The Ring Statistics Screen
3.6.1HSIM-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.
