Random Ping times issue, Any help please!!!

[tobiasclarity]

Hi All,

 

I just wondered if anyone can throw some ideas in over this issue we currently have,

 

We noticed some while back that one of our main switches in another building had been getting random ping times, it never seemed to stabilize in the sense regardless of high user load or barley anyone in the building (during holidays) as such and for works that needed doing anyway we had the Fibre replaced going from our core to said building with a nice shiny SM. Unfortunately the problem still existed. We have now due to other reasons been in a position where we could replace the switch in the building with a new replacement, so in theory now no problems right? nope still an issue we have now got a brand new fibre and a brand new switch and we are still getting random ping times (See attached)

 

This is all HP kit and fibre was tested and certified on installation by company that installed it

 

Any ideas to try would be gratefully received

 

 

Any of our other switches in other buildings all give a nice solid <1ms response straight down the line, with not much difference in setups as we have ruckus WIFI for example across the whole site again this is on other switches so cant be that.

Sounds daft, but do you get the same response if nothing is plugged in to the switch apart from your fibre uplink?

 

Can't work it out from your post whether you've done that or not.

 

If you have, it could of course be one of the fibre modules on either end if you haven't replaced them.

Well just to add more confusion i tested it without anything plugged in apart from the fibre and we were still seeing the same, also they are brand new gbics on both sides

Could it be a faulty fibre patch cable?

or Fibre Adapter Panel (FAPs) we had one the other day.

Switches don't exactly give ping traffic to themselves high priority, this is not uncommon behaviour. Worry if you get similar random pings to connected devices, but if you're getting a solid 1ms (according to Windows) to devices then don't worry at all.

Are you pinging the actual switch or a device plugged into the switch?

 

If you are pinging the switch it doesnt surprise me at all

 

Does it happen to a device as well or just the switch?
