Ring Status
2
This displays the status of the ring to which the STHI is currently
connected: if the STHI is bypassed, it refers only to the STHI hub’s internal
ring; otherwise, it refers to the stack’s common ring.
• Unknown — This reflects a transient state during which the
management agent is unable to determine the current ring status.
• Closed — The STHI has disconnected itself completely from other
hubs in the stack: it is not supporting the common ring and cannot
determine the ring state.
• Normal — The ring is operating trouble-free.
• Purge — The active monitor has issued a ring purge command to
clear all circulating transmissions. Communications will be restored
momentarily—when the active monitor releases a new token.
• Contention — The ring has entered into the active monitor
contention process to determine a new active monitor for the ring.
• Beaconing — The STHI has detected a beacon frame.
• Lobe Fail — A station failed the lobe self-test when attempting to
insert into the ring; soft-errors may have occurred.
Ring Number

This identifies the ring on which a bridge is available. Zero indicates that
there is no bridge on any ring in the stack.
Stations on a Ring

This displays the number of stations currently inserted into the ring. If the
STHI is bypassed, only the stations on the STHI’s self-supported ring are
counted.
Ports Enabled
