interface, the Implicit Deny function does not operate, and
the ACL has no effect on traffic.
Monitoring shared resources. Applied ACLs share internal switch resources with several
other features. However, if the internal resources become
fully subscribed, additional ACLs cannot be applied until
the necessary resources are released from other applications.
For information on determining current resource availability
and usage, see appendix, "Monitoring Resources" in the
latest HP Switch Software Management and Configuration
Guide for your switch. See also appendix "Scalability and
System Maximums" in the same guide.
Replacing or adding to an active IPv6
ACL policy.
If you assign an IPv6 ACL to an interface and subsequently
add or replace ACEs in that ACL, each new ACE becomes
active when you enter it. If the ACL is configured on multiple
interfaces when the change occurs, then switch resources
must accommodate all applications of the ACL. If there are
insufficient resources to accommodate an ACL application
affected by the change, the change is not applied to any
of the interfaces and the previous version of the ACL remains
in effect. See “Monitoring shared resources” (page 108).
"Strict" IPv6 TCP and UDP. When the IPv6 ACL configuration includes TCP or UDP
options, the switch operates in "strict" TCP and UDP mode
for increased control and the switch compares all IPv6 TCP
and UDP packets against the IPv6 ACLs.
Unable to delete an empty ACL in the
running configuration.
The no vlan <vid> ipv6 access-group
<name-str> vlancommand does not delete the named
ACL if the ACL is currently assigned to an interface.
Unable to delete an ACL in the running configuration
Attempting to delete an ACL currently assigned to an interface removes all configured ACEs from
the ACL but leaves an "empty" ACL in the configuration. To delete an ACL currently assigned to
an interface, do the following:
In the interface context, use the no ipv6 access-group command to remove the ACL from the
interface.
Use the no ipv6 access-list <name-str> command to delete the ACL.
