1. Background
Generally implement VLAN communication, or use a three-tier switch, or a single arm routing, both of which are very expensive, so when there is the need for VLAN communication, and the data volume of the VLAN communication is not very large, with 50 of Soho route to build a network is very affordable.
My original demand is this:With an n-port two-la
The introduction of vlan of a Huawei switch and three VMPS modes. In the explanation of vlan of a Huawei switch, there are three VMPS modes (but User Registration Tool, namely URT, only supports open mode ). How to configure dynamic vlan and VMPS of a CATALYST 4500 series switch? This article takes cisco ios 12.2 (31) SGA as an example.

In fact, the essence of a layer-3 switch is a layer-2 switch with the routing function. The routing mainly belongs to the network layer function in the OSI reference model, so the layer-3 Switch also has the routing kinetic energy. Now, we know that computers with different VLANs can communicate with each other as long as they can provide routes between VLANs. However, if a router is used for inter-VLAN routing, as the traffic between VLANs increases,
2618 switch VLAN configuration Switch A and switch B are connected through port 16. Port 1 of Switch A and Port 2 of Switch B are members of VLAN2, port 2 of vswitch A and port 4 of vswitch B are members of vlan3. 1.15 configuration steps vswitch A is configured as follows: zte (cfg) # set vlan 2 add port 16 tag // add port 16 to VLAN 2, and type tagzte (cfg) # s

VLAN (virtual LAN), translated into Chinese is a "virtualized local area network". The physically connected network is divided into a plurality of logical independent virtual subnets, originally, the second layer switch can only build a single broadcast domain, but with the VLAN function, it can divide the network into multiple broadcast domains.The switch allows the LAN to be divided into multiple VLANs, a

The main network technology we currently use when constructing an enterprise network is generally based on exchange and virtual networks. The exchange technology changes shared media to exclusive media, greatly improving the network speed. The Virtual Network Technology breaks the restrictions of the geographical environment. without changing the physical connection of the network, the wo

Preface
VLAN, as a virtual LAN technology, plays an important role in switch networking management and cloud computing platform network services, especially in the current Virtual Switching OVS, VLAN applications are more flexible and important. For the basic usage of

1. VLAN: Virtual LAN, is the logical combination of switch ports, VLAN work in the second layer of OSI, a VLAN is a broadcast domain, the communication between the VLAN is through the 3rd layer of routers to complete.

VLAN generation mainly to the design of local area network increased flexibility, so that network administrators in the division team, no longer limited by the user's physical location. VLANs can be implemented on one switch, or across switches. It can be divided according to the location, function or department of the network user.
VLAN features flexibility and scalability, and using
1. Networking requirements: 1. switchA and SwitchB use trunk for interconnection. Mutual access is allowed between PCs with the same VLAN. Mutual access is prohibited between PCs with different VLANs. PC1 and PC2 are located in different VLANs. You can set the IP address of VLAN Interface 10 of the SwitchB layer-3 Switch to 10.1.1.254/24, when the IP address of VLAN
Two vswitch configuration modes: Configure VLAN Based on port division as an example.
Vswitch configuration modes can be divided into two categories: one is the configuration mode represented by a CISCO switch, and the other is the configuration mode represented by a Huawei or H3C switch. In fact, the two configuration modes are not essentially different, but the command names and configuration methods are different. If you grasp the basic principles
Note: switchport mode trunk can run directly on the 2950 switch, which enables 802.1q directly. To enable the relay function on vswitches such as 3550 and 4500, you must first select the encapsulation method, that is, run switchport trunk encapsulation dot1q.Sw0 # vlan databaseSw0 (vlan) # vtp domain ContosoSw0 (vlan) # vtp password ContosoSw0 (
The VLAN mentioned here is a VLAN that complies with the IEEE 802.1Q standard.The frame structure is as follows:|da|sa|tag| type| date| crc|VLAN frames Add a 4byte long tag field to the source MAC address, relative to normal Ethernet frames. This field is specifically divided into:| tpid|priority| cfi| Vlan id|Tpid:tag
