The BIG-IQ systems and data collection devices require bidirectional
communication with the BIG-IP devices in your network to successfully manage them. The
ports required must be open to allow for this required two-way communication. You might
have to contact a firewall or network administrator to verify that these ports are open,
or to have them opened if they are not.
The ports required for your BIG-IQ solution depend on a number of
factors such as the services running on the devices you manage, the BIG-IP version
running on those devices, and the number of subnets configured on your network.
