however if i do ping command
ping 1.1.1.1 source 2.2.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
Packet sent with a source address of 2.2.2.2
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 116/118/120 ms
ping is successful.
my questions what happened with SKA probe?
if i recreate test, test start workingip sla isn't work properly
