Copying An Ipv6 Acl - 3Com 4500G Family Configuration Manual

You can only modify the existing rules of an ACL that uses the match order of config. When
modifying a rule of such an ACL, you may choose to change just some of the settings, in which
case the other settings remain the same.
You cannot create a rule with, or modify a rule to have, the same permit/deny statement as an
existing rule in the ACL.
When the ACL match order is auto, a newly created rule will be inserted among the existing rules in
the depth-first match order. Note that the IDs of the rules still remain the same.
You can modify the match order of an IPv6 ACL with the acl ipv6 number acl6-number [ name
acl6-name ] match-order { auto | config } command, but only when the ACL does not contain any
rules.
The rule specified in the rule comment command must already exist.
Configuration Example
# Configure IPv6 ACL 3000 to permit TCP packets with the source address of 2030:5060::9050/64.
<Sysname> system-view
[Sysname] acl ipv6 number 3000
[Sysname-acl6-adv-3000] rule permit tcp source 2030:5060::9050/64
# Verify the configuration.
[Sysname-acl6-adv-3000] display acl ipv6 3000
Advanced IPv6 ACL
ACL's step is 5
rule 0 permit tcp source 2030:5060::9050/64 (5 times matched)

Copying an IPv6 ACL

This feature allows you to copy an existing IPv6 ACL to generate a new one, which is of the same type
and has the same match order, rules, rule numbering step, and descriptions as the source IPv6 ACL.
Configuration Prerequisites
Make sure that the source IPv6 ACL exists while the destination IPv6 ACL does not.
Configuration Procedure
Follow these steps to copy an IPv6 ACL:
To do...
Enter system view
3000, named -none-, 1 rule,
Use the command...
