1. There are several circumstances in which your system may operate in an unexpected manner The Troubleshooting section provides information regarding unusual situations NDIS DESCRIPTION The team members are incompatible The Virtual Team driver is NDIS 6 0 and team member underlying miniport driver is NDIS 5 0 NDIS 5 1 SEVERITY Information ACTION None NDIS takes care of compatibility issues Header Data Split DESCRIPTION Incompatible adapters The team member underlying miniport driver supports the Header Data split feature SEVERITY Information ACTION None NDIS 6 1 onwards supports Header Data Split Windows 2008 drivers can handle Header Data Split If there are any old NDIS drivers in the network stack not supporting Header Data Split then NDIS dynamically turns it OFF RSS DESCRIPTION RSS Receive Side Scaling adversely affects the Virtual Team Miniport Driver IM driver SEVERITY Information ACTION None In Non 802 3ad mode or 802 3ad static mode the driver is working as a pass through driver So RSS does not affect it It creates ARP requests and receives ARP replies but if the OOB fields in the packet are set to 0 for RSS hash there is no problem In 802 3ad LACP mode creates LACP packets driver can use the information from OIDs to assign connection on the same CPU that miniport and protocol driver are using The driver disables RSS by intercepting the OIDS and reports RSS not supported Fai2. SEVERITY Information ACTION None The teaming VLAN GUI tries to set the current MAC address for the team member The driver reads the current MAC address of the adapter If team MAC address is different from the current MAC address of the adapter it sets filter type to be Promiscuous mode IPv6 DESCRIPTION Network uses IPv6 driver incompatible SEVERITY Information ACTION None Windows operating systems rom VISTA onwards use only one network stack so when the driver is bound to the TCP IP stack it can receive IPV4 IPV6 packets and it can handle both the packets The driver supports IPV6 OneCommand NIC Teaming and VLAN Manager User Manual Page 17

Cs are combined this way the group is called a team Why Teaming NIC teaming has several advantages e Increased bandwidth Two or more Ethernet connections are combined to share the load thus increasing bandwidth e Load balancing Link aggregation enables distribution of processing and communication across multiple links e Higher link availability Prevents a single link failure from disturbing traffic flow Teaming Types There are different types of teaming e Switch independent e Failover If configured for fault tolerance the system provides only failover e Smart load balancing If configured for load balancing failover is included e Switch dependent e Generic trunking Link aggregation static mode e Link Aggregation Control Protocol LACP Failover FO Failover is a basic feature of teaming Though a team may have multiple members only one member is active at a time When the active team member disconnects due to link down disabled or any other reason the failover mechanism selects another team member which is in linkup state and traffic continues All the team members use the same MAC address the MAC address of the primary team member When the primary team member reports linkup state traffic fails over to the primary adapter if the team is configured for auto failback Smart Load Balancing SLB Load balancing works with any Ethernet switch It requires no trunking configuration of the switch itself The
