Table 14 - REP Fields
Field Description
REP Admin VLAN The administrative VLAN. The range is 2…4094. The default is VLAN 1.
REP ports are assigned to the same REP Admin VLAN. If the REP Admin VLAN changes, all REP ports are automatically assigned to
the new REP Admin VLAN.
Port Name The number of the switch port, including port type (such as Fa for Fast Ethernet and Gi for Gigabit Ethernet).
Mode The administrative mode. To set this mode, from the Configure menu, choose Port Settings.
Segment ID The ID of the segment. The segment ID range is from 1…1024. If no segment ID is set, REP is disabled.
Port Type Each REP segment must have exactly two primary edge ports and may have secondary ports to use when a primary port fails.
You can specify preferred primary and secondary ports. Configuring a port as preferred does not guarantee that it becomes the
alternate port but gives it a slight edge among equal contenders. You also can indicate that a port is connected to switches that
do not support REP.
Choose one of these port types:
• Edge—A secondary edge port that participates in VLAN load balancing.
• Edge no-neighbor—A secondary edge port that is connected to a non-REP switch.
• Edge no-neighbor preferred—A secondary edge port that is connected to a non-REP switch and is the preferred alternate
port for VLAN load balancing.
• Edge no-neighbor primary—A secondary edge port that always participates in VLAN load balancing in this REP segment and
is connected to a non-REP switch.
• Edge no-neighbor primary preferred—An edge port that always participates in VLAN load balancing in this REP segment, is
connected to a non-REP switch, and is the preferred port for VLAN load balancing.
• Edge preferred—A secondary edge port that is the preferred alternate port for VLAN load balancing.
• Edge primary—An edge port that always participates in VLAN load balancing in this REP segment.
• Edge primary preferred—An edge port that always participates in VLAN load balancing in this REP segment and is the
preferred port for VLAN load balancing.
• None—This port is not part of the REP segment. The default is None.
• Preferred—A secondary edge port that is the preferred alternate port for VLAN load balancing.
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 an STP network. The default is cleared 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.
