We have some remote wireless Mikrotik’s in which occasionally the Ethernet port goes from full duplex to half duplex which causes problems on our PTP links. Is there any way to monitor this remotely, I didn’t see anything in MIB via SNMP, but would be open to other ways to monitor an Ethernet Port Duplex setting.
Are these links auto-negotiated?
Lots of errors (collisions) on a link are an indication that the duplex could be wrong.
Yes auto-negotiated on both sides, generally runs in 100mbs FD, but occasionally one flips into HD. Maybe a bad cable running up the tower, but for now we just want to know when it happens so we can reset the port. We can monitor port speed via SNMP, but not duplex setting.
Has anyone figured out how to do this yet?
Thanks!
I ended up setting up logging on interfaces that emails me when there’s a change in any of the interface status. Would prefer a mib variable to use with my NMS, but for now this is better then nothing.
/system logging action
add email-start-tls=no email-to=email@address name=email target=email
/system logging
add action=email disabled=no prefix="" topics=interface
