HOWTO Upgrade an Extreme switch to 7.2.0b33 with ssh

  1. Requirements
    • Extremeware 6.2.2b56 or higher already on the switch
    • Hardware supported by ExtremeWare 7.20b33 (includes 'i' series Summits, BlackDiamond 6816/6808/6804 Alpine 3808/3804/3802)
    • These instructions have been tested against an Alpine 3808
    • Up to 10 minutes of downtime
    • Up to 20 minutes of human time
  2. Prepare to Upgrade
    • Upload ngboot81.bin and 720b33.Sxtr to a TFTP server
    • Save switch configurations
    • Backup the switch configuration (just in case)
  3. Upgrade BootROM to 8.1
    • Commands:
      • # download bootrom <TFTP-server> [<path>]/ngboot81.bin
      • # reboot
    • Wait about 1 minute for the switch to reboot, then relogin
    • Check that BootROM is 8.1
      • # show version
  4. Upgrade software to 7.2.0b33
    • Commands:
      • # download image <TFTP-server> [<path>]/v720b33.Sxtr
      • # reboot
    • Wait about 1 minute for the switch to reboot, then relogin
    • Check that you are now using 7.2.0b33
      • # show version
      • # show switch
    • Check configuration log for errors
      • # show log
    • Manually reinput erred configuration parameters (In my tests, there weren't any)
    • Save configuration
      • # save
  5. Generate an SSH key
    • Command:
      • # configure ssh2 key
      WARNING
      Generating new server host key This will take approximately 10 minutes and cannot be canceled. Continue? (y/n) y
    • It will them prompt you to enter in some random characters. Enter at least one line full and press enter twice. It will then generate a host key (approx 10 mins). The performance impact to the switch itself is minimal.
  6. Enable SSH
    • Command:
      • # enable ssh2 [ access-profile <access-profile> ] [ port <tcp_port_number> ]
    • e.g.
      • # enable ssh2 access-profile "UofW"
    • save the config
      • # save
  7. Disable telnet (optional)
    • Command:
      • # disable telnet
