Hi my config is

interface Ethernet0/1
 ip address 162.1.6.6 255.255.255.0
 half-duplex
end

 ip sla monitor 10
 type udpEcho dest-ipaddr 162.1.6.255 dest-port 4000 source-port 8000 control disable
 timeout 1000
 frequency 2
ip sla monitor schedule 10 life forever start-time now

but router can't send broadcast udp packet

*Mar  2 06:16:55.156: IP: tableid=0, s=162.1.6.6 (local), d=162.1.6.255 (Ethernet0/1), routed via RIB
*Mar  2 06:16:55.156: IP: s=162.1.6.6 (local), d=162.1.6.255 (Ethernet0/1), len 44, sending
*Mar  2 06:16:55.160:     UDP src=8000, dst=4000
*Mar  2 06:16:55.160: IP: s=162.1.6.6 (local), d=162.1.6.255 (Ethernet0/1), len 44, encapsulation failed
*Mar  2 06:16:55.160:     UDP src=8000, dst=4000
