I'm sorry I didn't explain myself better. The switch is a couple of hops away. A wireless AP is at the SRX, then a media bridge after the wifi AP, then a switch stack, then servers. The 100 Mbps seemed to pass through or zero out a connection drop at the AP level. The SRX seems to drop purposely. I disconnected the 100mbps because it's always on even though the PC is off. It does sense WOL actions. But something's not right there I can tell. Wierd MB. Since setting the correct link mode, 100 full it probably will do it.
My question is????
Does oam control this failure. I've had positive results it would seem, but it's been only a short time.
oam -> link-fault-management ->
link-discovery
-->remote
I haven't tried the connectivity option.
I accept what you are saying about setting links to match at the AP
😀, but I still want to know about oam.
