Re: Ask the Expert: Understanding, Configuring, and Troubleshoot

No Problem,

As of release 3.3, we now support nine switches in a stack.  Previous to the 3.3 release, we only support a stack of four at a time.

reference: 3850 Stacking

This is one of my previous posts that expanded on the 3.3 release features

Luke, Colby, Nick -

I have an SSID configured for Web Authentication however, my clients are unable to receive the splash page. How do I resolve this issue? 

Thanks for the help.

Hello Evan,

This is a good question.  Web authentication rediect failures can fail for a number of reasons.  These are the common issues seen here:

Client missing an IP or unable to ARP for it'd default gateway.

DNS resolution is failing

Mis-config on the web authentication

Captive portal disabled (relevant only for Apple devices)

I would first suggest disabling web authentication and ensure your client can reach the internet and resolve DNS as this will confirm the first 2 items.  Next, take a look at the config and compare it to this section of the deployment guide.  Depending on your config you will need an AAA list, a global and seperte web auth paramater map configured, and your WLAN configure for web auth referencing these 2 things.  Lastly, enable captive portale if you are using Apple devices.  You may also want to consider being on 3.2.3 or 3.3 code for complete captive portal support.

If the above do not work to resolve the issue feel free to open a TAC case and we'll be able to look into this one further.

Re: Ask the Expert: Understanding, Configuring, and Troubleshoot

Hi Guys,

When we managing 3850 (configured as MC) via Prime, should we add it as a switch or as a WLC ? Once it adds as a switch, does Prime represent it correctly as a WLC if we have that configuration ?

In my case I have switch management & WLC management on the same vlan & there are no two different IP address for SW & WLC itself ?

Regards

Hello,

This is fine.  There isn't a seperate switch and WLC with this as it is all intergrated.  This is a good guide on how to add your device to Prime.

Re: Ask the Expert: Understanding, Configuring, and Troubleshoot

Hi Nick,

I got a 3700 AP under EFT & was able to get it working with 7.6.x without any issue.  I got software code 03.09.06.MZP for 3850/5760 but could not get it working with 3850. AP get registered, but Radio interface get disabled once AP registered to 3850.

What are the possible cause for this ? Is there any troubleshooting commands I can use to find the cause?

Hope you can point me to a right place. Even under EFT documentation there is nothing much to assist in this situation

Re: Ask the Expert: Understanding, Configuring, and Troubleshoot

Hi Nick,

Give to little bit more information on this, AP (AIR-CAP3702I-Z-K9) is in "Z" regulatory domain which is latest addition to AU/NZ. I suspect 3850 code given to us may not work with this based on the below error msg I am getting when try to configure the 802.11a/n/ac radio. Can you confirm this please ?

Here is the 3850 information.

3850-1#sh wireless country configured

Configured Country.............................: AU  - Australia

Configured Country Codes

        AU  - Australia : 802.11a Indoor,Outdoor/ 802.11b / 802.11g

The code you are running ins't a normal build of code.  You are correct that your country code is probably causing the issue here.  I'll need to direct you to open a TAC case for assitance with enabling support for the -Z country domain.

Re: Ask the Expert: Understanding, Configuring, and Troubleshoot

Hi Nick,

Thanks for the reply.

Since I am doing EFT would TAC support me on this ? They may say they are not aware of such code.

I already forward the request to Cisco AM to get me a CA resourece who can help me on this.. but no luck so far

Hi Nick

I was wondering what will be the best wireless router to provide wireless internet to a 10 unit 3 stories apartment building? I'm currently using a motorola SB6141 cable modem with a linksys EA6500 wireless router. Timewarner is the broadband provider. Everybody in the building gets good connection its just I have to reset the wireless router about once every two weeks. Please help. thanks.

Hello Adel,

I'm not too sure why the router is acting up.  If you want to root cause that I would suggest reaching out to Linksys support.  They will be able to provide more direction on that issue.

Could paste what configure you were attempting and what version you're running on the 3850?

Thanks!

Sure:

Cisco IOS Software, IOS-XE Software, Catalyst L3 Switch Software (CAT3K_CAA-UNIVERSALK9-M), Version 03.02.02.SE RELEASE SOFTWARE (fc2)

!

the error got rolled over from buffer....but below is what i was putting in, and right after the "Warning: The cli will be deprecated soon"  error pop up.....but it still took it however....I just thought it was strange.

tacacs-server host X.X.X.X

All this means is that we changed the syntax some. It will still work, but eventually will be removed in later versions. I just tested this in the lab and got the same thing. It will also tell you the new syntax.

Cisco IOS Software, IOS-XE Software, Catalyst L3 Switch Software (CAT3K_CAA-UNIVERSALK9-M), Version 03.03.00SE RELEASE SOFTWARE (fc1)

3850(config)#tacacs-server host 1.1.1.1

Warning: The cli will be deprecated soon

'tacacs-server host 1.1.1.1'

Please move to 'tacacs server ' CLI

Therefore in the future we will be using tacacs sever intead of of tacacs-server host. This  is usually to fall into line with other platforms to make it easier to configure when moving between platforms for platform independent features, such as tacacs.
