Cisco ASR 5000, Installation Manual

Counters and Bulkstats
The ASR 5000 maintains many counters for gathering statistics and troubleshooting. In general you should
not regularly clear the counters, just let them increment over time. Counters track events since the chassis
booted (unless cleared), unlike
show commands that give the current state (for example, the current number
of calls). See the on-line help for a list of choices. A partial list of counters to choose from are:
• show port datalink counters
• show port npu counters
•
show radius counters all
•
show l2tp full statistics
• show session disconnect reasons
• show session counters historical all (This is an excellent command to see the call volume history for
past three days.)
You may clear the counters via CLI clear commands.
A bulk statistics feature allows you to push a very large array of statistical data to a remote server. Bulkstats
provide detailed information about the chassis' condition, particularly over extended periods of time.
See Configuring Bulk Statistics section in the System Administration Guide for more information.
Summary of Maintenance Tasks
This section contains a quick reference for when to perform various maintenance operations on the ASR 5000
chassis. These operations include, but are not limited to:
• Load on the chassis
• The number of operators regularly accessing it
• The placement of the chassis within your network
• Available staff to perform maintenance tasks
• Support level agreements within your organization
• The specifics of your chassis configuration
• Your organization's experience with the types of issues, such as subscriber or network, that you encounter
over time
Constant Attention
• Watch SNMP traps for alarms/thresholds and take appropriate action. The traps inform you of serious
problems that can occur on the system, including those that do not involve the ASR 5000.
• If you have an Element Management System (EMS) server that relies on bulkstats and other data, pay
attention to alarms and call load.
