Hello, I want to migrate WLC to Mobility Express. My WLC is in version 8.3.150.0 and the same the CAPWAP AP's I have one AP 3800 with Mobility Express 8.5.140, it's configured as the Mobility Express Primary controller I disconnect the CAPWAP AP's from WLC and connect to the ME Controller, but they don't join. Maybe because they are not the same version? How do I have to proceed? Do I have to upgrade the CAPWAP AP's to 8.5.140? how can I do that without connecting them to a controller? Or maybe is better to downgrade the ME controller to 8.3.150? How can I downgrade ME? Thanks

Thanks for your answer. So maybe now, with the rising speed of wifi it has no sense anymore to use a centralized deployment with CAPWAP tunnels to the controller and it's better to choose switch data locally? Taken into account the speed that a 802.11ac AP can reach, a 1.5 Gbps limit in a new product looks like a very low limit. So now I think I have 3 options: - Mobility Express - 9800-CL with data locally switched - or Switch Catalyst 9800 Embedded WLC Opinions?

Hello, WLC 5508 is almost EOL so we need to think in how to migrate. We have a WLC 5508 with 30 AP's and Cisco Prime for guest access. With this number of AP's I think is not necessary to buy a new pair of hardware WLC's. I'm thinking in migrate to Mobility Express or in a virtual WLC like Catalyst 9800-CL Cloud. But this virtual WLC is limited to a throughput of 1.5 Gbps, so it seems a best option choosing Mobility Express. What do you think?

"Enhanced Open" sounds great.
But meanwhile we have to offer solutions. Maybe PEAP could be a solution. It is the same for a guest user introduce his credentials in a captive portal or in the wifi configuration, so I don't understand why Cisco doesn't support that for Guest Users, or it does?
Thanks

Thanks, but I'm talking about securing the guest access. This document talks about using no-layer 2 security and web portal authentitcation.
Open wifi is never recommended:
https://www.csoonline.com/article/3246984/wi-fi/why-you-should-never-ever-connect-to-public-wifi.html
https://www.europol.europa.eu/activities-services/public-awareness-and-prevention-guides/risks-of-using-public-wi-fi
It's very easy to create MiTM attacks, packet sniffers or fake-rogue AP. After you connect to an open network, your client is going to connect always to that SSID, inside and outside your organization, without authentication, making very easy the work for attackers.
Is it possible Cisco has not another recommendation for guest access?
Thanks

Thanks, but I'm talking to use the local guest users in the controller, not in a remote LDAP server
Can we use those local guest users in a secure way different from open authentitication with a captive portal?
Thanks

I would like to secure the wireless guest access. Those guests users are local in the controller.
At the moment, they connect through captive portal without L2 security.
I don't like to use a PSK, because at the end, the PSK is going to be known for the guests.
Can we use local guest users with PEAP or LEAP? Or are they only for web authentication?
Any recommendation to secure wireless guest access?
Thanks

Hi, we have some overlapping networks in our WAN.
I need to route the traffic from 192.168.128.0 to one IP (10.3.4.7/32) through a VPN .
The problem is the router has got an interface with this network 10.3.0.0/16 and the administrative distance of directly connected networks is 0, which preveil over static route. How can I use the static route over the directly connected network?
Thanks

Hi, I have problems with the network devices every time there is a thunderstorm . Always suffer the PoE module of some switches, also some indoor access points and some network cards from PC's or printers.
It seems closed to the circuit Switch PoE - Indoor Access Point or Network devices What is the explanation? What can I do to avoid it?
Can the lightning enter through the indoor network cabling?
Or maybe through some network device not connected to UPS?
Thanks

thanks. I know but about those Cisco 1850 AP:
" For optimal traffic load balancing on the LAG ports to the AP and the controller, it is important that the switch support balancing is based purely on the L4 source and destination ports."

OK, but all the vendors have different names for 40G up to 400m over OM4, it seems ther is not an standard:
- Cisco 40G-CSR4
- Dell 40G-eSR4
- Arista 40G-XSR4
So, can I connect a Cisco 40G-CSR4 on one side and a Dell 40G-eSR4 on the other side for a 40G connection over OM4 and about 400m?

It seems 40G can reach 400m over OM4, but is it standard?
I read in the Cisco 40GBASE QSFP Modules Data Sheet:
"Cisco 40GBASE-CSR4 QSFP Modules extend the reach of the IEEE 40GBASE-SR4 interface to 300 and 400 meters on laser-optimized OM3 and OM4 multimode parallel fiber"
Is Cisco 40G CSR4 standard (I see other manufacturers like Dell have 40G-eSR4)?
Can mixed solutions of 40G over 400m inter operate?
Or is a better solution go to single moder fiber for 40g for distances longer than 150m?
thanks
