EKI-7657C _Manua l_ed1 40 Figure 3.7: Main page.
41 Chapter3 3.2.1 System System Information Here you can view the system information and assign the system name and loca tion to make this switch more easily to be identified on your network. • System Name : Assign the name of the switch. The maximum length is 64 bytes.
EKI-7657C _Manua l_ed1 42 IP Configuration User can configure the IP Settings and DHCP client function here. • DHCP Client : Enable or di sable the DHCP client function. When DHCP client function is en abled, the industrial switch will be assigned an IP address from the network DHCP se rver .
43 Chapter3 DHCP Server—System configura tion DHCP is the abbreviation of Dynamic Host Configuration Proto col t hat is a protocol for assigning dynamic IP addresses to d evices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network.
EKI-7657C _Manua l_ed1 44 Figure 3.11: DHCP Server – Client Entries DHCP Server—Port and IP Bindings Assign the dynamic IP addre ss to the port. When the device is con necting to the port and asks for IP assigning, the system will assign t he IP address that has been assigned b e fore to the connected device.
45 Chapter3 TFTP—Update Firm ware Trivial File Transfer Protocol (TFTP) is a very simple f ile transfer protocol, with the functionality of a very basic form of FTP.
EKI-7657C _Manua l_ed1 46 Figure 3.14: TFTP – Restore Configuration TFTP—Backup Configuration You can save current Flash ROM value f rom the switch to TFTP server for restoring later. • TFTP Server IP Address: Fill in the TFTP server IP • Backup File Name: Fill in the file name • Click A pply .

55 Chapter3 Digital Input/Output The EKI-7657C contains two digital in puts and two digital outputs. The digita l inputs may be used to receive the voltage-changing sig nal of the remote equi pment to sense the state of the remote equipment like heater, pump, and oth er electrical equipme nt.
EKI-7657C _Manua l_ed1 56 Figure 3.23: Digital Input/Output interface.
57 Chapter3 3.2.2 Port Port setting includes Port Statistics , Port Control, Po rt Trunk, Port Mirroring, an d Rate Limiting. The user can use this interface to set the parameters a nd control the packet flow among the ports. Port Statistics The following information provides t he current port statistic inform ation.
EKI-7657C _Manua l_ed1 58 Port Control In Port Control, you can pull down the selection items to set the parameters of each port to co ntrol the transmitting/receiving packets. • Port: Select the port that you want to configure. • State: Current port status.
59 Chapter3 Port Trunk The Link Aggregation Control Protocol (LA CP) provides a standardized means for exchangin g information between Partner System s on a link to allo w their Li nk Aggregation C on.
EKI-7657C _Manua l_ed1 60 Figure 3.26: 2 work ports with LACP enabled Aggregator Information When you have set up the aggregator setting with LACP disabled, you will see the local static trunk g roup information as below.
61 Chapter3 Figure 3.28: Static trunking group of 2 ports on sin gle switch When you have set up the aggregator setting of two inte rconnected switches with LACP enabled, you will see the respective LACP t runk group information as below. ‘Actor’ mean s the switch which is conne cting to the host computer.
EKI-7657C _Manua l_ed1 62 because both ports are waiting for an LA CP protocol packet from the opposite device. Figure 3.30: State Activity.
63 Chapter3 Port Mirroring The Port mirroring is a method for m onitoring traffi c in switched n etworks. Traffic through ports can be monitored by one specific port which means traffic goes in or out monitored (source ) ports will be duplicated into mirroring (d estination) port.
EKI-7657C _Manua l_ed1 64 Rate Limiting Here you can set up every port’ s frame limit ation type and bandwid th rate. • Ingress Limit Frame type: Select the frame type you want to filter . The frame types have 4 options for selecting: All, Broadcast/Multicast/Flooded Unicast, Broadcast/Multicast, and Broadcast only .
65 Chapter3 3.2.3 Protocol The user can set the layer 2 protocol setting via this interface. VLAN configuration A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, whi ch would allow you to isolate network traffic, so only the members of the same VLAN will receiv e traffic from the ones of the same VLAN.
EKI-7657C _Manua l_ed1 66 Figure 3.34: Port based mode • Pull down the selection item and focus on Port Based then pres s A ppl y to set the VLAN Operation Mode in Port Based mode.

EKI-7657C _Manua l_ed1 70 • Click Ed it . Figure 3.38: Edit Group C onfiguration interface • You can Change the VLAN group na me and VLAN ID. Figure 3.
71 Chapter3 The Rapid Spanning Tree Protocol (RS TP) is an evolut ion of the Spanning Tree Protocol and provides for faster spanning tree converge nce after a topology change. The system also supports S TP and the system will auto-detect the connected d evice that is running STP or RSTP protocol.
EKI-7657C _Manua l_ed1 72 RSTP—System Configur ation • The user can view spanning tree inform ation of the Root Bridge. • The user can modify RSTP st ate. After modification, click A pp l y . ¾ RSTP mode: The user must enable the RSTP function first before configuring the related parameters.
73 Chapter3 • Admin P2P: Some of the rapid state transactions that are possible within RST P are dependent upo n whether the port concerned ca n only be connected to exactly one other b ridge (i.e. it is served by a point-to-point LAN segment), or can be con nected to two or more bridges (i.
EKI-7657C _Manua l_ed1 74 SNMP Configuration Simple Network Management Protocol (SNMP) is the protocol develop ed to manage nodes (servers, workstations, routers, switches and hubs etc.) on an IP network. SNMP enables network administrators to manage network performance, find and solve netwo rk problems, and plan for network g rowth.
75 Chapter3 A trap manager is a management station that receives the trap messages generated by the switch. If no trap manager is defined, no traps will be issued. Cre a te a trap manager by entering the IP address of the station and a community string.
EKI-7657C _Manua l_ed1 76 Figure 3.44: SNMP V3 Configuration interface Group Table Configure SNMP v3 group table. • Security Name (User ID): Assign the u ser name that you have set up in use r table. • Group Name: Set up the group name. • Click Ad d to add context name.

79 Chapter3 Port Base Priority Configure the priority level for each por t. With the drop-down selection item of Prio rity Ty pe above being selected as Port-based, this control item will then be av ailable to set the queuing policy for each port. • Port x: Each port has 4 priority levels— High, Middle, Low, and Lowest—to be chosen.
EKI-7657C _Manua l_ed1 80 IGMP Configuration The Internet Group Management Proto col (IGMP) is an inte rnal protocol of the Inter net Protocol (IP) suite .
81 Chapter3 X-Ring X-Ring provides a faster redund ant recovery than Spanni n g Tree topology. The action is simil ar to STP or RSTP, but the algorithms between them are not the same. In the X-Ring topology, every switch should be enabl ed with X-Ring function and two ports should be assigned as the member ports in the ring.
EKI-7657C _Manua l_ed1 82 Figure 3.47: X-ring interface Note When the X-Ring function enable, user must disa ble the RSTP. The X-Ring function and RSTP function cannot exi s t at the sam e time. Remember to execute the “Save Con figuration” action, otherwise the new configuration will lose when switch power off.
83 Chapter3 LLDP Configuration LLDP (Link Layer Discov ery Protocol) function allows the switch to advertise its information to other nodes on the network and store th e information it discovers. • LLDP Protocol: Disable or enable LLDP function. • LLDP Interval: Set the interval of learning the information time in secon d.
EKI-7657C _Manua l_ed1 84 3.2.4 Security In this section, you can conf igure 802.1x and MAC address table. 802.1X/Radius Configuration 802.1x is an IEEE authentication specification which pr events th.
