Hello,
I am trying to monitor a CISCO 3725 Layer 3 switch with NetXMS through SNMP. I configured the switch with the appropriate community string and the detection in NetXMS console was successful. But, when i try to configure a Data Collection Item, it says that it is not supported. 
Joint, is the configuration of the DCI.
What should i do to make it work please?
Thanks in advance.
			
			
			
				There will be other OIDs below the OID you showed us in the screenshot which hold the actual values.
The OID in your screenshot is just a part of the path, not the actual destination where values are held.
Go to MIB Explorer, past that oid, and walk it.
You will see actual OIDs which hold values then
			
			
			
				Hello, and thanks for your answer.
I took your answer as if the OID that i were looking for was wrong. I searched in Cisco Websites and took another OID, which is :     1.3.6.1.4.1.14179.1.1.5.3     agentFreeMemory. But in the console, it gives me the same error. I don't know what i have to do with it now.
Joint, the error alarm from the Console.
Thanks in advance.
			
			
			
				Again, the same thing I mentioned in the above post.
Go to MIB Explorer, past that oid, and walk it.
You will see actual OIDs which hold values then.
Its the same issue for this OID as the previous one.
			
			
			
				thank you so much for your help. I'll search deeper to find out what's not going alright with these OIDs.
			
			
			
				Thank you so much, that works finally, i did as you said, and it works finally.
			
			
			
				You dont need to create DCIs for this.
Just go to the "Interfaces" tab, all port statuses can be seen there.
(and port's admin status too)
