Users report web connectivity problems on the server (10.1.1.10). Which IP SLA configuration captures the failure details through the network to resolve the issue?
Define the IP SLA operation:
Use an echo operation to ping the server.
Schedule the probe to send periodic pings to the server.
Configure the threshold or parameters (optional) to alert you when there are connectivity issues.
ip sla 1
icmp-echo 10.1.1.10
frequency 30 ! Frequency of probe (every 30 seconds)
timeout 5000 ! Timeout value for each probe (in milliseconds)
threshold 5000 ! Threshold to consider the ping as failed (in milliseconds)
ip sla schedule 1 life forever start-time now
I want to say that all answers are wrong, some more than others
for B and D, there is no "url" work in the command http get <url> so those are out.
For A and C, time out can not be less than 5000
and for A, freqency can not be less than 5.
So I go with C cause the router will not accept url command for B and D, nor the timeout for A and C, but at least for C, the frequency is correct and the incorrect timeout command wont be accepted and will default to 5000 ms
There is no "get url" command. I read in documentation older ios versions may have supported the get url http:// command. However not current.
Also frequency is 5 minimum (although in command line it shows 1-604800)
IOU1(config-ip-sla-echo)#fre
IOU1(config-ip-sla-echo)#frequency
IOU1(config-ip-sla-echo)#frequency ?
<1-604800> Frequency in seconds
IOU1(config-ip-sla-echo)#frequency 1 ?
<cr>
IOU1(config-ip-sla-echo)#frequency 1
%Error: frequency is less than timeout 5000 ms
IOU1(config-ip-sla-echo)#frequency 5
IOU1(config-ip-sla-echo)#
A and D have bad frequency. B has a bad get command.
B is a bad command
R1(config-router)#ip sla 1
R1(config-ip-sla)#http get url http://1.1.1.1
^
% Invalid input detected at '^' marker.
R1(config-ip-sla)#ip sla 1
R1(config-ip-sla)#http get http://1.1.1.1
R1(config-ip-sla-http)#
And D and A are bad commands
1(config)#ip sla 2
R1(config-ip-sla)#
R1(config-ip-sla)#ip sla 2
R1(config-ip-sla)#icmp-ech
R1(config-ip-sla)#icmp-echo 1.1.1.1
R1(config-ip-sla-echo)#frequency 1
%Error: frequency is less than timeout 5000 ms
R1(config-ip-sla-echo)#
Frequency is in seconds (default 60sec) = (Optional) Sets the rate at which a specified IP SLAs operation repeats.
timeout milliseconds is in milliseconds (Default 5000ms) == (Optional) Sets the amount of time an IP SLAs operation waits for a response from its request packet.
So based on above the timers look aggressive on D, so B might be better
Again, i do not think this is a high quality question, IP SLA seems not be used after an incident, it might be good idea to setup before issues arise.
I see your point but B isn't a valid command except for older ios versions
2(config-ip-sla)#
R2(config-ip-sla)#http get ?
WORD URL
R2(config-ip-sla)#http get
nevermind, question states "Users report web connectivity problems" so its B
