FC Analyzer and SPAN for MDS Switches Configuration Example
Available Languages
Contents
Introduction
Similar to the Cisco router product line’s debug capability, the Cisco MDS storage switches have a Fibre Channel (FC) analyzer to examine packets. The FC analyzer examines packets to and from the entities that the switch provides. The FC analyzer is able to debug frames that the switch is responsible for receiving or sending to a storage device. Frames between end stations can not be examined by the FC analyzer.
To examine session flow, the Switched Port Analyzer (SPAN) functionality of the MDS switches should be used. Much like the SPAN function on a Cisco Ethernet switch, SPAN on the MDS product line replicates data to SPAN destination ports, so that it can be collected by a third-party device.
Prerequisites
Requirements
There are no specific requirements for this document.
Components Used
The information in this document is based on these software and hardware versions:
-
Cisco MDS 9216 Switch
-
Cisco MDS 9509 Switch
-
Both run Storage Area Networking Operating System (SAN-OS) 1.2.1a.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Conventions
For more information on document conventions, refer to the Cisco Technical Tips Conventions.
Background Theory
You must know when to use the FC analyzer tool and when to use the SPAN feature.
The FC analyzer is a tool that collects frames that are destined to or originate from the MDS supervisor. Node-to-switch or switch-to-switch traffic can be seen with this tool.
The SPAN is a feature that allows frames that are transient to the switch to be copied to a second port for analysis. Node-to-node traffic can be seen with this method.
Refer to this diagram for an illustration:
The green arrows show traffic that can be traced with the FC analyzer tool, while the pink arrow shows traffic that can be captured with the SPAN method. Traffic from the host to the storage can not be observed by the FC analyzer. Only traffic from the host to the switch or from the switch on the right can be seen, when you run the FC analyzer on the switch on the left.
SPAN can be used to trace traffic in (ingress) and out (egress) of any port on the switch. Remote SPAN (RSPAN), as shown in the previous diagram, can be used to collect frames in and out of the host port on the left switch, with the analyzer attached to the right side switch.
Configure
In this section, you are presented with the information to configure the features described in this document.
Note: To find additional information on the commands used in this document, use the Command Lookup Tool (registered customers only) .
Configuring Local FC Analyzer
Note: The intent is to collect FC frames that originate from, or are destined to, the 9612 supervisor. Frames from the host to JBOD are not collected with the FC analyzer tool.
FC analyzer local is run from the command-line interface (CLI) via console attachment or Telnet. You may run a brief display to show only a small portion of each frame, or you may run a detailed trace to show the entire frame.
The trace is started while in configuration mode, and it is stopped when you press Ctrl-C. By default, only 100 frames are captured. To capture more than 100 frames, add the limit-captured-frames command option to the command that you use to start the trace.
You may also use a display filter to limit the output of the trace to only specific frames.

Configuring for Remote FC Analyzer
Note: The intent is to collect FC frames that originate from, or are destined to, the 9612 supervisor. Frames from the host to JBOD are not collected with the FC analyzer tool.
FC analyzer remote is run on a PC that is using Ethereal 
0.9(9) or later and WinPcap . The IP address of the PC is specified in the command that is issued to start the FC analyzer trace on the MDS CLI. On the PC, Ethereal must also be started from the command line, and the IP address of the MDS management interface must be specified in the command.
-
To stop the MDS FC analyzer trace, you must press Ctrl-C from the CLI.
MDS9216# config t Enter configuration commands, one per line. End with CNTL/Z. MDS9216(config)# fcanalyzer remote 64.102.58.114 MDS9216(config)# ^C
Do not specify the active option on the previous command, or you will need to add additional options to the command line on your PC when you start Ethereal. Adding the active keyword usually means that you have to also configure the TCP port number. It is recommended that you use the defaults.
-
On the PC, verify the IP address, and start the Ethereal remote capture program.

Once the program starts, choose Capture and then click OK to initiate packet collection.
The FC packets that are collected appear as Other in the summary display.
-
Click Stop to halt packet collection and start the trace view portion of the program.
You may use filters to limit the display to a specific traffic stream.
-
If there is problem with the remote capture initiation, you may see an error screen similar to the one in the next image. The FC analyzer is not active on the MDS, or the active keyword was used without a specified port.
Configuring for Local SPAN
Note: The intent is to collect—with the FC analyzer on port 1/15—FC frames to and from the host on port 1/16 of the 9216.
An FC analyzer on port 1/15 shows ordered sets, but not the ordered sets that occur on the link that is being SPANed. The FC analyzer device can be a Port Analyzer Adapter (PAA) and a PC that is running Ethereal, similar to a Finisar device.

Configuring for Remote SPAN
Note: The intent is to collect—with the FC analyzer attached to the 9509—FC frames to and from the host on the 9216. The ST interface must have a Gigabit Interface Converter (GBIC) installed and the speed must match the Span Destination (SD) port on the 9509.
Before you attempt to configure RSPAN, ensure that these points are addressed:
-
All switches must be running MDS code 1.2 or later.
-
No cable should be attached to the Small Form factor pluggable (SFP) in the Span Terminal (ST) port.
-
Make sure that the FC tunnel is UP before you begin to collect frames.
-
FC analyzer can be a PAA and a PC that is running Ethereal, similar to a Finisar device.
If there are any intermediate switches between the SPAN source and the SPAN destination switch, follow this procedure:
-
Create an active VSAN interface in the same subnet as the tunnel source and destination.
-
Enable IP routing.
-
Enable FC-tunneling.
-
Use SAN-OS 1.2 or later.

Notes for Port Analyzer Adapter Devices
The Ethernet port is copper, and it has auto-detects speeds of 1 Gbps or 100 Mbps. Ethereal 0.9(9) or later and WinPcap must be installed on the PC.
The FC port requires an SFP and an LC-to-LC cable for attachment to the MDS.
These are switch settings on the PAA:
-
Switch positions are numbered 1, 2, 3, and 4 from left to right.
-
In the next list, a 1 indicates that the dip switch is ON or UP. A 0 indicates the dip switch is DOWN or OFF.
0001 1G NTM 1001 1G ETM 0101 1G STM 0011 1G DTM 0000 2G NTM 1000 2G ETM 0100 2G STM 0010 2G DTM 1111 1G MNM !--- Used for diagnostics only.
-
Switch 4 dictates the speed (on = 1G, off = 2G). Switches 1, 2, and 3 dictate truncate mode. Any changes require a power cycle.
These are the modes:
-
No Truncate Mode (NTM)—FC frames are passed without any modifications.
-
Ethernet Truncate Mode (ETM)—Reduces the payload size from 528 lines to 368 lines, to truncates FC frame to a maximum of 1496 bytes.
-
Shallow Truncate Mode (STM)—Reduces the payload size from 528 lines to 58 lines, to truncates FC frame to a maximum of 256 bytes.
-
Deep Truncate Mode (DTM)—Reduces the payload size from 528 lines to 10 lines, to truncates FC frame to a maximum of 64 bytes.
