Extended Access Control List (ACL) - Port Operators
When working with Extended Access Control Lists (ACL), we can specify TCP and UDP port numbers to permit or deny. To filter the traffic based on TCP or UDP port numbers, we can use an operator. The operator is used to match the port number or numbers in Access Control Lists. The following table lists important Extended Access Control Lists (ACL) operators.
