Cisco Wireless LAN controller 5520

manzeel — Mon, 05 Jul 2021 13:20:09 GMT

Dear All,

Need your feedback regarding cisco wireless lan controller 5520

Do we need to upload cisco boot image for cisco wlc 5520 controller in UCS Server..I am able to login to Cisco Intergrated Management controller but after that server goes to message in console saying "Cisco Bootloader Loading Stage 2..."

Need your input in this.

Thanks In Advance

The CIMC is to access the UC

Scott Fella — Tue, 10 Jan 2017 14:31:08 GMT

The CIMC is to access the UC side, but if you console into the 5520 doe you get the startup wizard? The CIMC can be upgraded but I guess my question is, do you see anything from the console?

If nothing is showing, then opening up a TAC case is probably a good idea.

Hello Scott,

When I opened console from CIMC it says "Cisco Bootloader Loading Stage 2." i opened the server for around 45 mins but i did not see any progress besides above message. do i need to upload image or it comes pre-loaded since it is a server.

Don't use the console from

Scott Fella — Tue, 10 Jan 2017 14:42:59 GMT

Don't use the console from CIMC, but connect a console cable to the console port. Make sure you only have a connection on the console and not the CIMC at the same time. I ran into the same issue when the console port was connected to a term server.

There is no dedicated console

manzeel — Tue, 10 Jan 2017 15:23:09 GMT

There is no dedicated console port, however i used the Front panel KVM/Console connector and still got the same output.

You don't have anything

Scott Fella — Tue, 10 Jan 2017 16:00:45 GMT

You don't have anything connected to the rear console port when using the KVM?

There is a console port on the rear.

Dear Scott,

Thanks for the help.. i am able to access my device now.

Although i have another problem..

In my switch i have configured trunk port to wLC with vlan 20,30 and 1

>for service port i have 192.168.1.0\24 network :i.e 192.168.1.250 which i am able to access wLC and ping

>for management interface vlan 20: ie:10.20.20.20

>for Guest Network vlan 30:10.30.30.30

in switch i have configured ip for both vlan 20 and 30 and from switch i am able to ping AP ip address in vlan 20 as well as vlan 30.. however i am not able to ping management ip of WLC.

due to which my ap are not able to join the controller..

so please help me with it...

Your service port should not

Scott Fella — Wed, 11 Jan 2017 15:25:24 GMT

Your service port should not be on a routed network that has connectivity to the management interface. Since you have an IP address for the service port, don't connect it to the network.

Your management interface should also be tagged for vlan 20 and since you are allowing vlan 20 on the trunk you should be able to ping anything on that subnet.

Post your show interface detailed management and your switch port config.

if you configure another port on vlan 20 and connect your laptop, can you PING the gateway?

Dear Scott, Thanks for the help, i am able to access the controller by make some changes in the configuration and all aps are communicating with WLC.

Scott,Need your suggestion regarding deployment in my organization.

In my organization i have existing 192.168.1.0/20 network pools for wired clients with 10 branches all receiving ip from Central DHCP Server. now my organization wants to connectivity through wireless with having 172.16.1.0/20 for corporate wireless clients and 10.0.1.0/20 for Guest users on all branch and HO. I will have three ssid broadcast ed from wlc for above network. i will trunk port all the vlans to wlc and MAP ssid as per vlan. now my question is what should i configure in switch for ap as trunk or access since i will have probably 1 or may be 2 ap in branch for now and need to broadcast all three ssid with tagged vlan to respective networks. Does WLC will take care for the tagged ssid in branch. also as some of the traffic of the branch need to terminated in branch only for the locally available servers without bringing those traffic to wlc.will AP in Flex Mode will meet the requirement for branch and local for HO.

If you plan on putting

Scott Fella — Thu, 12 Jan 2017 16:00:06 GMT

If you plan on putting traffic local to each site, then FlexConnect is what you need. AP's will need to be on a dot1q trunk and vlans allowed. The AP management will need to be the native vlan for that trunk also. You will need to enable FlexConnect local switching on the wlan and then also create FlexConnect groups so you can map the wlan to the vlan at that site. If the vlans id is the same on all sites, it makes it easy, but not a requirement.

Do i have to enable flex mode

manzeel — Fri, 13 Jan 2017 06:37:52 GMT

Do i have to enable flex mode in ap and map wlan-vlan in HO Office too in order to broadcast all the vlan network over wireless through WLC?

If the APs are local to the

Scott Fella — Fri, 13 Jan 2017 10:40:14 GMT

If the APs are local to the controller, then no. Leave them in local mode. Only AP's that you want to not have traffic tunnel back to the controller is when your AP mode needs to be flex.

manzeel — Sat, 21 Jan 2017 15:01:29 GMT

Scott my WLC 5520 creates continuous high sound which is unbearable. initially both unit were running in single power mode but when i used dual power mode problem is still the same. As WLC 5520 is new to me and i have only previously used 2500 series controller. Is this controller creating such sounds is normal or do i need to worry about it. I am running both wlc in my lab for past 10 days and sound that both controller creates is very high.

The 5520 is a UCS server and

Scott Fella — Sat, 21 Jan 2017 15:28:14 GMT

The 5520 is a UCS server and sounds like an airplane taking off. Yes it is normal as the 2504 is very very quiet.

Dear Scot,

In my deployment Scenario,5520 Management and Ap-Manager Interface are same, when i tried to used External Authentication Server like Radius Server to map with my Management Interface, Wireless users are not authenticated and in WLC log shows that radius server did not accept any request. But when i map with Service ip than users get authenticated. Since Service is not in production i cannot use that interface for mapping with radius server. So please suggest what i am doing mistakes here and also radius server is out of reach and access for which i cannot see the logs what is logged over radius server.

Radius by default uses the

Scott Fella — Tue, 28 Feb 2017 16:18:29 GMT

Radius by default uses the management interface. The service port address should not be routable and not have connectivity to the management port. On the wlan, there is a radius override in which you can specify the interface for radius:

http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/b_cg74_CONSOLIDATED_chapter_01100101.html

You shouldn't have to change this but make sure it's not pointing to your service port.

Also note, if it's working with the service port, that means the radius server aaa client for the controller has the service port address in which it should be the management address. Have your radius support team make sure the aaa client is defined using the management ip.

Hello Scott,

Hello Scott,

Hope ur doing good.

i need your input in my following issues:

Recently i have upgraded my WLC firmware from 8.1.120 to 8.2.141. Due Existing Security Measures places in in my Premises, AP are not able to discover WLC through DHCP or through DNS for which need to point respective WLC from all AP though CLI. Before Upgrade I am able to access Cisco AP from Console but after Upgrade I am not able to access AP through CLI. I even downgraded to its original firmware, but issue remains the same.

I performed factory reset of individual AP though WLC for which AP has been successfully reset to its factory default. However, I am not able to access AP through CLI. After reboot it immediately goes to discovery mode and does not provide prompt to enter AP through CLI. I waited around 45min in which I am not able to access AP.
As per my organization policies of assigning Static IP to individual AP, I Successfully configured static IP from WLC. Through AP Console I am not able to reach its gateway and find arp as well as of WLC Management IP. However, I am able to reach from laptop from same Switch Port. More Over AP takes around 40-50 min to reach WLC and gateway through static assigned IP Address which is very lengthy than its standard time for which we may not be sure it will work or not.
For most of the AP i have statically pointed to WLC from respective AP CLI, which was working fine for some period of time. Due to some reasons i need to reboot my AP. After that my ap got disconnected from wlc and after 2-3 hrs they get connected.

Hi,
Today I had done the CIMC upgrade and have got the same message " Cisco bootloader loading stage 2". This message is actually normal and doesn't represent the firmware is loading.

After I mapped the IOS file and rebooted ,this would show the Cisco UCS Host Upgrade utility. Afterwards it was showing me the above message . Just exit and login back to CIMC GUI and goto Admin > Firmware and proceed with Update option. This should work 🙂 And I was connected through the console as well.

Thanks,,

Yeah had that to. Login to CIMC and change the FAN profile from highest to Balanced. This is hidden under Compute (click the left top icon to open the menu in CIMC) - Power Policies - Fan Policy. Afterwards the server should be considerable less noisy. Please note, I don't know if this is actually supported by Cisco. My WLCs are in cooled data centers and there it is no problem for me.
