What does s0 0 mean in router configuration

0 0 1 indicates the slot number, the subcard number, the interface serial number, and the slot number

indicates the slot number of the board.

Subcard number: Daughter cards are generally not supported on each board of the router, so the unified value can be 0 interface sequence number:

Indicates the sequence number of each interface on the board.

Represents the position of an interface, such as the ports of the first board.

It represents the interface of the router, which has F port, S port, and G port.

Hello! This is due to the module number.

Turn off the device, right-click "Configu", click on the slot, click on "slot 0" under the adapter to add "nm-4t", and then start to have the s0 0 string slogan.

Hope you succeed, if added in slot 1 it will be s1 0. The ios I'm using is the iOS of the 3640 router

S0 0 is the abbreviation of serial port, which is the serial port external network interface. When operating on the console, you can use interfece s0 0 or int s0 0 to enter, and you need to enter the global configuration mode.

end exit.

The router interface is nothing more than a few Serial external network interfaces, Ethernet Ethernet interfaces, FasterEthernet fast Ethernet interfaces, AUX auxiliary interfaces, Consol console interfaces, BRI is ISDN interfaces, and many other logical interfaces are not described one by one! ~~

The explanation is as follows:

1: S stands for serial port, E stands for Ethernet card, Fa stands for Fast Ethernet port 2: According to your configuration information, it can be determined that it is a Cisco device, and the first slot number of the Cisco device is '0'

The first port on the slot is also numbered 0, so 0 1 represents the second port on the first slot.

3: Routes and routes can be directly connected with S port, or E port, there is no limitation.

4: When using the serial port connection, you should look at the serial port line, 2 heads indicate DTE and DCE respectively, the port of the device you DCE connects to configure the clock frequency, that is, in your command, clock rate, 5: The ports of the default route are closed, and no shutdown is required to activate it after the configuration is completed.

Routing. Simple setup!

s0 indicates that it is an interface. There are 4 interfaces in a general route.

This seems to be Cisco's routing!

I'm also a beginner. You can go to my group and chat: 40922226

s=serial port s0 0 means 0 slot 0 interface of the serial port.

shutdown indicates that the segment port is closed.

noshutdown indicates that a port is open.

Generally speaking, s0 0 represents the serial port of slot 0, and f0 0 represents the fast Ethernet port of slot 0.

S is the abbreviation of serial port.

f is an abbreviation for Fast Ethernet Interface.

S stands for Serial, which is the serial interface.

s0 0 0 refers to the 0th slot, the 0th serial port of the 0th module, there are some large Cisco routers with many plugs, 1 is called 1 slot, and there are similar:

F0 0 is the 0th Fast Ethernet interface of the 0th module of FastEthernet.

The default route is configured only when there is only one available path. IP Route is the configuration of static routing. The first group is the destination address and it is represented by wildcards, and the second group is the address mask used on this network.

When IP Routing on the router is invalid, use it to specify the default route, which is used to install iOS etc. in RxBoot mode (No IP Routing). Or disable IP routing to allow the router to be used as the host, in which case you need to configure the default gateway. In addition, this command is commonly used on Layer 2 switches because there are no Layer 3 routing entries on Layer 2 switches.

Both are used on routers with valid IP routing, and the difference is whether the routing protocol propagates this routing information. For example, IGRP is not recognized, so the default route must be propagated with ip default-network.

The meaning of this command is a default route, and the next hop is the exit s0 0 of the router itself, and the default route we generally use at the border of the network.

g0 0 where g is gigabitethernet and 0 0 is yes.

Interface 0 in slot 0.

s0 0 0 is represented as the 0th serial interface on module 0 in slot 0.

Serial interface, also known as "serial port", also known as serial communication interface (usually referred to as COM interface), is an extended interface that uses serial communication mode. Common examples include RS-232 for general PC applications (using 25-pin or 9-pin connectors) and half-duplex RS-485 and full-duplex RS-422 for industrial PC applications.

In layman's terms: one is a network cable interface, the other is a 9-pin interface, the length is different, the wire is different, the function is different, in short, the difference is very big.

s0 1 represents the second port of slot 0.

The number after in an IP address is the number of network bits.

The IP must be set for each port, and the command to enter the port is similar to int e0

This is the interface representation method of the enterprise router, and there are many interface representation methods in the enterprise router according to different configurations, which are described as follows:

Independent interface notation: type interface number, such as s0, e0, etc.;

There is a module interface notation: type module number interface number, as you said s0 1 is the synchronous serial interface 0 module 1 interface;

Interface notation with submodules: Type Module Number Submodule Number Interface number, e.g. s1 0 1 is the 1 interface of the synchronous interface module 1 module 0 submodule.

You won't learn it at Peking University Jade Bird, right? . . I also learned about routers.
