Issue/Introduction

Device Interface Port Gi1/0/1 is missing in Spectrum Interfaces tab and Interfaces list even though it exists on the device. Despite rediscovering/reconfiguring the device model, the port is still not listed under the device model's interface tab.

Cause

On the device in its MIB data, the IfAlias for the problem port (call it <Y>) is set as "connection to port <X>" whereby <X> is another port. So when the naming scheme for the port is uses the IfAlias, then it reads this as the other port it is connected to (i.e. port <X>) instead of <Y>.

Environment

DX NetOps Spectrum 20.2 or later

Resolution

Set the following attribute on the Device model to 'No':

Use_If_Alias       0x11f80

And then reconfigure the device model
