port (775)
port
This command sets the port type attached to the ring as primary or
secondary. Each node must connect to the ring through two ports as part
of the protection switching scheme – one port as the primary port and
another as the secondary port. Use the no form to remove a primary or
secondary port from the ring.

port { primary | secondary } port-number
no port { primary | secondary }
primary - This port is open on the Protected VLAN and is used for
passing both control messages and data traffic. The master node
sends control messages from this port.
secondary - This port is blocked on the Protected VLAN and is used
only to receive control messages on the master node.
port-number - Range: 1-28

SAGE
If the ring is complete, the master node prevents a loop by logically
blocking all data traffic in the transmit and receive directions on its
secondary port. If the master node subsequently detects a break in the
ring, it unblocks its secondary port and allows data traffic to be
transmitted and received through it.
The primary port and secondary port must be removed from an EAPS
domain with the no port command, before specifying a new primary or
secondary port.
