You can edit ACL rules only when the match order is config.
To view the existing IPv6 basic and advanced ACL rules, use the display acl ipv6 all command.
The rule ID is required in the undo rule rule-id command.
If you do not specify optional parameters, the undo rule rule-id command deletes the entire rule. If
you specify optional parameters, the undo rule rule-id command deletes the specified attributes.
The undo rule { deny | permit } command can only be used to delete the entire rule. You must
specify all the attributes of the rule for the command.

fe80:5060::/96 destination-port eq 80
# Create IPv6 advanced ACL rules to permit all IPv6 packets but the ICMPv6 packets destined for
FE80:5060:1001::/48.
