Configuring Access Control Lists 589
Please note the following additional limitations on ingress and egress ACLs:
• You can configure mirror or redirect attributes for a given ACL rule, but
not both.
•The
Dell Networking series switches support a limited number of counter
resources, so it may not be possible to log every ACL rule. You can define
an ACL with any number of logging rules, but the number of rules that are
actually logged cannot be determined until the ACL is applied to an
interface. Furthermore, hardware counters that become available after an
ACL is applied are not retroactively assigned to rules that were unable to
be logged (the ACL must be disassociated from the interface and then re-
associated). Rules that are unable to be logged are still active in the ACL
for purposes of permitting or denying a matching packet. If console logging
is enabled and the severity is set to a numeric ally lower severity than the
console severity setting, a log entry may appear on the screen.
