We are getting repeated errors from the ipdevpoll statuscheck job concering a customer's Aruba switches:

KeyError: <NetboxEntity: Chassis (Unnamed entity) at aruba-sw>
It seems this problem arises because the Aruba switches do not present with any chassis entities in ENTITY-MIB::entPhysicalTable, but as a stack within a stack (although the switch really isn't stacked).
This has unintended consequences for the system plugin, which, since it cannot see that any chassis devices have been found, creates a new one to store a collected software version in. The system plugin does not run during a statuscheck job, however, so the algorithm that checks for missing devices fails. |
