Troubleshooting the Port Analyzer Adapter

The front panel LEDs are the quickest way to evaluate the adapter operation.
Fibre Channel LED Not On
If the green Fibre Channel LED is not on, check to see if the GBIC is fully inserted. Try removing and
reinstalling the GBIC. See the appropriate Cisco MDS hardware installation guide for installation of the
required chassis.
Ethernet Link LED Not Blinking
If the Fibre Channel link is up but the Ethernet link LED is not blinking, do the following:

Setting Up the Cisco Traffic Analyzer
The 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 adapters can be analyzed
concurrently with a single PC running nTop software, which is public domain software enhanced by
Cisco for Fibre Channel traffic analysis.
This traffic analysis solution enables throughput to be determined for traffic between specific Fibre
Channel sources and destinations, for all traffic in a particular virtual SAN (VSAN), or for all SPAN
traffic. The following information is provided: round trip response times, SCSI I/Os per second, SCSI
read versus write traffic throughput and frame counts, and SCSI session status and management task
information. Additional statistics are also available on Fibre Channel frame sizes and network
management protocols.
For seamless performance analysis and troubleshooting, launch the Cisco Traffic Analyzer in-context
from Cisco Fabric Manager. Port world wide name (pWWN), Fibre Channel ID (FC ID), FC alias, and
VSAN names are then passed to the Cisco Traffic Analyzer.
Accessing Cisco Traffic Analyzer changed with Fabric Manager Release 2.1(2). You can still run Cisco
Note
Traffic Analyzer from Fabric Manager Web Services. However, with Fabric Manager Release 2.1(2) or
later, you can no longer access Cisco Traffic Analyzer from the Fabric Manager Client. For more
information on releases prior to Fabric Manager Release 2.1(2), see the
Analyzer from Fabric Manager Web Services" section on page
The nTop software runs on a host, such as a PC or workstation running Windows or Linux. This software,
which supports VSANs and Fibre Channel decoding through the adapter, includes enhancements
provided by Cisco to the public domain.

Verify that the SD port and the adapter are configured to be the same speed.
Verify that the SD port is sending out Fibre Channel frames by looking at the SPAN interface
counter.
