What is VLAN transparent mode?
The VTP Transparent mode is something between a VTP Server and a VTP Client but does not participate in the VTP Domain. In Transparent mode, you are able to create, modify and delete VLANs on the local switch, without affecting any other switches regardless of the mode they might be in.
How do I set VTP to transparent mode?
VTP Modes
- Transparent—Allows you to relay all VTP protocol packets that it receives on a trunk port to all other trunk ports.
- Server— Allows you to create, remove, and modify VLANs over the entire network.
- Client— Allows you to create, change, and delete VLANs on the local device.
What is transparent mode?
Transparent mode is also known as bridge mode or transparent bridging mode. Transparent mode is used when the IT administrator does not wish to change the existing network layout. Normally, the existing network has already set up routers and switches. The firewall will be used as a security device.
What is VTP mode?
VTP server mode – the default mode for Cisco switches. A switch operating in this mode can create, modify, and delete VLANs. You can also specify other VTP configuration parameters on a VTP server, such as VTP version and VTP pruning, for the entire VTP domain. A VTP server switch will propagate VLAN changes.
How to configure private VLANs on Cisco switches?
This does not matter because the restrictions in communication will be imposed by the switch on Layer2 level. Before starting PVLAN configuration, switching VTP Mode to Transparent is required. If VTP works in other mode, PVLAN will not work. Setting device to VTP TRANSPARENT mode.
How to set VLAN ID in privileged exec mode?
This is important because the VTP server-configured switches are the masters of the VLAN information, and whatever VLAN configuration data has been configured in them will be distributed to the switches in VTP client and transparent modes. Within privileged exec mode, open the VLAN data and set the VLAN ID and name, using these commands:
What can you do with a private VLAN?
Private VLANs can be configured on the Catalyst 6000 and Catalyst 4000 series products. Within a private VLAN, you can isolate devices to prevent connectivity between devices within the isolated VLAN. Within a private VLAN, communities can be created to allow connection between some devices and to prevent them from communicating with others.
Can you use VTP version 3 for private VLANs?
In addition to supporting the concept of normal VLANs, VTP version 3 can transfer information regarding Private VLAN (PVLAN) structures. Because VTP versions 1 and 2 do not support private VLANs, you must manually configure private VLANs on all switches in the Layer 2 network.
