ever see a ping like this?
-
on a LAN I always expect them to be <1ms, or on a WLAN maybe 3ms, but it's usually consistent. This ramps up, and then drops back to where it should be.
-
Is this going across a VoIP phone or something that might have be a bottle neck?

It doesn't look any different than any other ping.... am I missing something?
Check out the ping times, it climbs from 1ms to 8ms and then drops back down to 1ms.
-
no, it's from a server to a network printer on a LAN.
-
I see that, but . . . it doesn't mean the issue is with the network, it could just be the device.
Or whatever its connected too.
-
Does the printer have a replaceable NIC? The hardware might be starting to crap out.
-
I mean that type of ping time isn't usually too much of an issue for a printer as long as it is receiving print jobs. It isn't like you are sending 100GB to a printer.
I have this gut feeling that your barking up the wrong tree here. Like @DustinB3403 said, I would suspect something is going on at the device level and I am not sure it is the NIC.
-
Ring buffer filling up likely.

Was he barking? or was he just inquiring to something that seemed like odd behavior?
-
The printer is working. I was just wondering if anyone else had seen that behavior before.

What do you think would be filling the buffer?

Ring buffers are tiny. It would be getting filled with ICMP caching or something of that nature.

hmmm... That network has 3 other printers of that same model and none of them act like that, so maybe there is something flaky going on in the hardware of that particular one.

What brand model?

Never seen anything like it - very interesting
Have you run pings to other devices on your network to eliminate some possibilities?
-
I've seen this before. Usually it's latency on the network causing fluctuation in ping times, when it's local. When it's remote, there are so many variables and links in the chain, as it were, it's hard to know where the issues lies exactly. But it could be latency, failing NIC, failing port, old cable in the wall causing issues, EMI, etc.

It could be a bad networking cable. Had an AS400 once that had huge problems because of a bad LAN cable.

It's a Zebra GK420d label printer. I can ping any other device on the LAN with pings <1ms.

It could easily be a bad patch cable. I've never seen one act like that, but who knows. It's cheap and easy to test.

Change the cable and go from there.
