Configuring the PA-FC-1G
To continue your port adapter installation, you must configure the fibre channel interface. The instructions that follow apply to all supported platforms.
This chapter contains the following sections:
•
Using the EXEC Command Interpreter
•
Using the EXEC Command Interpreter
You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or change the existing configuration of an interface. The system prompts you for a password if one has been set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level:
Step 1
Router> enablePassword:Step 2
When you enter the correct password, the system displays the privileged-level system prompt (#):
Router#To configure the new fibre channel interface, proceed to the "Configuring the Interfaces" section.
Configuring the Interfaces
Because a PA-FC-1G interface is one of many components in a fibre channel fabric, configuring a PA-FC-1G requires more than assigning an IP address to the PA-FC-1G. Figure 4-1 indicates the logical connections among the main components in a fibre channel fabric. (For the purposes of this section, only the fibre channel switch component of the fibre channel SAN is shown.)
Figure 4-1 shows the TCP tunnel that connects routers in a fibre channel over IP configuration. It also shows the B_port to E_port fibre channel connection between the routers and fibre channel switches.
Figure 4-1 Fibre Channel Fabric Logical Connections
To configure a PA-FC-1G, you must complete a series of tasks in a particular order. The following tasks are presented in the order in which you perform them:
•
•
•
•
•
•
Connecting a PA-FC-1G to a Fibre Channel Switch
The first task in configuring a PA-FC-1G is to establish a physical connection between the PA-FC-1G and the fibre channel switch that connects the PA-FC-1G to a fibre channel SAN. Perform this task for each PA-FC-1G in the fibre channel fabric.
To connect a PA-FC-1G to a fibre channel switch, do the following:
Step 1
Step 2
Enabling a PA-FC-1G
After verifying a physical connection between a PA-FC-1G and a fibre channel switch, you must assign an IP address to the PA-FC-1G and then enable it. Perform this task for each PA-FC-1G in the fibre channel fabric.
To enable a PA-FC-1G, do the following:
Step 1
Step 2

Default Configuration Values
When an interface is enabled (taken out of shutdown mode) with no additional arguments, the default interface configuration file parameters are operational. Table 4-1 shows PA-FC-1G default configuration values. The default maximum transmission unit (MTU) is the maximum MTU allowed. Decreasing the MTU is not recommended because it will decrease throughput. IP fragmentation is not supported.
Table 4-1 PA-FC-1G Default Configuration Values
MTU
[no] mtu <mtu>
1500
IP MTU
[no] ip mtu <ip-mtu>
1500
Table 4-2 shows TCP tunnel default configuration values. IP TOS is used as part of the overall QoS design to prioritize traffic. For example, to give fibre channel over IP traffic a higher priority than web traffic, set the IP TOS for fibre channel over IP traffic to a number that is lower than the number assigned to IP TOS for web traffic. The lower the number, the higher the priority.
Maximum Window Size Recommendations
When you configure the TCP tunnel, you will need to customize the maximum window size (MWS) for the TCP connection based on the delay across the WAN connection. The larger the delay, the larger the window size needs to be.
If there is no delay across the WAN connection, set the MWS based on these guidelines:
•
•
•
If there is delay across the WAN connection, use an MWS appropriate for the delay. Performance is measured in megabytes per second. Table 4-3 shows that increasing the window size when the delay is large has a significant effect on performance.
Setting Fibre Channel Fabric Timeout Values
Timeout values are defined on each fibre channel switch in a fibre channel fabric. The default error detection (E_D_TOV) and resource allocation (R_A_TOV) timeout values are usually low. You might need to increase them; set the timeout values as appropriate for your SAN and applications.
Timeout values must be configured identically on each fibre channel switch in the fabric. While the TCP tunnel might come up if the timeout values on the switches are not configured identically, this is an exceptional case, and performance and reliability can suffer.
Failure to establish the TCP tunnel (due to mismatched timeout values or any other reason) means that the PA-FC-1G cannot communicate with any part of the fibre channel fabric.
Creating and Configuring a TCP Tunnel
After establishing a physical connection between each PA-FC-1G and a fibre channel switch and after enabling the PA-FC-1G, the next task is to create and configure a TCP tunnel between two PA-FC-1G interfaces. Creating a TCP tunnel establishes a fibre channel over IP connection between two routers.
Note
To create and configure the TCP tunnel, do the following:
Step 1
Router# configure terminalEnter configuration commands, one per line. End with CNTL/Z.Router(config)# interface fcpa 2/0Router(config-if)#Step 2
Router(config-if)# fc-tunnel abcRouter(config-if-fc-tunnel)#Step 3
On one end of the tunnel:
Router(config-if-fc-tunnel)# srp-ip 10.1.1.2Router(config-if-fc-tunnel)# dest-ip 10.2.2.2On the other end of the tunnel:
Router(config-if-fc-tunnel)# srp-ip 10.2.2.2Router(config-if-fc-tunnel)# dest-ip 10.1.1.2Step 4
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 2000Step 5
Step 6
Step 7
Router(config-if-fc-tunnel)# inserviceStep 8
Router(config-if-fc-tunnel)# exitRouter(config-if)# exitRouter(config)# exitRouter#Step 9
Router# copy running-config startup-config[OK]Router#
Changing the TCP Tunnel Configuration
If you need to tune or modify the TCP tunnel configuration after the TCP tunnel is established, you must first take the TCP tunnel out of service using the no inservice command. The following example shows how to change the IP TOS value from 0 to 1 for an established tunnel.
Router(config-if)# fc-tunnel abcRouter(config-if-fc-tunnel)# no inserviceRouter(config-if-fc-tunnel)# ip tos 1Router(config-if-fc-tunnel)# inserviceConfiguring for Multiple SANs
Two fibre channel SANs can be connected by establishing a TCP tunnel between two PA-FC-1G interfaces, each residing in a separate router. Additional PA-FC-1G interfaces can be installed in each router and multiple TCP tunnels can be configured, thus allowing multiple fibre channel SANs to be interconnected.
However, additional TCP tunnels must be defined using different PA-FC-1G port adapters, different IP addresses on different subnets, different source and destination TCP tunnel IP addresses, and different source and destination TCP tunnel ports.
Verifying TCP Tunnel Connectivity
Verifying TCP tunnel connectivity requires checking that the TCP tunnel is correctly configured and verifying that the TCP tunnel is working properly. To verify TCP tunnel connectivity, proceed with the following tasks:
•
•
Checking TCP Tunnel Configuration
Check the TCP tunnel configuration using the show fc-tunnel command. Verify that the values shown are those you defined. Make sure that the TCP tunnel is in service, the ARP entry is installed, the SM (session manager) state is up, and the FC Link is up.

Check that the TCP tunnel is established using the show fc-tunnel tcpconn command. Make sure that t_state is indicated as TCPS_ESTABLISHED. (With the exception of t_state, the output of this command is for debugging purposes only.)

Check the TCP tunnel fibre channel statistics for errors using the show fc-tunnel fc-statistics command.
Verifying PA-FC-1G to Fibre Channel Switch Connectivity
Check the connectivity between each PA-FC-1G and the fibre channel switch by using the show fc-tunnel detail command. Make sure that elp_completed is indicated as 1. This means that an exchange link parameter has been received by the router from the fibre channel switch and that the B_port on the router has been successfully initialized.
Note that in addition to the information shown in the show fc-tunnel command output, the show fc-tunnel detail command output indicates a reason why the connection between the PA-FC-1G and the fibre channel switch was closed (Last close reason) and port information.
Verifying End-to-End Fabric Connectivity
Check that the fibre channel fabric is complete by making sure any fibre channel switch can see all other switches in the fibre channel fabric. On most fibre channel switches, this can be done using a type of show command. For example, on the Cisco SN 5428, use the show fcswitch fabric brief command. On an MDS 9000 fibre channel switch, use the show fspf database and show fcdomain commands.
Closing or Removing a TCP Tunnel
Table 4-4 summarizes the commands you can use to close or remove a TCP tunnel.
Command examples are based on the following configuration for a TCP tunnel called abc:

Using show Commands to Verify the New Interface Status
This section demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the port adapter appears in them correctly. Sample displays of the output of selected show commands appear in the sections that follow. For complete command descriptions and examples, refer to the publications listed in the "Related Documentation" section on page viii.
If an interface is shut down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the interface is properly connected and terminated. If you still have problems bringing up the interface, contact a service representative for assistance. This section includes the following subsections:

Using the ping command, you can verify that an interface port is functioning properly. This section provides a brief description of this command. Refer to the publications listed in the "Related Documentation" section on page viii for detailed command descriptions and examples.
The ping command sends echo request packets out to a remote device at an IP address that you specify. After sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate a bad connection.
Following is an example of a successful ping command to a remote server with the address 10.0.0.10:
Router# ping 10.0.0.10 <Return>Type escape sequence to abort.Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:!!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 msRouter#If the connection fails, verify that you have the correct IP address for the destination and that the device is active (powered on), and repeat the ping command.
Pinging the PA-FC-1G
After the PA-FC-1G is enabled using the no shut command, pinging the PA-FC-1G IP address should be successful. Pinging the TCP tunnel source and destination IP addresses is successful only after the TCP tunnel has been brought into service using the inservice command.
