The following considerations apply with DHCP option 43:
A dynamic IP address overwrites the default value (hac.extremecloudiq.com) or 0.0.0.0.
A static server IP address overwrites a dynamic server IP address.
A dynamic server IP address does not overwrite an existing static server IP address.
If a static server IP address is already configured and a new value is received from the DHCP server, the following warning displays on the console: WARNING Dynamic Cloud IQ Server Address x.x.x.x provided by DHCP option 43 could not be set. Static configured server address y.y.y.y cannot be overwritten by a dynamic address.
The default value (hac.extremecloudiq.com) replaces the dynamic server IP address if the DHCP Client is disabled on the switch.
The dynamic server IP address is not saved in the running-config.
