Broadcom Gigabit Ethernet Teaming Services: Broadcom NetXtreme BCM57XX User Guide

file:///C|/Users/Nalina_N_S/Documents/NetXtreme/English/teamsvcs.htm[9/5/2014 3:32:13 PM]

Answer:

Broadcom's teaming software only supports IP/TCP/UDP traffic. All other traffic is forwarded to the primary

adapter.

Question:

Which protocols are load balanced with SLB and which ones are not?

Answer:

Only IP/TCP/UDP protocols are load balanced in both directions: send and receive. IPX is load balanced on the

transmit traffic only.

Question:

Can I team a port running at 100 Mbps with a port running at 1000 Mbps?

Answer:

Mixing link speeds within a team is only supported for Smart Load Balancing™ teams and 802.3ad teams, as

stated earlier.

Question:

Can I team a fiber adapter with a copper Gigabit Ethernet adapter?

Answer:

Yes with SLB, and yes if the switch allows for it in FEC/GEC and 802.3ad.

Question:

What is the difference between adapter load balancing and Microsoft's Network Load Balancing (NLB)?

Answer:

Adapter load balancing is done at a network session level, whereas NLB is done at the system application

level.

Question:

Can I connect the teamed adapters to a hub?

Answer:

Yes. Teamed ports can be connected to a hub for troubleshooting purposes. However, this practice is not

recommended for normal operation because the performance would be degraded due to hub limitations.

Connect the teamed ports to a switch instead.

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:

Can WOL work over a virtual adapter (team)?

Answer:

Wake-on-LAN functionality operates in an environment before the operating system is loaded. WOL occurs

when the system is off or in standby, so no team is configured.
