|RTO - is retransmit time outs. |
- I would start with testing the Ethernet cables on the Swx.
- Then do a LAN sniffer test on that Swx with WireShark http://www.wireshark.org/ to see if any traffic issues can be determined.
- Could be a flaky port(s), cable, BAD NIC on a PC, malware, Swx Thermal issue, power issue etc.
Just another stupid saying...
