FIGURE 19 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 20, 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.
