Syntax Description
Defaults
REP is disabled on the interface.
When REP is enabled on an interface, the default is for the port to be a regular segment port.

Command History
Usage Guidelines
REP ports must be Layer 2 trunk ports. A non-ES REP port can be either an IEEE 802.1Q trunk port or
an ISL trunk port.
REP ports should not be configured as one of these port types:
•
SPAN destination port
•
Private VLAN port
•
Tunnel port
segment-id
Assign a segment ID to the interface. The range is from 1 to 1024.
edge
(Optional) Identify the interface as one of the two REP edge ports. Entering the
edge
keyword without the
primary
keyword configures the port as the secondary edge
port.
no-neighbor
(Optional) Configure a segment edge with no external REP neighbor.
primary
(Optional) On an edge port, specify that the port is the primary edge port. A segment
has only one primary edge port. If you configure two ports in a segment as the
primary edge port, for example ports on different switches, the REP selects one of
them to serve as the segment primary edge port.
preferred
(Optional) Specify that the port is the preferred alternate port or the preferred port
for VLAN load balancing.
Note
Configuring a port as preferred does not guarantee that it becomes the
alternate port; it merely gives it a slight edge among equal contenders. The
alternate port is usually a previously failed port.
