The WIM features a pluggable 802.11ax module with WiFi-6 (802.11ax), 2x2 MIMO, two spatial streams, an extended temperature range, and versatile RF coverage with external RP-SMA antenna connectors, including Flexible Antenna Port feature support. For more information on WIM, see Cisco Wi-Fi Interface Module Overview.

The WIM module supports three modes of operation and they are:

• Control and Provisioning of Wireless Access Points (CAPWAP) mode

• Cisco Embedded Wireless Controllers (EWC) mode

• Work Group Bridge (WGB) mode

Starting from Cisco IOS XE Catalyst SD-WAN Release 17.14.1a, configure WIM on Cisco Catalyst IR1800 Rugged Routers using Cisco SD-WAN Manager in CAPWAP and WGB modes. When you configure the WIM in the CAPWAP mode, an external wireless LAN controller manages the module. The WIM module features two radios. In the WGB mode, set up each radio for either wireless access or WGB uplink. To enable Wireless Access, configure one or both radios to Root AP Mode. For WGB uplink, set up one radio to operate in WGB mode.

Note	Configure either or both the radios using the Root AP mode. Only one of the radios can be configured for WGB uplink activity.

The following Cisco Catalyst IR1800 modules are supported by Cisco SD-WAN Manager for configuring WIM:

• Catalyst IR1821-K9

• Catalyst IR1831-K9

• Catalyst IR1833-K9

• Catalyst IR1835-K9

Ensure that the Cisco Catalyst IR1800 devices are running Cisco IOS XE Catalyst SD-WAN Release 17.14.1a or later releases.

• You can't change the login credentials of the WIM using Cisco SD-WAN Manager. For more information see, Default WIM Passwords.

• The Cisco SD-WAN Manager doesn't support changing from the CAPWAP to the WGB mode and the vice-versa. To change modes, see Converting Between Modes.

• You can map a SSID profile to only one radio at a time.

Configure the WIM for different types of WAN connections, such as LTE, MPLS, broadband, or satellite using Cisco SD-WAN Manager and monitor the WIM using real time commands. Configure, manage and deploy both the WIM and WAN connections on Cisco Catalyst IR 1800 Rugged routers using Cisco SD-WAN Manager.

In Cisco SD-WAN Manager, configure WIM on Cisco Catalyst IR1800 Rugged Routers in CAPWAP Mode using the CLI templates. For more information about using CLI templates, see CLI Add-on Feature Templates and CLI Templates.

Note	By default, CLI templates execute commands in global config mode.

1. Create a VLAN interface dedicated only to the layer 2 interface:

   interface Vlan id 

2. Assign the layer 2 interface to the VLAN that you created:

   interface Wlan-GigabitEthernet0/1/4 switchport access vlan id 
   switchport trunk native vlan vlan id 
   switchport mode trunk 

3. Create a DHCP pool for the VLAN:

   Note	Skip this step if you are using an external DHCP server.

   ip dhcp pool vlan id 
   network ip subnet ip mask 
   default-router router ip address 

The following example shows how to create a VLAN interface:

interface Vlan 50,100-200

The following example shows how to assign a layer 2 interface to the created VLAN

interface Wlan-GigabitEthernet0/1/4 switchport access vlan id
switchport access vlan 50,100-200
switchport trunk native vlan vlan 50,100-200
switchport mode trunk

The following example shows how to create a DHCP pool for the VLAN:

ip dhcp pool vlan 50,100-200
network 255.255.255.0 255.0.0
default-router 192.0.2.1

In Cisco SD-WAN Manager, configure WIM on Cisco Catalyst IR1800 Rugged Routers in WGB Mode using the CLI templates. For more information about using CLI templates, see CLI Add-on Feature Templates and CLI Templates.

Note	By default, CLI templates execute commands in global config mode.

1. Enter the wireless-bridge submode:

   wireless-bridge

2. Create a WLAN profile for open authentication:

   ssid-profile ssid profile name ssid ssid name authentication open

3. Create a WLAN profile for WPA2-PSK authentication:

   ssid-profile ssid profile name ssid ssid name authentication auth-type key-management wpa2 secret-key secret key word the unencrypted secret key

4. Assign the WLAN profile to the Wi-Fi radio using the WGB mode:

   dot11Radio 0 or 1 mode wgb ssid-profile ssid profile name

5. Assign the WLAN profile to the Wi-Fi radio using the uWGB mode:

   dot11Radio 0 or 1 mode uwgb client_mac ssid-profile ssid profile name

6. Assign the WLAN profile to the root-AP mode to serve wireless clients:

   dot11Radio 0 or 1 mode root-ap

7. Add a VLAN interface:

   dot11Radio 0 or 1 mode root-ap wlan wlan profile name

8. Enable the radio:

   dot11Radio 0 or 1 enable

9. Assign the operating channel for radio in root-AP mode:

   dot11Radio 0 or 1 channel channel-number width

The following example shows how to configure a clear text password:

wireless-bridge
ssid-profile wlan2 ssid secured_ssid authentication psk key-management wpa2 secret-key 0 12345678
dot11Radio 0 mode wgb ssid-profile test-ssid
dot11Radio 0 mode root-ap
dot11Radio 1 mode root-ap wlan test-wlan
dot11Radio 0 enable
dot11Radio 1 enable
dot11Radio 0 channel 5 10
