ZESS

ZESS (ZTE Ethernet Smart Switch) describes a cost-effective link switchover mechanism.
It enables the services to be switched over to backup link rapidly when the active link
breaks down, so that normal service transmission can be guaranteed.
As the following figure shows, node 1 supports ZESS service. Port 1 is the master port
and port 2 is the standby port. When node 1 inspects that both the master and standby
ports are in UP mode, it will disable the service VLAN protection forwarding service of the
standby port; when node 1 finds the master port is Down, it will block VLAN forwarding
service of the master port, and enable VLAN forwarding service of the standby port;
when node 1 inspects that the master port resumes to UP mode, the inverted and
uninverted modes can be chosen. In inverted mode, the master port is opened and the
standby port is blocked again. In uninverted mode, the master port keeps blocked mode,
and the standby port is open. In addition, when ZESS takes action, FDB of the blocked
port should be updated.
