Upgrades the IW9167EH from Cisco IOS XE Cupertino 17.9.x to Dublin 17.11.1 to enable WGB/uWGB mode support.

This procedure describes how to upgrade the IW9167EH from Cisco IOS XE Cupertino 17.9.x to Cisco IOS XE Dublin 17.11.1 to enable WGB/uWGB mode support.

The IW9167EH is shipped with Cisco IOS XE Cupertino 17.9.3 software and operates in CAPWAP mode. To support WGB/uWGB mode, you must upgrade your AP to Cisco IOS XE Dublin 17.11.1. First, switch your AP to Cisco URWB mode. 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 ). If the archive download command detects a mismatch between image types, the upgrade is aborted.

Procedure

1.

Use the configure boot mode urwb command to convert CAPWAP mode to Cisco URWB mode.

Example:

Device# 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…>
2.

Log in with default credentials (Cisco/Cisco).
3.

Use the configure iotod-iw offline command to configure Cisco URWB, to make it work in Offline mode.

Example:

Device# 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…>
4.

Configure networking in Cisco URWB by setting the IP address, netmask, gateway, and passphrase.

Example:

Device# configure wireless passphrase unit1
Device# configure ap address ipv4 static 192.168.1.200 255.255.255.0 192.168.1.1
Device# write
Device# reload
<rebooting…>
Note

The passphrase is optional. However, it is recommended to assign different passphrases when upgrading multiple units simultaneously on the same Layer 2 network.

If all nodes share the same passphrase, Cisco URWB automatically forms an MPLS network without additional MPLS configuration. As a result, your IP service might not function as expected.
5.

Use the archive download-sw /reload tftp://tftp-server/ image-name command to upgrade to 17.11.1.

Example:

Device# archive download-sw /reload tftp://10.10.10.5/ap1g6a-k9w8-tar.17_11_1_160.tar
 <rebooting…>
6.

Use the configure boot mode wgb command to convert the AP from Cisco URWB mode to Cisco WGB/uWGB mode.

Example:

Device# configure boot mode wgb
 <rebooting…>
