Q: Why use teaming?
Teaming allows for high link availability (fault tolerance). If one of the underlying physical NICs is broken or
its cable has been unplugged, the OS will detect the fault condition and automatically move traffic to
another NIC in the bond. This capability eliminates a single point of failure for any one physical NIC and
makes the overall network connection fault tolerant.
In addition, teaming helps with load balancing. Outgoing traffic is automatically load balanced based on the
destination address between the available physical NICs. Load balancing of incoming traffic can be
achieved with a suitable network switch.
Q: What advantages does teaming provide?
Teaming can improve availability and capacity.
Q: How does teaming work?
Users create, modify, and delete teams (or bonds) using tools that are available from their OSs. Creating a
team involves picking which available physical ports belong to the team, and then choosing which type of
team to create. The type of teams that are available depends on the OS that is deployed.
Q: What are its limitations?
Switch-dependent teaming is not currently supported whenever iSCSI or FCoE is enabled on the partition.
Q: Is WoL supported?
No, WoL is not supported on the 8200 and 3200 Series Adapters.
NIC TroubleShooting/Diagnostics
NIC Linux Diagnostics
This section covers the following information for user diagnostics for Linux NIC driver management
applications:
• "Running Linux User Diagnostics" on page 73
• "Linux Diagnostic Test Descriptions" on page 75
• "Linux Diagnostic Test Messages" on page 75
Running Linux User Diagnostics
Linux user diagnostics include QConvergeConsole diagnostics and ethtool diagnostics.
Note: Information on installing and starting the GUI version of QLogic's QConvergeConsole utility is
provided in the QConvergeConsole User's Guide. All procedural information for that utility is
covered in the QConvergeConsole Help System.
QConvergeConsole Diagnostics QConvergeConsole CLI-based diagnostics include the following
commands:
• To enable or disable the port beacon, issue the following command:
qaucli -pr nic -beacon [cna_port_inst] <on|off>
• To run an internal loopback test, issue the following command:
qaucli -pr nic -intloopback <cna_port_inst> <tests_num> <on_error>
where tests_num is the number of tests (1–65535) and on_error is either 0=Ignore or 1=Abort
