1. How do I carry out a Scan of a single IP address?
There are 2 ways:
a) If you are running in 'Range' mode i.e. there is a tick on the 'Range' checkbox, then enter an IP address into the 'Start Address' entry field at the top left. Then tab across to the 'End Address' entry field. The entry will be automatically filled with the same IP address that you enterd into the 'Start Address' field. Then click on the 'Start Scan' button at the bottom.
b) If you are running in 'Selectable' mode i.e. there is a tick on the 'Selectable' checkbox, then enter a subnet into the Subnet entry box e.g. 10.77.77 and then using the listbox to the right scroll to the host you wish to scan and select it. Then click on the 'Start Scan' button at the bottom.

2. How do I carry out a Scan of multiple IP address's (Sequentially)?
Make sure that the 'Range' checkbox is ticked. Enter an IP address into the 'Start Address' entry field at the top left. Then tab across to the 'End Address' entry field. The entry will be automatically filled with the same IP address that you enterd into the 'Start Address' field. In the 'End Address' field, change the last digit to something else. For example, changing it to 255 will enable you to Scan up to the end of the subnet. Now click on the 'Start Scan' button at the bottom left.

3. How do I carry out a Scan of multiple IP address's (Non-Sequentially)?
Make sure that the 'Selectable' checkbox is ticked. Enter a subnet into the subnet entry box e.g. 10.77.77 and then using the listbox to the right, select the hosts you wish to scan by holding the Ctrl and/or shift keys and using the mouse to select multiple hosts. Then click on the 'Start Scan' button at the bottom.

4. How do I remove entries found in a Scan?
2 ways: Carry out a new Scan.  When you click on the 'Start Scan' button you will be asked whether or not you want to remove all previously discovered nodes. Select 'Yes'. This will remove all nodes and start a new Scan. If you wish to remove individual entries, then just right-click on a device in the list and select the option to remove it.

5. What does Green highlighted text mean during a Scan?
This means that a Brocade device has been discovered successfully, and will be added to your listbox on the right.

6. What does Yellow highlighted text mean during a Scan?
This means that there was a successful Reply back from a Telnet supported device, but either the authentication failed, or the device was a Standby CP card. It will not be added to your listbox on the right.

7. How do I Telnet to a Brocade device that I have discovered with a Scan?
You can either double-click on the device in the listbox, or select it by clicking on it once and then clicking the 'Telnet' button.

8. How can I access a Brocade device that I have discovered with a Scan, with my Web Browser?
Select a device in the listbox by clicking it once. Then click on the 'Web' button.

9. How do I see more information about a discovered device?
You can either select a device in the listbox by clicking on it once, or you can click on the up/down arrow keys on your keyboard to run through all devices. As each one is highlighted, it will then present you witgh more info on that device on the rest of the screen.

10. How do I stop a running Scan?
You will have to click on the 'Stop/Exit' button at the bottom-left. This will stop the Scan and exit out of the application.

11. How do I change the login authentication settings i.e. Userid and password?
Go to the bottom left and enter in the userid and password settings for both B'series and M'series Brocade devices.

12. I have a slow network. How do I change the length of time to wait for a Reply from a device during a Scan?
Click on the 'Settings...' button and select 'Time to Wait for Reply...'. You will be prompted to select a setting in milliseconds. The default is set to 300ms. Setting this to a higher setting will obviously slow down the amount of time taken to discover devices, but will help in the accuracy of the Scan.

13. I'm not happy with the colour scheme and of the application. How can I change this?
Click on the 'Settings...' button and select 'Colour Preferences...'. Choose the area of the application that you wish to change the colour.

14. I would like a Report of the Discovered Brocade devices. How can I generate a report?
Click on the 'Report' button.  As long as you have devices in your listbox it will then generate a full report of all Brocade devices discovered.  The report will be called 'Report.doc' or 'Report.pdf' (depending on your default reporting application setting under the 'settings menu). The report will be saved to the folder that the application resides.

15. I'm having problems Scanning a Brocade device that I know is on a certain IP address. How can I debug the problem?
You can debug the problem by going to the applications 'settings' folder. Open the 'debug.txt' file and edit this file by setting the value to 'yes' and save it.  Run the Scan on the troublesome device once again. You will then be able to see exactly what is happening. You may report the problem if you wish. Remember to set the 'debug' file back to the setting of 'no' when you are finished.

16. How do I lookup the OUI of a WWN in the name server list?
Select a WWN by highlighting it with your mouse. Then click 'Control-L'. This will display the OUI info for the WWN.

17. How do I capture a Telnet session to a log file?
Start your telnet session to a Brocade device in the listbox. You will be prompted to to choose whether you wish to log the session or not. If you select 'yes', you will then be prompted to supply a name for the file you wish to capture the telnet session to.

18. How do I stop a Scan that I've already started?
Click on the 'Stop Scan' button. You will be warned to wait until the process stops after the IP address it is currently scanning. Just click ok to this message box and wait. You will receive a message in the text box to say that the Scan has been stopped.

19. I am confused. What's the difference between the 'Expect Timeout' and the 'Time to wait for Reply' settings?
The 'Expect Timeout' setting is the time period to wait for an Expected prompt or command used by the Expect program. The default is 10 seconds. Setting this value higher (usually for busy networks) will increase the waiting time, but will be more reliable for the discovery process. Decreasing this value (for non busy networks) will decrease the waiting time, but will be less reliable for the discovery process on busy networks.
The 'Time to Wait for Reply' setting is the initial connectivity response time from a device i.e. the timeout period for a ping reply. The default is 300 milliseconds. Increasing this value for busy networks will provide a more accurate discovery.

20. How do I Rescan the Brocade devices I've already discovered?
Click on the 'Rescan' button. This will then only scan the IP address's from your discovered list.

21. How do I change the size of the telnet window?
In the DanScan program directory double-click on the telnet.exe file. Select properties by clicking on the top-left part of the title bar. You can now change the size and position etc of the telnet window.  Then save the setting by selecting ok and then 'save properties for future windows'.

22. How do I send a single command to multiple Brocade devices?
Tick the Command checkbox at the top of the application. This will enable the Command entry box, and allow you to select multiple Brocade devices from your list by holding the Ctrl key and selecting the devices with a click of the mouse.  Then, in the Command entry box, enter a command or, if you wish to enter multiple commands then separate them with a semi-colon e.g. switchshow;fanshow;psshow.  Once your commands have been entered, simply hit the enter key and the application will login to each device and issue the commands.

23. How can I Save my Multiple Commands to a Script file for later use?
