(Only for Layer 3 Router) interface ethernet 1/1/47 (You choose the interface, Possibly the management Interface) ip address 192.168.X.5 255.255.255.0 write memory
(For Layer 2 Switch) ip address 192.168.X.5 255.255.255.0 ip default-gateway 192.168.X.1 write memory
To gain access to the web interface crypto-ssl certificate generate username [ username ] password [ password ] aaa authentication login default local aaa authentication web-server default local write memory
These are good. It is a lot easier to configure via the CLI though to be honest.
On the Layer-3 firmware, most IPs will go on the VE's or a loopback for routing protocols. The VEs are the VRIs (Virtual Router Interfaces), and are referred to as SVIs(Software Virtual Interfaces) on Cisco.
i.e. int ve 123 on the Ruckus vs int vlan 123 on a Cisco.
Other than that, you have untagged interfaces under a VLAN to assign access ports. If you use the TAGGED keyword under vlan and add interfaces, they are 802.1q trunk ports (i.e. same as dot1q on Cisco). If you have both, the vlan an interface is untagged within serves as its native vlan, which used to be referred to as dual-mode if you see older documentation.
