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
