Teaming with Hubs (for troubleshooting purposes only)

Hub Usage in Teaming Network Configurations

SLB Teams

SLB Team Connected to a Single Hub

Generic and Dynamic Trunking (FEC/GEC/IEEE 802.3ad)

SLB teaming can be used with 10/100 hubs, but it is only recommended for 
troubleshooting purposes, such as connecting a network analyzer when switch 
port mirroring is not an option. 

Hub Usage in Teaming Network Configurations

Although the use of hubs in network topologies is functional in some situations, it 
is important to consider the throughput ramifications when doing so. Network hubs 
have a maximum of 100Mbps half-duplex link speed, which severely degrades 
performance in either a Gigabit or 100Mbps switched-network configuration. Hub 
bandwidth is shared among all connected devices; as a result, when more 
devices are connected to the hub, the bandwidth available to any single device 
connected to the hub is reduced in direct proportion to the number of devices 
connected to the hub. 

It is not recommended to connect team members to hubs; only switches should be 
used to connect to teamed ports. An SLB team, however, can be connected 
directly to a hub for troubleshooting purposes. Other team types can result in a 
loss of connectivity if specific failures occur and should not be used with hubs. 

SLB Teams

SLB teams are the only teaming type not dependent on switch configuration. The 
server intermediate driver handles the load balancing and fault tolerance 
mechanisms with no assistance from the switch. These elements of SLB make it 
the only team type that maintains failover and fallback characteristics when team 
ports are connected directly to a hub.
