The switch is also set to Auto on all ports: Auto Speed, Auto Duplex, Flow Control enabled. I checked all the devices where I can see/set the network options and they all are on Auto. Looking at the graph for incoming traffic and the detailed counters on the interfaces (like excessive incoming broadcasts/multicasts) might confirm this. It doesn't have to be a loop, it could also be from aggressive scanning of the network or maybe a camera streaming multicast (and the switch not doing IGMP snooping to only send to interfaces joining the stream).Īctually GE3 looks a little lower, which could mean that this is the source of the BUM traffic (BUM is sent to all interfaces except the one that it came in on).

If there is a loop it would usually slowly grow until you reach the limit in the loop (like physical interface speed, configured BUM rate limit on an interface or CPU on a software bridge). It looks like you have a little over 10 Mbps of BUM traffic that is going out on all interfaces (it maxes out the 10 Mbps interface and is a little over 10% on the 100 Mbps interfaces - that would be a little over 1% on gigabit which could match the graph, but it is too small to verify). There is nothing fancy configured, no VLAN, no QoS, etc.Īny idea what I can do to narrow this down?įrom the TX in the image I assume that it is showing outgoing traffic on the interfaces.

I have the Gigabit switch to which these devices are all directly connected: Pinging the OpenSprinkler results in lots of packet loss.Starting a file copy from/to my server suddenly slows to a crawl.Pinging the OpenSprinkler works fine, no packet loss.Sometimes file transfers to my server slow to a crawl resulting in hours to copy 1 GB of data compared to the usual seconds. Pinging the OpenSprinkler from other devices on the LAN results in lots of packet loss. It is this way regardless of STP enabled or not. It still should not(?) use excessive bandwidth like seen here: Connected to GE16 is an OpenSprinkler which only has a 10 Mbit/s interface. Its syslog seems better to me and I wanted to rule out the Cisco. In the meantime I replaced the Cisco switch with a DrayTek G2280x. Thanks, maybe I am searching in the wrong direction, I’m not sure. I was playing around with the Cisco (SG-200) settings, switching Spanning Tree Protocol settings, etc., but it stil occurs… I even was suspecting the Pi-hole running on a Raspberry Pi 4 Model B and connected via Ethernet, but their support is, of course, absolutely right when they say it could hardly be caused by the Pi-hole since all it does is DNS resolving. Of course I am reluctant to equip every single machine with this adapter since I do not know why this works and they are expensive. It seems to fix this behaviour which is really weird. I think it is safe to rule out a hardware defect, since it is happening with several Macs and macOS versions and in several locations.įot testing purposes I have equipped some Macs with a Thunderbolt Ethernet Adapter and disabled the internal Ethernet.
I even replaced the Cisco switch in one location to no avail.

At first I suspected a problem with the router/internet access, but when this problem occurs not only do I get packet loss pinging webservers, but local hosts/IPs!Ĭ) disable Ethernet via System Preferences, then enable againĭ) changing the configuration in Sys Prefs/Network/Hardware from automatic to manual or vice versaĮ) remove the Ethernet cable for a few secondsĪll of these reset the network connection enough to get back normal behaviour, but the problem will occur again in hours/days. In all cases the system itself is responsive and usable, but pinging other local devices on the LAN results in lots of packet loss. Others are just user machines where suddenly surfing the web becomes slow and unresponsive (web sites do not load, YouTube videos stall, etc.). Some of these Mac minis are used as file servers, so it usually gets visible when users start complaining that they have been disconnected from the fileserver. They all use the bulit-in Gigabit Ethernet port and have the following behaviour in common:Īfter a while of use (can be hours to days) they begin to drop packets. Most of them are on macOS Catalina 10.15.7, some are already running macOS Big Sur 11.2. I happen to support several Mac mini Late 2014 and iMacs from 2015. I have a strange problem to which I haven’t found a solution yet.
