Understanding Cisco Traffic Analyzer

Performance Manager collects Fibre Channel level performance statistics using SNMP to access
counters on Cisco MDS 9000 Family switches. To view detailed SCSI I/O statistics, you need to look at
the data on an SD port with the help of Cisco Traffic Analyzer, which uses the Cisco Port Analyzer
Adapter 2 (PAA-2).
Cisco Traffic Analyzer provides real-time analysis of SPAN traffic or analysis of captured traffic through
a Web browser user interface. Traffic encapsulated by one or more Port Analyzer Adapter 2 products can
be analyzed concurrently with a single workstation running Cisco Traffic Analyzer, which is based on
ntop, a public domain software enhanced by Cisco for Fibre Channel traffic analysis.
Round-trip response times, SCSI I/Os per second, SCSI read or traffic throughput and frame counts,
SCSI session status, and management task information are monitored. Additional statistics are also
available on Fibre Channel frame sizes and network management protocols.
For seamless performance analysis and troubleshooting, Cisco Traffic Analyzer can be launched
in-context from Fabric Manager. Port world wide name (pWWN), Fibre Channel ID (FC ID), FC alias,
and VSAN names are passed to Cisco Traffic Analyzer.
Cisco Traffic Analyzer must be downloaded and installed separately from the following website:
http://www.cisco.com/kobayashi/sw-center/sw-stornet.shtml.
Cisco Traffic Analyzer software is available under the Port Analyzer Adapter link. See the
Cisco Traffic Analyzer" section on page
Cisco Traffic Analyzer for Fibre Channel throughput values are not accurate when used with the original
Caution
Cisco Port Analyzer Adapter (PAA) if data truncation is enabled. PAA Version 2 (product ID
DS-PAA_2) is required to achieve accurate results with truncation, because it adds a count that enables
Cisco Traffic Analyzer to determine how many data bytes were actually transferred.
Refer to the Cisco MDS 9000 Family CLI Configuration Guide for information on configuring the
Note
settings for your SPAN destination port. It is important that the data you collect through this port matches
the data collected by Performance Manager through the mgmt0 port. If the data does not match, you
cannot view Cisco Traffic Analyzer information through a Traffic Analyzer link on the detail page of a
Performance Manager report.
