config interface acl
Syntax Description
Usage Guidelines
For a Cisco 2100 Series Wireless LAN Controller, you must configure a preauthentication ACL on the wireless LAN for the external web server. This ACL should then be set as a wireless LAN preauthentication ACL under Web Policy. However, you do not need to configure any preauthentication ACL for Cisco 4400 Series Wireless LAN Controllers.
config interface address
config interface address { ap-manager IP_address netmask gateway | management IP_address netmask gateway | service-port IP_address netmask | virtual IP_address | dynamic-interface IP_address dynamic_interface netmask gateway | redundancy-management IP_address peer-redundancy-management IP_address }
Syntax Description
Usage Guidelines
For Cisco 5500 Series Controllers, you are not required to configure an AP-manager interface. The management interface acts like an AP-manager interface by default.
Usage Guidelines
Ensure that the management interfaces of both controllers are in the same subnet. Ensure that the Redundant Management IP address for both controllers is the same. Likewise, ensure that the Peer Redundant Management IP address for both the controllers is the same.
Examples
This example shows how to configure an access point manager interface with IP address 209.165.201.31, network mask 255.255.0.0, and gateway address 209.165.201.30:
> config interface address ap-manager 209.165.201.31 255.255.0.0 209.165.201.30This example shows how to configure a redundancy management interface on the controller:
> config interface address redundancy-management 209.4.120.5 peer-redundancy-management 209.4.120.6This example shows how to configure a virtual interface:
> config interface address virtual 1.1.1.1config interface address peer-redundancy-management
To configure the management interface IP address of the peer controller, use the config interface address peer-redundancy-management command.
Syntax Description
Usage Guidelines
You can use this command to check the Active-Standby reachability when the keep-alive fails.
config interface address redundancy-management
To configure the management interface IP address of active and standby controllers, use the config interface address redundancy-management command.
Syntax Description
IP_address Management interface IP address of the active controller.
peer-redundancy-management Specifies the management interface IP address of the peer controller.
IP_address2 Management interface IP address of the peer controller.
Usage Guidelines
You can use this command to check the Active-Standby reachability when the keep-alive fails and to configure an alias IP for the management port of the controller. Both the IP addresses must be in the same subnet.
config interface ap-manager
To enable or disable access point manager features on the management or dynamic interface, use the config interface ap-manager command.
Syntax Description
Enables access point manager features on a dynamic interface.
Disables access point manager features on a dynamic interface.
Usage Guidelines
Use the management option to enable or disable dynamic AP management for the management interface. For Cisco 5500 Series Controllers, the management interface acts like an AP-manager interface by default. If desired, you can disable the management interface as an AP-manager interface and create another dynamic interface as an AP manager.
When you enable this feature for a dynamic interface, the dynamic interface is configured as an AP-manager interface (only one AP-manager interface is allowed per physical port). A dynamic interface that is marked as an AP-manager interface cannot be used as a WLAN interface.
config interface create
config interface delete
config interface dhcp
config interface dhcp { ap-manager [ primary dhcp_server secondary dhcp_server | option-82 [ enable | disable] ] | management [ primary dhcp_server secondary dhcp_server | option-82 [ enable | disable] ] | service-port { enable | disable} | dynamic-interfaceinterface_name [ primary dhcp_server secondary dhcp_server | option-82 [ enable | disable] | proxy-mode { enable | disable | global}]}
Syntax Description
Examples
This example shows how to configure ap-manager server with the primary DHCP server 10.21.15.01 and secondary DHCP server 10.21.15.25:
> config interface dhcp ap-manager server-1 10.21.15.01 server-2 10.21.15.25This example shows how to configure DHCP option 82 on the ap-manager:
> config interface dhcp ap-manager option-82 enableThis example shows how to enable the DHCP for the out-of-band service port:
> config interface dhcp service-port enableconfig interface address
config interface address { dynamic-interface dynamic_interface netmask gateway | management | redundancy-management IP_address peer-redundancy-management | service-port netmask | virtual} IP_address

Usage Guidelines
Ensure that the management interfaces of both controllers are in the same subnet. Ensure that the redundant management IP address for both controllers is the same and that the peer redundant management IP address for both the controllers is the same.
config interface guest-lan
config interface hostname
To configure the Domain Name System (DNS) hostname of the virtual gateway interface, use the config interface hostname command.
Syntax Description
config interface nasid
To configure the Network Access Server identifier (NAS-ID) for the interface, use the config interface nasid command.
Syntax Description
NAS-ID Network Access Server identifier (NAS-ID) for the interface. The NAS-ID is sent to the RADIUS server by the controller (as a RADIUS client) using the authentication request, which is used to classify users to different groups. You can enter up to 32 alphanumeric characters.
Beginning in Release 7.4 and later releases, you can configure the NAS-ID on the interface, WLAN, or an access point group. The order of priority is AP group NAS-ID > WLAN NAS-ID > Interface NAS-ID.
none Configures the controller system name as the NAS-ID.
interface_name Interface name up to 32 alphanumeric characters.
config interface nat-address
To deploy your Cisco 5500 Series Controller behind a router or other gateway device that is using one-to-one mapping network address translation (NAT), use the config interface nat-address command.
config interface nat-address { management | dynamic-interface interface_name} {{ enable | disable} | { set public_IP_address}}
Syntax Description
Usage Guidelines
These NAT commands can be used only on Cisco 5500 Series Controllers and only if the management interface is configured for dynamic AP management.
These commands are supported for use only with one-to-one-mapping NAT, where each private client has a direct and fixed mapping to a global address. They do not support one-to-many NAT, which uses source port mapping to enable a group of clients to be represented by a single IP address.
config interface port
To map a physical port to the interface (if a link aggregation trunk is not configured), use the config interface port command.
config interface port { management | interface_name | redundancy-management} primary_port [ secondary_port]
Syntax Description
Usage Guidelines
You can use the management option for all controllers except the Cisco 5500 Series Controllers.
config interface quarantine vlan
config interface vlan
config interface group mdns-profile
