Cannot add WLC 5508 v7.6.120.0 into Prime Infrastructure 2.1

[Alvaro Rugama]

Hi everyone

Hope you can help us with this issue.

We already configure the WLC using this guide: http://mrncciew.com/2013/02/14/configuring-snmp-on-wlc/

snmp v2: enable

snmp v1: enable

default port values

community: incaenic with ip and mask 0.0.0.0 to allow access from any network or ip

traps receiver:                   community: incaenic                 ip: 10.100.100.15

when we try to discover the WLC with the PI it gave the error "SNMP Connectivity Fail"

WLC is on subnet 10.100.102.0/24 and PI in 10.100.100.0/24; there is a Catalyst 3850 between then with no access list on then.

Did someone can guide us with this?

Best Regards.

Hi,

Which SNMP credentials are you using on PI?

Have you followed the PI configuration as per below guide?

Hi Najaf

thanks for your reply

I'm using the local database credentials to reach the SNMP on the WLC, However, the only way to reach it by SNMP is enabling the Service Port on the WLC.

Don't know if there is a way to reach it from the other ports.

Hi,

Which version of SNMP are you using?

If you are using v1/v2 you should be using community string rather than local database credentials?

Regarding the service port what is the ip address assigned on the service port. From the configuration guide "Prime Infrastructure uses the preferred management IP address from the loop back interface. If the device does not have a loopback interface, Prime Infrastructure uses similar logic to the OSPF algorithm to select the router’s preferred management IP address."

Hope that helps.

Hi Alvaro,

I have the same problem with a WLC 5508. Do you already know if this is the only way to add the WLC to PI 2.1?

Hi adrianv3r

I manage to register the WLC on the PI using its physical management interface.

I connected a patch cord from the management interface to my switch core, then tried to registered it into the PI with my SNMP community and credentials; all when well, it registered without a problem.

Hope this help you

Hi vattaullu

Thanks for your reply.

I did all of that, the only way that PI can reach the WLC is through the Service Port on the WLC, have to add an internal IP addresses to the Service Port and all is working ok right now.

Don't know if there is a way to reach the WLC through the other ports.

I had the same issue.

Even though my Service port was disabled, it had previously been setup with an IP on the same subnet as Managment (not service port) interface. I changed the IP on the disabled service port to something arbitrary and unused in our network and SNMP polling started working.

It was the posts in this forum that got me on the right track.
