FIGURE 21 Assigning ports to logical switches

A given port is always in one (and only one) logical switch. The following scenarios refer to the chassis
after port assignment in

Figure 21

:

• If you assign P2 to logical switch 2, you cannot assign P2 to any other logical switch.
• If you want to remove a port from a logical switch, you cannot delete it from the logical switch, but

must move it to a different logical switch. For example, if you want to remove P4 from logical switch
3, you must assign it to a different logical switch: logical switch 2, logical switch 4, or logical switch 1
(the default logical switch).

• If you assign a port to a logical switch, it is removed automatically from the logical switch it is

currently in. If you assign P3 to Logical switch 3, P3 is automatically removed from logical switch 2.

• If you do not assign a port to any logical switch, it remains in the default logical switch, as is the

case with ports 0, 1, 7, and 8.

Refer to

Adding and moving ports on a logical switch

on page 290 for instructions for assigning and

moving ports on logical switches.

A logical switch can have as many ports as are available in the chassis. In

Figure 21

, the chassis has

10 ports. You could assign all 10 ports to a single logical switch, such as logical switch 2; if you did
this, however, no ports would be available for logical switches 3 and 4.

You can move only F_Ports and E_Ports from one logical switch to another. If you want to configure a
different type of port, such as a VE_Port or EX_Port, you must configure them after you move them.
Some types of ports cannot be moved from the default logical switch. Refer to

Supported platforms for

Virtual Fabrics

on page 280 for detailed information about these ports.

Logical switches and connected devices

You can connect devices to logical switches, as shown in

Figure 22

. In logical switch 2, P2 is an

F_Port that is connected to H1. In logical switch 3, P4 is an F_Port that is connected to D1. H1 and D1
