•
port – Sets the valid port number
•
{destination/destination-mask | host destination |
any} – Defines the destination host IP address or

•
[operator destination-port] – Specifies the
destination port
•
[log] – Generates log messages when the packet
coming from the interface matches the ACL entry. Log
