      Pinging from a server that connects to a 24 port rack mount switch, then to a pair of wireless bridge, then to a 8 port rack mount switch.

      Switch maker said the ping delay from switch is not a issue with the switch, as long as the switch can pass traffic fine. I tend to disagree.

      Ping statistics for 192.168.1.33:
      Packets: Sent = 89683, Received = 89608, Lost = 75 (0% loss),
      Approximate round trip times in milli-seconds:
      Minimum = 2ms, Maximum = 2280ms, Average = 94ms

      In this separate test, I had a laptop plug directly to a 26 port rack mount switch, ping gets drop but switch maker said the switch is working in their environment.

      Tried 3 different cables, 3 different port on switch same result.

      In this separate test, nothing else is plug into the 8 port rack mount switch other than the laptop, switch was even reset to factory default, and I got this response. It goes to a cycle of 1ms then back up to ~400ms than back to 1ms and repeat.

        I'd immediately consider that the switch is going bad with traverse times like that.....

          Connect to the serial port and verify boot completed and all that. then start your pings.

          It is entirely possible it was still booting.

              We are having issue with multiple switches. Same make, different model of switches.

              @JaredBusch
              I am not on site. Can't do any complicated test other than the ping test batch file I am having the technician run.
              We took out the rack mount 26 port switch (picture of the laptop with the white cat5 connected to a switch) and put in a 24 port NetGear switch and these are the response. This test was with a full load on the NetGear switch while the picture above is just with one laptop plugged into it.

              Ping statistics for 192.168.1.1:
              Packets: Sent = 75002, Received = 75002, Lost = 0 (0% loss),
              Approximate round trip times in milli-seconds:
              Minimum = 0ms, Maximum = 3ms, Average = 0ms

              I think the switches in questions are just badly design/manufactured/programmed/whatever. Switch maker doesn't think so and told us their switch is working as design.

                Regarding that last screenshot.

                Connect to the serial port and verify boot completed and all that. then start your pings.

                It is entirely possible it was still booting.

                Yes that might be true; the ping times incrementally get larger until they go back to 1, at least in the screenshot, but not the posted wall of text.
                In the first wall of text ping times start high and go down slowly.
                In the last screenshot they start low and get higher til they all go back to 1.
                To me this is either something booting up, or a bottleneck somewhere.
                I might check the wireless stuff as a starting point.
