About the configuration of switches and hubs

with crossed lines. Hubs and switches do not need to be configured. After the connection is made, the host can set the IP address of the same network segment to access the same network at the same time.

Don't use the trunk. The trunk is used to transmit encapsulated data. Unless none of your 3 computers are on the same network segment or are assigned to different VLANs

It is necessary to connect another route to the switch, set up a single-arm route, and the line connecting the switch to the route must be set to the trun** road. You just need a direct connection in your current situation. Note that the host IP address is OK on the same CIDR block as 1

1.The hub and switch are connected with a crossover wire.

2.If you are going to add 3 computers to the LAN and need to add them to a certain VLAN, you can connect the port that has been assigned to a VLAN on the switch to connect to the hub, and then configure the IP and subnet mask on the 3 computers to ensure that they are in the same network segment as the computers in the same VLAN.

Of course, with a crossed line, it's good to connect it. Draw the ports of the hub on the switch to a VLAN, and set the IP of the three computers to the network where the VLAN is located. The trunk protocol is used to support the same VLAN communication between different switches.

1.What cables are used for hubs and switches? Straight-through line.

2.What other configurations do I need for switches and hubs? No, the port of the switch does not need to be changed to trunk.

No configuration is required.

The hub and the book do not support relays, so you don't need to set up a direct connection to connect it.

Straight-through cable for hubs and switches. Don't do anything configuring.

If you talk too much, you won't understand it all at once.

To put it simply: a hub is like a thread divided into multiple threads.

Switch = hub + LAN connection function (the computer on the same switch can play games online, even if there is no Internet access).

Router = switch + server function (the router is equivalent to a computer, and he can connect to the computer above him after connecting to the Internet).

1. Essential differences:

The switch can divide the conflict domain The hub cannot divide the conflict domain This is the most essential difference between them The hub is connected to n computers, they share a zone, and if there is a conflict in this zone, all computers are affected. The switch is connected to n computers, and each switch port is an independent area, even if there is a conflict, the conflict is limited to the corresponding switch port and does not affect other computers.

2. Differences in resource occupation:

For example, a 100M switch has a speed of 100M for each computer connected to the switch, and the hub divides 100M resources. Moreover, the hub communicates through broadcasting, which occupies a lot of network resources.

3. Differences in types:

The hub is a broadcast packet, the switch is an isolated packet, and the hub is more than the switch card, because several computers connect to the hub to access the Internet as if they are queuing up to go to the Internet, and one goes up first and then the next switch is free to access the Internet, without queuing.
