Huawei quidway s7700 - Checking the Configuration; Configuring SEP Multi-Instance; Establishing the Configuration Task

By default, the primary edge interface is not configured with the preemption mode, that is, the
non-preemption mode is adopted.
----End
10.3.4 Checking the Configuration
After specifying an interface to block, you can view information about a specified blocked
interface.
Prerequisite
The configurations of specifying an interface to block are complete.
Procedure
l Run the display sep topology [ segment segment-id ] [ verbose ] command to check the
topology status of a specified SEP segment.

10.4 Configuring SEP Multi-Instance
SEP multi-instance allows two SEP segments to be configured on a physical ring network. After
different protected instances are configured for the SEP segments and VLANs are mapped to
specified protected instances, load balancing and link backup can be implemented for service
traffic.
10.4.1 Establishing the Configuration Task
Before configuring SEP multi-instance, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the required data. This will help you complete
the configuration task quickly and efficiently.
Applicable Environment
in regular SEP networking, a physical ring network can be configured with only one SEP segment
in which only one interface can be blocked. If an interface in the SEP segment in the complete
state is blocked, all user data is transmitted only along the path where the primary edge interface
is located. The path where the secondary edge interface is located is idle, which leads to a waste
of bandwidth.
