UC560 Can't change Data VLAN IP

chris parkinson

I'm having a hard time changing the UC560 Data VLAN IP from192.168.1.60 to

In CCA, when I change the IP and submit, CCA gives me a "Java Null Pointer Exception" and freezes at "Configuring DCHP Pools and Exclusions".

Has anyone seen this before?

The UC560 is not the DHCP server on the Data VLAN, but I did configure a DHCP pool just for the sake of trying, but the IP change still failed at the same point.

OK, so I used the F2 to enable the debug screen, and this really helped.

First the debug complained about the firewall, so I deleted and reconfigured the Firewall settings.

Second the Debug complained about DHCP Exclusions.  Interestingly, the only DHCP config and Exclusion where on the Voice VLAN, but I deleted them anyway.

After that the Data VLAN IP changed succeeded, but the US500 had one more surprise in store.

I could ping the new IP, but couldn't access the UC500 with CCA.

I had to get into CCA using the Voice LAN, then delete and reconfigure the firewall settings once more.

The everything worked as it should.
