Table 5-7 lists the VLAN configuration tasks.

Description |
Task |
|---|---|---|
Assigning a LAN to VLANs |
LANs can isolate the hosts that do not need to communicate with each other, which improves network security, reduces broadcast traffic, and prevents broadcast storms. |
|
Configuring Inter-VLAN Communication |
After VLANs are configured, users in the same VLAN can communication with each other while users in different VLANs cannot. To implement inter-VLAN communication, configure the VLANIF interfaces which are Layer 3 logical interfaces, Layer 3 sub-interface. |
|
Configuring VLAN Aggregation to Save IP Addresses |
VLAN aggregation saves IP addresses and implements inter-VLAN communication. |
|
Configuring a MUX VLAN to Separate Layer 2 Traffic |
Configuring a MUX VLAN allows users in different VLANs to communicate with each other, and separates users in a certain VLAN. |
|
Configuring an mVLAN to Implement Integrated Management |
Management VLAN (mVLAN) configuration allows users to use the VLANIF interface of the mVLAN to log in to the management switch to centrally manage devices. |
|
Configuring Transparent Transmission of Protocol Packets in a VLAN to Improve Forwarding Efficiency |
A switch directly transparently transmits protocol packets in a specified VLAN without sending them to the CPU. |

Configuring an Interface to Discard Incoming Tagged Packets |
If a user connects a switch to a user-side interface without permission, the user-side interface may receive tagged packets. To prevent unauthorized access, you can configure the user-side interface to discard incoming tagged packets. |
