About device discovery

During the initial setup of your BIG-IQ system, you chose a specific master key passphrase. You must use this same passphrase during the initial setup later of other BIG-IQ or data collection device (DCD) systems that need to discover one another.
If the master key passphrases do not match, a BIG-IQ device cannot discover a remote DCD system, and the system generates an error message similar to this:
Discovery of BIG-IQ Data Collection Device 192.168.10.100 failed with state POST_FAILED and due to error Master Keys differ between this BIG-IQ and the one you are attempting to discover. Please configure both machines to have the same Master Key.
Before initiating any discovery process, make sure that the master keys on the two systems match. To view the master key for each system, simply open a console window on each system, log in, and at the system prompt, type the command
f5mku -K
