Explanation & Hint:
- ACL (Access Control List): This is a series of commands that control whether a device forwards or drops packets. ACLs are used to filter traffic based on a set of rules defined by the network administrator to increase security by restricting the flow of packets allowed to enter or exit network interfaces.
- SNMP (Simple Network Management Protocol): This allows administrators to manage network devices. SNMP is used for collecting information from, and configuring, network devices, such as servers, printers, hubs, switches, and routers on an Internet Protocol (IP) network.
- NetFlow: This provides statistics on packets flowing through a Cisco router or multilayer switch. NetFlow is a network protocol developed by Cisco for collecting IP traffic information and monitoring network traffic.
- Port Mirroring: This allows a switch to make duplicate copies of traffic that is sent to a traffic analyzer. Port mirroring is used on a network switch to send a copy of network packets seen on one switch port (or an entire VLAN) to a network monitoring connection on another switch port.
