Step Command Remarks
1. Enter system view. system-view N/A
2. Create an IPv4
advanced ACL and
enter its view.
acl number acl-number [ name
acl-name ] [ match-order { auto |
config } ]
By default, no ACL exists.
IPv4 advanced ACLs are numbered in the
range of 3000 to 3999.
You can use the acl name acl-name
command to enter the view of a named ACL.
3. Configure a
description for the
IPv4 advanced ACL.
description text
Optional.
By default, an IPv4 advanced ACL has no
ACL description.
4. Set the rule
numbering step.
step step-value
Optional.
The default setting is 5.
5. Create or edit a rule.
rule [ rule-id ] { deny | permit }
protocol [ { { ack ack-value | fin
fin-value | psh psh-value | rst
rst-value | syn syn-value | urg
urg-value } * | established } |
counting | destination
{ dest-address dest-wildcard |
any } | destination-port operator
port1 [ port2 ] | dscp dscp |
fragment | icmp-type { icmp-type
[ icmp-code ] | icmp-message } |
logging | precedence
precedence | reflective | source
{ source-address source-wildcard
| any } | source-port operator
port1 [ port2 ] | time-range
time-range-name | tos tos |
vpn-instance vpn-instance-name ]
*
By default, an IPv4 advanced ACL does not
contain any rule.
The logging keyword takes effect only when
the module using the ACL supports logging.
The device does not support the counting
keyword.
6. Add or edit a rule
comment.
rule rule-id comment text
Optional.
By default, no rule comments are
configured.
7. Add or edit a rule
range remark.
rule [ rule-id ] remark text
Optional.
By default, no rule range remarks are
configured.
Configuring an IPv6 advanced ACL
IPv6 advanced ACLs match packets based on the source IPv6 addresses, destination IPv6 addresses,
packet priorities, protocols carried over IPv6, and other protocol header fields such as the TCP/UDP
source port number, TCP/UDP destination port number, ICMPv6 message type, and ICMPv6 message
code.
Compared to IPv6 basic ACLs, IPv6 advanced ACLs allow more flexible and accurate filtering.
To configure an IPv6 advanced ACL:
