• Unknown, Indicates the state of the ring cannot be
detected by the management station.
• Closed, Indicates that the management station is not
inserted into the ring and therefore cannot determine the
ring state.
• Normal, Indicates the ring is running with no problems,
and tokens are being detected by the management
station.
• Purge, Indicates that the active monitor has issued a
ring purge command. Communications will be restored
when a new token is released.
• Contention, Indicates that the ring has entered into the
active monitor contention process to determine a new
active monitor for the ring.
• Beaconing, Indicates that the management station has
detected a beacon frame.
• Lobe Fail, Indicates that a station failed the lobe self-
test when it attempted to insert into the ring.
Ring Number
Displays the number of rings on the network.
Stations on a Ring
Displays the number of stations inserted into the ring.
Ports Enabled
Displays the number of network lobe ports enabled.
Ring Speed
Displays the ring speed of the TRXI as either 4 Mb/s or 16 Mb/s.
NON-ISOLATING ERRORS
Non-Isolating Errors are “soft error” conditions that could have been
caused by any station on the ring. Their fault domain cannot be
detected.
Lost Frame Errors
Displays the total number of Lost Frame Errors. These errors
occur when the adapter fails to receive the end of the frame it
has just transmitted. The frame was lost somewhere on the ring
but there is no way to pinpoint where. This can be caused by
stations entering or leaving the ring.
