Troubleshooting Teaming Problems
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 QLASP and shows the MAC address
of the team and not the MAC address of the interface transmitting the frame.
QLogic suggests that you use the following process to monitor a team:
 Mirror all uplink ports from the team at the switch.
 If the team spans two switches, also mirror the interlink trunk.
 Sample all mirror ports independently.
 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.
 Although mixed-speed SLB teaming is supported by Dell, QLogic
recommends that all adapters in a team be the same speed (either all
gigabit Ethernet or all Fast Ethernet). For speeds of 10Gbps, QLogic highly
recommends that all adapters in a team are the same speed.
 If LiveLink is not enabled, disable spanning tree protocol (STP), or enable an
STP mode that bypasses the initial phases (for example, Port Fast, Edge
Port) for the switch ports connected to a team.
 All switches that the team is directly connected to must have the same
hardware revision, firmware revision, and software revision to be supported.
 To be teamed, adapters must be members of the same VLAN. In the event
that multiple teams are configured, each team should be on a separate
network.
 Do not assign a locally administered address on any physical adapter that is
a member of a team.
 Verify that power management is disabled on all physical members of any
team.
 Remove any static IP address from the individual physical team members
before the team is built.
