Load Balancing Between Equipment

User session information of multiple NetEngine 8000 Fs is backed up on the NetEngine 8000 F. When a master device is faulty, user services are switched to the slave device.

As shown in Figure 1, the NetEngine 8000 F in the middle serves as the slave device, and the NetEngine 8000 Fs on both sides serve as the master devices. Under normal circumstances, users go online using the master devices. When master devices or the links of master devices are faulty, the slave device takes over user services.

In the topology shown in Figure 1, focus on the VLAN planning, and make sure that the two NetEngine 8000 Fs can be accessed by users simultaneously.
