Remote port monitoring on VLT

In a network, devices you configure with peer VLT nodes are considered as a single device. You can apply remote port monitoring (RPM) on the VLT devices in a network.

In a failover case, the monitored traffic reaches the packet analyzer connected to the top-of-rack (ToR) through the VLT interconnect link.

RPM on VLT scenarios

Consider a simple VLT setup where two VLT devices are connected using VLTi and a top-of-rack switch is connected to both the VLT peers using VLT port-channels in a ring topology. In this setup, the following table describes the possible scenarios when you use RPM to mirror traffic.
