xStack® DGS-3620 Series Managed Switch Web UI Reference Guide Configuration File Backup/Restore This screen is used to upgrade configuration files from the Commander Switch to the Member Switch using a TFTP server. Member Switches will be listed in the table and will be specified by ID, Port (port on the CS where the MS resides), MAC Address, Model Name and Firmware Version. To update the configuration file, enter the Server IP Address where the file resides and enter the Path/Filename of the configuration file. Click Restore to initiate the file transfer from a TFTP server to the Switch. Click Backup to backup the configuration file to a TFTP server. To view the following window, click Management > Single IP Management > Configuration File Backup/Restore, as show below: Figure 3-34 Configuration File Backup/Restore window Upload Log File The following window is used to upload log files from SIM member switches to a specified PC. To upload a log file, enter the Server IP address of the SIM member switch and then enter a Path\Filename on your PC where you wish to save this file. Click Upload to initiate the file transfer. To view the following window, click Management > Single IP Management > Upload Log File, as show below: Figure 3-35 Upload Log File window SNMP Settings Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and monitoring network devices. SNMP enables network management stations to read and modify the settings of gateways, routers, switches, and other network devices. Use SNMP to configure system features for proper operation, monitor performance and detect potential problems in the Switch, switch group or network. Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device. A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage the device. These objects are defined in a Management Information Base (MIB), which provides a standard presentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the network. The Switch supports the SNMP versions 1, 2c, and 3. The three versions of SNMP vary in the level of security provided between the management station and the network device. In SNMP v.1 and v.2, user authentication is accomplished using 'community strings', which function like passwords. The remote user SNMP application and the Switch SNMP must use the same community string. SNMP packets from any station that has not been authenticated are ignored (dropped). The default community strings for the Switch used for SNMP v.1 and v.2 management access are: • public - Allows authorized management stations to retrieve MIB objects. 49
