1. MUX VLAN
1. Introduction to MUX VLAN
MUX VLAN provides a mechanism for network resource control through VLAN.
MUX VLAN is divided into Principal VLAN and Subordinate VLAN, and Subordinate VLAN is divided into Separate VLAN and Group VLAN.
- Principal VLAN can communicate with all VLANs in MUX VLAN
- Separate VLAN can only communicate with Principal VLAN, and is completely isolated from other types of VLAN, and the inside of Separate VLAN is also completely isolated
- Group VLAN can communicate with Principal VLAN, users in the same Group VLAN can also communicate with each other, but cannot communicate with other Group VLAN or Separate VLAN
2. Basic configuration
1. Create Principal VLAN and associate Group VLAN with Separate VLAN
vlan 10
mux-vlan
subordinate separate 30
subordinate group 20
2. Add interface to VLAN
port mux-vlan enable
3. View MUX VLAN
display mux-vlan
Two, port isolation
1. Introduction to port isolation
Port isolation realizes isolation between ports in the same VLAN. Users in the same port isolation group cannot perform Layer 2 communication, users in different port isolation groups can communicate, and users without port isolation can also communicate normally with users in the port isolation group.
Port isolation is divided into two modes: Layer 2 isolation and Layer 3 intercommunication and Layer 2 isolation and Layer 3 isolation. The default is Layer 2 isolation and Layer 3 intercommunication mode.
2. Basic configuration
1. Configure port isolation mode
port-isolate mode [l2| all]
2. Configure port isolation group
port-isolate enable group 1
3. View port isolation group
display port-isolate group all
