Description | This article describes how to enable VTP under FortiSwitch as a Standalone and Managed by FortiGate. | ||||||||||||||||
Scope | FortiSwitch v7.0.5, v7.2.0 onwards. | ||||||||||||||||
Solution |
VTP (VLAN Trunking Protocol) is a Cisco protocol, its function is to create VLANs on the VTP Server that will allow create VLANs on all other Cisco Switches and will be synchronizing themselves, there are 3 components VTP Server, VTP Transparent, VTP Client, here a little table that can give us visibility about each component:
FortiSwitches cannot participate under the VTP topology as a Server or Client mode, which means if there is any VLAN change on Cisco Switches FortiSwitch will not synchronize its own VLAN database. If there is a FortiSwitch in the middle of the Cisco Switches topology, the FortiSwitch can act something like a Transparent mode, the transparent mode only Forwards. If the network topology requires VTP and blocking this communication is not an option, activate the forwarding VTP with the following commands under each FortiSwitch:
FortiSwitch # config switch global |
