Chapter 11 Configuring VLANs
Understanding VLANs
Figure 11-1 shows an example of VLANs segmented into logically defined networks.
Figure 11-1 VLANs as Logically Defined Networks
VLANs are often associated with IP subnetworks. For example, all the end stations in a particular IP
subnet belong to the same VLAN. Interface VLAN membership on the switch is assigned manually on
an interface-by-interface basis. When you assign switch interfaces to VLANs by using this method, it is
known as interface-based, or static, VLAN membership.
Note The switch does not support VLAN Trunking Protocol (VTP).
Traffic between VLANs must be routed. Switches that are running the metro IP access image can route
traffic between VLANs by using switch virtual interfaces (SVIs). To route traffic between VLANs, an
SVI must be explicitly configured and assigned an IP address. For more information, see the
“Switch
Virtual Interfaces” section on page 9-5 and the “Configuring Layer 3 Interfaces” section on page 9-22.
