Error when attempting to issue show packet-counters command

gabacho4

The outout I get invoking your suggested command is:

I tried the normal command once more for kicks and still get the error I reported earlier. Also, an running an up to date 20.1-1 instance in an SG-5100 just have all the variables.

1 ip4-input ip4 ttl <= 1

I bet it's that.

Are there really missing line breaks in a couple places there? Or was that just a copy/paste issue?

Screenshot from my phone just to avoid any copy and paste format fun.

gabacho4

Sorry about those breaks. I hadn't noticed them when I copied from the terminal.

jimp

That's OK, I figured it was just a copy/paste issue but wanted to be certain.

I'll work that info into a bug report, thanks!

gabacho4

Thanks for your understanding. So I've helped find a bug? Cool deal. Glad I could contribute to the cause. Any idea how long you think that one would take to correct? I'm not sure where it would fall on your list of priorities. In the meantime, I can always run the command you suggested. Pleasure interacting with you yet again!

jimp

Actually it looks like we already had one open for that. It's slated to be fixed in our next release (20.06) which isn't too far off.

In the meantime, you can run the vppctl version of the command to get the output.

Way to make a guy feel redundant

@gabacho4 - Thanks for all the great feedback and questions!

gabacho4

@audian no problem at all! I'm enjoying the TNSR experience and look forward to seeing the fixes and improvements you all are working on.
