Device discovery failed in ANM

aniortegr — Thu, 17 Dec 2009 17:19:09 GMT

Hi,

I've got the following error message when I want to import a 6506 in 12.2(33)SXI2 with an ACE module.

I've tried in ANM 2.2 and 3.0 = same problem.

Can someone help me ?

Hi Greg,

The error message you are seeing is likely triggered by some un-expected configuration on the cat6k.

It is likely your cat6k configuration has an interface defined as a switchport which has a subinterface defined on it.

This is usually not allowed on most sup versions that we have seen and hence is not modeled/ cannot be discovered in ANM.

We have bug id CSCtd94658 opened for this issue.

You could try to have your customer remove the subinterface indicated above and then try the import into ANM.

Also, they could maybe add back that interface if really required after the initial import.

Since Cat6k configs are not auto-sync'ed in ANM, they will be okay until they do a manual sync.

This workaround in also documented in the release notes of CSCtd94658.

Thanks

Sujatha

Hi,

Thanks for the answer.

I found it with the help of the TAC.

Now it is corrected but I've got another issue.

Device discovery failed: Exception occured for model:VlanModel

Exception occured for model:InterfaceModel

java.lang.NullPointerException

java.lang.NullPointerException.

do you have any idea ?

Thanks.

The other error is the following defect
