[. . . ] 1 FCC Warning This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limitations are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. [. . . ] This parameter specifies the path costs of the ports that the switch uses to determine which ports are the forwarding ports. The range is 1-65535, and the default value is bases on the IEEE 802. 1D specifications: 10Mb/s = 50-600, 100Mb/s = 10-60, 1000Mb/s = 3-10 5. 4. 9 Port Sniffer The port sniffer is a tool for monitoring traffic in switched networks. Traffic going in or out of monitored ports will be duplicated into a sniffer port. Sniffer Mode: Press Spacebar to set the sniffer mode to: Disable \Rx \Tx \Both. Monitoring Port: The sniffer port can be used to monitor port traffic. You can connect the sniffer port to a LAN analyzer or NetXRay. 47 3. User can choose which port that they want to monitor in only one sniffer mode. If you want to disable the function, you must select "None" in the "Analysis Port" category. 48 5. 4. 10 SNMP/Trap Manager Any network management platform that is running the Simple Network Management Protocol (SNMP) can manage the switch, provided the Management Information Base (MIB) is installed correctly on the management station. SNMP is a protocol that governs the transfer of information between management station and agent. System Options: You can define a name, location, and contact person for the switch. Fill in the system options data, and then click Apply to update the changes on this page. Contact: Enter the name of a person or organization. 2. Community sSrings: serve as passwords and can be entered as one of the following: RO: Read-only - enables requests accompanied by this string to display MIB-object information. RW: Read-write - enables requests accompanied by this string to display MIB-object information and to set MIB objects. 49 3. Trap Managers: A trap manager is a management station that receives traps, which are the system alerts generated by the switch. Create a trap manager by entering the IP address of the station and a community string. 5. 4. 11 Security Manager On this page, you can change the user name and password as follows: 1. Click Apply. 50 5. 4. 12 802. 1x Configuration System Configuration 802. 1x makes use of the physical access characteristics of IEEE 802 LAN infrastructures in order to provide a means of authenticating and authorizing devices attached to a LAN port that has point-to-point connection characteristics, and of preventing access to that port in cases in which the authentication and authorization process fails. To enable 802. 1x, go to Administrator > Switch Settings > Advanced. After enabling 802. 1x, proceed to the "802. 1x Configuration" section to fill in the authentication server information. Radius Server IP Address: The IP address of the authentication server. Server Port: The UDP port number used by the authentication server to authenticate. Accounting Port: The UDP port number used by the authentication server to retrieve accounting information. Shared Key: A key shared between this switch and the authentication server. NAS, Identifier: A string used to identify this switch. 51 Per Port Configuration In this page, you can select a specific port and configure the authorization state. You can select from a list of four authorization states for each port: Fu: Forces a specific port to be unauthorized. [. . . ] Serial number: Displays the serial number assigned by the manufacturer. Module 1 information: Displays the information saved in EEPROM of module 1. Module 2 information: Displays the information saved in EEPROM of module 2. 119 7. 5 Reboot Switch 7. 5. 1 Default Resets the switch to its default configuration. For default settings, please see Section 2-4-14. 7. 5. 2 Restart Reboot the switch in software reset. 120 7. 6 TFTP Firmware Update This page provides you with the option to update the firmware, restore the EEPROM values, or upload current EEPROM values. 121 7. 6. 1 TFTP Firmware Update This page allows you to use TFTP to update the firmware. 1.
