Port mirroring Port mirroring lets you select the network traffic of specific switch ports for analysis by a network analyzer. For each port mirroring configuration (the switch supports up to four), you can select many switch ports as source ports but only a single switch port as the destination port. For each port mirroring configuration, you can configure how traffic is mirrored on a source port by selecting packets that are received, transmitted, or both. You can also apply an IP ACL or MAC ACL to filter the traffic that is being mirrored. A packet that is copied to the destination port is in the same format as the original packet. 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. Monitor the Switch and Network 718 Main User Manual
