112 | Configuring Interfaces

*The Default VLAN (VLAN 1) does not require creation, but it can be modified.
Physical and logical interfaces are automatically in Layer 2 mode. To place an interface in Layer 3 mode,
assign an IP address to that interface (see Configuring Layer 3 Mode on page 122). These interfaces also
contain Layer 2 and Layer 3 commands to configure and modify the interfaces.
Viewing Interface Information
S-Series (SFTOS) ports are configured for Layer 2 by default, so you do not need to explicitly configure
them as Layer 2, as you do on the E-Series (FTOS). Initially, the running configuration file simply displays
the series of ports without any configuration annotations. As you configure a
port, those changes appear in the running configuration following the affected port.
For example, Figure 7-76 shows part of a running configuration; it displays the configuration
for the series of ports numbered 1/0/45 through 1/0/48. Each port listing is followed by
no shutdown to indicate that each of these ports has been enabled.
