today I have been upgrade my fortigate 601E to FortiOS version 6.4.5. I want to run command #exe ping-options source but after I check on CLI fortigate I can't perform that command.
Could you give me information regarding this case ?
Likely your HA is a-p. Then it might be intentional or as a result that none of interfaces is operational on the secondary unit. Or, no point pinging from the secondary.
