Hi all,
I recently configured an sx350x-24F and have come up against a weird issue when plugging in workstations into the non-combo ports.
When plugging in the SFPs and having informational logging enabled I can see the switch acknowledge the fact that the SFPs have been inserted and the switch changes the speed of the port to 1Gb, matching the speed of the SFP. When connecting a workstation I can see the link light on the 1Gb fibre network card and the activity light start blinking as the workstation attempts to negotiate with the switch. The switch, however, does nothing. No logging messages, nothing on the ‘show int status’ command, no interfaces listed as err-disabled. The link light on the workstation NIC remains lit and Windows eventually gives up trying to 'identify' the network. When connecting a printer through a 1Gb copper-fibre media converter, the port comes up, the switch shows a logging message and the port forwards traffic, everything works as expected. Very weird. Any ideas why the switch might be ignoring the workstation?
When plugging a workstation into the combo ports ports, they work as expected. Logging messages, traffic, the whole nine yards. All configuration on these combo ports are identical to the other ports on the switch. This leads me to think that the hardware used on the non-combo ports must be different and thus negotiate differently somehow. Maybe? All configuration across these ports is the same, they're just access ports configured to a VLAN.
I’ve tried hard-coding speed, duplex, flow control, errdisable configuration for link-flapping, disabled the auto-voice LAN configuration, played around with the green-ethernet settings, tried setting the ports from access to general to customer ports and seeing if that makes a difference, updating the firmware on the switch and setting the workstation NIC to not go to sleep, and a whole host of other things but no dice.
Can anyone think of anything that I might be missing? Any help would be much appreciated. Thank you.
