In Which Location Are The Normal Range Vlans Stored On A Cisco Switch By Default?

In which location are the normal range VLANs stored on a Cisco switch by default?

• ROM.
• Flash memory.
• Start-config.
• Setup-config.

Answer: The place where the normal range VLANs stored on a Cisco switch by default are in the file known as vlan.dat, which exists in the flash memory.

VLAN has a database in which the data stores like the VLAN ID, name, etc. local vlan.dat file is known as the default VLAN database location which is stored in the non-volatile memory or flash memory. The VLAN ID number 1 to 1005 configuration occurs in the vlan.dat and you can show them by typing the show VLAN privileged command in the command prompt. Normally the vlan.dat is stored in the flash but if the VTP mode is transparent it is also stored in the switch running-config.

To add or remove the ports from VLANs the interface configuration mode Is used which defines the port membership mode as well. All the commands results are written in the running configuration file. The steps to the switch configuration during the storage of VLAN and VTP data are listed in the following:

• The VLAN database is not considered when the VTP is in the transparent mode in the startup configuration, and also the VLAN and VTP domains from the database of the VLAN match within the startup configuration, and the configurator of the VLAN and VTP is used in the configuration file. While the revision number in the database remains unchanged.
• In case the domain names in the configuration file are not the same as the VLAN database, then the domain name, the VTP mode, and the VLAN ID 1 TO 1005 configurations use the data of the VLAN database.
• Versions 1 and 2 of the VTP, if the mode is server, then the configuration of IDs 1 to 1005 and the domains use the VLAN DB. data, while version 3 of VTP assist the VLANs 1006 to 4095 IDs.
