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.

•Make sure the link light is ON for every adapter and all the cables are attached.

•Check that the matching base and intermediate drivers belong to the same release and are loaded correctly.

•Check for a valid IP Address using the Windows ipconfig command.

•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.

•Check that the adapters and the switch are configured identically for link speed and duplex.

•If possible, break the team and check for connectivity to each adapter independently to confirm that the problem is directly associated with teaming.

•Check that all switch ports connected to the team are on the same VLAN.

•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 config- ured 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.

Under what circumstances is traffic not load	The bulk of traffic does not use IP/TCP/UDP or

evenly across the team members?	The receive load balancing is not a function of
	traffic load, but a function of the number of
	clients that are connected to the server.
What network protocols are load balanced when	Broadcom's teaming software only supports IP/
in a team?	TCP/UDP traffic. All other traffic is forwarded
	to the primary adapter.
Which protocols are load balanced with SLB	Only IP/TCP/UDP protocols are load balanced
and which ones are not?	in both directions: send and receive. IPX is load
	balanced on the transmit traffic only.
