Configuring auto topology

Starting in FortiSwitchOS 7.2.0, auto-network is enabled by default. After an execute factoryreset command is executed on a FortiSwitch unit in standalone mode, the auto-network configuration is enabled by default. If you are not using auto-network, you must manually disable it: config switch auto-network set status disable end

Use the auto topology feature to automatically form an inter-switch link (ISL) between two switches. You need to enable the feature and specify the mgmt-vlan. The mgmt-vlan is the VLAN to use for the native VLAN on ISL ports and the native VLAN on the internal switch interface.

NOTE: Do not use the same VLAN for the mgmt-vlan and an existing switch virtual interface (SVI).

config switch auto-network

set mgmt-vlan <1-4094>

set status {enable | disable}

end

For example:

config switch auto-network

set mgmt-vlan 101

set status enable

end

config switch interface

edit "internal"

set native-vlan 101

set allowed-vlans 100-102,4094

set stp-state disabled

set snmp-index 53

next

end
