The system view is displayed.
Step 2 Run:
sep segment segment-id
A SEP segment is created and the view of the SEP segment is displayed.
Step 3 Run:
protected-instance { all | { instance-id1 [ to instance-id2 ] &<1-10> } }
A protected instance is created in a SEP segment.
By default, no protected instance is configured in a SEP segment.

10.2.5 Adding a Layer 2 Interface to a SEP Segment and Configuring
a Role for the Interface
To ensure the normal forwarding of SEP packets in a SEP segment, add Layer 2 interfaces to
the SEP segment and configure different roles for the interfaces.
Context
After an interface is added to SEP segment, the interface sets its interface role to the primary
edge interface if the interface has the right to participate in the election of the primary edge
interface. Then, the interface periodically sends a primary edge interface-election packet without
waiting for the success of neighbor negotiation.
The primary edge interface-election packet contains the role of the interface (primary edge
interface, secondary edge interface, or common interface), the bridge MAC address of the
interface, interface ID, and the status of the topology database.
Table 10-8 lists interface roles.

Sub-role Description Deployment
Scenario
Common port - In a SEP segment, all interfaces except
edge interfaces and the blocked interface
are common interfaces.
A common interface monitors the status
of its directly connected SEP link and
notifies its neighboring interface of link
status changes in time. The neighboring
interface constantly floods the
notification message to other interfaces
in the SEP segment until the message
reaches the primary edge interface. The
primary edge interface then processes
the message.
