Default Ethernet Vlan Configuration - Cisco Catalyst 3750 Software Configuration Manual

Configuring Normal-Range VLANs
When you save VLAN and VTP information (including extended-range VLAN configuration
information) in the startup configuration file and reboot the switch, the switch configuration is
determined in these ways:
•
•
•
Caution If the VLAN database configuration is used at startup and the startup configuration file contains
extended-range VLAN configuration, this information is lost when the system boots up.

Default Ethernet VLAN Configuration

Table 10-2
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.

If the VTP mode is transparent in the startup configuration, and the VLAN database and the VTP
domain name from the VLAN database matches that in the startup configuration file, the VLAN
database is ignored (cleared), and the VTP and VLAN configurations in the startup configuration
file are used. The VLAN database revision number remains unchanged in the VLAN database.
If the VTP mode or domain name in the startup configuration does not match the VLAN database,
the domain name and VTP mode and configuration for the first 1005 VLANs use the VLAN
database information.
If VTP mode is server, the domain name and VLAN configuration for the first 1005 VLANs use the
