Required
By default IPv6 advanced ACL
does not contain any rule.
To create or edit multiple rules,
repeat this step.
Note that if the ACL is to be
referenced by a QoS policy for
traffic classification, the logging
and fragment keywords are not
supported and the operator
argument cannot be:
z
neq, if the policy is for the
inbound traffic,
z
gt, lt, neq or range, if the
policy is for the outbound
traffic.

rule rule-id comment text
Optional
By default, an IPv6 ACL rule has
no rule description.
Note that:
z
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.
z
You cannot create a rule with, or modify a rule to have, the same permit/deny statement as an
existing rule in the ACL.
z
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 it does not contain any rules.
Configuring an Ethernet Frame Header ACL
Ethernet frame header ACLs, also called Layer 2 ACLs, match packets based on Layer 2 protocol
header fields such as source MAC address, destination MAC address, 802.1p priority (VLAN priority),
and link layer protocol type.
