Nortel Networks 450 manual Client/Server Configuration Using MultiLink Trunks

Using the BayStack 450 10/100/1000 Series Switch

You can configure each of the trunks shown in Figure 1-38 with up to four switch ports to provide up to 800 Mb/s aggregate bandwidth through each trunk, in full-duplex mode. As shown in this example, when traffic between switch-to-switch connections approaches single port bandwidth limitations, creating a MultiLink Trunk can supply the additional bandwidth required to improve the performance.

Figure 1-39 shows a typical switch-to-server trunk configuration. In this example, file server FS1 uses dual MAC addresses, using one MAC address for each network interface controller (NIC). For this reason, FS1 does not require a trunk assignment. FS2 is a single MAC server (with a four-port NIC) and is set up as trunk configuration T1.

Client/Server Configuration Using MultiLink Trunks

Figure 1-40 shows an example of how MultiLink Trunking can be used in a client/server configuration. In this example, both servers connect directly to switch S1. FS2 is connected through a trunk configuration (T1). The switch-to-switch connections are through trunks (T2, T3, T4, and T5).
