How much is the VLAN ID set, and how can the VLAN ID be obtained。。。。。。

Switches can generally divide 255 VLANs, and the ID of each VLAN can be any number between 1 and 4096. The ID is used to distinguish between different VLANs, and the tag untag member attribute can be set to label the downstream or upstream datagrams of the port.

The vlan ID is in the virtual machine.

is assigned on the property page, which may be a VLAN ID method that many administrators are familiar with. Of course, you can also use PowerShell scripts to assign VLAN IDs to VMs. This script is very useful if you want to assign VLAN IDs to multiple VMs.

VLAN IDs are a universal approach that most IT organizations use to isolate physical and virtualized workloads. However, by introducing VSID, cloud hosts.

Hosters can now connect 16 million virtual networks and provide virtual machine isolation for different customers.

I found the following on the Internet: The VLAN ID identifies the number of the VLAN to which the packet belongs, with a length of 12 bits and a value range of 0 4095. Since 0 and 4095 are reserved for the protocol, the value range of the vlan ID is 1 4094, but in my textbook it is:

VLAN ID: 4096, 1--1005 is the standard range, and 1025--4096 is the extended range. I hope it helps you, you can choose for yourself

VLAN ID Range Range Purpose Remarks.

0,4095 reserved System use only Users can't view and use these VLANs

1 Normal Cisco default VLAN Users are able to use the VLAN, but cannot delete it.

2-1001 OK VLANs for Ethernet Users can create, use, and delete these VLANs

1002-1005 OK Cisco default VLANs for FDDI and Token Ring Users cannot delete these VLANs

1006-1024 Reserved System use only Users cannot view and use these VLANs

The 1025-4094 extension is only available for Ethernet VLANs

As long as it's not"1" line because 1 is there by default.

VLAN ID means the ID number of the virtual machine LAN. PVID is the port vid of the port.

And the difference between Liang Jing is as follows:

1. Only one of the common access port PVID and VID is the same;

2. If it is a hybrid or trunk port, because the port can recognize multiple VLANs, and the PVID can also be modified by itself;

3. A port can belong to multiple VLANs, but there can only be one PVID, and when receiving a packet without a tag header, it will be marked with the VLAN number represented by PVID, which is treated as a packet of the VLAN.

The Chinese name of VLAN (Virtual Local Area Network) is"Virtual LAN"。

A virtual LAN is a logical set of devices and users that are not limited by physical location, and can be organized according to factors such as function, department, and application, and communicate with each other as if they were in the same network segment.

PVID is the port-base VLAN ID, that is, the virtual LAN ID number of the port, which is related to the VLAN tag tag when the port sends and receives data frames.

It's already clear that Ah, start running and enter cmd enter.

Enter telnet, and then it will prompt Enter When you enter root, it will not show that root is hidden, you just need to enter press enter, and then enter the password, which is also hidden, and press enter after entering.

The command get port config portid 1 is not necessarily, because different routers are different, Cisco, provided that you enter global mode.
