However, traffic received by the server is not load balanced, meaning the Primary teamed port is responsible for receiving all traffic destined for the server (refer to Figure 4-12). As with NFT, there are two types of team members, Primary and Non-Primary ports. The Primary port transmits and receives frames and the non-Primary ports only transmit frames.

Scenario 4-B: A Device Pings a TLB Team on the Same Layer 2 Network This section builds on the concepts reviewed in "Scenario A-1: One Device Pings Another on the Same Layer 2 Network" in Appendix A, and describes how TLB functions from the network addressing and communication perspective. Utilizing a network diagram similar to Figure A-1 in Appendix A, Blue has been modified to be a server utilizing an HP Integrity Network adapter team in TLB mode with two network ports in a team (refer to Figure 4-13). The two network ports have Layer 2 addresses of MAC B and MAC E, respectively, and are known by a single Layer 3 address of 1.1.1.2. Network port B has been designated as the Primary port in this TLB team. 58 The Mechanics of Teaming for the Advanced User
