Ring Node Visibility

3DB 23063 ADAA - Rev 004 July 2007
Guidelines are provided to confirm correct ring network operation.
A pre-requisite is to confirm that all links on the ring are:
• Operating error-free
• Correctly configured for NMS networking
• Correctly configured for traffic circuits
During installation each link should be installed and configured using data
prepared at the ring planning stage. A master reference must be prepared, as
recommended in Planning a Ring Network on page A-4
Once all links in the ring have been installed and configured, correct ring
operation can confirmed using the following procedures, which are based on a
CT connection (Ethernet NMS cable connection) at one node on the ring.
Refer to:
• Ring Node Visibility on page A-21
• Integrity of Individual Ring Links on page A-22
• Integrity of the Ring and Ring Circuits on page A-22
• Confirming Ring Wrapping and Unwrapping on page A-23
Use CT to log on to all nodes in the ring. (You will need the IP address for each
node)
Maintain connection to all nodes.
Screens may be layered, and brought to the front by clicking, or two or more
screens may be set side-by-side for viewing. Where necessary, drag a corner of a
screen to resize.
• If all nodes are visible, it indicates:
• NMS IP addressing and routing is OK.
• A normal unwrapped ring, or a wrapped ring with only one link inoperative.
To confirm normal ring operation, check the System Summary screen for
each node.
• If some nodes are not visible:
