I have a Dec740 that has a device plugged into port 0. with 2 different cables the led's randomly turn off on the appliance, and the device gives a pop up message saying network lost.
where can i find logs to troubleshoot this.
couple of Questions:
- "...randomly turn off on the appliance..." Do you mean that when the interface goes down, which device turns off, the DEC740 or the attached device?
- Is this copper cable? What CAT 5/6/7? How long is this cable?
- When did this issue start or is this the 1st time?
you can ssh to the DEC740 drop into the shell and cd to /var/log and look at the messages file and/or others to see what's going on. you can do this in the GUI under System Log files.
the network lights on the Dec actually turn off. this is 2 different 5 foot cables to my Apple Tv. i am going to try an actual switch this weekend to see if its the device itself. its only 2 months old though..
the Tv then shows network disconnected every 15 seconds or so.
honestly it happened when i installed 26.7 to see how it was. since then i have gone back to a snapshot of 26.4 but it still occurs
I recommend moving that device to another port and see what happens.
thats my plan
are there logs anywhere i can check for potential hardware failures or similar?
#dmesg | more
you can also look into the /var/log/ directory
Dmesg should show up/down and I'm supposing this is about igc?
# ifconfig igc1 | grep media
media: Ethernet autoselect (1000baseT <full-duplex>)
If it negotiates 2500 in auto mode this may be an issue. Check the right interface.
Cheers,
Franco
I haven't had much time in front of the issue, but I did run these commands. DEC 740 port 0 is the one having the issue / igc0

2nd command :
media: Ethernet autoselect (1000baseT <full-duplex>)
root@OPNsense:~ # ifconfig igc0 | grep media

Do you see the flip flops when setting igc0 on 1000baseT ?
Is the appletv nic flopping if connected to the USW-pro-8 ? Try both auto negotiation and static on the switch side
