Packet Tracer ACL (Access Control List) is a feature in the Cisco Packet Tracer software that allows network administrators to control network traffic by filtering packets based on certain criteria. ACLs can be applied to routers, switches, and firewalls to restrict or permit traffic entering or exiting a network.
Packet Tracer ACLs use a set of rules to determine which packets are allowed to pass through the network and which packets are not. These rules can be based on a wide range of criteria such as source and destination IP addresses, protocols, port numbers, and more.
To set up an ACL in Packet Tracer, you need to follow these steps:
1. Open Packet Tracer and create a network topology.
2. Add a router or switch to the topology and configure its interfaces.
3. Access the router or switch CLI and enter the privilege EXEC mode.
4. Define the ACL by specifying the permit or deny conditions based on the criteria you want to use.
5. Apply the ACL to the appropriate interface using the access-group command.
Once you have set up a Packet Tracer ACL, you can test it by sending packets through the network and observing which packets are allowed or denied based on the ACL rules. This feature is useful for maintaining network security and controlling network bandwidth usage.
