Overview of WushanFS

USG6000 interface overview Interface types An NGFW supports physical and logical interfaces. 1. Physical interface a. Layer 3 Ethernet interface. Description: Works at the network layer to process Layer 3 packets with an IPv4 or IPv6 address specified and supports routing functions. b. Layer 2 Ethernet interface. Description: Works at the data link layer and processes Layer 2 packets, implementing rapid Layer 2 forwarding. 2. Logical interface a. Virtual template (VT) interface. Description: Helps a Point-to-Point Protocol over Ethernet (PPPoE) server with PPP negotiation or encapsulates Layer 2 Tunneling Protocol (L2TP) packets. b. Dialer interface. Description: Used by a PPPoE client. c. Tunnel interface. Description: Applies to packet encapsulation and decapsulation and IPv6 transition technologies. GRE and IPSec are common encapsulation protocols. d. Null interface. Description: Any packets transmitted over this interface are discarded. It is mainly used for route filtering. The null interface cannot be configured through the web UI. e. VLAN interface. Description: A Layer 3 logical interface that is assigned an IPv4 or IPv6 address. VLAN interfaces transmit packets between VLANs. f. Layer 3 Ethernet subinterface. Description: Layer 3 Ethernet subinterfaces are Layer 3 logical interfaces created on a physical interface. f. Layer 2 Ethernet subinterface. Description: Layer 2 Ethernet subinterfaces are Layer 2 logical interfaces created on a physical interface. h. Eth-Trunk interface (interface aggregation). Description: A logical interface that consists of multiple Layer 2 or Layer 3 Ethernet interfaces. An Eth-Trunk interface provides high bandwidth and reliability. i. Loopback interface. Description: Remains in the Up state and is assigned a 32-bit subnet mask.

Introduction to S1720: The S1720 series switches are next-generation energy-saving gigabit Layer 2 Ethernet switches that support configuration of up to eight VLANIF interfaces. The series switches are equipped with console ports and can be managed and maintained using SNMP, command line interface (CLI), web-based network management system, Telnet, or Secure Shell (SSH) V2.0.
