already assigned FID 15 in the chassis. Each Logical Switch must have a unique fabric ID within the chassis. The default Logical Switch is initially assigned FID 128. You can change this value later. Physical chassis Logical switch 1 (Default logical switch) (FID = 128) Logical switch 2 (FID = 1) Logical switch 3 (FID = 15) Logical switch 4 (FID = 8) Logical switch 5 (FID = 20) Figure 10 Fabric IDs assigned to Logical Switches Port assignment in Logical Switches Initially, all ports belong to the default Logical Switch. When you create additional Logical Switches, they are empty and you must assign ports to those Logical Switches. As you assign ports to a Logical Switch, the ports are moved from the default Logical Switch to the newly created Logical Switch. A given port can be in only one Logical Switch. In Figure 11, the default Logical Switch initially has 10 ports, labeled P0 through P9. After Logical Switches are created, the ports are assigned to specific Logical Switches. Note that ports 0, 1, 7, and 8 have not been assigned to a Logical Switch and so remain assigned to the default Logical Switch. Before port assignment After port assignment Logical switch 1 (Default logical switch) P0 P2 P4 P6 P8 P1 P3 P5 P7 P9 Logical switch 2 Logical switch 1 (Default logical switch) P0 P1 P7 P8 P2 Logical switch 2 P3 Logical switch 3 P4 P9 Logical switch 3 P5 Logical switch 4 P6 Logical switch 4 Figure 11 Assigning ports to Logical Switches A given port is always in one (and only one) Logical Switch. The following scenarios show the chassis after port assignment in Figure 11. • If you assign P2 to Logical switch 2, you cannot assign P2 to any other Logical Switch.
