Layer-3 Ethernet switch: introduces L2 VLAN forwarding, configurations in layer-3 Ethernet switches, MAC addresses, and L2 VLAN forwarding, I hope you will have a clear understanding after reading the following articles. The forwarding mechanism of a layer-3 Ethernet switch is divided into two parts: layer-2 forwarding

In the composition of wireless networks, the use of many devices deserves a detailed understanding. Today we will talk about the failure of VLAN wireless Internet access switches. The following is an experience shared by a netizen: A strange problem occurs in the VLAN of the two departments where an office area is located. Some websites on the Internet can be accessed normally, but some websites cannot; ema

C-F6. Multi-VLAN configuration DHCP? C3750-E? CISCO switches, c-f6c3750-e C-F6. Multi-VLAN configuration DHCP? C3750-E? CISCO switches. After VLAN and interface are allocated according to our plan, we need to consider which VLANs need to be configured with the DHCP service.

During hard disk data sorting, we found the original dtp vlan jump experiment video, which includes DTP protocol data packets, test tools, videos, and lazy. The following are the steps. Download the video and watch it. It was very casual. At that time, I kept it for reference. Implementation of VLAN jump attacks I don't talk much about it. I only find such a term on the Internet. No one has told me the

In the wireless network composition, the use of a lot of equipment is worth a detailed understanding. So today we're going to talk about the problem of VLAN wireless internet switch failures. The following is a netizen's experience sharing: Unit one office area where the two departments VLAN appeared a very strange problem, some websites on the internet can be no

Vlan10 and vlan20 represent different departments in reality. 2. SW1 is a layer-3 switch, and SW2 is a layer-2 switch. 3. R5 simulates the

Router and three-layer switch experiment Demo--a gateway that acts as a two VLAN--Hundred dishes background : We know that routers have routing capabilities, so you know how to configure two gateways on a router interface (such as a two VLAN gateway)? Note that it is on one interface instead of two, and we sometimes use the three-layer

interconnected with layer-3 switches. When using a router to connect to a vrovlan, you generally need to set sub-interfaces corresponding to each VLAN on the LAN Interface, while a layer-3 Switch generates a "VLAN Interface" internally )". A VLAN interface is an interface used to send and receive data from each
