Abstract
The present invention provides methods of checking for duplicate port globally unique identifiers during a discovery of a subnet of a system using a channel adapter. These methods allow a Subnet Manager, an Infiniband entity for managing the Infiniband topology, to detect invalid ports that have matching GUIDs. An additional feature is that a recently added port with a duplicate GUID will not replace an original port with the same GUID, but instead will be left out of the network.
