If I have 2 devices with LLDP enabled is it posible to poll data from only 1 device and create the DCF table for both devices?
You will need to have LLDP information from both devices.
On a given element A, LLDP (like any layer 2 discovery protocol such as CDP) will give you the remote information (remote chassis id, remote port id...) . For a DCF connection to be provisioned, the element and DCF interface ID of both ends need to be identified.
If you run the discovery on element A, IDP identifies the element and DCF interface ID of element A. However, the element ID and DCF Interface ID of the remote element are only known when you run the discovery on the remote element too. That's why you also need to have LLDP information on the remote element. A more elaborate explanation is available here : Implementing the Connectivity Discovery script | DataMiner Docs
Jesus,
A DCF connection is just a link between two known interfaces, in your case between devices. Therefore, having both devices confirming the relations is always the preferred approach.
Having said this, when polling LLDP you get the name of the remote device as well as the remote interface, so maybe you could transfer the data between elements for the purpose of creating the DCF links.
I hope it helps.
Thanks,
What we have seen is that polling one device will show the interface of the remote device. So, in theory you should be able to establish the relations by co-relating the interfaces in the remote device element. Given that you are polling the interfaces table of the remote device via DataMiner as well.
Thank you Rene.
So with that in mind, can I get the same information from both devices when I ask one of them as if I asked both devices individually or is there any limitation? This is because I may not be able to poll information from one device that is connected to another device that I do can poll information.
