Class topic

Post 1. Principles of SEP

The SEP protocol is a dedicated link layer protocol for use on Ethernet ring networks. A SEP segment is the basic unit of the protocol. Only two interfaces on a Layer 2 switching device can be added to the same SEP segment...More


Post 2. SEP Topology Change Notification

SEP topology changes are classified into topology changes caused by interface faults and topology changes caused by fault rectification. The preemption function takes effect when the topology change is caused by fault rectification...More


Post 3. SEP, Specifying an Interface to Block

In general, a blocked interface is one of the last two interfaces that complete neighbor negotiation. In some cases, however, the negotiated blocked interface may not be the one a user expects to be blocked. A user can specify an interface to block as needed...More


Post 4. Suppression of SEP TC Notification Packets

We saw in SEP topology change notification, saw how the SEP protocol implements the SEP topology change notification, let's see now how to suppress it...More


Post 5. SEP Multi-Instance

In regular SEP networking, a physical ring network can be configured with only one SEP segment in which only one interface can be blocked...More
