The FortiGate-5001D can’t join a FortiController-5903 SALB cluster and other
fabric backplane communication problems
In some SALB configurations and with some firmware builds you may have to manually
set the speeds of FortiGate-5001D interfaces that connect to the fabric blackplane (for
example, elbc-ctrl/1 and elbc-ctrl/2). Normally the speeds of these interfaces are set to
auto and normally this would work. But in some cases you have to set these interface
speeds to 40000full if the cluster is installed in a FortiGate-5144C chassis or 10000full if
the cluster is installed in a chassis with a 10-gbyte backplane (such as the FortiGate-
5060 of 5140B). If you have issues with the FortiGate-5001D communicating with the
fabric backplane you can use the following CLI command to change the speeds of these
interfaces:
To set the speed to be compatible with a 40-gbyte backplane:
config system interface
edit elbc-ctrl/1
set speed 40000full
next
edit elbc-ctrl/2
set speed 40000full
end
To set the speed to be compatible with a 10-gbyte backplane:
config system interface
edit elbc-ctrl/1
set speed 10000full
next
edit elbc-ctrl/2
set speed 10000full
end
