Can't associate R750 to SZ5.2 when R750 has static IP address.

HI.

I recently heard that from partner we can't joining R750 with SZ5.2 when R750 has static IP address.

Thus I tested that, and I got same result.


Below is syslog on R750.

When  R750 is configured static ip address, he don't update ssh public key by any reason.

Mar 12 01:47:16 RuckusAP daemon.err cubic[770]: apcfg_general_get_wan_ipv6:1119 Get IP error. stop rsm config get/set, please check the config key and value

But When  R750 is configured dynamic ip address, he did update ssh public key well.

Is there a bug report about this symptom?

Hi Tim,

There is no issue reported in past for R750 with DHCP address facing same issue as discussed in this thread.

I request you to log a case with support.

In the meantime, please check below:

1- To avoid hitting static IP issue mentioned in this thread, please upload AP patch 5.2.0.0.5030 and update AP zones to it (If controller is running on 5.2.0 version).
2- Is the AP discovered on the controller? If yes, what events you see for this AP in the controller's event and alarm section?
3- Make sure port 22 and 443 are open in any firewall between AP to controller.
4- SSH into the AP and check AP syslog for any major error which may be preventing AP to get upgrade/configuration_update/SSH session. Command to see syslog is "get syslog log". You can also provide this information when opening the case with support.

We have vSZ and have the exact same issue trying to get one R510 AP to connect... We have plenty of APs on several different zones under the same vSZ controllers and all connect seamlessly... not this single one.

Patch has been applied last year.

Latency to the smartzone controller, from said location is high (>600ms). Would that be a problem?

Hi Cristiano,

600ms is very high and could be cause of this issue.
