the interval, in seconds, between station port retries. You should select a
value which is a multiple of 7; values which are not divisible by 7 will be
rounded down to the nearest appropriate value.
Each value is set as soon as the mouse button is released; footer messages will
indicate set failure.
Using the Find Options
The Ring Map window provides several search options that allow you to discover
individual stations on the selected ring network by any one of the following
characteristics:
• Drop
• Board and Port Index
• Station Name
• MAC Address
For convenience, you can also identify the following stations of interest:
• Active Monitor on the ring
• The Ring Management Station
• Last Beaconing Station on the ring
And you can identify a selected station’s:
• NAUN (Nearest Active Upstream Neighbor)
• NADN (Nearest Active Downstream Neighbor)
Finally, to keep track of station performance, you can identify stations on your
network in ascending (By Lowest –> Highest) or descending (By Highest –>
Lowest) order of frames processed, total errors, or specific errors.
NOTE
Remember, not all devices nor all versions of device firmware support the ability to
configure station port retry parameters; if the device you are monitoring does not support
this feature, the related fields will be grayed out. Where these parameters are not settable,
station ports will be retried once, at a pre-determined interval, then remain disabled until
further management action is taken.
