I have applied the virtual-controller-IP on my master IAP and configuration is persisted on my master IAP which can be viewed in the running configuration of the IAP.
WAP# configure terminal WAP (config) # virtual-controller-ip 200.20.200.237
WAP (config) # end
WAP# commit apply
committing configuration...
configuration committed.
WAP# reload all
Do you really want to reset the system (y/n): y
How to delete or disable this applied configuration using Aruba CLI?
To disable or unset a Virtual Controller IP we need to apply virtual-controller-ip as 0.0.0.0 in the master wap or Virtual controller.
Let's apply virtual-controller-ip as 0.0.0.0 in master WAP.
WAP# configure terminal
We now support CLI commit model, please type "commit apply" for configuration to take effect.
WAP (config) # virtual-controller-ip 0.0.0.0
WAP (config) # end
WAP# commit apply no-save
committing configuration...
Now in the master wap running-config we don't have virtual-controller-ip.
WAP# show running-config
virtual-controller-country US
From Aruba 8.3 MIB, it says when the Virtual controller IP address is not set, it will return 0.0.0.0.
