• If the link was consecutively errored for more than 1% of the time, an alarm will be generated.
• If the link had more than 5 degraded minutes, an alarm will be generated.

Link metrics represents parameters measured during the operation/non-operation of the radio link
that provide a quantitative measure of how well the radio link is performing over time. All link
metrics are measured in terms of Codewords. A Codeword is a unit of data transmission over the
radio link. It contains information such as user’s data, error correction, and collation information so
that successive Codewords may be reconstructed at the receiving end into the user’s data.
There are two classes of link metrics:
1 Metrics that quantify how the link performed since the system was powered on:
show interface radio <slot/port> linkMetrics
(provides information since power on)
show interface radio <slot/port> 24HrMetrics
(provides information for the past 24 hours)
2 Metrics that quantify how the link performed when the two ends of the link were synchronized:
show interface radio <slot/port> radio 1HrMetrics [delta] [numVals]
(provides details for the last 24 hours)
show interface radio <slot/port> radio 1MinMetrics [delta] [numVals]
(provides details for the last 60 minutes)
show interface radio <slot/port> radio 1SecMetrics [delta] [numVals]
(provides details for the last 60 seconds)
show interface radio <slot/port> radio 1TickMetrics [delta] [numVals]
(provides details for the last N hardware ticks)
Three categories of metrics are maintained by the radio link’s software and hardware:
1 Cumulative metrics where only one set is maintained for the entire collection period.
LinkMetrics and 24HrMetrics are in this category.
2 Cumulative metrics where a table of values is maintained, providing metrics relating to the time
period when the two ends of the link are synchronized. 1HrMetrics and 1MinMetrics are in this
category.
3 Cumulative metrics where a table of values is maintained, providing metrics maintained by the
hardware which is used to derive the information in categories 1 and 2. 1SecMetrics and
1TickMetrics are in this category.
