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. Although Dell supports mixed speed SLB teaming, it is recommended that all adapters in a team be the same speed
(either all Gigabit Ethernet or all Fast Ethernet).
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.
