Question
: Can I connect the teamed adapters to ports in a router?
Answer
: No. All ports in a team must be on the same network; in a router,
however, each port is a separate network by definition. All teaming modes require
that the link partner be a Layer 2 switch.
Question
: Can I use teaming with Microsoft Cluster Services?
Answer
: Yes. Teaming is supported on the public network only, not on the private
network used for the heartbeat link.
Question
: Can PXE work over a virtual adapter (team)?
Answer
: A PXE client operates in an environment before the operating system is
loaded; as a result, virtual adapters have not been enabled yet. If the physical
adapter supports PXE, then it can be used as a PXE client, whether or not it is
part of a virtual adapter when the operating system loads. PXE servers may
operate over a virtual adapter.
Question
: What is the maximum number of ports that can be teamed together?
Answer
: Up to 16 ports can be assigned to a team, of which one port can be a
standby team member.
Question
: What is the maximum number of teams that can be configured on the
same server?
Answer
: Up to 16 teams can be configured on the same server.
Question
: Why does my team loose connectivity for the first 30 to 50 seconds
after the Primary adapter is restored (fallback)?
Answer
: Because Spanning Tree Protocol is bringing the port from blocking to
forwarding. You must enable Port Fast or Edge Port on the switch ports connected
to the team or use LiveLink to account for the STP delay.
Question
: Can I connect a team across multiple switches?
Answer
: Smart Load Balancing can be used with multiple switches because each
physical adapter in the system uses a unique Ethernet MAC address. Link
Aggregation and Generic Trunking cannot operate across switches because they
require all physical adapters to share the same Ethernet MAC address.
Question
: How do I upgrade the intermediate driver (ASP)?
Answer
: The intermediate driver cannot be upgraded through the Local Area
Connection Properties. It must be upgraded using the Setup installer.
Question
: How can I determine the performance statistics on a virtual adapter
(team)?
Answer
: In QLogic Control Suite, click the Statistics tab for the virtual adapter.
Question
: Can I configure NLB and teaming concurrently?
Answer
: Yes, but only when running NLB in a multicast mode (NLB is not
supported with MS Cluster Services).
