Dear guys,
Since a few weeks, we are experiencing high latency in our internal LAN:
- No VLAN's are in place.
- +/- 50 clients and phones (in total) are connected to our LAN.
- 2 HP 1920G's (they are replaced by HP because of my support ticket: troubleshooting).
The problem is intermittently: outside of business hours there is a little bit of latency: +/- 6 seconds sometimes to hosts on the same switch.
During business it went very well for several hours (+/- 3ms latency on hosts on the same switch), but another hour there is 300/400/500ms latency to hosts on the same switch.
- Loop Detection is enabled on the switches: no loops detected.
- All switches are on the newest firmware.
How can I troubleshoot this? I can work with wireshark, but it's very difficult for me to analyse/interpret this.
Where/how should I start to troubleshoot this?
Kind Regards,
Pieter
