| Description | NLB Cluster %2 %1: Invalid bi-directional affinity (BDA) teaming port rules detected. Each member of a BDA team may have no more than one port rule whose affinity must be single or class C if multiple host filtering is specified. To add this cluster to a team, correct the port rules and run wlbs reload followed by wlbs start. %3 %4 |
| Event Information | According to Microsoft: Cause: A bidirectional affinity (BDA) team is a set of adapters on a single host that act in concert. This event is logged when this adapter has been configured as a member of a BDA team, but the configured port rules do not comply with the requirements for using BDA. The use of BDA requires a single port rule that covers all ports (0-65535), configured as either Single or Class C affinity. User Action : Correct the BDA teaming port rules, and then run ‘nlb reload’ followed by ‘nlb start’. BDA configuration is specified by the Microsoft Internet Security and Acceleration Server (ISA Server) configuration. |
