Configuring Monitor Link of the CX111

Monitor Link monitors the uplink interface status and changes the downlink interface status when the uplink interface status changes. The uplink interface and downlink interfaces form a Monitor Link group.
When a device connects to an upstream device through a single uplink, services are interrupted if a single point failure occurs. In dual-homing networking, a downstream device is connected to two upstream devices to reduce impact of single point failures and improve network reliability.

Configure Monitor Link of the CX111 by following the instructions provided in the configuration guide:
