11.
It is not recommended to connect any team to a hub, as a hub 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. Broadcom
recommends that the adapter first be physically disconnected from the switch before disabling the device
driver in order to avoid a network connection loss.
12.
Verify the base (Miniport) and team (intermediate) drivers are from the same release package.
13.
Test the connectivity to each physical adapter prior to teaming.
14.
Test the failover and fallback behavior of the team before placing into a production environment.
15.
When moving from a nonproduction network to a production network, it is strongly recommended to test
again for failover and fallback.
16.
Test the performance behavior of the team before placing it into a production environment.
Troubleshooting Guidelines
Before you call for 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 Ethernet 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 package and are loaded
correctly.
3.
Check for a valid IP address using the
ipconfig
command for Windows.
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.
5.
Check that the adapters and the switch are configured identically for link speed and duplex.
6.
If possible, break the team and check for connectivity to each adapter independently to confirm that the
problem is directly associated with teaming.
7.
Check that all switch ports connected to the team are on the same VLAN.
8.
Check that the switch ports are configured properly for Generic Trunking (FEC/GEC)/802.3ad-Draft Static
type of teaming and that it matches the adapter teaming type. If the system is configured for an SLB type of
team, make sure the corresponding switch ports
are not
configured for Generic Trunking (FEC/GEC)/
802.3ad-Draft Static types of teams.
