Cisco MDS 9000 Family Port Analyzer Adapter
Installation and Configuration Note
Text Part Number: OL-9077-01
This document describes the Cisco MDS 9000 Family Port Analyzer Adapter (DS-PAA and DS-PAA2),
and the procedures required to install and configure it. It also describes setting up Cisco Traffic Analyzer
and Cisco Protocol Analyzer solutions. This installation and configuration note includes the following
sections:
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.

    Note 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).

    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.

    5), you are using a PAA-2. If this field is not present, you are using PAA-1. The Cisco Traffic Analyzer must not be used with the PAA in MNM mode. The PAA in MNM mode Note generates traffic with perpetually changing host addresses; the Cisco Traffic Analyzer stores this redundant information and eventually runs out of memory.

    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.
