SG300-28P (SRW2024-K9) in L3 mode. Intermittent loss of speed

[sveinskogen]

Every "once in a while" (about a week with my network load), the SG300 crawls to an almost standstill of all IPv4 activity (haven't got IPv6 enabled here yet, so I can't comment wether this applies to IPv6 as well). It seems pure L2 transmissions is not affected, but L3 definitely is (down to 20mbit as opposed to the 600+ rate I usually get).

Soft-rebooting the switch (via the webgui) helps, and the intervals of the crashes seem related to total bytes transmitted, not time. I have jumbo frames enabled, and disabled flow control on on the switch and all hosts.

We have made major changes and fixed a lot of bugs since that version of firmware.

There really is no reason not to upgrade, you get more features and things get fixed.  Also, if you do need to call for technical support, it will be the first thing we do anyway.  We don't spend a lot of time troubleshooting old firmware.

Go ahead and upgrade to the latest when you get a chance, make sure to upgrade the bootcode as well.
