BIGIQ/DCD and BIGIP Admin password change
Hello, I need to change the Admin and Root passwords of my F5 environment.
The topology is:
BIGIQ-CM with HA
and BIGIP devices in the cluster.
I saw I can change automatically for all managed BIGIP devices in bulk from BIGIQ.
A few questions about:
1. When I change the BIGIP devices. Will I lose the connectivity from BIGIQ? ELA license? Management?
If yes, how should I deal with it, without having to add everything again?
2. The same thing happens if I change the password of BIGIQ, do I need to reconfigure the HA between the active and standby?
3. Changing the password on the DCDs - I will lose the cluster and data. And would you like to add them again?
This is the same case as for Big-IP, the password is used only once time to exchange SSL certificates, After this password exchange, all communication uses these certificates for authentication and communication.
To be more clear, when you establish communication with another device, the peer device doesn´t save the password of the other system, it saves the SSL certificate to establish the communication,
Hope it works.
