Configure Card Statistics—AXSM-E, AXSM-32-T1E1-E, AXSM-XG
Configures the TFTP bucket statistics. This command allows the user to change the statistics
configuration for the card. Part of the configuration controls the bucket interval and the collection
interval. These parameters are used to control the generation of files (that contain statistics) that are
transferred to the Cisco WAN Manager (CWM) using the FTP protocol.
The card statistics level (stats level) cannot be set if there is any configuration on the lines, such as
logical ports. You must set the stats level before you can add any logical ports. However, you can set the
bucket interval and the collection interval after you have added logical ports.
Statistical alarms are different than integrated alarms. An integrated alarm indicates a persistent traffic
loss at either the local end, such as the LOS and LOF alarms, or at the remote end, such as the RDI alarm.
A statistical alarm indicates that a statistical counter has exceeded the threshold for alarm indication. For
instance, the Severely Errored Seconds (SES) counter might exceed the corresponding 15-minute
threshold. For this condition, a statistical alarm is raised, which indicates a degraded performance that
is not due to persistent traffic loss.
Statistical alarms are based on fixed statistics collection intervals. There are two types of fixed statistics
collection intervals:
• 15-minute
• 24-hour
The start of an interval is aligned to the time of day. For instance, 11:15, 11:30, 11:45, and so on. At the
end of the interval, the corresponding statistical alarms are cleared. An alarm is raised again if a counter
exceeds the threshold during the new interval.
Types of Card Statistics
The types of card statistics that are reported, and at which levels, are shown in the following tables.
