Qbin Statistics
Qbin Statistics
Qbin statistics allow network engineers to properly engineer and overbook the network on a per
Class-of-Service (or per Qbin) basis.
Switch software collects statistics for the following:
• BXM Automatic Routing Management Qbin (Qbin numbers 1 to 9) on Automatic Routing
Management trunks.
•
Qbin numbers 10 to 15 assigned for use by VSI traffic. These statistics are helpful for configuring
MPLS or PNNI controllers.
The resulting statistics are displayed in Cisco WAN Manager and may also be viewed by using the
command line interface (CLI).
The following are the Qbin statistics:
• cells served
•
cells received
• cells discarded
Because all Qbins provide the same statistical data, the Qbin number together with its statistic forms a
unique statistic type. One unique statistic type is “Cells served out of Qbin-10.” Another unique statistic
type is “Cells discarded by Qbin-11,” and so on.
Trunk and port counter statistics for Qbins 1 to 15 can be collected by SNMP.
Qbin summary and counter statistics can be enabled as TFTP or USER (not AUTO) interval statistics.
Unlike the cell discard statistics on BXM trunk Qbins 1 to 9, all cell-discard statistics on Qbins 10 to 15
are not AUTO statistics.
The next two sections are a brief introduction the commands described in the Cisco WAN Switching
Command Reference. For detailed explanations and tables of Qbin statistics, see the Qbin commands in
the Cisco WAN Switching Command Reference and the Cisco WAN Manager User’s Guide.
Interval Statistics
The following are the two ways you can collect interval traffic statistics (per Qbin) on the switch:
•
Cisco WAN Manager’s SCM collects and views statistics on all BXM trunks on a BPX (TFTP
statistics). See the Cisco WAN Manager documentation.
•
The command line interface (CLI).
Table 27-8 lists the commands that are used to collect interval statistics.
