    mellanox switch SN2700 extremely slow login

    ctmoore

      My question is: How can I fix this slow login? Does it need new firmware or software, or...?

       

      We have a Mellanox 100Gb switch (SN2700) that is extremely slow to login via ssh.  Eg:

       

      root@local:~# ssh admin@sw100

      Once logged in, it's perfectly fine/responsive as expected. It also appears to work just fine for the servers connected to its ports. My thought is that it might need some

      type of update on software or firmware?  show version gives me:

      I would appreciate any comments or feedback.

       

      PS I placed this in Mellanox OFED for lack of a more obvious (or allowed!) place; if there's somewhere else more suitable

      for this question, please let me know where and I will move the question.

       

      Thanks,
