13.2.2 Smart RSTP (Ring-Only Mode) through the Command Line Interface (CLI)

A special case of a mesh structure is a ring. In many networks, network managers prefer to create a ring structure for redundancy and simplicity of the topology. In a ring structure:

1.All switches in the network are GE Multilin switches.

2.RSTP is enabled on all the switches.

3.The topology is a ring.

4.All switches in the ring have been configured to use the Smart RSTP (ring only mode) (as shown below).

5.All switches in the ring must use the same firmware revision.

The ring structure can demonstrate fast recovery times, typically faster than what RSTP can recover from a single fault. In many situations RSTP will recover in seconds, whereas smart RSTP (ring-only mode) will recover in milliseconds.

To configure Ring-Only mode, ensure the first three of the four situations described above are met.

RSTP mode has to be enabled before any configuration to the ring-only mode.

The RSTP command enters the RSTP configuration mode and enables/disables RSTP. By default, RSTP is disabled and has to be manually activated.
