Remote port monitoring

Remote port monitoring monitors ingress traffic, egress traffic, or both, on multiple source ports of multiple devices.

It forwards the monitored traffic to multiple destination ports on different remote devices. Remote port monitoring helps network administrators monitor and analyze traffic to troubleshoot network problems.

In a remote port monitoring session, monitored traffic is tagged with a VLAN ID and switched on a user-defined, nonroutable L2 VLAN. The VLAN is reserved to carry only monitored traffic, which is forwarded on all egress ports of the VLAN. You must configure each intermediate switch that participates in transporting the monitored traffic with the reserved L2 VLAN.

In the following diagram, the source port (Eth 1/1/26:1) is on one switch, and destination port (Eth 1/1/26:1) is on the other switch. The source port forwards the packet copy to the destination port through the uplink connection. This enables data monitoring and analysis across devices.
