Difference between ICMP Echo and UDP Echo.

Hi guys,

Can anyone tell me what is the exact difference between ICMP Echo and UDP
Echo ?

When configuring IP SLA, whats the difference between :

*#ip sla monitor 1*
*#type udpEcho dest-ipaddr x.x.x.x dest port yyyy*
*
*
*and*
*
*
*#ip sla monitor 1*
*#type echo protocol ipIcmpEcho x.x.x.x*
*
*
Thank you.
