R5#show ip sl summary IPSLAs Latest Operation Summary Codes: * active, ^ inactive, ~ pending ID Type Destination Stats Return Last (ms) Code Run ----------------------------------------------------------------------- *5 udp-jitter 6.6.6.6 RTT=6 OK 0 seconds ago ---- LOCAL: ip sla 5 udp-jitter 6.6.6.6 5000 threshold 1000 timeout 2000 frequency 2 ip sla schedule 5 life forever start-time now ----- REMOTE: ip sla responder

A is corerct

The answer is A. IP sla responder command is all that is needed. Only reason to use ip sla responder udp-echo ipaddress “ip” port “portnumber” command is when protocol control is turned off manually. It’s on by default.

I labbed this again as it is in the quesiton. A did not give a response but C did

changed my mind it is D, Labbed it again the exact way it is done here

if you specify a different port on the responder to the initiator it does not work. But if you just have #ip sla responder with no port that will work. You can match the port of the initiator which also works....so it is A

I labbed it in GNS3, A works

A is the answer for sure

One point I should mention is that the IP SLA Responder is not required for IP SLA to function, but it does allow for more detailed information gathering and reporting. https://learningnetwork.cisco.com/s/blogs/a0D3i000002SKN0EAO/ip-sla-fundamentals

I tested option A and option C option A is correct

option A , i test in my lab

Sorry for previous post, the ip address in answer "C" is incorrect. An ip address on R1 should be the destination IP for the reflected UDP traffic.

Based on the output, they want to measure udp-jitter. To configure IP SLA responders for UDP jitter use: #ip sla responder udp-echo ipaddress <> port <>

I just labbed it and the out come is C

i think you only need one line of command to enable ip sla responder. A for me

I'm voting A, too lazy to lab it tho haha

C doesn't work at all for some reason. I did notice that it is udp-jitter on one side and udp-echo on the responder side. However, I tried with the udp-echo as well and the C alone still doesn't work. It must be A then
