Example active-active redundant link configuration
Verifying the spanning tree configuration of a FortiSwitch-5003A board in slot 1
66
You can make the previous example an active-active redundant link configuration
that sends all traffic from the internal network to one FortiSwitch-5003A board and
all traffic from the external network to the other FortiSwitch-5003A board by
changing the priorities of the spanning tree instances added to the
FortiSwitch-5003A boards.
To send all traffic from the internal network to the FortiSwitch-5003A board in
slot 1 configure the spanning tree instances on this board with a lower priority
value for instance 3 which is used for VLAN 100 packets.
config switch fabric-channel stp instance
edit 3
set priority 4096
set vlan-range 100
next
edit 5
set priority 40960
set vlan-range 101
end
To send all traffic from the external network to the FortiSwitch-5003A board in slot
2 configure the spanning tree instances on this board with a lower priority value for
instance 5 which is used for VLAN 101 packets.
config switch fabric-channel stp instance
edit 3
set priority 40960
set vlan-range 100
next
edit 5
set priority 4096
set vlan-range 101
end
