DT-6X60 User's Manual - Platform (Build 2.0)
10 APPENDIX D: T HE D ISPLAY
M EASUREMENTS ( DM ) R EPORT
The DT-6X60 platform maintains measurements of network activity as an aggregate of all the
application instances. The measurements are grouped into four categories: IP, TCP, UDP, and
ICMP. Many of these measurements are related to variables included in MIB II - Management
Information Base for Network Management of TCP/IP-based Internets (RFC1213).
In the following report samples, the identifiers indicated in red have been added to reference
individual measurements. Information is then provided (in some cases from RFC1213) to describe
each measurement. Measurements that do not have identifiers (mainly in the TCP section) are
those that would be helpful only to developers who are diagnosing problems, but would not be
useful to end users on their own.
Please note that the measurements shown in the following report samples may not be
representative of any particular customer's installation; i.e., the presence of 0's (or non-0's) is not
necessarily an indication of what should be expected.
