How do I check the ACL on my router?
show run will display the active configuration, including ACLs.
There’s no command to do this in one go.
You’ll need to show run to get the ACL applying and then show access-list to see the actual rules.
The “proper” way to do this without show run is ‘show ip int X/Y’..
What is the difference between ACL and firewall?

Why we use ACL in networking?
There are a variety of reasons we use ACLs. The primary reason is to provide a basic level of security for the network. … ACLs are also used to restrict updates for routing from network peers and can be instrumental in defining flow control for network traffic.
How does an outbound ACL works?
ACL conditions applied on exit work as outbound filter. Inbound ACLs filter the traffic before router makes forward decision. Outbound ACLs filter the traffic after the router makes forward decision. … We can permit certain types of traffic while blocking rest or we can block certain types of traffic while allowing rest.
Which type of ACL is better standard or extended?
A “Standard” ACL allows you to prioritize traffic by the Source IP address. An “Extended” ACL provides greater control over what traffic is prioritized. Extended ACLs can use any or all of the following parameters: Source IP address.
What is a standard ACL?
ACLs are used to filter traffic based on the set of rules defined for the incoming or out going of the network. … Standard Access-list – These are the Access-list which are made using the source IP address only. These ACLs permit or deny the entire protocol suite.

ACL rules require users to pass a set of requirements in order to gain access to particular data. Each ACL rule specifies: The object and operation being secured.

Each rule specifies whether the contents of a given field should be used to permit or deny access to the network, and may apply to one or more of the fields within a packet.
What is ACL filter in router?
Networking Basics: How to Configure Standard ACLs on Cisco Routers. The quick definition: An access control list (ACL) is an ordered list of rules used to filter traffic. … When a packet attempts to enter or leave a router, it’s tested against each rule in the list — from first to last.
