Device name is not updating in NFA

Issue/Introduction

Recently we have changed name of 2 routers, but those names are not automatically updated in NFA. We are able to poll the device from Enable Interfaces.

Environment

Component: Network Flow Analysis

Cause

The Service "CA NFA DNS/SNMP Proxies" on the Harvester may be caching the old hostname. 

Resolution

Try recycling all services on the Harvester machine, then run an SNMP Refresh of the devices in Netops Portal. 

 

Additional Information

In older versions of NFA (10.x and earlier) that used the old (obsolete) Flash Admin GUI, there was another potential cause of these symptoms:

This would happen if the device name was previously set under "Physical & Virtual" in the old Flash NFA Administration GUI.

Once you made a change to a device name in Physical & Virtual, that would override whatever name information we got back via SNMP.

 

To check whether this is happening in your environment, get the output of the following Mysql command on the NFA Console machine:

 

mysql -unetqos -pnetqos reporter

select devicename,routername from routers where routername is not null;

 

*****

The output of that will list out any routers that were set to overrride the Router name.

If this output shows your device with the old name, we can use MySQL commands to set it back to NULL.  You can contact Support for assistance with these commands.
