Default Eliminating duplicates when HostName change

Hostname changes seem to result in duplicate configs in OE. One with the old hostname and a new config with the new hostname.

Is there any way to get a list of devices (configs) where the hostname no longer matches the config?

Could you add a option to the benchmark process to rediscover the device and eliminate the old config if the hostname changes? or just rename the config in Netbrain to match the new hostname?

Default Re: Eliminating duplicates when HostName change

Along the same line I have one physical device with two different names in DNS (leftover cleanup that never occurred). In order to keep the device count under control is there a way to look for duplicated devices like that?

router-fa0/0 == 192.168.1.1, DNS == router_old
router-fa0/2 == 192.168.2.1, DNS == router

In NB as two devices: router & router_old but really only one box.

You guys showing the two cases below for device hostname changes:
1. IP same, hostname changed (recoyle's case):
- After auto discovery, netBrain will list both hostnames under the "Interfaces of duplicated IP" window in Workspace > "Topology Stitching" dropdown menu. You can manually select the right hostname. For the old hostname, you can remove it from workspace in workspace pane.
- We'll add more features to the duplicated IP table, so you can see the "last modified time", config file by right click, also easy to remove from workspace by right click, auto select the last discovered hostnames assigned to the IPs as your suggestion, etc.
2. IP also changed (Erick's case):
- netBrain will discover the new hostname with new IP, while keep the old one (hostname/IP) in workspace. But the old one will be in the "missed devices" in "Discovery Report" window under Workspace menu. To double check on the fail-to-discover devices, you can select the missed devices, right click menu > Discover selected devices. If you're sure those devices are disconnected, you can select them, right click menu > remove selected devices from workspace.

So I figured out my issue, router side, now trying to figure out the NetBrain side. When we removed the old router we put the IP on as a standby address and left it in DNS so that the general population would not realize the router was removed. In the end NB still shows the device as there so I manually deleted it.

In new release OEv4.0x, there is a new column in "Tune live access" table to list all devices with hostname changes. Please follow the instruction below to update the workspace if there are hostname changes in the network.
1. run Tune live access
2. sort by hostname column and select items with hostname changed
3. right click on selected items > export select IPs
4. right click on selected items > remove from workspace
5. run discover via ip range by import above exported IP list
6. launch duplicated IP manager from workspace menu > topology stitching, verify the devices and remove the ones not existed.
