Updating and deleting interfaces
Updating interfaces may affect dependent configurations, including interface zone binding, DNS, gateway, interface-based hosts, VLAN interfaces, and dynamic DNS.
Deleting an interface will also remove all dependent configurations including interface zone binding, DHCP server or relay, interface-based firewall rule, ARP (static and proxy), protected servers, protected server-based firewall rules, interface-based hosts and references from host groups as well as unicast and multicast routes.
Deleting a virtual interface will delete the firewall rule defined for it.
Your network connections may be temporarily nonresponsive or unavailable after updating or deleting interfaces.
