I have found an issue (maybe related to this thread as well) - whenever I change RSTP settings (port priority in my case, BUT on different port, not on SFP!) then SFP port goes down/up for about 3-4s. Is it expected behaviour?

Code: Select all

I filed a bug report about this last year.

This started happening around mid 1.5.

Also happens if I do any VLAN changes. Problem presists even with STP disabled.
