Remote Port Mirroring
Remote Port Mirroring is supported on the MXL Switch platform.
While local port monitoring allows you to monitor traffic from one or more source ports by directing it to
a destination port on the same switch/router, remote port mirroring allows you to monitor Layer 2 and
Layer 3 ingress or egress or both ingressing or egressing traffic on multiple source ports on different
switches and forward the mirrored traffic to multiple destination ports on different switches. Remote port
