Chapter 3 Manage the Switch via the Device Manager Web Interface
Port Type The REP port type of the port can be: Primary, Edge, Transit, No-neighbor Primary, No-neighbor, and None.
The default is None. Following are Port Type definitions:
• Primary: This port is a primary edge port. This port always participates in VLAN load balancing in the REP
segment.
• Edge: This port is a secondary edge port. It also participates in VLAN load balancing in the REP segment.
• Transit: This port is a non-edge port in the REP segment.
• No-Neighbor Primary: This port is a primary edge port connected a non-REP switch.
• No-Neighbor: This port is a secondary edge port connected to a non-REP switch.
• The no-neighbor edge ports contain all properties of regular edge ports. These ports allow construction
of a REP ring containing a switch that does not support REP protocol.
• None: This port is not part of the REP segment.
You must configure two edge ports on each REP segment, a primary edge port and a port to act as a
secondary edge port. REP ports follow these rules:
• If only one port on a switch is configured in a segment, the port should be an edge port.
• If two ports on a switch belong to the same segment, both ports must be edge ports, or both ports must
be regular segment ports.
• If two ports on a switch belong to the same segment and one is configured as an edge port and one as a
regular segment port (a misconfiguration), the edge port is treated as a regular segment port.
STCN Interface Configure segment topology change notices (STCNs) for a port. The default is None.
TCNs are used within the segment to notify REP neighbors of topology changes. At the edge of the
segment, REP can propagate the notification to the STP or to the other REP segments.
STCN Segment Configure STCNs to a segment ID. The default is a blank field.
TCNs are used within the segment to notify REP neighbors of topology changes. At the edge of the
segment, REP can propagate the notification to the STP or to the other REP segments.
STCN STP Configure STCNs to a STP network. The default is an unchecked checkbox.
TCNs are used within the segment to notify REP neighbors of topology changes. At the edge of the
segment, REP can propagate the notification to the STP or to the other REP segments.
