Serial Interface reporting no status

Jump to solution

no status on my serial interface. NNM doesn't see this interface. Does anybody know, how to get NNMI to monitor a point-2-point link?

You're saying two distictly different things.  NNMi will either be able to identify an interface on your device or it wont, this depends on the MIB support from the vendor for that model. You are also IMHO implying that NNMi is not Managing  a serial interface when you want it to be managed.

 

For NNMi to automatically manage an interface with out of the box settings it much be connected to another device in NNMi's inventory and there must be sufficient information availble to make the association between the two devices that they are indeed connected to each other  (L2 information derrived from discovery protocols like CDP or LLDP, CAM tables, etc. or L3 information such as ARP table entries)

 

 

You can force NNMi to override this behavor using specific node or interface group  settings

 

By default, only connected Interfaces are polled. These settings extend the set of monitored interfaces. It is recommended to use them with small node or Interface Groups. See Help → Using the Monitoring Configuration form.

Sorry for the confusion. The interface went down the other day and NNMI didn't give any alerts.. Can someone help me with this issue please?

The issue is that the interface is not managed (other color than tan ball) so it wont generate an alert on state change.  So theres obviously not a sufficent information to automatically manage that interface so you will need to create a node group containing both end points and for its monitoring settings  enable the unconnected interface check box.

Have a nice day 🙂

We don't manage the other end. That belong to the ISP.

That's why you need to follow the instructions Andy provided, to explicitly tell NNMi to monitor that unconnected interface. In your case the node group would only contain your end of the link.

That worked thanks. Sorry for not following the direction.

Andy or Lindsay

Thank you for your help. I have another problem with F5 sub-interfaces (1.1 1.2 1.3 n 1.4) not being manage. Can you recommend the best solution?
