Determining Platform Support Through Cisco Feature Navigator
Cisco IOS software is packaged in feature sets that are supported on specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.
Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.
To access Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions found at this URL:
Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:
Availability of Cisco IOS Software Images
Platform support for particular Cisco IOS software releases is dependent on the availability of the software images for those platforms. Software images for some platforms may be deferred, delayed, or changed without prior notice. For updated information about platform support and availability of software images for each Cisco IOS software release, refer to the online release notes or, if supported, Cisco Feature Navigator.

Information About the PA-FC-1G Fibre Channel Port Adapter
The PA-FC-1G is a single-width, Peripheral Component Interconnect (PCI) port adapter designed to tunnel fibre channel frames through TCP connections, guaranteeing reliable transport of storage area network (SAN) traffic over IP-based WANs.
The PA-FC-1G provides a single one gigabit fibre (1 Gb) channel interface to the external networks and a single PCI interface into 7200 VXR and 7401ASR routers. (See Figure 1.) It offers an alternative technology to carry SAN traffic over long distances without requiring a dedicated fibre channel network and delivers aggregate throughput of up to 800 Mbps.
Fibre Channel Internet Protocol
The Fibre Channel over TCP/IP (FCIP) is a tunneling protocol that connects geographically distributed fibre channel storage area networks (SANs) transparently over local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs).
Figure 1 FC SAN Traffic Over an IP Network
The Transmission Control Protocol (TCP) handles congestion control and congestion management, and data error recovery and data loss recovery for FCIP. TCP/IP handles transportation for FCIP, while maintaining fibre channel (FC) services.

Defaults
No default behavior or values.
Command Modes
Privileged EXEC
Command History
Usage Guidelines
Under heavy traffic, do not enable debug fcpa cordova-driver packets, debug fcpa northstar-driver events, or debug fcpa northstar-driver extra, because these debug commands will degrade performance and make the console unusable.
Examples
The following example shows some possible variations of the debug fcpa command:
Router# debug fcpa all errors Router# debug fcpa fd events Router# debug fcpa fcap events Router# debug fcpa fcap extra Router# debug fcpa fd statesdest-ip
To specify the destination TCP tunnel IP address, use the dest-ip command.
dest-ip IP address
Syntax Description
Defaults
No default behavior or values.
Command Modes
Privileged config
Command History
Usage Guidelines
Use this command to specify the IP address of the destination TCP tunnel.
Examples
The following example shows the dest-ip command:
Router(config-if-fc-tunnel)# dest-ip 10.2.2.2dest-port
To set the destination TCP port of the FCIP tunnel, use the dest-port command.
dest-port port
Syntax Description
Defaults
No default behavior or values.
Command Modes
Privileged config
Command History
Usage Guidelines
Use this command to set the destination TCP port of the FCIP tunnel. The source and destination ports on one end of the TCP tunnel must match the destination and source ports on the other end of the TCP tunnel, respectively.
Examples
The following example shows the dest-port command:
On one end of the tunnel:
Router(config-if-fc-tunnel)# src-port 2000Router(config-if-fc-tunnel)# dest-port 3000On the other end of the tunnel:
Router(config-if-fc-tunnel)# src-port 3000Router(config-if-fc-tunnel)# dest-port 2000fc-tunnel
To create an fc tunnel, use the fc-tunnel command in FCPA interface configuration mode. To disable the fc-tunnel, use the no form of this command.
