Access Control Lists (ACLs)
Terminology
identifier: The term used in ACL syntax statements to represent either the
name or number by which the ACL can be accessed. See also name-str.
Note: RADIUS-assigned ACLs are identified by client authentication data
and do not use the identifiers described in this chapter.
Implicit Deny: If the switch finds no matches between an IP packet and the
configured criteria in an applicable ACL, then the switch denies (drops)
the packet with an implicit deny any function (for standard ACLs) or an
implicit deny ip any any function (for extended ACLs). You can preempt
the Implicit Deny in a given ACL by configuring a permit any (standard) or
permit IP any any (extended) as the last explicit ACE in the ACL. Doing so
permits any IP packet that is not explicitly permitted or denied by other
ACEs configured sequentially earlier in the ACL. Unless otherwise noted,
Implicit Deny refers to the “deny” function enforced by both standard and
extended ACLs.
Inbound Traffic: For the purpose of defining where the switch applies ACLs
to filter IP traffic, inbound traffic is any IP packet that meets one of the
following criteria:
Routed ACL (RACL): Inbound traffic is any IP packet entering the
switch on a VLAN interface (or a subnet in a multinetted VLAN) with
a destination IP address (DA) that is for any of the following:
an external device on a different VLAN or subnet than the inter-
face on which it arrived
an IP address configured on the switch itself
a broadcast
Note that, except for IP traffic addressed to the switch itself, and
outbound IP traffic generated by the switch, routing must be config-
ured on the switch to enable support for RACL applications.
VLAN ACL (VACL): Inbound traffic is any IP packet entering the
switch on a VLAN interface (or a subnet in a multinetted VLAN).
Static Port ACL: Inbound traffic is any IP packet entering the switch
on the port.
Dynamic Port ACL: Where a RADIUS server has authenticated a client
and assigned an ACL to the port to filter the client’s IP traffic, inbound
traffic is any IP packet entering the switch from that client.
name-str: The term used in extended ACL syntax statements to represent the
“name string”; the alphanumeric string used to identify the ACL. See also
identifier and ACL-ID.
