AIR-AP1562E WGB Mode

[carstenp]

Hello,

my question is, why there are only outdated or wrong documentations existing regarding APs in WGB mode.

Having a WGB, AIR-AP1562, which shows following log entrys at every roam event:

Jul 27 12:24:05 kernel: [*07/27/2023 12:24:05.8517] DOT11_UPLINK_EV: RSSI Low(-71)! Parent lost. Roaming triggered.

The first, fourth and the last line are clear to me. But the other lines?

How to disable IPv6 at the WBG?

You wont believe how disappointed I am, seeing what Cisco sells, builds and charges for licenses - leaving their partners completely alone.

Has anyone a clue, what the logging means and what is the reason for the uptime and real time difference?

Best regards

The message "Best AP not available in 3rd radio scan table" on a Cisco wireless WGB access point means that the access point is unable to find the best available access point to associate with in the third radio scan table. This usually means that the access point is out of range for other access points

  To disable IPv6 at the Cisco WBG wireless access point, you can follow these steps:

          Log in to the WBG AP using the web management interface.
         Click on the Configuration tab.
         Click on the IPv6 tab.
         Uncheck the Enable IPv6 checkbox.
         Click on the Save button.

 - The uptime and real time are not related ; uptime only counts the time interval since last boot ,

Hello M.,

thank You for the Answer.

Unfortunately the AP as a WGB has no GUI - and a very limited set of commands.

- The uptime and real time are not related ; uptime only counts the time interval since last boot-> exatly, why shows it as last boot time:

AP_Kran2_WGB uptime is 31 days, 23 hours, 35 minutes
Last reload time : Wed Oct 6 14:28:15 UTC 2021

?

Best Regards Carsten

        >...why shows it as last boot time:
 - That's a default ; for checking the time use show clock

Hello M.,

thank You for the hint - but a show clock is already shown in my first post.

Hi @carstenp 

 WGB is supported in newer APs also.

In order to disable the IPv6, use the command "ipv6 disable" on the interface.

But, this AP is Mobility express so you should be able to access the web interface which is more intuitive.

[carstenp]

Hello Flavio,

thank you for the suggestion. But there is no web interface...

All I can find is:

AP_Kran2_WGB#configure ap ?
address IPv4/6 address config
hostname Configure AP hostname
management Configure mgmt user credentials
Regards

Carsten

@carstenp  When running in Mobility express, the AP should provide you an SSID called CiscoAirProvision  and you should be able to use this SSID to run the AP setup.  The password is password

From there, you should be able to fire up a web browser and use the url mobilityexpress.cisco or http://192.168.1.1

I woud recommend to you to try even though you may have to start over on the configuration. The web interface is better for this kind of devices.

Hello Flavio,

this is the last time I repeat this: There is no GUI! The AP is running in WGB mode - it is not possible to bring the AP from ME GUI into WGB-Mode.

By the way, the command configure ap address ipv6 disable had no impact:

Got it, then you are not running mobiity express probably.

Can you share the "show running-config" here?

[carstenp]

Hello Flavio,

please excuse the delay.

To be honest, Iam not sure anymore if it was a ME-Image, but the show version command shows:

AP Running Image : 8.10.151.0
Primary Boot Image : 8.10.151.0
Backup Boot Image : 8.5.140.0

so it seems to be a ME-Image, because a lightweight-Image would be something like 15.3.3.

Hello Flavio, that was the Point:

configure ap address ipv6 disable

Thank You!
