Vro interfaces are very important for network connection and routing functions. Here we will give a comprehensive explanation of vro interfaces and connection knowledge. A vro has powerful network connection and routing functions. It can be physically connected to a variety of different networks, which makes the router interface technology very complex, the more high-end router interfaces there are, the more network types it can connect. Vro ports include LAN ports, WAN ports, and configuration

One more note is that the cascade between the hub devices is usually done through a cascading port, and that the interconnection between routers and hubs is done through a normal port. In addition, the router and hub dev
basically eliminated. However, if you want to use it for Cascade, its speed also has some advantages.
AUI port (Figure 3): It is a transceiver interface. It is used to connect a signal transceiver that is connected to a crude cable. It is a 10BASE-5 network standard. Like 10BASE-2, it is also in the past.

VroInLanThere are many types of LAN interfaces to match different routes, such as the AUI port and SC port. LAN interfaces are mainly used to connect routers and local area networks. Because there are also a variety of LAN types, this determines the LAN interface types of routers.
Different networks have different LAN interface types, common Ethernet interfaces include AUI, BNC and RJ-45 interfaces, as well
the coarse coaxial cable. It is a "D" Type 15-pin interface, this is one of the most common ports in the ring or bus network. The router can connect to the 10Base-5 network through a coarse coaxial cable transceiver. But more is the use of external transceiver AUI-to-RJ-45), to achieve the connection with the 10Base-T Ethernet. Of course, you can also use other
the 10BASE-5 network via a coarse coaxial cable transceiver, but more often with an external transceiver (AUI-TO-RJ-45), to connect to the 10BASE-T Ethernet network. Connections to fine coaxial (10base-2) or optical cables (10BASE-F) can also be implemented with the aid of other types of transceivers. The router AUI i

Vswitch interface type: AUI Interface
The AUI interface is used to connect to a coarse coaxial cable. In t
, in fact, the two kinds of RJ-45 port is completely the same as the port itself, however, the network circuit structure corresponding to the port is different, so it cannot be connected at will.2. the AUI port is the LAN interface used to connect to the coarse coaxial cable. It is a D-type 15-pin LAN interface, this is one of the most common ports in the ring or bus network. The router can connect to the 10Base-5 network through the coarse coaxial ca

the timing token protocol, supporting a variety of topologies, transmission media for optical fiber. Optical Fiber Distributed Data Interface (FDDI) is a set of protocols that are developed by the United States National Standardization Organization (ANSI) to send digital signals on optical cables. FDDI uses a dual-loop token, with a transmission rate of up to 100Mbps.
CCDI is a variant of FDDI, which uses twisted-pair copper cables as a transmission medium with a data transmission rate usual

The rj -- 45 unshielded twisted pair connector has eight pins. In the 10base-t standard, only four wires are used, that is, 1st pairs of twisted pair wires use 1st and 2nd pins, 2nd pairs of twisted pair wires use 3rd and 6th needles (3rd pairs and 4th pairs for backup ). For specific usage instructions, refer to the instructions provided by the manufacturer.

A passive hub usually has a 10Base-2 port and some RJ-45 interfaces. The 10Base-2 connector can be used to connect the trunk. Some hubs also have AUI ports that can be connec
