VLANing using 3500xl switches

Currently we have two separate LAN infrastructures each using only VLAN 1. Each LAN has a unique IP address subnet.
This is a campus environment. There is now a need to connect a small building on the campus that will have a few devices on one LAN and a few other devices on the other LAN. The company doesn't want to buy 2 switches. We have a 3524 switch with two fiber connections and we have enough fiber pairs so that we can use one fiber connection for each LAN. Each of the fiber connections would terminate into another 3500 switch in each LAN.
Is there a way I can define two VLANs on the switch in the small building, yet have the traffic for each LAN go over it's own fiber link to the appropriate LAN and be handed off as being part of VLAN 1 so that I don't have to define a new VLAN on a number of existing switches? Could the feature to configure the native VLAN for untagged traffic be used?

Hello,
if you cannot create a new VLAN and need to use the existing VLAN 1 from both locations, there would be a (rather tedious) approach to this: add static MAC address entries on the switches connecting to your 3524. Let's say you have the following setup, including the 3524 switch:
Lan1(3500_1) --> Fiber Link --> 3524 --> Fiber Link --> Lan2 (3500_2)
On switch 3500_1, you would add static MAC entries for the devices from Lan2 like this:
mac-address-table static 0020.1223.e3f4 interface GigabitEthernet0/2
Interface GigabitEthernet0/2 would be an unused interface, and by statically directing the MAC addresses from the other VLAN to that unused port, you effectively deny access for these MAC addresses. Do the same for the MAC addresses from Lan1 on switch 3500_2.
I am not sure if this is going to work as desired, but you might want to give it a try...
Regards,
GP

HELP -menu using a switch statement

Hello to all. I'm new to the Java world, but currently taking my first Java class online. Not sure if this is the right place, but I need some help. In short I need to write a program that gives the user a menu to chose from using a switch statement. The switch statement should include a while statement so the user can make more than one selection on the menu and provide an option to exit the program.
With in the program I am to give an output of all counting numbers (6 numbers per line).
Can anyone help me with this?? If I'm not asking the right question please let me know or point me in the direction that can help me out.
Thanks in advance.
Here is what I have so far:
import java.util.*;
public class DoWhileDemo
     public static void main(String[] args)
          int count, number;
          System.out.println("Enter a number");
          Scanner keyboard = new Scanner (System.in);
          number = keyboard.nextInt();
          count = number;
          do
               System.out.print(count +",");
               count++;
          }while (count <= 32);
          System.out.println();
          System.out.println("Buckle my shoe.");
}

Thanks for the reply. I will tk a look at the link that was provided. However, I have started working on the problem, but can't get the 6 numbers per line. I am trying to figure out the problem in parts. Right now I'm working on the numbers, then the menu, and so on.
Should I tk this approach or another?
Again, thanks for the reply.

Using a Switch statement for Infix to Prefix Expressions

I am stuck on the numeric and operator portion of the switch statement...I have the problem also figured out in an if/else if statement and it works fine, but the requirements were for the following algorithm:
while not end of expression
switch next token of expression
case space:
case left parenthesis:
skip it
case numeric:
push the string onto the stack of operands
case operator:
push the operator onto the stack of operators
case right parenthesis:
pop two operands from operand stack
pop one operator from operator stack
form a string onto operand stack
push the string onto operand stack
pop the final result off the operand stack
I know that typically case/switch statement's can only be done via char and int's. As I said I am stuck and hoping to get some pointers. This is for a homework assignment but I am really hoping for a few pointers. I am using a linked stack class as that was also the requirements. Here is the code that I have:

You're welcome.
Going back to your original post:
5) Tried running Itunes in 'safe mode', running itunes as an administrator..nothing.
Was that iTunes' safe mode as opposed to Windows' safe mode? iTunes safe mode is invoked by holding down CTRL+SHIFT immediately after clicking the icon to launch iTunes and continuing to hold until this message pops up:
Click continue, then close iTunes and reopen. With luck iTunes now opens normally every time.

Using multiple lines of query in sqlcmd using -q switch

Hello
I am trying to use sqlcmd to run a set of sql statements. If I use -i switch and input a file with sql statements, it is working fine, but I am trying to use the sql statements using -q to avoid the creation of the input file. But I am not having luck with
-q, can someone let me know if putting multiple lines of code is possible in -q switch like below?
A simple restore command like below. If I use the whole restore command in single line it works fine like below:
sqlcmd -E -S servername -d master -Q "restore database bestst_test from disk='E:\Backup\test\bestst\bestst_20101222.bak' with move 'BESMgmt415_data' to 'E:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\bestst_test.mdf',move 'BESMgmt415_log'
to 'E:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\bestst_test_log.ldf' "
but if I split the restore command into 3 lines like below, it fails, can someone let me know how to use the multiple line feature in sqlcmd -q switch?
sqlcmd -E -S servername -d master -Q "restore database bestst_test from disk='E:\Backup\test\bestst\bestst_20101222.bak'
with move 'BESMgmt415_data' to 'E:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\bestst_test.mdf',
move 'BESMgmt415_log' to 'E:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\bestst_test_log.ldf' "

Well actually there is a way, in command prompt you can you the carat character (^) to indicate that there is more lines. So in your restore case:
sqlcmd -E -S servername -d master -Q ^
"restore database bestst_test from disk='E:\Backup\test\bestst\bestst_20101222.bak' ^
with move 'BESMgmt415_data' to 'E:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\bestst_test.mdf', ^
move 'BESMgmt415_log' to 'E:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\bestst_test_log.ldf' "
I must say, it is abit of a hassle (since there are several restrictions to how you need to break the line), and you actually better off using the input file for this.
Thank you

My ipad 2 won't rotate. i tried reseting it severally my "Use Side Switch" is set to Mute and there is no rotation lock sign close to the battery sign in the upper right side

my ipad 2 won't rotate. i tried reseting it severally my "Use Side Switch" is set to Mute and there is no rotation lock sign close to the battery sign in the upper right side

The software switch is in the task bar at the bottom. Double tap the home button and swipe to the right in the bottom of the screen. The speaker icon on the left would be where the software switch would be.
If you don't see a lock icon in the upper right corner, the screen isn't locked, reboot your iPad.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

These are usually the features of a faulty battery. Restore iPhone Firmware with iTunes 10.7 or 11 on computer. See if better. If not, and there is Warranty or AppleCare make Genius reservation and take iPhone to Apple for resolution. If no Coverage, still make Genius reservation and take iPhone to Apple Store for free quick (minutes time) battery diagnostic testing.

Connecting 300 IP Cameras using Cisco Switches

Require help on a Case study. (Can only use Cisco switch)
Description:
This is a setup required for 300 security cameras.
So availability and redundancy is important.
I have calculate the bandwidth using [URL="http://www.jvsg.com/download/IPDesignToolSetup.zip"]this software[/URL].
If each camera is set to 5MP and H.264-10, Bandwidth is 12.08Mbit
So 300 cameras will require at least 3624.96Mbits in total.
(correct me if i am wrong)
Each NVR has 32 port.
It will be just connecting within a LAN.
Here is the brief 2 possible design I have draft out, but I am not sure which model and series of cisco switch to be use??
Design 1:
Design 2:
Please advise which model and series can be used for this 2 two of design.

Hello Chun,
you need to accomodate 300 cameras and 32 ports for each network video recorder.
data flows are from cameras to network video recorder ports.
The amount of traffic per port at port connected to cameras is not huge and total traffic from cameras exceed GE links
48 * 12,08 = ?? in any case less then < 1 Gbps
You can deploy a hierarchical network design with an access layer made of switches with fixed configuration 48 ports and GE uplinks like a C3750 with 48 ports or a 2960 with 48 ports (if it exists)
Each access layer switch needs to have two uplinks to distribution switches
And you need 300/48 switches => 7 switches => 7 GE uplinks on each distribution switches
Distribution switches should be two and should be able to connect to access layer switches and to NVR that requires 32 ports each.
Different solutions are possible:
instead od deploying 7 standalone switches with 48 ports each you could use two modular C4507 equipped with WS-4548 48 10/100/1000 linecards
the distribution switches can be two C3750 E, eventually configured and connected as a stack, to allow to use both uplinks of each access layer switch
Hope to help
Giuseppe

Ipad2 does not change orientation. I have not used the switch for lock rotation it is used for mute

Ipad2 does not change orientation. I have not used the switch for lock rotation it is used for mute

Is there a lock symbol at the top of the screen next to the battery indicator ? If so, and as you've got the switch set to notification mute, then have you checked the taskbar (the function that the switch isn't set to is controlled via the taskbar instead) : double-click the home button, slide the taskbar to the right, and it's the icon far left.
If you havn't got the lock symbol at the top then try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Unable To Use Device Switch Wizard

Hello,
I just bought a new Tour and want to migrate my data from my Palm Centro to the Blackberry. I have tried using a PC with Vista x64, Vista x32 and XP Pro. For whatever reason, the program doesn't see Palm Desktop or the Centro. Anyone have any ideas?
MIke

Hi and Welcome to the Forums!
I seem to recall others reporting something similar...see this KB:
KB05459 How to use the Switch Device Wizard to switch from another smartphone to a BlackBerry smartphone
Unfortunately, the Centro is not listed. But, all may not be lost...see these KB's:
KB10722 BlackBerry Desktop Manager does not detect the Palm software when using the Switch Device Wizard
KB04437 How to use the organizer data migration wizard
KB04346 Field mapping list for the PIM Data Migration Wizard
And, if all else fails, you can attempt to use your Palm software to export to ASCII or CSV, and then import that via the RIM software:
KB04312 Create and synchronize with an ASCII export file
Good luck and let us know how it goes!

Suggestions on DHCP using cascading switches

Is there any reason you can't create a different vlan and create a new scope for that vlan on your current dhcp server along with helper addresses on your switches? It seems you're over complicating things as of right now.

gents,we like to provide a WLAN Network for guests in our Company which is connected through a different Provider than our internal Network.I connected the incoming hardline to one router - providing WLAN #1 with DHCP.I like to route it to two floors, using the LAN environment.I have only ONE line available to get the Provider to our Switch-rack.My idea is to connectthe LAN-port of WLAN-Router #1 to the Switch rack and attach another WLAN-Routers to the other floors.My question is: what is the best way to provideDHCP ?a) Router#1 is doing DHCP and all connected secondary routers are just passing through.b) every Router is doing DHCP for himselfI once read that there could be Problems using cascading Switches/Routers. Any enlightment here?

Activate bluetooth using Wireless Switch?

I'm getting really frustrated now because my laptop seems to have forgotten that a thing called Bluetooth exists. I noticed the bluetooth wasn't working so I tried to install the newest driver but it fails to install saying I need to "Activate bluetooth using Wireless Switch". As far as I can tell this means pressing fn+f2 which turns on/off the wifi and blutooth but this does nothing and besides that is always on.
Next I went to mobility center and found this: .
Bluetooth appears to be on but I still can't connect anything with it or install the latest driver. When I click launch it takes me to my PC settings in which there is nothing about bluetooth. Search bluetooth yields two results: set up a connection or network and turn on or off wireless devices. Under wireless devices there are only two settings, airplane mode and wi-fi. Under Set up a connection everything is related to LAN and Wi-Fi, nothing about bluetooth.
If I go to services.msc I find this: So bluetooth defintiely exists in some form but for some reason I just can't access it and it can't pick up bluetooth devices. Someone please tell me I'm an idiot and I'm missing something obvious, please I've been at it for an hour.

Hi,
If you still haven't been able to resolve this, have you tried physically removing the card, deleting all the drivers, etc., rebooting the system, and after that shutting down. Then physically reinstall the card, either let Windows find the drivers or install them yourself, and see if it straightens out the issue?
You can also check Microsoft's article on troubleshooting bluetooth issues.
Other than that, honestly I'm not sure what you may have missed. Let me know if you've resolved the issue (and if so, how, so that others with the same problems can find your solution). If not, like I said, physically remove the card and uninstall the drivers to see what happens.
Hope this helps.
