2 Configure the switch to add VLAN tag 103 and 104 to packets from the internal
networks and VLAN tag 105 and 106 to packets from the external networks and to
send packets from all of these networks to the FortiSwitch-5003A board.
vlan 103
name "VLAN103"
tagged 6,8,19,A1,A4
exit
vlan 104
name "VLAN104"
tagged 5,7,20,A1,A4
no ip address
exit
vlan 105
name "VLAN105"
tagged 6,8,19,A1,A4
no ip address
exit

3 Add spanning tree instance 3 for packets from the internal networks. Add VLAN
tags 103 and 104 to this spanning tree instance. Set the priority of this spanning
tree instance to 5.
spanning-tree instance 3 vlan 103 104
spanning-tree instance 3 priority 5
4 Add spanning tree instance 5 for packets from the external networks. Add VLAN
tags 105 and 106 to this spanning tree instance. Set the priority of this spanning
tree instance to 5, the same as instance 3.
spanning-tree instance 5 vlan 105 106
spanning-tree instance 5 priority 5
Example configuration for the FortiSwitch-5003A board in slot 1
The FortiSwitch-5003A board in slot 1 requires the following configuration
settings:
1 Disable communication between the FortiSwitch-5003A boards:
config switch fabric-channel physical-port
edit slot-2/1
set status down
end
2 Create an MSTP configuration that includes the same name and revision as was
added to the external switch. For example, if the name is tree_1 and the revision
is 1:
config switch fabric-channel stp settings
set name "tree_1"
set revision 1
end
