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.
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.
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.
