Configuration Using the Web-based Utility

Admin > Port Mirroring

Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from one port to a monitoring port. Port mirroring can be used as diagnostic tool and/or a debugging feature. Port mirroring also enables switch performance monitoring.

Network administrators configure port mirroring by selecting a specific port to copy all packets, and different ports from which the packets are copied.

Admin > Port Mirroring

Set the following attributes for port mirroring using the Port Mirroring screen.

Target Port  The port that will mirror the traffic on the source port.

Source Port  The port whose traffic will be monitored.

Type  Allows you to select which traffic to mirror to the target port; receive, transmit, or both.

•RxOnly  Mirror only received traffic. This is the default value.

•TxOnly  Mirror only transmitted traffic.

•Both  Mirror both received and transmitted traffic.

Specify the source port, the traffic type to be mirrored, and the target port, then click Add to List. The mirror session is displayed in the text box.

Admin > Save Configuration

Admin > Save Configuration

The Save Configuration screen allows you to upload Switch configuration files to a TFTP server, or to download saved Switch configuration files from a TFTP server or from your computer via the HTTP interface.

Via TFTP  Select this to upload to or download from a TFTP server. When you select this option, the following fields are displayed.

•UPGRADE  Select this option to restore the Switch configuration from the file located on a TFTP server.

•TFTP Server  Enter the TFTP Server IP Address that contains the source file to download.

•File Name  Enter the name of the configuration file on the TFTP Server.

•BACKUP  To back up the Switch configuration to a TFTP server, enter the TFTP server address.

•TFTP Server  Enter the TFTP Server IP Address to which the configuration file will be saved.

•File Name  Enter the name of the configuration file. The default is StartupCfg.cfg.

Via HTTP  Select this to download a configuration file to the Switch from your computer using the HTTP interface. (HTTP only supports the upgrade operation. You cannot back up the configuration file using HTTP.) When you select this option, the following field is displayed.

•Source File  Enter the name and path of the file or click Browse to locate the configuration file.

Click Save Settings to begin the download or upload.

After you have downloaded the configuration file to the Switch during an upgrade, the configuration file’s settings will not take effect until the system is rebooted.
