Scenario 4-D: A TLB Team Using Destination MAC Address Load-Balancing Method
Taking the concepts reviewed in “Scenario A-1: One Device Pings Another on the Same Layer
2 Network” in Appendix A, this section describes how TLB MAC addressed based load-balancing
functions.
Beginning at the point in Scenario A-1 where Blue/1.1.1.2 transmits the ping reply to Red/1.1.1.1,
Blue must decide whether to use network port B or E. Blue’s teaming driver calculates using the
MAC address of Red (A) because Red is the frame’s destination. Because a hexadecimal A is
equal to 1010 in binary, and the last three bits (010) are used to determine the transmitting network
port (refer to Table 4-11 – Two-port team), 010 is assigned to network port 1 (or the Primary
port). Therefore, when communicating with Red, Blue will always use the Primary port to transmit
frames.
If Blue transmits a frame to Yellow, the same calculation must be made. Yellow’s MAC address
is hexadecimal F, which is equal to 1111 in binary. Blue’s teaming driver will again use the last
three bits to determine which network port will transmit the frame. Referring to Table 4-11, for
a team with two network ports, 111 is assigned to network port 2 (or the Non-Primary port).
Therefore, when communicating with Yellow, Blue will always use the Non-Primary port to
transmit frames.
