Overview
The PAA enables effective, low-cost analysis of Fibre Channel traffic. The device is a standalone Fibre
Channel-to-Ethernet adapter, designed primarily to analyze Fibre Channel Switched Port Analyzer
(SPAN) traffic from a Fibre Channel port on a Cisco MDS 9000 Family switch. The main function of the
adapter is to encapsulate Fibre Channel frames into Ethernet frames. This encapsulation allows low-cost
analysis of Fibre Channel traffic while leveraging the existing Ethernet infrastructure.
The PAA allows you to examine Fibre Channel frames of various sizes. Fibre Channel frames from
Layers 2, 3, and 4 may be examined without network disruption.

Overview
The PAA works in conjunction with the SPAN feature on the Cisco MDS 9000 Family of switches. The
SPAN feature allows storage network administrators to nondisruptively replicate any port’s traffic to any
other port that is programmed as a SPAN destination(SD port). It encapsulates the Fibre Channel frames
from the SD port into Ethernet frames that can be analyzed on a PC. Storage administrators can
troubleshoot the network quickly and cost-effectively, with no network disruption.
You can copy frames using the Cisco Protocol Analyzer or the Cisco Traffic Analyzer. The Cisco
Protocol Analyzer is a modified version of Ethereal, and the Cisco Traffic Analyzer is a modified version
of nTop, a network traffic probe. Both analyzers are modified to support Fibre Channel and SCSI.
Note Additional information about Ethereal is available at http://www.ethereal.com, and additional
information about the Cisco Traffic Analyzer is available at
http://www.cisco.com/kobayashi/sw-center/sw-stornet.shtml.
The PAA sets appropriate bits in the encapsulated trailer to indicate different types of errors (for
example, CRC-errors, empty frame, jumbo frame, or other errors) during a data transfer. Both the Cisco
Protocol Analyzer and the Cisco Traffic Analyzer can decode these packets, but they do so for different
purposes. The Cisco Traffic Analyzer decodes packets for traffic analysis, and the Cisco Protocol
Analyzer decodes packets for protocol analysis.
The adapter has two primary interfaces:
•A Fibre Channel interface that operates at 1-Gbps or 2-Gbps
•A 100/1000-Mbps Ethernet port
Note The 1-Gbps and 2-Gbps Fibre Channel links do not support auto negotiation. You must explicitly
configure the link speed.

Figure 1 Cisco MDS 9000 Family Port Analyzer Adapter Network Topology Example
Installation Requirements
Before using the adapter in a network, verify the following:
•The Fibre Channel port on the Cisco MDS 9000 Family switch must be configured as an SD port,
as described in the Cisco MDS 9000 Family CLI Configuration Guide or the Cisco MDS 9000 Family
Fabric Manager Guide. For more information, see the “Cisco MDS 9000 SPAN Usage Instructions”
section on page 4.
•Cisco Traffic Analyzer or Cisco Protocol Analyzer must be installed on the PC attached to the
adapter, as described in the “Setting Up the Cisco Traffic Analyzer” section on page 15 and the
“Setting Up the Cisco Protocol Analyzer” section on page 22.
•The adapter must be used in one of four truncate modes, which can be set using the four Dual Inline
Package (DIP) switches on the rear of the unit. See the “Modes of Operation” section on page 7 for
the correct mode.
•The Fibre Channel interface on the adapter must then be connected to the Fibre Channel SD port on
the Cisco MDS 9000 Family switch.
•The Ethernet interface adapter must be connectedeither to the host that is using Cisco Traffic
Analyzer or Cisco Protocol Analyzer software, or to an Ethernet switch. The host performing the
capture must be attached to the same switch in the same VLAN as the PAA.

Overview
Cisco MDS 9000 SPAN Usage Instructions
On the Cisco MDS 9000 Family switch, traffic through any Fibre Channel interface can be replicated to
an SD port. When a port is configured in SD mode, a copy of traffic (ingress, egress, or both) from a set
of configured ports is sent to the SD port.
Tip Configure the extended inter-switch link (EISL) mode using the switchport encap eisl command if you
need to debug or analyze VSAN-specific information.
Note For information on configuring the SPAN feature, see the Cisco MDS 9000 Family CLI Configuration
Guide.
A valid Fibre Channel port on a Cisco MDS 9000 Family switch must be configured as an SD port. Once
a Fibre Channel port is in SD port mode, it cannot be used for normal data traffic.
In SD port mode, the Fibre Channel port of the switch has the following characteristics:
•Packets are always output from the port (egress). The port never receives any frames.
•The port cannot be flow-controlled.
•No handshaking is performed.
•The receiving device does not need a Fibre Channel address.
The following usage considerations apply to a PAA connected to a Cisco MDS 9000 Family switch:
•The adapter receives data only; the adapter does not transmit data to the switch.
•The LED on the Fibre Channel SD port on the switch cannot be used to diagnose a problem.

OL-9077-01
Hardware Description
Power Generation
The PAA requires 12-VDC external power. An AC converter is provided and connects to the power input
at the rear of the unit.
Modes of Operation
The PAA has five modes of operation, four truncation modes and one no-truncate mode. These modes
are used to configure the size of the frames that will be copied from the Fibre Channel interface. The two
factors that are used to determine the setting are:
•The difference in speed of the Ethernet from the Fibre Channel interface.
•The amount of payload required for troubleshooting purposes.
This balance can be achieved by using one of the four truncate modes to increase or decrease the frame
rate at the expense of reducing or increasing the payload. By truncating the Fibre Channel payload, the
adapter can transmit more frames per second on the Ethernet interface.
There are four external DIP switches on the rear of the adapter, numbered 1 through 4, from left to right.
These switches configure the PAA to operate at either 1-Gbps or 2-Gbps Fibre Channel speed in one of
the five modes of operation.
The modes of operation are as follows:
•No truncate mode (NTM)
•Ethernet truncate mode (ETM)
•Shallow truncate mode (STM)
•Deep truncate mode (DTM)
•Management mode (MNM)
A speed mismatch between the Fibre Channel and the Ethernet side of the adapter could affect the frame
throughput on the Ethernet side. For example, if the Fibre Channel speed is set at 2 Gbps, and the
Ethernet speed is set at 1 Gbps, and all packets on the Fibre Channel side are 2164 bytes in size, you
must configure the adapter to DTM or STM mode for the Ethernet side to receive all frames. If the
adapter were in ETM (or NTM) mode, it would drop packets on the Ethernet side, and the Ethereal
Network Analyzer might not see all the frames. Table 2 shows how the DIP switches should be
configured for each Fibre Channel port speed and operating mode.

OL-9077-01
Selecting Truncate Mode
Note The speed does not matter (1 or 2 Gbps) if you place a switch in MNM mode.
Caution Configuring a combination of DIP settings, other than those mentioned in Table 2, may have
unpredictable consequences.
Truncate Mode
If you want to use truncate mode, you need the DS-PAA-2. DS-PAA does not support this.
The Cisco Traffic Analyzer’s Fibre Channel throughput values are not accurate when used with the
DS-PAA if data truncate is enabled. The DS-PAA-2 is required to achieve accurate results with truncate
because it adds a count that enables the Cisco Traffic Analyzer to determine how many data bytes were
actually transferred. By truncating a frame, you can push more packets through the PAA (2 Gbps for
Fibre Channel to 1 Gbps or slower for Ethernet) and preserve privacy of the traffic being captured.
Selecting Truncate Mode
Note Truncate mode is available in DS-PAA version 2 and later.
Table 3 shows an example of how to select the truncate mode according to the average size of the Fibre
Channel frame and the Fibre Channel-to-Ethernet speed. For example, with a 2164-byte Fibre Channel
frame size, 1-Gbps Fibre Channel speed, and 100-Mbps Ethernet speed, you would select DTM mode.

OL-9077-01
Selecting Truncate Mode
The truncate modes can be hot switched (no power off is necessary). However, if you configure a new
speed setting (for example, changing the Fibre Channel port speed from 2 Gbps to 1 Gbps), the adapter
must be power cycled for the new setting to take effect. Power cycling consists of unplugging the adapter
wall plug, waiting for four seconds or more, and then plugging it back in and powering on.
No Truncate Mode (NTM) for Ethernet Encapsulation
In NTM, Fibre Channel frames are encapsulated into Ethernet frames without any modification to the
payload (the full 2164 bytes are transmitted). Ethernet devices must support jumbo frames for this mode
to work; otherwise, the Ethernet MAC may not work properly for the frames larger than the maximum
Ethernet size. Jumbo frames are Ethernet frames greater than 1520 bytes. (See Figure 4.)
Ethernet Truncate Mode (ETM) for Maximum Payload
This mode is appropriate when jumbo frames are not supported by the Ethernet devices. In that case, this
mode provides the maximum amount of Fibre Channel payload within a single Ethernet frame.

Selecting Truncate Mode
Figure 4 Ethernet Frames and the Four Truncate Modes
In ETM, the adapter truncates a Fibre Channel frame to a maximum payload of 1496 bytes on the
Ethernet side. Fibre Channel frames larger than 1496 bytes will be truncated. The Fibre Channel payload
transmitted is 1472 bytes. (See Figure 4.)
Shallow Truncate Mode (STM)
STM provides less payload than ETM but more frames per second. In STM, the adapter truncates the
Fibre Channel frame to 256 bytes. (See Figure 4.) Use this mode when you want more frames per second.
Deep Truncate Mode (DTM) for Most Frames per Second
As a default, the adapter comes configured in DTM mode and 1-Gbps Fibre Channel speed. This mode
should be used when you want the most frames per second. DTM provides less payload than STM but
more frames per second.
In DTM, the adapter truncates the Fibre Channel frame to 64 bytes. The total packet length including the
Ethernet header and trailer is 88 bytes. (See Figure 4.)
Management Mode (MNM) for Troubleshooting
MNM mode should be used only when troubleshooting the PAA. In this mode, the adapter will not accept
any Fibre Channel frames.

OL-9077-01
Selecting Truncate Mode
In MNM, the adapter transmits a fixed 288-byte Ethernet frame that contains debug information for your
use or for technical support calls. When calling technical support, also know the version number of the
adapter . There are two versions of PAA, PAA-1 and PAA-2. If you see the Original Packet Length field
in the debug information (highlighted in Figure 5), you are using a PAA-2. If this field is not present,
you are using PAA-1.
Note The Cisco Traffic Analyzer must not be used with the PAA in MNM mode. The PAA in MNM mode
generates traffic with perpetually changing host addresses; the Cisco Traffic Analyzer stores this
redundant information and eventually runs out of memory.

The modes of operation are as follows:
•No truncate mode (NTM)
•Ethernet truncate mode (ETM)
•Shallow truncate mode (STM)
•Deep truncate mode (DTM)

Troubleshooting the Port Analyzer Adapter
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:
•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.
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.
Note Accessing Cisco Traffic Analyzer changed with Fabric Manager Release 2.1(2). You can still run Cisco
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 “Discovering Cisco Traffic
Analyzer from Fabric Manager Web Services” section on page 20.
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.

Using Cisco Traffic Analyzer with Fabric Manager Web Services
Note See the Cisco MDS 9000 Family Fabric Manager Configuration Guide for information about launching
the Cisco Traffic Analyzer from the Performance Manager details charts. Performance Manager is a part
of the Fabric Manager and is a licensed feature in Cisco SAN-OS Release 1.3(2a) or later.
Caution If data truncate is enabled, the Cisco Traffic Analyzer’s Fibre Channel throughput values are not accurate
when used with DS-PAA. The PAA version is required to achieve accurate results with truncate because
it adds a count that enables the Cisco Traffic Analyzer to determine how many data bytes were actually
transferred.
Tip You can use SPAN to monitor traffic on an interface without any traffic disruption. This feature is useful
in troubleshooting scenarios when traffic disruption changes the problem environment and makes it
difficult to reproduce the problem. See either the Cisco MDS 9000 Family Fabric Manager
Configuration Guide or the Cisco MDS 9000 Family CLI Configuration Guide.
Caution The Cisco Traffic Analyzer must not be used with the PAA in MNM mode.
Using Cisco Traffic Analyzer with Fabric Manager Web
Services
You can run Cisco Traffic Analyzer from within Fabric Manager Web Services in Fabric Manager
Release 2.1(2) or later.
Note As of Fabric Manager Release 2.1(2) and later, you can no longer access Cisco Traffic Analyzer from
Fabric Manager Client. However, you can still run Cisco Traffic Analyzer from Fabric Manager Web
Services. For more information on releases prior to Fabric Manager Release 2.1(2), see the “Configuring
Cisco Traffic Analyzer for Fabric Manager Releases Prior to 2.1(2)” section on page 21.
This section includes the following topics:
•Installing Cisco Traffic Analyzer.
•Launching Cisco Traffic Analyzer.
•Discovering Cisco Traffic Analyzer from Fabric Manager Web Services.
•Accessing Cisco Traffic Analyzer from Fabric Manager Web Services.

Using Cisco Traffic Analyzer with Fabric Manager Web Services
Installing Cisco Traffic Analyzer
You must launch Cisco Traffic Analyzer before you can discover and access it from Fabric Manager Web
Services. At a minimum, you need to provide the directory where Cisco Traffic Analyzer stores its database,
including the RRD files that it creates for trending.
Note Do not use the /tmp directory for storing the Cisco Traffic Analyzer database on UNIX or Linux
workstations. Many distributions of Linux periodically clean up the /tmp directory, thereby affecting
Cisco Traffic Analyzer. Instead you can use the /var/ntop directory.
Verify that you have sufficient space in the partition where the Cisco Traffic Analyzer database is stored.
To install and launch Cisco Traffic Analyzer on a UNIX workstation, follow these steps:
Step 1 Open a browser and go to the following website to access the web page where Cisco Traffic Analyzer is
available:
http://cisco.com/cgi-bin/tablebuild.pl/mds-fm.
Step 2 Download fc-ntop.tar.gz and install it using the instructions at the following website:
http://www.ntop.org.
Step 3 Launch nTop using the following UNIX command:
ntop -P database_directory
where database_directory is the directory where you want Cisco Traffic Analyzer to save its database
files (for example, /var/ntop).
Note If another application uses port 3000, you can change the port that Cisco Traffic Analyzer uses
by entering the following in Step 3:
ntop.exe /c -P tmp -w port_number, where port_number is equal to the port that you want Cisco
Traffic Analyzer to use. Set the port number to 3001 if you want to use SSL. Fabric Manager
Web Services can only detect Cisco Traffic Analyzer if you use port 3000 (the default port).
Step 4 Verify that the Fibre Channel port on the PAA is connected to the SD port on the switch (see Figure 9).

Cisco MDS 9000 Family Port Analyzer Adapter Installation and Configuration Note
OL-9077-01
Using Cisco Traffic Analyzer with Fabric Manager Web Services
c. Right-click nTop and choose properties. You see the Properties dialog box.
d. Set the Start Parameters to -P database_ directory, where database_directory is the directory where
you want Cisco Traffic Analyzer to store its database (for example, D:\ntop\tmp).
Note If launching Cisco Traffic Analyzer as a Windows service, you must specify the complete path
for the database directory using the -P option.
Note If another application uses port 3000, you can change the port that Cisco Traffic Analyzer uses
by entering the following in Step 5:
ntop.exe /c -P tmp -w port_number, where port_number is equal to the port that you want Cisco
Traffic Analyzer to use. Set the port number to 3001 if you want to use SSL. Fabric Manager
Web Services can only detect Cisco Traffic Analyzer if you use port 3000 (the default port).
e. Click Start to start nTop on that interface.
Note Subsequent restarts of the nTop service do not require setting the -i option, unless you are
changing the interface that connects to the PAA.
Step 6 Optionally, choose Admin > Startup Preferences > Capture to set the interface that Cisco Traffic
Analyzer uses after Cisco Traffic Analyzer opens.
Step 7 Select the interfaces that are receiving PAA traffic that Cisco Traffic Analyzer will capture packets on.
Step 8 Verify that the Fibre Channel port on the PAA is connected to the SD port on the switch (see Figure 9).
Step 9 Verify that the Ethernet port on the PAA is connected to the workstation running Cisco Traffic Analyzer.
Step 10 Click Interfaces > SPAN... in Device Manager to configure SPAN on the required switch ports.
Step 11 Click the Sources tab in Device Manager to verify that the Fibre Channel port connected to the PAA is
configured as an SD port. The port mode of the destination interface must be SD.
Step 12 Click the Sessions tab in Device Manager to verify the correct destination and source of traffic (ingress).
Tip To modify the script that launches nTop (ntop.sh or ntop.bat), follow the instructions provided within the
script file. Create a backup of the original script before modifying the file.
—Linux platforms use the shell script path. The nTop output is sent to the syslog file (/var/log/messages
by default).
—Windows platforms use the batch file. The nTop output is sent to a file located in the same directory
as the one from which nTop is launched.
You can remove Cisco Traffic Analyzer as a service by entering the following command at the Windows
command prompt:
ntop.exe /r
