IP SLA DHCP keep on failing

[vyas.nilay]

Please help.. I am trying to troubleshoot an a possible issue with DHCP. 

I have setup my IP SLA but it is only 50% success and keep on failing with Over threshold.

I am not too good with IP SLA so I might be missing someinformations. 

RTT is too high but when I run the ICMP on the same host it is normal 1to 3 ms. 

Details:

IPSLA operation id: 2
Latest RTT: 8335 milliseconds
Latest operation start time: 15:37:23 NZST Wed Jun 17 2020
Latest operation return code: Over threshold
Number of successes: 17
Number of failures: 0
Operation time to live: Forever

Configuration:

ip sla 2
dhcp 10.7.19.11 source-ip 10.7.0.253
timeout 60000
threshold 6000
history buckets-kept 35
ip sla schedule 2 life forever start-time now

Please let me know if you require more information. 

Thanks,

Nilay.

Hello,

the IP SLA looks good actually. Try and change the threshold and timeout values:

ip sla 2
dhcp 10.7.19.11 source-ip 10.7.0.253
timeout 10000
threshold 10000
history buckets-kept 35
ip sla schedule 2 life forever start-time now

Sure I will make it 15000 as Threshold to see what happens.. 

Is there any way to log over the threshold respond?? as I can leave it and check if goes over the threshold. 

Thanks,

Nilay.

Hello,

you could create a reaction that would generate a syslog message. It don't think you can react to a threshold violation, but if you set the timeout and the threshold to the same value, it essentially reacts to both:

ip sla reaction-configuration 2 react timeout threshold-type immediate action-type trapOnly
