Monitoring, Management & Location Tracking

Sometimes, we may ran into the following error while trying to access VisualRf Floor plans in Airwave.

We need to confirm two things to isolate the issue here. They are:

1. Logged into AMP and Navigate to AMP Setup --> Roles. 

2. Check the privileges assigned to the logged-in user. In this case, we have logged with username admin, that has VRF read/write access.

3. Check the visualrf logs located at /var/log/visualrf/visualrf.log.

It would show the below messages:

By default, role_id 7 corresponds to visualrf access.  

Since, the error says missing authorization info, check users table to verify the user with role_id = 7 is enabled. In this case, the user with role_id = 7 is disabled.

If you see user role_id = 7 is disabled, enable it using the following command:

[root@localhost visualrf]# dbc update users set is_enabled = 1, login_attempts = 10 where role_id =7; 

To restart visualrf from the terminal, use the below command:

[root@localhost visualrf]# psk airwave.visualrf.jar

To restart VRF from GUI, navigate to VisualRF Setup and set Enable VisualRF Engine to No and Save. Re-enable it again and save.

VisualRF Floor plans would now load without any issues.
