image

Just a few notes to help myself remember.

  • To use a serial connection (Cisco / Arista) attached to a server:
    sudo screen /dev/ttyS0 9600 (Where ttyS0 is the port it’s attached to)
  • ethtool – Because 10gig hates me:
    ethtool -s eth4 autoneg off speed 10000 duplex full
  • On a new switch, remember to enable spanning tree on the ports you’ll be using.
