Wireless Access

hi gents,
I am running a two node cluster of 7210 on 8.6.0.17 with 250 access points.
Each controllers is connected with one interface to a data center switch.
But one controllers is on poor health saying: "Controller has at least one uplink with poor health".
Looking on the switch interface everything is looking fine at my pov.

How is poor health for one uplink defined? What needs to happen on an interface to get rated as poor?

I just updated from 8.6.0.9 to 8.6.0.17 but nothing changed.
Looking at the mobility conductor dashboard, it says no client is connected to the controller with poor health but 177 are connected to the one with good health. Is that normal or are the clients getting connected to the good controller because the other one is on poor health?

Go on the commandline of one controller and type "show lc-cluster group-membership" and see if it sees the other controller.

This is your problem: peer 192.168.96.53 128 L3-Connected CONNECTED  

There is probably a client VLAN that is not connected between the clusters in your controller and you need to either (1) exclude the VLAN from the cluster profile or (2) make sure the controllers can see each other on that VLAN.

Use the command " show lc-cluster vlan-probe status" to find out which VLAN that is.  L3-Connected means that your cluster doesn't have a proper failover functionality.

Problem solved.
There was a WAN Uplink configured with no connection. Who ever did that in the past..
After deleting health is good now.

Hi, have you defined a lacp port-channel and ended up using just 1 cable (like you metion)? 

If you have a 2-port lacp defined and only 1 cable connected, the controller may tell you poor healt.


I hope this helps
