Log link up/down count in XS1930-12HP

peos42

Hi

I can see in my syslog that my XS1930-12HP has logged two 10Gbit fiber link down events on SFP+ port 12. I guess my ISP patched or did reboot by any reason.

My question here is if it is possible to see in the switch how many link down events that has occurred since port stats was cleared. I cannot see/find it. Looking around in the CLI but cannot find anything related to this. I can in the "show interfaces status" see the port uptime, but not how many link down events if there were more than one. Is it only possible to count manually by looking into the switch log or do the following from my syslog server:

 egrep "interface: Port 12.*link down" /var/log/switch0|wc -l

Usually it should be possible to see on an interface statistics.

Tnx
Peo

Hi @peos42

After checking, the current method we can do is to count by the event logs.

I have created the idea post of this requirement:

We will monitor the comments and votes of this idea to evaluate.

Tnx for your reply @Zyxel_Melen Ok, so according to your answer I guess it is not possible today? My question was because most other switches have "Number of link down events" or similar on the port statistics.

Just thought is was there, somewhere, but that I did now how to retrieve it. But now I see it is not possible…

Would be a "nice to have" info in the port stats in the future…. Not a priority thing though as it is possible to "solve the issue" without it (as I showed in my question post above).
