Changing the base control subnet and VLAN
You can change the base control subnet and VLAN from the FortiController CLI. For example to change the base control subnet to 10.122.11.0/255.255.255.0 and the VLAN ID to 320:
config load-balance setting
set base-ctrl-network 10.122.11.0 255.255.255.0
config base-ctrl-interfaces
edit b1
set vlan-id 320
next
edit b2
set vlan-id 320
end
end
If required, you can use different VLAN IDs for the B1 and B2 interface.
Changing this VLAN only changes the VLAN used for base control traffic between chassis. Within a chassis the default VLAN is used.
