IPM FAQs
Q.
For UDP operations, what port numbers does IPM support?
A.
For UDP connections, valid port numbers are 7, and 1025 to 65535.
If the target device is a Cisco router running version 12.1 or later of the Cisco IOS software, you can
specify any port that is not well known (that is, you can specify any port number greater than 1024)
to communicate with the SA Agent Responder, as long as someone is listening on that port on the
target. The only allowed well known port is UDP port 7.
If the target is not running version 12.1 or later of the Cisco IOS software, whether a Cisco or a
non-Cisco IP host, you must specify UDP port 7 as the target port.
Q.
Does IPM provide a default HTTP operation?
A.
No. You must create your own HTTP operations. See the Measuring Network Performance for
HTTP for information about creating a new HTTP operation.
Q.
Does IPM provide a default FTP operation?
A.
No. You must create your own FTP operations. See the Measuring Network Performance for FTP,
page 3-15 for information about creating a new FTP operation.
Q.
How many data collectors can IPM support?
A.
There is no functional limit on the number of collectors that IPM can support. However, we
recommend you limit the maximum number of collectors per IPM server to 1000. To support more
than 1000 collectors, you can deploy multiple IPM servers. Many users deploy an IPM server in each
geographic area of their network.
Q.
Is the IPM database schema published?
A.
Yes. The IPM database schema is available on the IPM product CD, in the docs directory.
Q.
Does IPM support data export?
A.
Yes. IPM supports export to comma-separated value files, as well as to HTML files.
Q.
In IPM 2.6, why can some commands be run by root only, and others by members of the casusers
group?
A.
Members of the casusers group will not have permissions to run all commands. IPM allows only the
user with administrative privileges to run all commands. For users to run any IPM command, they
must be a member of the group, casusers.
Q.
Does DefaultVoice operation uses RTP protocol to measure jitter?
A.
No. It uses UDP (User Datagram Protocol).
Q.
Can I use NAT/PAT between IPM server and client?
A.
No. IPM does not support Network Address Translation (NAT), Port Address Translation (PAT) and
between client and Server.
