A ring is a special case mesh structure. In many networks, network managers prefer to
create a ring structure for topological redundancy and simplicity. In a ring structure special
case:
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 ring-only mode (as
shown below).
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.
To enable ring-only mode, first
