Configuring and Collecting Statistics
Configuring statistics speci fies to th e shelf where statistic counter s ar e to be collected. A file is
constructed that lists the s tatistic counters to be coll ected and is downloaded into th e shelf using TCP/IP
TFTP.
Collecting statistics cause s the statistics to be transfer r ed as a data file to the workstation. Th e
workstation first requests the statistics and the Cisco MGX 8220 shelf responds by uploading the
statistic file to the workst ation. A list of statistics cou nters for each card type is pr ovided in Appendix B,
“Specifications.”
The method of collecting statistics in Cisco MGX 8220 conforms to the standards employed in IGX,
IPX, and Cisco BPX nodes. CWM (Release 7.2 and later) supports the standard TFTP method of
configuring and collecting stat isti cs and can be used on the work stat io n th at is attached to the Cisco
MGX 8220 shelf for this purpo se. CWM provides a convenient and easy-to -use graphical user interface
(GUI) for both configuring the stat istics to be collected and actually collecting those statistics from th e
Cisco MGX 8220 shelf. Using CWM relieves the user of knowing and constructing the file formats
required for correctly transfe rr ing th e statistics files.
Each type of statistic collected in WAN switching networks is categorized under a major grouping
known by an object type name and an object type number, and minor grouping known as a subtype.
Within the subtype, the statisti c has a statistic type number. For examp le, the statistic “ATM Cell Header
HEC Errors” has an object type name of IPX-ATM, an object type of 2, a subtype of 1, and a statistic
type of 45. This combination of groups and type number uniquely identify a par ticular type of statistic.

Configuring Statistics

Each Cisco MGX 8220 statistic can be configured individually for collection. To configure statistics,
the workstation transfers a file ( file na me = enable.stats) using TF TP to th e Cisco MGX 8220 shelf,
which specifies those statist ic types to be collected. The spec ified statistics are grouped by objec t type,
then by object subtype. M ult ipl e obje ct t ype s e ach cont a inin g mul t iple ob jec t subt yp es, e a ch c onta in ing
multiple statistic types ca n b e specified in one file.

Collecting Statistics

To collect statistics from the Cisco MGX 82 20 shelf, the workstation uses the follow ing TFTP command
to issue a request:
Get Nodename.mmddyyhhmm
•Nodename is the node name given to the Cisco MGX 8220 shelf.
•mmddyyhhmm is the date/time expressed in G M T.
Upon receipt of this message , the shelf responds with a file containing the collected statist ics, as shown
in Table 3-2.
