Read ring status information. The answer is to be interpreted differently when asking a focal point or a member switch. Focal point (status of the whole FRNT topology): 1. ring mode: A focal point reports 'ring(1)' when the FRNT topology is intact. On a focal point this indicates OK. 2. bus mode: A focal point reports 'bus(2)' when it has detected an ERROR in the FRNT topology, i.e., the topology is broken. It can either be an error on any of its local FRNT ports (M or N), or elsewhere in the FRNT topology. Member switch (status of the member's local FRNT ports): 1. ring mode: A member switch reports 'ring(1)' when one or both of its FRNT ports are down or in blocking state. On a member switch this indicates an ERROR. 2. bus mode: A member switch reports 'bus(2)' when both its FRNT ports are in forwarding state. On a member switch this is an indication of OK, but it only has significance for this member switch, not the whole FRNT topology.
