OL-7426-02
If Management over Wireless is enabled across the Cisco SWAN, the Network operator can manage the
System across the enabled WLAN using CLI and Telnet (Command Line Interface), http/https (Web
User Interface), and SNMP (Cisco Wireless Control System).
To configure the Cisco SWAN WLANs, refer to Configuring WLANs.
About Access Control ListsAccess Control Lists
The Operating System allows you to define up to 64 Access Control Lists (ACLs), similar to standard
firewall Access Control Lists. Each ACL can have up to 64 Rules (filters).
Operators can use ACLs to control client access to multiple VPN servers within a given WLAN. If all the
clients on a WLAN must access a single VPN server, use the IPSec/VPN Gateway Passthrough setting in
IPSec Passthrough
, WLANs > Edit or Configure <IPaddr> > WLAN > Add From Template section.
After they are defined, the ACLs can be applied to the Management Interface
, the AP-Manager Inter-
face, or any of the Operator-Defined Interfaces.
Refer to Access Control Lists > New
in the Web User Interface Online Help or Creating Access Control
Lists in the Configuring the Cisco Wireless LAN Controllers sections for instructions on how to configure
the Access Control Lists.
About Identity NetworkingIdentity Networking
Cisco Wireless LAN Controllers can have the following parameters applied to all clients associating with
a particular WLAN: QoS, global or Interface-specific DHCP server, Layer 2 and Layer 3 Security Policies,
and default Interface (which includes physical port, VLAN and ACL assignments).
However, the Cisco Wireless LAN Controller can also have individual clients (MAC addresses) override
the preset WLAN parameters by using MAC Filtering or by Allowing AAA Override parameters. This
configuration can be used, for example, to have all company clients log into the corporate WLAN, and
then have clients connect using different QoS, DHCP server, Layer 2 and Layer 3 Security Policies, and
Interface (which includes physical port, VLAN and ACL assignments) settings on a per-MAC Address
basis.
When Network operators configure MAC Filtering for a client, they can assign a different VLAN to the
MAC Address, which can be used to have OS automatically reroute the client to the Management
Interface or any of the Operator-Defined Interfaces, each of which have their own VLAN, ACL, DHCP
server, and physical port assignments. This MAC Filtering can be used as a coarse version of AAA
Override, and normally takes precedence over any AAA (RADIUS or other) Override.
However, when Allow AAA Override
is enabled, the RADIUS (or other AAA) server can alternatively be
configured to return QoS and ACL on a per-MAC Address basis. Allow AAA Override gives the AAA
Override precedence over the MAC Filtering parameters set in the Cisco Wireless LAN Controller; if
there are no AAA Overrides available for a given MAC Address, the OS uses the MAC Filtering parame-
ters already in the Cisco Wireless LAN Controller. This AAA (RADIUS or other) Override can be used as
a finer version of AAA Override, but only takes precedence over MAC Filtering when Allow AAA Override
is enabled.
Note that in all cases, the Override parameters (Operator-Defined Interface and QoS, for example)
must already be defined in the Cisco Wireless LAN Controller configuration.
In all cases, the OS will use QoS and ACL provided by the AAA server or MAC Filtering regardless of the
Layer 2 and/or Layer 3 authentication used.
Also note that the OS will only move clients from the default Cisco SWAN WLAN VLAN to a different
VLAN when configured for MAC filtering, 802.1X, and/or WPA Layer 2 authentication.
To configure the Cisco SWAN WLANs, refer to Configuring WLANs.
