Logical switch overview 10

FIGURE 20 Switch before and after enabling Virtual Fabrics

After you enable Virtual Fabrics, you can create up to eight logical switches, depending on the

switch model.

Figure 21 shows a Virtual Fabrics-enabled switch before and after it is divided into logical switches.

Before you create logical switches, the chassis appears as a single switch (default logical switch).

After you create logical switches, the chassis appears as multiple independent logical switches. All

of the ports continue to belong to the default logical switch until you explicitly move them to other

logical switches.

The default logical switch always exists. You can add and delete other logical switches, but you

cannot delete the default logical switch unless you disable Virtual Fabrics.
