Managing Ports
This section describes the following tasks that manage ports and devices:
5.1
Displaying Port Information
Port information is available primarily in the faceplate display shown in Figure 5-1
.
The faceplate display data windows provide information and statistics for switches and ports. Use the topology display to view status information on fabrics, switches, and links between switches.

Port operational state
Port speed
Port media
To display port number and status information for a port, position the cursor over a port on the faceplate display. The status information changes depending on the
View menu option selected.

Changing Port Administrative States
The port administrative state determines the operational state of a port. The port administrative state has two forms: the configured administrative state and the current administrative state.
The configured administrative state is the state that is saved in the switch configuration and is preserved across switch resets. SANsurfer Switch
Manager always makes changes to the configured administrative state.
The current administrative state is the state that is applied to the port for temporary purposes and is not preserved across switch resets. The current
administrative state is set using the Set Port command. Refer to the ”Set
.
Table 5-7 describes the port administrative states. To change port administrative
state, do the following:
1.
Select one or more ports in the faceplate display.
2.
Open the Port menu and select Port Properties or Port Properties 10G to open the Port Properties dialog.
3.

Using the Extended Credits Wizard
5.3
Using the Extended Credits Wizard
Each port is supported by a data-buffer with a 16-credit capacity; that is, 16 maximum sized frames. For fiber optic cables, this enables full bandwidth service over a distance of 26 kilometers at 1-Gbps (0.6 credits per Km), 13 kilometers at
2-Gbps (1.2 credits per Km), or 6 kilometers at 4-Gbps (2.4 credits per Km).
Longer distances can be spanned at full bandwidth by borrowing credits from designated donor ports thus pooling the buffer capacities. This is called credit extension. Each donor port contributes 15 credits to the pool from which the recipient ports can draw. The recipient port also loses one credit in the process.
For example, one donor port contributes 15 credits to the pool from which a recipient draws for a total of 30 credits (15+15). This provides approximately 50
Km at 1-Gbps (30÷0.6), 25 Km at 2-Gbps (30÷1.2), or 13 Km at 4-Gbps (30÷2.4).
Only 1-Gbps/2-Gbps/4-Gbps ports can donate or borrow credits. To extend credits, open the Wizards menu and select Ext Credit Wizard. The Extended
Credit Wizard leads you through the following process to extend credits based on transmission distance requirements:
1.
Extended Distance: Explains the concepts and principles of extending port credits. Click the Next button.
2.
Extended Distance Requirements: Specify speed and distance requirements for each port then click the Next button.
3.

Note: As credits are used, the Logged-In LEDs on the corresponding donor ports illuminate continuously. In addition, donor port Activity LEDs will reflect the same traffic as the recipient port. Donor ports whose credits are being used are unavailable to devices that are connected to them.
5.4
Resetting a Port
The Reset Port option reinitializes the port using the saved configuration. To reset a port, do the following:
1.
In the faceplate display, select the port(s) to be reset.
2.
Open the Port menu and select Reset Port.
5.5
Testing Ports
The port loopback tests verify correct port operation by sending a frame out through the loop, and then verifying that the frame received matches the frame that was sent. Only one port can be tested at a time for each type of test. The Port
Loopback Test dialog shown in
Figure 5-4 presents the following loopback tests:

Testing Ports
SerDes level (Internal) - The SerDes level test verifies port circuitry. The
SerDes level test sends a test frame from the ASIC through the SerDes chip and back to the ASIC for the selected ports. The port passes the test if the frame that was sent by the ASIC matches the test frame that was received.
This test requires that the port be in diagnostics mode, and therefore, disrupts communication.
SFP level (External) - The SFP level test verifies port circuitry. The SFP level test sends a test frame from the ASIC through the SerDes chip, through the SFP transceiver fitted with an external loopback plug, and back to the ASIC for the selected ports. The port passes the test if the test frame that was sent by the ASIC matches the test frame that was received. This test requires that the port be in diagnostics mode, and therefore, disrupts communication.
Node-to-Node (Online) - The Node-to-Node test verifies communications between the port and its device node or device loop. The port being tested must be online and connected to a remote device. The port passes the test if the frame that was sent by the ASIC matches the frame that was received.
This test does not disrupt communication on the selected port. This test requires that the port be online, and therefore, does not disrupt communication.
To run the internal, external, or online port loopback test on a port, do the following:
1.
In the faceplate display, select the port to be tested.
2.
Open the Port menu and select Port Loopback Test to open the Port
Loopback Test dialog.
3.
In the Test Selection area, click the radio button for the type of loopback test to be run (Internal, External, or Online). If you choose the internal or external test, SANsurfer Switch Manager will prompt you to confirm that the port state needs to be changed to the diagnostic state. Click the OK button and
SANsurfer Switch Manager will change the port state.
4.
Enter the frame count, frame size, and click a test pattern radio button. You may use the default pattern or enter an 8-digit pattern (hex). For online test, you can check the Terminate Test Upon Error check box if you want the test to stop should it encounter an error.
5.
Click the Start Test button to begin the test. The Test Results area displays the test status, number of frames sent, and number of errors found.
6.
To test another port, open the Select Port pull-down menu and select another port (number) and test type (Internal, External, or Online) in the Test
Selection area.

Graphing Port Performance
SANsurfer Performance Viewer application displays port performance using graphs. SANsurfer Performance Viewer plots data communication rates and total errors for selected ports as shown in
. When graphing data communication rates, you can choose either frames/second or KB/second.
On Solaris platforms, if you launch the SANsurfer Performance Viewer application from the SANsurfer Switch Manager application and SANsurfer Performance
Viewer can not connect to the fabric, (for example, if you have reached the maximum number of SANsurfer Switch Manager sessions on the entry switch), then SANsurfer Performance Viewer opens with a blue fabric icon displayed in the fabric tree.
Fabric status is displayed in text format after the fabric name in the fabric tree. The color of the icon indicates the current connection status as normal (green), warning (yellow), critical (red), or unmanageable (blue).

Exiting SANsurfer Performance Viewer
To exit a SANsurfer Performance Viewer session, open the File menu and select
Exit. The current fabric view is automatically saved to your default performance view file upon exit, if you have defined an encryption key. The key is encrypted and saved with your default performance view file. A performance view file contains the set of fabrics that have been added and the graphs that have been opened during a SANsurfer Performance Viewer session. If you have not yet defined an encryption key, the Save Default Performance View File dialog, shown
in Figure 5-6 , prompts you to save the current performance view file as the default
performance view file. Refer to ”Changing the Default Performance View File
Encryption Key” on page 5-22 for information about defining and changing this
encryption key.
In the Save Default Performance View File dialog, enter an encryption key in the
Default Performance File Encryption Key field. Re-enter the encryption key in the
Re-enter Encryption Key to Confirm field. Click the OK button to save the current set of fabrics to the default performance view file in the working directory.
To prevent SANsurfer Performance Viewer from prompting you to save the default performance view file between sessions, set the Auto Load and Save Graphing
Environment setting to Enable (default). Refer to ”Setting SANsurfer Performance
