Brocade ICX/VDX firmware update cheatsheet

Wednesday, July 11th, 2018

Kind of a cheatsheet for updating firmware on Brocade’s ICX (nowadays Ruckus Networks) and VDX (nowadays Extreme Networks) switches.


– Make sure to check the release notes to ensure that your model is supported. For example, with ICX6xxx switches (which are EOL though) 08.0.30 branch is the highest you can go. 08.0.60 or 08.0.80 don’t support ICX6xxx.

  1. copy scp flash /home/brcdsup/fastiron/08030/ICX64S08030s.bin primary

– If you immediately get ‘Connecting to remote host… Connection Closed’ error, then check whether your SSH server config includes legacy options (to be added into sshd_config file):

  1. KexAlgorithms diffie-hellman-group1-sha1,,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1
  2. Ciphers 3des-cbc,blowfish-cbc,aes128-cbc,aes128-ctr,aes256-ctr


– Version upgrades such as 6.0 to 7.0, or 7.0 to 7.1 are considered as major upgrades hence destructive. Be prepared for ~30 minutes of outage + ~10 minutes for fabric recovery (with data traffic being forwarded).

  1. firmware download logical-chassis scp directory /home/brcdsup/nos/nos7.1.0b host user brcdsup password xxx rbridge-id all coldboot
