    Hi!

    I am just setting up some Arista 7050s. Can you tell me, which EOS version you are using?`

    At the moment, I have installed 4.16.7M. Would you upgrade to 4.18.5M or are there any problems with the newer firmwares?

    Thank you and best wishes

    V 4.20.x and newer drops support for 7050q switches. You can run the image, but it won't find any ports.

    Hi!

    Good to know... So the latest 4.18 should be optimal for 7050Qs - right?

    Hi!

    I just found the first problem with 4.18M (the latest 4.18, I could find):

    show logging follow
    --> does not give any output...

    bash sudo tail -f /var/log/messages
    --> is a workaround...

    Do you have any newer firmware, that does not have that problem, or did I miss something?

    Best wishes

    Also from what I remember through digging through the guts of EOS, show logging/show logging follow tails /var/log/eos - it's possible the command works but you just don't have any content there.

    to tail /var/log/messages like you are manually, that's "show logging system"

    Hi!

    Sorry for the late answer. I am using 4.18.5M
    tail /var/log/messages is working fine, but show logging follow does not.

    There seems to be some difference...

    "show logging follow" doesn't tail /var/log/messages, it tails /var/log/eos - try tailing that manually and see if there's actually anything there

    "show logging system" is the command that tails /var/log/messages

    Hi!

    Sorry, i did not describe the full problem. I just found some new things...

    show logging
    --> works

    show logging follow
    --> does not show anything, although new entries are written IF my putty-window is maximized / its width is larger than the longest line.
    --> does show the log, if the putty-windo is small...

    VERY strange...

    out of curiosity, what does "show logging system" do? does it properly show the stuff you were seeing in /var/log/messages?

    Yes, "show logging system" works - in full-screen and in small windows :)
