Introduction

Overview of the Access Point

The Cisco Catalyst IW9167E Heavy Duty Access Point provides reliable wireless connectivity for mission-critical applications in a state-of-the art platform. It can operate as Cisco Catalyst Wi-Fi (CAPWAP) mode or Cisco Ultra-Reliable Wireless Backhaul (Cisco URWB) mode starting from IOS XE Cupertino 17.9.3 Software Release. The IW9167EH access point has the flexibility to change the operating mode from Wi-Fi to Cisco URWB, and vice versa.

Starting from Cisco IOS XE Dublin 17.11.1, Workgroup Bridge (WGB) and Universal WGB (uWGB) are supported on the Cisco Catalyst IW9167E Heavy Duty Access Points.

This document covers configuration of CAPWAP mode and WGB/uWGB mode specific to the IW9167EH access points.

For CAPWAP mode, the access points can operate in the following modes:

  • Local

  • Flexconnect

  • Bridge

  • Flexconnect + Bridge

  • Sniffer

  • Monitor

  • Site survey

Determine Image on IW9167EH

Software images are stored under different folders on the same partition on IW9167EH.

You need to choose the image to boot up with according to the mode your AP is runnning, CAPWAP, Cisco URWB, or WGB/uWGB. The following table provides the software images of each mode:

Table 1. IW9167EH Software Images

IW9167EH Mode

Software Image

CAPWAP

ap1g6a-k9w8-xxx.tar

Cisco URWB

Unified Industrial Wireless image ap1g6j-k9c1-xxx.tar

WGB/uWGB

To determine the image that your IW9167EH is running, use the show version command.

  • If the show version output displays Cisco AP Software, (ap1g6a) as shown in the following example, it means that AP is running the CAPWAP image ap1g6a-k9w8-xxx.tar, which supports the CAPWAP mode.

Configuring AP to Boot up with Different Image Options

To configure the access point to boot up with CAPWAP, URWB, or WGB/uWGB mode, follow these steps:


Note


Switching between different modes performs full factory reset. Any configuration and data will be removed completely.


Procedure


Step 1

enable

Enables privileged EXEC mode. Enter your password if prompted.

Step 2

configure boot mode {capwap | urwb | wgb }

Configures AP to CAPWAP, URWB, or WGB/uWGB mode. AP will reboot with specified mode.


Upgrade IW9167EH with 17.9.x to Support WGB/uWGB

If your IW9167EH is shipped with Cisco IOS XE Cupertino 17.9.3 software and operating as CAPWAP mode, and you want to upgrade your AP to Cisco IOS XE Dublin 17.11.1 to support WGB/uWGB mode, you need to switch your AP to Cisco URWB mode first, and then you can upgrade to 17.11.1.

To determine whether your IW9167EH is running CAPWAP mode or Cisco URWB mode, use the show version command.

  • If the show version output displays Cisco AP Software (ap1g6a), your AP is running as CAPWAP mode.

  • If the show version output displays Cisco AP Software (ap1g6j), your AP is running as Cisco URWB mode.

Cisco WGB/uWGB mode shares the same image with Cisco URWB. You cannot upgrade the ap1g6j image to 17.11.1 in CAPWAP mode (ap1g6a). Because the archive download command checks image type, upgrade gets aborted if image types mismatch.

Procedure


Step 1

Convert CAPWAP mode to Cisco URWB mode.

Example:

#configure boot mode urwb
       Before image swapping device need factory reset. Are you sure to proceed? (Y/N):y
       Converting to Cisco URWB Mode...
       <rebooting…>

Step 2

Log in with default credential (Cisco/Cisco/Cisco).

Step 3

Configure Cisco URWB, to make it work in Offline mode.

Example:

#configure iotod-iw offline
       Switching to IOTOD IW Offline mode...
       Will switch from Provisioning Mode to IOTOD IW offline Mode, device need to reboot: Y/N?  Y
       <rebooting…>

Step 4

Configure networking in Cisco URWB (IP/netmask/gateway, passphrase)

Example:

Cisco-23.174.76#configure wireless passphrase unit1
Cisco-23.174.76#configure ap address ipv4 static 192.168.1.200 255.255.255.0 192.168.1.1
Cisco-23.174.76#write
Cisco-23.174.76#reload
     <rebooting…>

Note

 

Passphrase is optional, but it is recommended to assign different passphrases if you are upgrading multiple units at the same time and they are connected to the same Layer 2 network. Because Cisco URWB forms MPLS network automatically if all nodes have the same passphrase, without further MPLS configuration, your IP service might not work properly.

Step 5

Upgrade to 17.11.1.

Example:

#archive download-sw /reload tftp://<TFTP_SERVER>/<ap1g6j-FILENAME>
          <rebooting…>

Step 6

Convert the AP from Cisco URWB mode to Cisco WGB/uWGB mode.

Example:

#configure boot mode wgb
           <rebooting…>
