• SLB supports transmit load balancing. SLB also supports receive load balancing due to
assistance from the port trunking technology on the switch. However, SLB requires all
teamed ports be connected to the same switch (refer to Figure 4-19). As a result, SLB doesn’t
provide switch redundancy.

Dual Channel and Dynamic Dual Channel were developed to address the predicament of having
to choose inbound load balancing (SLB or 802.3ad) versus switch redundancy (NFT or TLB).
