4.VLAN (MAC)
VMPS Management Policy Server (VLAN Management Policy Server, VMPS)
When a frame arrives at the dynamic port, the
switch
queries the VMPS according to the source address of the frame to obtain the corresponding VLAN assignment.

5. Multi-switch configuration VLAN
1. Set the connection ports of the two switches to trunk mode
1.>enable
2.#conf t
3.(config)#interface G 0/1
4.(config-if)#switchport mode trunk
//View show interface G0/1 switchport
2. Configure vlan on the two switches respectively
6.VTP
VTP (VLAN Trunking Protocol): is a VLAN trunking protocol, also known as a
virtual
local area network trunk protocol. It is a Cisco proprietary protocol. The function is that more than a dozen
switches
are in the
enterprise network, and
the
workload of configuring VLAN is heavy. You can use the VTP protocol to configure one switch as a VTP server, and the other switches are configured as VTP clients, so that they can automatically learn the VLAN information on the server.

8. Turn on the Layer 3 switch routing function
1. Configure vlan
