Configuring TCP and UDP traffic in IPv6 ACLs
An ACE designed to permit or deny TCP or UDP traffic can optionally include port number criteria
for either the source, the destination, or both. Use of TCP criteria also allows the established
option for controlling TCP connection traffic.
TCP Syntax:
[ deny | permit ] tcp
SA [ comparison-operator tcp-src-port ]
DA [ comparison-operator tcp-dest-port ]
[ established ]
[ ack ] [ fin ] [ rst ] [ syn ]
UDP Syntax:
[ deny | permit ] udp
SA [ comparison-operator udp-src-port ]
DA [ comparison-operator udp-dest-port ]
In an IPv6 ACL using either tcp or udp as the IP packet protocol type, you can
optionally apply comparison operators specifying TCP or UDP source and/or
destination port numbers or ranges of numbers to further define the criteria for a
match. For example:
