Switch Access Control Lists (ACLs) can be used to filter network traffic based on criteria such as source and destination IP addresses, protocols, and port numbers. Configuring Switch ACLs on a Nebula switch can provide additional security to the network by blocking unauthorized traffic. In this post, we will guide you through the steps to configure Switch ACLs on a Nebula switch.

Please note that GS1350 and GS1915 do not support this feature.

  1. Site-wideConfigureSwitchesACL,

2. Click on "Create ACL" to define a new ACL rule.

3. Give your ACL rule a name to easily identify its purpose.

4. Specify the desired rule criteria, such as Source IP, Destination IP, Protocol, and Port.

5. Determine the action to be taken for the matching traffic, whether it should be allowed or denied.

Verification and Noted:
To verify the effectiveness of your ACL configuration, follow these steps:

  1. Generate traffic that matches the criteria defined in your ACL rules.
  2. Monitor the traffic to ensure that the ACL is correctly allowing or denying the specified traffic.
  3. Make adjustments to the ACL rules if needed to achieve the desired network access control.

Note: It is essential to carefully plan and test your ACL rules before applying them to a production environment. Improperly configured ACLs may lead to unintended consequences, such as blocking legitimate traffic. Regularly review and update your ACLs to align with your network security policies.
