Link down errors
-
I just had a "link down" failover event that occurred. So I rebooted the ISP equipment and that didn't resolve it. I rebooted pfSense and that resolved the issue. Had a whole bunch of these (about 1000 since I show the last 1000 events in the web UI) in the system log:
Jun 28 22:30:35 kernel: arpresolve: can't allocate llinfo for 68.197.64.1 on em3
Jun 28 22:30:35 kernel: arpresolve: can't allocate llinfo for 68.197.64.1 on em3
Jun 28 22:30:34 kernel: arpresolve: can't allocate llinfo for 68.197.64.1 on em3I had tried releasing and renewing the DHCP address on this link, and the web UI wouldn't reload until I clicked on the refresh button in the browser.
68.197.64.1 is the gateway, and 8.8.8.8 is the remote IP that the link monitors. My configuration is in my signature.
This is with pfSense 2.2.3 AMD64.
