Re: Layer 2 Connection and Related Interfaces

Hello,

 

yes, you are right - we are trying build L2 connection also from these tables - NodeL2Connections - Interfaces. In nodeL2Connections we store bridge data (CAM table) - so if these devices have been comunicating together, we might stored MAC address on one side.

 

"Layer 2 Connection but these Nodes have many Interfaces in the dbo.Interfaces table and from this table we can not determine both Interfaces related to a Layer 2 Connection"

Please clarify. You haven't found corresponding match?

 

You can use this SQL query to find possible mathces.

 

A -> B connection

 

SELECT nodel2connections.nodeid, macaddress, interfaces.interfaceid
FROM nodel2connection left outer join on nodel2connections.macaddress = interfaces.physicaladdress

WHERE nodel2connections.nodeid  = A and interfaces.nodeid = B

 

A <-B - just replace last line - WHERE nodel2connections.nodeid  = B and interfaces.nodeid = A

 

"Does Solar Winds Orion show the Interfaces connected by a Layer 2 Connection? If so, in which table(s)?"

 

Check TopologyData (NPM 10.6) / ToplogyConnections (10.7 RC) - if connection was generated, you will find sourcenodeid - mappednodeid and also if we know about interfaces, you will also find details about sourceinterfaceid, mappedinterfaceid.

 

Hope it helps.

 

 

Best regards,
John
