Chapter 15 Configuring VLANs Configuring Normal-Range VLANs
In VTP versions 1 and 2, if VTP mode is server, the domain name and VLAN configuration for only
the first 1005 VLANs use the VLAN database information. VTP version 3 also supports VLANs
1006 to 4094.
Default Ethernet VLAN Configuration
Table 15-2 shows the default configuration for Ethernet VLANs.
Note The switch supports Ethernet interfaces exclusively. Because FDDI and Token Ring VLANs are not
locally supported, you only configure FDDI and Token Ring media-specific characteristics for VTP
global advertisements to other switches.
Creating or Modifying an Ethernet VLAN
Each Ethernet VLAN in the VLAN database has a unique, 4-digit ID that can be a number from 1 to
1001. VLAN IDs 1002 to 1005 are reserved for Token Ring and FDDI VLANs. To create a normal-range
VLAN to be added to the VLAN database, assign a number and name to the VLAN.
Note With VTP version 1 and 2, if the switch is in VTP transparent mode, you can assign VLAN IDs greater
than 1006, but they are not added to the VLAN database. See the “Configuring Extended-Range
VLANs” section on page 15-10.
For the list of default parameters that are assigned when you add a VLAN, see the “Configuring
Normal-Range VLANs” section on page 15-4.
