Cisco Cisco 2106 Wireless LAN Controller

Release Notes for Cisco Wireless LAN Controllers and Mesh Access Points for Release 4.1.191.24M-Mesh

OL-31336-01

System Requirements

Mandatory Boot Variable Update for Networks with 1520s

If your network is operating with 1520s or you plan to install 1520s in your network, you must set the
boot variable on the 1520 BEFORE upgrading from release 4.1.190.5 to 4.1.191.24M or installing a
1520 in a 4.1.191.24M network. Updating the boot variable ensures the 1520 joins correctly.

Note

You should check the boot variable setting before updating the boot.

•

If the boot system image is visible, then no boot variable update is required.

–

If upgrading from release 4.1.190.5, the system image should read:
flash:/c1520-k9w9-mx.124-3g.JMA1/c1520-k9w9-mx.124-3g.JMA1

•

If the boot system image is missing, then you must update the boot variable.

Checking the Boot Variable Setting

To check the setting of the boot variable, do the following:

Step 1

On the controller, enter the following commands for each mesh access point (MAP):

debug ap enable AP_Name

debug ap command "more flash:/env_vars" Cisco_AP
