H3C s5024p Switch Interconnect experiment

The first Tuesday Network management Experiment Report

Switch Interconnection experiment

Test Wiring diagram:

Switch Panorama:

Switches can be configured via HyperTerminal and Telnet

Control cable connected switch console port and computer host (can only transfer commands can not communicate, to communicate must connect the host and the switch through the network cable)

Connect other computers with a network cable, including switches and hosts (only the network cable can ping through)

The top and bottom two rows are the network cable socket, can see the light

Configuration Switch2 switch1 is the same.

a gateway is essentially a network that leads to other networksIPaddress . Like a network .Aand NetworkB, the networkAof theIPaddress range is"192.168.1.1~192. 168.1.254 ", the subnet mask is255.255.255.0; networkBof theIPaddress range is"192.168.2.1~192.168.2.254", the subnet mask is255.255.255.0. In the absence of a router , the two networks cannot beTCP/IPcommunication, even if two networks are connected on the same switch (or hub ),TCP/IPThe protocol will also be based on the subnet mask (255.255.255.0) to determine that the hosts in the two networks are in different networks. To achieve communication between the two networks, you must pass through the gateway. If the networkAthe host in the Discovery Packet is not on the local network and forwards the packet to its own gateway, which is then forwarded to the network by the Gateway .Bthe gateway, networkBthe gateway is forwarded to the networkB(as shown in the attached drawings). NetworkAto the networkBthe process of forwarding a packet. in today's many local area network adoption is the road Origin access network, so usually refers to the gateway is the router's IP address, the router must be in the same network segment as the host, observing whether the network number is the same through the subnet mask and IP address

IPaddress is a +Binary number of bits, usually divided into4a"8bits binary number"(i.e.4bytes). IPaddresses are usually used" dotted decimal notation (a.b.c.d) in the form of which,a,b,c,d are 0 A decimal integer between ~255.

The subnet mask cannot exist alone, it must be combinedIPaddress together with the addresses. The subnet mask has only one function, which is to put aIPThe address is divided into two parts: network address and host address . ForAclass address, the default subnet mask is255.0.0.0; forBThe default subnet mask for class addresses is255.255.0.0; forCThe default subnet mask for class addresses is255.255.255.0.

the length of the subnet mask is also +bit, the left is the network bit , with binary digits"1"said,1is equal to the length of the network bit, the right is the host bit, the binary number"0"said,0number equals the length of the host bit. The purpose of this is to allow the mask to be IP address to do bitwise AND operation with 0 to cover the original host number, without changing the original network segment number, and easily through 0 The number of digits in the subnet determines how many hosts

Like 192.168.0.1 and 192.168.0.2.
1. Subnet mask is 255.255.255.0
So 192.168.0.X in the same network segment, can access each other.
2. Hope the Mask is 255.255.0.0
So 192.168.x.x in the same network segment, can access each other.]

?

The subnet mask tells us which ones are the network address and the host address?

????? For example, IP address 192.168.1.25??? Subnet mask 255.255.255.0?

So the network address is 192.168.1.0?? The host address is??????

? for example?;? IP address 192.168.1.25???? Subnet mask 255.255.0.0?

So the network address is 192.168.0.0?? The host address is 1.25? The rest of the part is the host address.

Computers in the same network segment can communicate directly, but different network segments cannot communicate? For example, 255.255.255.0???? And 255.255.0.0? Is it possible to communicate directly? So there's a concept called the default gateway? He is a bridge between different network segments, with a default gateway to communicate across the network segment.
