SEP Configuration
This chapter describes how to configure the Smart Ethernet Protection (SEP). SEP is a ring network protocol specially used for the Ethernet link layer. It blocks redundant links to prevent logical loops on a ring network.
- Introduction to SEP
- Principles
- Applications
- Configuration Task Summary
- Licensing Requirements and Limitations for SEP
- Configuring Basic SEP Functions
When there is no faulty link on a ring network running SEP, SEP can eliminate loops on the Ethernet. When a link fault occurs on the ring network, SEP can immediately restore the communication between the nodes on the network. - Specifying an Interface to Block
By default, the blocked interface is one of the two interfaces that complete neighbor negotiations last. Sometimes, the negotiated blocked interface, however, may not be the expected one. You can configure a blocked interface to suit your needs. - Configuring SEP Multi-Instance
- Configuring the Topology Change Notification Function
The topology change notification function is configured on the device that connects a lower-layer network to an upper-layer network. This function enables the device to notify the peer device of topology changes in the lower-layer and upper-layer networks. All the devices on the network where the peer device resides then delete original MAC addresses and ARP entries and learn new MAC addresses to ensure uninterrupted traffic forwarding. - Maintaining SEP
