8.
A team that requires maximum throughput should use LACP or GEC\FEC.
In these cases, the intermediate driver is only responsible for the outbound
load balancing while the switch performs the inbound load balancing.
9.
Aggregated teams (802.3ad \ LACP and GEC\FEC) must be connected to
only a single switch that supports IEEE 802.3a, LACP, or GEC/FEC.
10. You should not connect any team to a hub, because hubs only support half
duplex. Hubs should be connected to a team for troubleshooting purposes
only. Disabling the device driver of a network adapter participating in an
LACP or GEC/FEC team may have adverse affects with network
connectivity. You should physically disconnect the adapter from the switch
before disabling the device driver to avoid a network connection loss.
11.
Verify the base (Miniport) and team (intermediate) drivers are from the same
release package.
12. Test the connectivity to each physical adapter prior to teaming.
13. Test the failover and fallback behavior of the team before placing into a
production environment.
14. When moving from a nonproduction network to a production network, it is
strongly recommended to test again for failover and fallback.
15. Test the performance behavior of the team before placing into a production
environment.
16. Network teaming is not supported when running iSCSI traffic through
Microsoft iSCSI initiator or iSCSI offload. MPIO should be used instead of
Cavium network teaming for these ports.
17. For information on iSCSI boot and iSCSI offload restrictions, see
Troubleshooting Guidelines
Before you call support, make sure you have completed the following steps for
troubleshooting network connectivity problems when the server is using adapter
teaming.
1.
Make sure the link light is ON for every adapter and all the cables are
attached.
2.
Check that the matching base and intermediate drivers belong to the same
release and are loaded correctly.
3.
Check for a valid IP address using the Windows
ipconfig
command.
4.
Check that STP is disabled or Edge Port/Port Fast is enabled on the switch
ports connected to the team or that LiveLink is being used.
