Configuring VLANs

Supported VLANs

logical network, it contains its own bridge Management Information Base (MIB) information and can support
its own implementation of spanning tree.
Figure 3: 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.
Traffic between VLANs must be routed .
The switch can route traffic between VLANs by using switch virtual interfaces (SVIs). An SVI must be
explicitly configured and assigned an IP address to route traffic between VLANs.
Supported VLANs
The switch supports VLANs in VTP client, server, and transparent modes. VLANs are identified by a number
from 1 to 4094. VLAN IDs 1002 through 1005 are reserved for Token Ring and FDDI VLANs.
VTP version 1 and version 2 support only normal-range VLANs (VLAN IDs 1 to 1005). In these versions,
the switch must be in VTP transparent mode when you create VLAN IDs from 1006 to 4094. Cisco IOS
Release 12.2(52)SE and later support VTP version 3. VTP version 3 supports the entire VLAN range (VLANs
1 to 4094). Extended range VLANs (VLANs 1006 to 4094) are supported only in VTP version 3. You cannot
convert from VTP version 3 to VTP version 2 if extended VLANs are configured in the domain.
Although the switch stack supports a total of 1,000 (normal range and extended range) VLANs, the number
of configured features affects the use of the switch hardware.
