2. Create an IPv6 basic ACL
view and enter its view.
acl ipv6 number acl-number
[ name acl-name ] [ match-order
{ auto | config } ]
By default, no ACL exists.
IPv6 basic ACLs are numbered in
the range of 2000 to 2999.
You can use the acl ipv6 name
acl-name command to enter the
view of a named ACL.
3. (Optional.) Configure a
description for the IPv6 basic
ACL.
description text
By default, an IPv6 basic ACL has
no ACL description.
4. (Optional.) Set the rule
numbering step.
step step-value The default setting is 5.
5. Create or edit a rule.
rule [ rule-id ] { deny | permit }
[ counting | fragment | logging |
routing [ type routing-type ] |
source { source-address
source-prefix |
source-address/source-prefix |
any } | time-range
time-range-name | vpn-instance
vpn-instance-name ] *
By default, an IPv6 basic ACL does
not contain any rule.
The logging keyword takes effect
only when the module (for
example, packet filtering) that uses
the ACL supports logging.
When an ACL is used for QoS
traffic classification or packet
filtering, the ACL does not
supported the vpn-instance or
fragment keyword.
6. (Optional.) Add or edit a rule
comment.
rule rule-id comment text
By default, no rule comments are
configured.
Configuring an advanced ACL
This section describes procedures for configuring IPv4 and IPv6 advanced ACLs.
Configuring an IPv4 advanced ACL
IPv4 advanced ACLs match packets based on source IP addresses, destination IP addresses, packet
priorities, protocols over IP, and other protocol header information, such as TCP/UDP source and
destination port numbers, TCP flags, ICMP message types, and ICMP message codes.
Compared to IPv4 basic ACLs, IPv4 advanced ACLs allow more flexible and accurate filtering.
To configure an IPv4 advanced ACL:
