ACL Groups
To
assist
in
organizing
multiple
ACLs
and
assigning
them
to
ports,
you
can
place
ACLs
into
ACL
Groups,
thereby
defining
complex
traffic
profiles.
ACLs
and
ACL
Groups
can
then
be
assigned
on
a
per
‐
port
basis.
Any
specific
ACL
can
be
assigned
to
multiple
ACL
Groups,
and
any
ACL
or
ACL
Group
can
be
assigned
to
multiple
ports.
If,
as
part
of
multiple
ACL
Groups,
a
specific
ACL
is
assigned
to
a
port
multiple
times,
only
one
instance
is
used.
The
redundant
entries
are
ignored.
Individual
ACLs
The
NE2552E
supports
up
to
256
ACLs.
Each
ACL
defines
one
filter
rule
for
matching
traffic
criteria.
Each
filter
rule
can
also
include
an
action
(permit
or
deny
the
packet).
For
example:
Access
Control
List
Groups
An
Access
Control
List
Group
(ACL
Group)
is
a
collection
of
ACLs.
For
example:
ACL
Groups
organize
ACLs
into
traffic
profiles
that
can
be
more
easily
assigned
to
ports.
The
NE2552E
supports
up
to
256
ACL
Groups.
Note:
ACL
Groups
are
used
for
convenience
in
assigning
multiple
ACLs
to
ports.
ACL
Groups
have
no
effect
on
the
order
in
which
ACLs
are
applied
(see
).
All
ACLs
assigned
to
the
port
(whether
individually
assigned
or
part
of
an
ACL
Group)
are
considered
as
individual
ACLs
for
the
purposes
of
determining
their
order
of
precedence.
Assigning ACL Groups to a Port
To
assign
an
ACL
Group
to
a
port,
use
the
following
commands:
ACL
1:
VLAN
=
1
SIP
=
10.10.10.1
(255.255.255.0)
Action
=
permit
ACL Group 1
ACL
1:
VLAN
=
1
SIP
=
10.10.10.1
(255.255.255.0)
Action
=
permit
ACL
2:
VLAN
=
2
SIP
=
10.10.10.2
(255.255.255.0)
Action
=
deny
ACL
3:
Priority
=
7
DIP
=
10.10.10.3
(255.255.255.0)
Action
=
permit
