5.
Check that the adapters and the switch are configured identically for link
speed and duplex.
6.
If possible, break the team and check for connectivity to each adapter
independently to confirm that the problem is directly associated with
teaming.
7.
Check that all switch ports connected to the team are on the same VLAN.
8.
Check that the switch ports are configured properly for Generic Trunking
(FEC/GEC)/802.3ad-Draft Static type of teaming and that it matches the
adapter teaming type. If the system is configured for an SLB type of team,
make sure the corresponding switch ports
are not
configured for Generic
Trunking (FEC/GEC)/802.3ad-Draft Static types of teams.
Frequently Asked Questions
Question:
Why am I unable to obtain network settings through DHCP using
PXE?
Answer:
For proper operation, make sure that the STP is disabled or that
portfast mode (for Cisco) is enabled on the port to which the PXE
client is connected. For instance, set spantree portfast 4/12 enable.
Question:
Under what circumstances is traffic not load balanced? Why is all
traffic not load balanced evenly across the team members?
Answer:
The bulk of traffic does not use IP/TCP/UDP or the bulk of the clients
are in a different network. The receive load balancing is not a function
of traffic load, but a function of the quantity of clients that are
connected to the server.
Question:
What network protocols are load balanced when in a team?
Answer:
Cavium’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 100Mbps with a port running at
1000Mbps?
Answer:
Mixing link speeds within a team is only supported for Smart Load
Balancing teams and 802.3ad teams.
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.
