and this is a test from 3750e -> CCR 1009 over SFP+ port :

Sending 1000, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:

Success rate is 100 percent (1000/1000), round-trip min/avg/max = 1/3/34 ms

and also i do the same test over ethernet cable (connect CCR1009-Ethernet1 -> Cisco 3750e Ethernet 1) and result was same.

i ask this from mikrotik support they told me this is not critical but it should be solved before use it in production environment and they suggest me upgrade mikrotik to latest firmware and i did that but result was same! after many emails they told me its better ask cisco support because this issue is not related to their product.
and in these tests i change my 3750e-48td-s to another device (i have 2x 3750e-48td-s) and again result was same.
i also change transvier in 3750e-48td-s to another modules and result was same again.
so my question is :

1. is these pings are normal for point to point pings ?
2. in this situation can i use these routers and switches under production environment?

thanks,

Hello,

I might be missing your point, but there is no packet loss, and response time seem ok ?

Either way, what is the uptime of the Cisco switch ? If it has been up for a long time (> 1 or 2 years), it can become slow to respond...

Post the 'show version' of the Cisco....

Hi

yes there is no packet loss the only issue is ping time is between 0~5ms and sometimes there is one packet with 50ms OR 100ms after 50-100 packet with 0~5ms

so i want know is it normal or not?

and my cisco uptime is 3 hours right now because i do not use this device under productuion enviroment. i want fully test it before use it in productuion enviroment.

as you see my ping soutputs are they fine and ok for productuion enviroment ? (because sometimes there is 1 packet woith 100ms ot 50mb ) and in point to point ping (from router to switch or vice versa) my max ping time is around 30ms (you can see output in first post)

Hello,

I don't think it's a problem. ICMP traffic is treated as low priority. That said, post the output of ''show proc cpu' to make sure there are no processes hogging CPU resources...

blackmetal · ‎09-27-2017

here is the output of show proc cpu :

Switch>show proc cpu
CPU utilization for five seconds: 7%/0%; one minute: 7%; five minutes:

so in this situation your idea all things is fine and i can use this router and switches under production enviroments right? there is nothing critical and ping times are normal for point to point ping?

thanks,

Georg Pauwen · ‎09-27-2017

Hello,

you should be fine. CPU utilization is low. The PING responses might simply be due to Mikrotik and Cisco using different default ICMP packet sizes...

blackmetal · ‎09-27-2017

so your idea is allthings is fine and we can use this in production network without problem?

thanks

Georg Pauwen · ‎09-27-2017

Your question was about the PING response times. Those are not a problem when deloying the switch. I don't know anything else about your hardware, such as where and when you purchased it, if you have a service contract etc.
