Configuring a Basic ACL
A basic ACL defines rules to filter packets.
Usage Scenario
Figure 1 Configuring a basic ACL
Interfaces 1 through 2 in this example are GE 0/1/0, GE 0/1/8, respectively.
As shown in Figure 1, a basic ACL is created on Device A to allow Device A to permit all packets sent from Network A to the Internet and deny all packets sent from Network B and Network C to the Internet.
- (Optional) Creating a Validity Period for an ACL Rule
- You can create a validity period for an ACL rule to control network traffic in a specified period.
- Creating a Basic ACL
- You can create a basic ACL and configure parameters for the ACL.
- Configuring a Basic ACL Rule
- Basic ACL rules are defined based on whether the packets are the first fragments, packets' source IP addresses, and VPN instances to filter packets.
- Applying a Basic ACL
- Basic ACLs can be used in device management, routing policies, multicast packet filtering, and QoS services.
- Verifying the Configuration of a Basic ACL
- After configuring a basic ACL, verify the configuration.
