In this example, File server 1 uses dual MAC addresses, with one MAC address for each Network Interface Card (NIC). No multilink trunk is configured on File server 1. File server 2 is a single MAC server (with a four-port NIC) configured as multilink trunk configuration MLT1.
The following illustration shows a typical switch-to-server multilink trunk configuration.
In this example, one port on File server 1 is blocked and unused and File server 2 benefits from aggregated bandwidth on multilink trunk T1.
