1. Configure port security on the switch port: Port security enables you to limit and identify MAC addresses of the devices connected to a specific switch port.
2. Use SPAN (Switched Port Analyzer): SPAN enables you to forward packets seen on one port to another for monitoring purposes.
3. Use NetFlow: NetFlow is a Cisco proprietary protocol that can be used to monitor and analyze network traffic.
4. Use SNMP: Simple Network Management Protocol (SNMP) enables you to query the switches with MIBs (Management Information Base) to get traffic statistics.
