Port Rules in Port Mirroring
The following table shows the rule for a port in remote port mirroring. For example, a port on the
source device can be a mirroring port in both RMirror VLAN 1 and RMirror VLAN 2. But when the
port is the source device’s mirroring port in RMirror VLAN 1, it cannot be the reflector port or
monitor port in another RMirror VLAN.
The following table shows the rule for a port used in both local port mirroring and remote port
mirroring. For example, the RMirror mirroring port on the source device can also be used as the
mirroring port in local port mirroring. But it cannot be the monitor port in local port mirroring.
