responder port
A redundant repeater port that connects to either a master primary or a secondary
port. Because responder ports are always enabled, no action is taken to switch ports
in case of link failure. However, a responder port does detect and report link failures
to its partner (master primary or master secondary) port by continuously pulsing its
fiber transmit LED on and off. If the master port connected to the responder port is
active, the responder port treats this event as a link failure and causes a link failover.
Link failures include the following conditions:
• Autopartitioning
• Management disable
• Carrier loss

cols.
ring
Connection of two or more stations in a circular logical topology. Information is
passed sequentially between active stations, where each one, in turn, examines or
copies the data, and returns it to the originating station, which removes the data from
the network. FDDI is a ring topology.
secondary port
A redundant master repeater port that is placed in the standby state when redundant
ports are configured.
Serial Line Internet Protocol
Used for transmitting Internet Protocol (IP) packets across serial lines.
server
A network node or specialized device that provides and manages access to shared
network resources, such as hard disks, printers, and software.
service node
A node to which a terminal is able to establish a session through an access server
port.
