Switch 3850 doesn't take wlan config.

DanyRuiz

Level 1

Hi,

I have a 3850 switch (running  03.03.05SE) operating as WLC but it doesn´t take any configuration related to a SSID.

After a power failure it set the SSID to default configuration and I can´t reconfigure it (web or CLI). 

I tried to create a new wlan but it didn´t work too.

Thanks.

Hey Mate,

I hit this bug 2 weeks ago on my 3850 stack running version 3.6.3.

Below you can find the answer from TAC engineer: 

This is a known issue and the following bug filed:

CSCus85866    

Invalid Wlan configuration error when trying to change AKM to PSK 

<B>Symptom:</B>

Error when attempting to change AKM to PSK, in wlan configuration.

% switch-2:wcm:Invalid WLAN configuration. Either dot1x or psk

authentication must be configured under wpa

 

<B>Workaround:</B>

Reset appliance to defaults or configure passwd key obfuscate

Seems that the bug details are not public available that's why don't have sufficient permissions.

Pls share the CLI configuration related to this WLAN configs.

I am running 3.6.3E code in my production and did not encounter this sort of issues.

Hi Rasika,

Current config:

wlan pfr-WLAN 1 WLAN
 client vlan wireless
 no security wpa akm dot1x
 session-timeout 1800
 shutdown

After applying the following commands, wlan config doesn´t change.

security wpa wpa2 ciphers aes
security wpa akm psk set-key ascii 0 test798$
no shutdown

% switch-1:wcm:Invalid WLAN configuration. Either dot1x or psk authentication must be configured under wpa.

Thanks.

Hi,

It's a known issue, bug CSCus85866.You need to configure key obfuscate or reset your switches to defaults.

conf t

passwd key obfuscate

Hi Chris,

Could you share the bug details, I cannot see it due to permission restrictions, what codes affected. I did not have this on 3.6.x codes which I deployed.

Thanks for sharing this info chris.

Hey Chris,

Thanks for this information.

The key obfuscate configuration didn't work for me.

Regards.

Hello Christos,

"passwd key obfuscate" on code 03.06.04.E worked for me.

Thank You very much.

Hi

What code version you running ?

3850-1(config-wlan)#security wpa                           
3850-1(config-wlan)#security wpa wpa2 ciphers aes 
3850-1(config-wlan)#no security wpa akm dot1x 
3850-1(config-wlan)#security wpa akm psk set-key ascii 0 Cisco123

Did you try above ? Note that additional "security wpa" line that was not there in your config. Here is my reference
