ZESS Overview

ZESS is ZTE Ethernet Smart Switch technology. It is efficient link
switch mechanism. When fault occurs, main link can switch to
standby link automatically and quickly to ensure service data nor-
mal transmission.
Function description is as follows: As shown in Figure 22, node 1
supports ZESS function, of which port 1 is primary port and port 2
is secondary port. When node 1 detects that both primary port and
secondary port are up, blocks protection service VLAN forwarding
function of secondary port. When node 1 detects that primary port
is DOWN, blocks that of primary port and open that of secondary
port. When node 1 detects that primary port recovers as UP, in in-
version mode, open primary port and block secondary port again,
whereas in non-inversion mode, keep primary port as blocked and
secondary port as open. In addition, when ZESS is switching, FDB
of block port need to be updated.
