FS728TP Smart Switch Software Administration Manual Port Mirroring The page under the Mirroring link allows you to view and configure port mirroring on the system. Multiple Port Mirroring Port mirroring selects the network traffic for analysis by a network analyzer. This is done for specific ports of the switch. As such, many switch ports are configured as source ports and one switch port is configured as a destination port. Packets that are received and transmitted by the source port are be mirrored to the destination port. The packet that is copied to the destination port is in the same format as the original packet on the wire. This means that if the mirror is copying a received packet, the copied packet is VLAN tagged or untagged as it was received on the source port. If the mirror is copying a transmitted packet, the copied packet is VLAN tagged or untagged as it is being transmitted on the source port. Use the Multiple Port Mirroring page to define port mirroring sessions. To access the Multiple Port Mirroring page, click Monitoring Port Mirroring. To configure Port Mirroring: 1. Select the check box next to a port to configure it as a source port. 2. In the Destination Port field, specify the port to which port traffic is be copied. Use the e1, e2,...format to specify the port. You can configure only one destination port on the system. 3. From the Session Mode menu, select the mode for port mirroring on the selected port: • Enable. Multiple Port Mirroring is active on the selected port. • Disable. Port mirroring is not active on the selected port, but the mirroring information is retained. Chapter 6: Monitoring the System | 211
