Application Environment

Application Environment

This section describes the applicable environment of the VLAN.

VLAN Assignment

Port-Based VLAN Assignment
Figure 5-52 Networking diagram of port-based VLAN assignment

According to different requirements for interfaces, the switch in a data center assigns interfaces connected to users to different VLANs so that services of users are isolated. Each user has a virtual switch and each VLAN Is a virtual work group.

MAC Address-Based VLAN Assignment
Figure 5-53 Networking diagram of MAC address-based VLAN assignment

As shown in Figure 5-53, User A is initially connected to Switch A in a data center. Now, it is required that User A be connected to the another interface of SwicthA. To ensure that User A can still communicate with User C, configure the assignment of VLANs based on MAC addresses on Switch A. As long as the MAC address of User A remains unchanged, no configuration needs to be changed for User A to communicate with User C.

Inter-VLAN Communication

The inter-VLAN communication can be classified into two types, as shown as follows:

Multiple VLANs belong to the same device
Figure 5-54 Networking diagram of communications between multiple VLANs on the same device

As shown in Figure 5-54, if VLAN 2, VLAN 3, and VLAN 4 only belong to SwitchA, these VLANs are not VLANs across different switches. In such a situation, you can configure a VLANIF interface for each VLAN on SwitchA to implement the communications between these VLANs.

Multiple VLANs belongs to different devices
Figure 5-55 Networking diagram of communications between multiple VLANs on different devices

As shown in Figure 5-55, VLAN 2, VLAN 3, and VLAN 4 are VLANs across different switches. In such a situation, you can configure a VLANIF interface respectively on Switch A and Switch B for each VLAN, and then configure the static route or run a routing protocol between Switch A and Switch B.

VLAN Aggregation

Figure 5-56 Networking diagram of VLAN aggregation application

As shown in Figure 5-56, four VLANs, namely, VLAN 21, VLAN 22, VLAN 31, and VLAN 32, are configured. If these VLANs need to communicate with each other, you should configure an IP address for each VLAN on the Switch.

As an alternative, you can enable VLAN aggregation to aggregate VLAN 21 and VLAN 22 into super VLAN 2, and VLAN 31 and VLAN 32 into super VLAN 3. In this manner, you can save IP addresses by only assigning IP addresses to the super VLANs.

After Proxy ARP is configured on Switch, the sub-VLANs in each super VLAN can communicate with each other.
