Troubleshooting Teaming Problems
• Teaming Configuration Tips
• Troubleshooting Guidelines
When running a protocol analyzer over a virtual adapter teamed interface, the MAC address shown in the
transmitted frames may not be correct. The analyzer does not show the frames as constructed by BASP and
shows the MAC address of the team and not the MAC address of the interface transmitting the frame. It is
suggested to use the following process to monitor a team:
1. Mirror all uplink ports from the team at the switch.
2. If the team spans two switches, mirror the interlink trunk as well.
3. Sample all mirror ports independently.
4. On the analyzer, use an adapter and driver that does not filter QoS and VLAN information.
Teaming Configuration Tips
When troubleshooting network connectivity or teaming functionality issues, ensure that the following information
is true for your configuration.
1. It is recommended that, for an SLB team, all adapters be the same link speed.
2. If LiveLink is not enabled, disable Spanning Tree Protocol or enable an STP mode that bypasses the initial
phases (for example, Port Fast, Edge Port) for the switch ports connected to a team.
3. All switches that the team is directly connected to must have the same hardware revision, firmware revision,
and software revision to be supported.
4. To be teamed, adapters should be members of the same VLAN. In the event that multiple teams are
configured, each team should be on a separate network.
5. Do not enter a multicast or broadcast address in the Locally Administered Address field.
6. Do not assign a Locally Administered Address on any physical adapter that is a member of a team.
7. Verify that power management is disabled on all physical members of any team (the Allow the computer
to turn off this device to save power box on the Power Management tab in adapter Properties should
be cleared—see Setting Power Management Options in “Windows Driver and Application Installation”).
8. Remove any static IP address from the individual physical team members before the team is built.
9. 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.
10. 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.
