Rule (For Advanced Acls) - 3Com 5500-EI PWR Reference Manual

be the greatest rule number plus one. If the current greatest rule number is 65534, however, the
system will display an error message and you need to specify a number for the rule.
The content of a modified or created rule cannot be identical with the content of any existing rule;
otherwise the rule modification or creation will fail, and the system prompts that the rule already
exists.
With the auto match order specified, the newly created rules will be inserted in the existent ones by
depth-first principle, but the numbers of the existent rules are unaltered.
Examples
