Using the BayStack 380 10/100/1000 Switch
Figure 30 shows two trunks (T1 and T2) connecting Switch S1 to switches S2
and S3.
Figure 30 Switch-to-switch trunk configuration example
You can configure each of the trunks shown in Figure 30 with up to four switch
ports to provide up to 8 Gb/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 31 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 card (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.
