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 monitored traffic with the reserved L2 VLAN. Remote port monitoring supports monitoring sessions where multiple source and destination ports distribute across multiple network devices.
