subnet mask is 255.255.255.0. You can change the switch’s default IP address 192.168.1.1 to 10.1.1.
GS-2124C User Manual 2-1-3-2. Configuring the Management Agent of GS-2124C 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. 24 Gigabit L2 Managed Switch Default IP Setting: IP = 192.168.1.1 Subnet Mask = 255.255.255.0 Default Gateway = 192.168.1.
GS-2124C 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. Its address structure looks is shown in the Fig. 2-10. It is “classful” because it is split into predefined address classes or categories.
GS-2124C 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. Each class has its address range described below. Class A: Address is less than 126.255.255.255. There are a total of 126 networks can be defined because the address 0.0.0.
GS-2124C 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. According to IANA (Internet Assigned Numbers Authority), there are three specific IP address blocks reserved and able to be used for extending internal network. We call it Private IP address and list below: Class A Class B Class C 10.0.0.0 --- 10.255.255.255 172.16.0.
GS-2124C 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. The following table shows the result. Prefix Length No. of IP matched No.
GS-2124C 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. Basically, it is a routing policy. The gateway setting is used for Trap Events Host only in the switch.
GS-2124C User Manual 2-2.

When DHCP is disabled, Default: 192.168.1.1 If DHCP is enabled, this field is filled by DHCP server and will not allow user manually set it any more.
GS-2124C User Manual DNS: It is Domain Name Server used to serve the translation between IP address and name address. The switch supports DNS client function to re-route the mnemonic name address to DNS server to get its associated IP address for accessing Internet. User can specify a DNS IP address for the switch. With this, the switch can translate a mnemonic name address into an IP address. There are two ways to specify the IP address of DNS.
GS-2124C User Manual 3-1-3. Time Configuration The switch provides manual and automatic ways to set the system time via NTP. Manual setting is simple and you just input “Year”, “Month”, “Day”, “Hour”, “Minute” and “Second” within the valid value range indicated in each item. If you input an invalid value, for example, 61 in minute, the switch will clamp the figure to 59. NTP is a well-known protocol used to synchronize the clock of the switch system time over a network.
GS-2124C User Manual NTP: NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean Time (GMT). If use the NTP mode and select a built-in NTP time server or manually specify an user-defined NTP server as well as Time Zone, the switch will sync the time in a short after pressing button. Though it synchronizes the time automatically, NTP does not update the time periodically without user’s processing. Time Zone is an offset time off GMT.

GS-2124C User Manual 3-3. Mirror Function name: Mirror Configuration Function description: Mirror Configuration is to monitor the traffic of the network. For example, we assume that Port A and Port B are Monitoring Port and Monitored Port respectively, thus, the traffic received by Port B will be copied to Port A for monitoring. Note: When configuring the mirror function, you should avoid setting a port to be a sniffer port and aggregated port at the same time. It will cause something wrong.
GS-2124C User Manual 3-4. Bandwidth Management Function name: Bandwidth Management Function description: Bandwidth Management function is used to set up the limit of Ingress and Egress bandwidth for each port. Note: Each port of the switch owns 16KB packet buffer. The packet buffer size will be reduced when the bandwidth rate limitation is enabled, which may cause that jumbo frame cannot be forwarded. Please avoid enabling jumbo frame and bandwidth rating functions at the same time. Fig.
GS-2124C User Manual Broadcast & Multicasat for Ingress Rate Limiting (Policing): Set up the limit of Ingress bandwidth for the port you choose. Incoming traffic will be discarded if the rate exceeds the value you set up in Data Rate field. The format of the packet limits to broadcast and multicast. Valid range is 0~1000.

GS-2124C User Manual 3-5. QoS(Quality of Service) Configuration The switch offers powerful 5 kinds of QoS functions. There are Per Port Priority that you can assign each port to different precedence, VLAN Tag priority that can make precedence of 8 priorities, IP TOS Classification, IP TCP/UDP Port Classification and IP DiffServe Classification. In Quality of Service (QoS) Configuration, there is one option named” Default Class”.
GS-2124C User Manual Function name: Per Port Priority Function description: We can assign QoS Priority, including High and Low for each port. For example, if we transmit IP packets from Port 2 and Port 3 at the speed of 1Gbps to Port 1, and set the Class of Port 2 as High and Port 3 as Low, then the packets of Port 3 will be dropped when the congestion happens because Port 2 owns higher precedence of transmitting packets.
GS-2124C User Manual Function name: VLAN Tag Priority Function description: In vlan tag, there are 3 bits belonging to priority. According to these 3 bits, we could arrange 8 traffics –0 0 0, 0 0 1, 0 1 0, 0 1 0, 1 0 0, 1 0 1, 1 1 0, 1 1 1. We can set High priority or Low priority for each traffic class. For instance, if we let VLAN-tagged priority 0 0 0 be high priority and VLAN-tagged priority 0 0 1 be Low Priority, and then make port 1, 2, 3 be in the vlan 2.
GS-2124C User Manual Bit 0, Bit 1, Bit 2: According to the arrangement of VLAN-tagged priority, it can form 8 kinds of traffics, including 0 0 0, 0 0 1, 0 1 0, 0 1 0, 1 0 0, 1 0 1, 1 1 0 and 1 1 1. Class: 8 kinds of traffic as mentioned above, user can set up High Priority or Low Priority for each port respectively.
GS-2124C User Manual Function name: IP ToS Classification Function description: Another QoS function is the application of Layer 3 on network framework. We focus on TOS field of IP header. There are three bits in TOS field. We means bit 2~4 of TOS field that we will use. According to these 3 bits, we could arrange 8 traffics –0 0 0, 0 0 1, 0 1 0, 0 1 0, 1 0 0, 1 0 1, 1 1 0, 1 1 1. As long as we change bit 5~7 of TOS field of IP header, we will create the 8 traffic packets we meant before.
GS-2124C User Manual Bit 0, Bit 1, Bit 2: According to the arrangement of Bit 5 ~ Bit 7 in TOS Field of IP Header, it can form 8 kinds of traffics, including 0 0 0, 0 0 1, 0 1 0, 0 1 0, 1 0 0, 1 0 1, 1 1 0 and 1 1 1. Class: 8 kinds of traffic as mentioned above, user can set up High Priority or Low Priority for each port respectively.
GS-2124C User Manual Function name: IP TCP/UDP Port Classification Function description: In L4 QoS Configuration, you can enter one of these special network transmission events, for example we use” Down prioritize web browsing, e-mail, FTP and news “L4 QoS Configuration and click apply, and then click Custom L4.
