IPM FAQs
• How much of the router’s memory do collectors in SA Agent consume?
• How frequently can network performance measurements be taken?
• When IPM collects the data from the SA Agent using SNMP, is this data averaged or summarized
in any way?
• What data collectors are available in IPM 2.6?
• For TCP Connect operations, what port numbers does IPM support?
• For UDP operations, what port numbers does IPM support?
• Does IPM provide a default HTTP operation?
• How many data collectors can IPM support?
• Is the IPM database schema published?
• Does IPM support data export?
• In IPM 2.6, why can some commands be run by root only, and others by members of the casusers
group?
• Does DefaultVoice operation uses RTP protocol to measure jitter?
• Can I use NAT/PAT between IPM server and client?
• What are the port numbers used by IPM?
• What is the difference between Active and Passive FTP session modes?
• Does IPM receive traps?
• How do I set SNMP views for the Write community string?
• Can I get historical statistics that are less than an hour?
• What does the “Responder On” field mean in Target Configuration?
Q.
What is IPM?
A.
IPM is an application for measuring and monitoring network performance statistics such as network
latency, jitter, availability, packet loss, and errors. You can view these statistics in real time, or have
IPM store them in its database for historical analysis. You can also use IPM to establish network
baselines and monitor thresholds.
Q.
Does IPM require a dedicated hardware probe to measure and monitor network performance
statistics?
A.
No. IPM utilizes the Service Assurance (SA) Agent software feature embedded in the Cisco IOS
software.
Q.
Does the IPM application take measurements from the point of view of the management
workstation?
A.
No. IPM configures the SA Agent feature embedded in the Cisco IOS software to take
measurements. The measurements are taken within the network rather than from the management
workstation.
