Configuring an Interface ACL
An interface ACL defines rules to filter packets.
Usage Scenario
Figure 1 Configuring an interface ACL
Interfaces 1 through 2 in this example are GE 0/1/0, GE 0/1/8, respectively.
As shown in Figure 1, an ACL based on GE 0/1/0 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 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 an Interface ACL
- You can create an interface ACL and configure parameters for the ACL.
- Configuring an Interface-based ACL Rule
- Interface-based ACL rules are defined based on packets' inbound interfaces to filter packets.
- Verifying the Configuration of an Interface ACL
- After configuring an interface ACL, verify the configuration.
