Celnet XP is connected to the customer external switch.

An unused port should be located and a mirroring operation should be done to mirror the VLAN of the appropriate RAN, onto the selected destination port.

If the switch supports multiple RNCs then to monitor all these RNCs, as many mirror operations have to be enabled and as many Celnet Data capture modules should be connected.
