Extreme Networks switches feature support for the routing and filtering of network traffic based on parameters configured by the network administrator. Access Control Lists (ACL) apply traffic control policies that can permit or deny forwarding traffic to or from specified areas of the network. If network traffic is not forwarded or filtered correctly, the ACL configuration is one of the first configurations that should be verified. Use the Extreme Networks switch command line to access and verify ACL configuration.
