3.6.1 HSIM-F6 FDDI Ring Statistics Screen Fields
The HSIM-F6 FDDI Ring Statistics screen allows the user to monitor the
current HSIM-F6 operational status.
The following list describes the Ring Statistics screen fields:
RING STATE
Displays the current ring state. The possible ring states are as follows:
• Ring-Op - The ring is functioning correctly.
• Isolated - The HSIM-F6 is not attached to the ring.
• Non-Op - The HSIM-F6 is attempting to enter the ring.
• Detect - The claim (beacon) process of the FDDI ring
protocol has exceeded one second. There may be a
problem.
• Non-Op-Dup - The ring failed to complete the claim (beacon)
process. This usually indicates a duplicate FDDI
address.
• Ring-Op-Dup - The ring is operational, but a duplicate FDDI
address may be present somewhere on the network.
• Directed - The claim (beacon) process did not complete
within ten seconds. The HSIM-F6 is sending
directed beacons to indicate a problem.
• Trace - A problem has been detected with the HSIM-F6 or
the nearest active upstream neighbor (NAUN). A
trace is being sent to notify the nearest active
upstream neighbor of the problem.
RING-OP COUNT
The Ring-Op Count keeps track of the number of times the FDDI ring has
initialized since the last time the HSIM-F6 (or host device in which it
resides) was reset. If this number grows steadily over a brief period of
time, it signifies the ring is unstable.
