Ethernet Automatic Protection Switching
Figure 21: Gigabit Ethernet fiber EAPS MAN ring
One port of the master node is designated the master node’s primary port (P) to the ring; another port is
designated as the master node’s secondary port (S) to the ring. In normal operation, the master node
blocks the secondary port for all non-control traffic belonging to this EAPS domain, thereby avoiding a
loop in the ring, like STP. Layer 2 switching and learning mechanisms operate per existing standards on
this ring.
NOTE
Like the master node, each transit node is also configured with a primary port and a secondary port on
the ring, but the primary/secondary port distinction is ignored as long as the node is configured as a
transit node.
