Configuring Normal-Range VLANs

Default Ethernet VLAN Configuration

Table 14-2
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.
When the switch is in VTP transparent mode and the EI is installed, you can assign VLAN IDs greater
Note
than 1006, but they are not added to the VLAN database. See the
VLANs" section on page
For the list of default parameters that are assigned when you add a VLAN, see the
Normal-Range VLANs" section on page
