Noob question about swicthing port on a router

I am trying to understanding vlan on switch and router with packet tracer 6.
I thought switching port on a router will act as it does on a switch (mine are 2960).
I use a router with 1 WAN port and 4 switching port to emulate my cisco 881 (without wireless). Everything was working good with my 5 switches and 4-5 VLAN..then doing a ping test between VLAN.. I discovered that PC belonging to differents vlan can ping each other on a router - switching port...then i remake a basic scenario and post it here. i probably missed a basis of vlan.
FA 0/0 (the WAN port) is not connected.
FA 0/0/0 are port switching on the rooter.
According to my image...why pc0 is able to ping pc1 as there is not a specific route between them on the rooter...May be it is the C on the left side meanig connected..thought we need a static route to make one network communicate with another if they are not on the same network.

The actual ports you connect the PCs to are L2 ports only ie they are not L3 so they cannot route. But you have also configured L3 SVIs (Switched Virtual Interfaces) on your router and it those that are doing the routing.
An SVI is a virtual L3 interface. So from your configuration where you do a "sh ip int" you can see at the bottom
vlan 10 192.168.0.1/24
vlan 99 192.168.99.1/24
those are your SVIs. If you also look at your routing table it shows entries for both your subnets as directly connected routes with those SVIs as well.
If you do a "sh run" you should see in your configuration something like this -
int vlan 10
ip address 192.168.0.1 255.255.255.0
int vlan 99
ip address 192.168.99.1 255.255.255.0
SVIs are generally seen on L3 switches and as as i say there are not configured on the actual port. The idea is a switch could have say 24 ports in vlan 10 and 24 ports in vlan 11 and then you simply configure SVIs for both vlans and now clients in each vlan can communicate with each other.
So to be precise SVIs are virtual L3 interfaces for a L2 vlan. They act much like physical L3 ports eg fa0/0 from your example ie. you can apply acls etc. to them but they do have differences.
Hope that makes sense.
Edit - to confirm all of the above you can simply remove or shut down one of the SVIs and the PCs should no longer be able to communicate.

A question about opening ports

I have a question about opening ports with the airport. I need to open up ports UDP 88 & 3074 and port TCP 3074. I am wondering if I should open these ports for the specific IP address on my network that will be using them or if I should open the ports on the gateway IP (10.0.1.1) not sure which is the right route to take. Any help would be appreciated.
These are for running an xbox over xbox live.

Typically, you will want to open these ports for the device on your local network that needs to be accessed from the Internet. In this case, it would be your Xbox 360.
Unfortunately, the AirPorts are not listed as Xbox Live-compatible routers ... so there is no guarantee doing this will get Open NAT status for Xbox Live.
The following web blog does a great job explaining the NAT issues with Xbox Live. Basically what it comes down to is that although you can get an Internet connection for the Xbox 360 with the AirPorts, you may not get the necessary NAT setting (Moderate or Open) for the Xbox Live game that you want to play. As such, Port mapping may be required to allow Xbox Live access.
The following ports must be available for Xbox Live to operate correctly:
• UDP 88
• UDP 3074
• TCP 3074
To setup port mapping on an 802.11n AirPort Extreme Base Station (AEBSn), either connect to the AEBSn's wireless network or temporarily connect directly, using an Ethernet cable, to one of the LAN port of the AEBSn, and then use the AirPort Utility, in Manual Setup, to make these settings:
1. Reserve a DHCP-provided IP address for the Xbox 360.
Internet > DHCP tab
o On the DHCP tab, click the "+" (Add) button to enter DHCP Reservations.
o Description: <enter the desired description of the host device>
o Reserve address by: MAC Address
o Click Continue.
o MAC Address: <enter the MAC hardware address of the Xbox>
o IPv4 Address: <enter the desired IP address>
o Click Done.
2. Setup Port Mapping on the AEBSn.
Advanced > Port Mapping tab
o Click the "+" (Add) button
o Service: <choose the appropriate service from the Service pop-up menu>
o Public UDP Port(s): 88, 3074
o Public TCP Port(s): 3074
o Private IP Address: <enter the DHCP Reserved IP address for the Xbox you created earlier>
o Private UDP Port(s): 88, 3074
o Private TCP Port(s): 3074
o Click "Continue"

2 noob questions about speaker settin

. What if I don't sync the Creative speaker settings with windows control panel speaker settings?
2. What if I the speaker settings(both Creative and windows) don't match my speaker type?For example, I have only headphone connected to my Audigy 2 ZS but I set the speaker setting to 5. or whatever else. Will this improve my sound quality in games such as Battlefield 2? Am I?supposed to get the virtual 5. surround sound effect? Because I've heard that cmss upmixes stereo sound in?games to virtual 5. or 7. surround sound for headphones.
Thanks.

Re: 2 noob questions about speaker settings?slightlys I have a slightly different set up.
I have 5. speakers that I use for movies and some games. For BF242 I use headphones because they give you an advantage as you can hear people creeping up behind. The virtual surround sound is really good with my XFi xtremeMusic.
First I don't think it matters what you select under Windows Control Panel as the Creative Console Launcher updates speaker settings in Windows. Second if you want virtual 3d with CMSS on headphones just select headphones and enable CMSS3D. Then click the 'headphone' button on the CMSS3D tab and you can test the sound - a helicopter pans around in 360 degrees.
Then in games set the software to output 5. - AFAIK. Battlefield seems to do this automatically but I can't speak for other games. I'm assuming the Audigy has the same CMSS3D tech that the XFi has.

Noob question about launching apps

Greetings all,
Just made the switch to a Powerbook with OS X Tiger, and have a question about launching applications; specifically how to do so without using the mouse. On my Linux boxes (one at home, one at work), I do most of my work from the keyboard, without resorting to the mouse, even in Gnome or KDE.
In Tiger, I can select applications on the desktop, but haven't been able to figure out how to launch them without "clicking"... I've Googled and searched these forums, but no luck so far. Under Linux, it's the Enter key. I assume in Tiger it's some key combination...
I know there's probably a simple answer, but I've not been able to happen upon the appropriate key combo it at random, so I thought I'd ask the experts.
Be gentle, I've only had my PB a week!

To help you in your quest to keep your hands on the keyboard you should check out apps like LaunchBar and Quick Silver. Your hands will never (well... rarely) leave the keyboard again.

Noob question about router IP on SDM Worksheet...

The SDM Worksheet says,
L6A
Router IP Address
Copy the subnet in field L1A to field L6A.
If L1A has subnet field of 192.168.10.0, then these instructions make the router address 192.168.10.0.
I thought the first IP on the subnet was the default IP for the router, eg 192.168.0.1

Chris
I am as baffled as you are looking at the link you provided. If you used the example they give then all interface IPs would end up being the subnet address which is clearly wrong and more importantly would not work.
In terms of the addressing to use it is common to allocate static IPs from the start of the subnet as you say, athough this is just convention ie. any IP from the subnet could be used.
So unless we are both missing something obvious i would just ignore what the sheet is saying and do as you suggest in terms of allocation.

Question about opening ports

Hi All,
I've recently had some problems trying to video chat with a new person. They're on a pc using AIM 5.9. I've been able to chat with a different pc user before as well as some ichat users. I can also successfully connect to the Apple test severs. I've never done any port forwarding/triggering on my router (Netgear wgt624v3). I know that just about every thread here having to do with connection problems talks about opening up a bunch of ports. So my question is should I have to do that if I'm able to connect to the Apple servers, a different pc user and other ichat users without having done anything to my router?
Thanks,
Chris

Hi Chris,
If you can call out to many people and have one that you can not contact there are twoi possibilities.
1) They have not set up their end.
2) You and they are set up but are having problems with the way the other device does NAT.

Question about Time Capsule as primary router

Hi everyone. I'm ready to upgrade my backup drive to take advantage of Leopard's Time Machine. I'm trying to decide between a simple 500 GB firewire drive or spending the extra for the Time Capsule. I have and intel iMac and an older 12 inch powerbook so I understand the advantages of wirelessly backing up my info.
My question is this - in reading reviews, its suggested that I use Time Capsule as the primary router. However, I had AT&T install U-Verse cable and DSL in my house a few months back and it works flawlessly. I'm using the 2Wire AT&T Uverse modem/router as my router. Can I easily make the Time Capsule my primary router without disrupting what is currently a very good network and is it a simple adjustment? Also, if I opt to make Time Capsule part of the network and use my current AT&T router as the primary, will I notice a significant slowdown as some reviews have suggested.
Any help would be appreciated.
thanks
Kory

Depends if you want the fast transfer speed of files. The wireless TC file transfer will be about 8M/sec and ethernet about 15M/sec
Firewire 400 will be about 25M/sec and so will USB2.

Question about IO Ports on A2109 IdeaPad

Hello Everyone:
In a couple of months I'm going to be getting a IdeaPad A2109 Tablet.
I couldn't find manuals for it on Lenovo's site so I came here and found the links that I needed Thanks to those forum poster{s}.
I ran accross in those links the maintance manual and was excited because I couldn't find anything about any of the connections on the tablet.
And any pictures that Lenovo had on their site while good in general didn't in anyway help really in identifying any of the ports.
I tried to the best of my ability to figure them out, But in any event I digrise...
I seen in the manual that it said the Micro usb port was used for Sync to your computer and charging.
OK I figured I can hook my Mini usb Keyboard to that with NP because I already had found out that you could also cahrge the tablet off your computer using one of it's usb ports.
And it also said it has a DC JACK?
Which I took as ity having a seperate connection for normal powering from the cahrging of the Micro usb port.
But yet the diagram gives No Indication of a seperate DC Jack?
My question is this does the IdeaPad A2109 have a Seperate place to plug in your "NORMAL POWER CORD"???
Or is the Micro usb port used for the "NORMAL POWERING" of the Tablet as well???
I really hope that the DC Jack is seperate from the Micro usb port so that I can still hook the odd thing to it while still being hooked to AC....
If not could anyone tell me how I could use it for both at the sametime?
Also let me take the chance to Thank the poster that answered a thread about where the Micro SD Card went, or I would've been pulling my hair out trying to find it...
I take it that the Max Size SD Card is 32gb?
Sorry for all the questions just trying to know all that I can before I buy my new Tablet.
Solved!
Go to Solution.

Some angled adapters will block the HDMI port. This is not a problem for most things but if you plan on keeping your device plugged into power, keyboard etc.... You will not be able to access the mini HDMI.

Satellite P850 - question about Infrared port

Hi,
I have Windows 8 Pro installed onto my laptop and I've downloaded all the drivers and everything is working fine apart from the Infrared. I've searched all over the internet and I can't find a remote control to use with this laptop (including the Toshiba website).
I've installed the latest ENE CIR Driver (v4.1) as well as the Toshiba Remote Control Manager (v3.1.0.1). I looked in Program Files to open the Toshiba Remote Control Manager however when I click on the program to open it... Nothing happens (including in the notification area).
So my question is can I actually get a remote working with this laptop at all and if not then what is this Infrared port for because I can't find anything on my computer to actually use it with/for?!
Thanks for your help :p

Hi
Some Satellite P850 models are equipped with the remote controller and its possible to use the remote controller with Windows Media Center to play discs or videos, to view pictures and to watch recorded TV programs.
Models which dont include the a remote controller are *NOT* equipped with the an infrared receiver so the notebook cannot be operated with a remote controller.
The remote controller was not part of the package so your notebook does not support infrared receiver and therefore the installation of ENE CIR Driver and Toshiba Remote Control Manager was useless

Noob question about trying to duplicate rows in a table

Simplification of problem is I've got a table with user_id, name, year where user_id is pk. I would like to take all the rows that match year=2008 and insert them into the same table, but start the user_id at a certain number and set year=2009.
I know this doesn't work, but it's what I want to do in noob-code:
INSERT into TABLE (
user_id, name, year
) VALUES (
SELECT user_id_seq.nextval after starting at 3500, name, 2009 from same table doing insert to where year = 2008
I've contemplated using a temporary table, I've also seen mention of cursors, but don't quite understand what they are. I'm really, really new to Oracle and SQL in general, but am familiar with programming and shell scripts. I know more in depth searching might land me what I want, but I think my search syntax would be just as weak as my knowledge of the material. I'm just thinking this is something so basic and easy that my searches aren't using the right terms to catch a hit.

Hi,
Welcome to the forum!
You can INSERT all the results of a query by substituting the query where you otherwise would have "VALUES (list)".
For example:
INSERT into TABLE_X
       (user_id,              name, year)
SELECT user_id_seq.NEXTVAL, name, 2009
FROM    table_x
WHERE   year = 2008;This assumes that the sequence user_id_seq exists and is ready to issue the correct value. (It's unclear if that's part of the problem.)
Temporary tables and cursors (which are a way of getting query results in PL/SQL) are only useful for inserting in rare situations, where you have to do very odd, convoluted things. Think (at least) twice about how to do what you need to in SQL, and if you can't think of a way, then ask.
Yes, basic things often are hard to search for, especially if you don't know the right terms.
There are several good teach-yourself SQL books that explain this kind of thing. Getting one would be a good investment.
[All the Oracle manuals|http://www.oracle.com/pls/db111/portal.all_books] are on line. There's an example of this in the SQL Reference manual, under THE INSERT command.
Edited by: Frank Kulash on Nov 26, 2008 12:59 PM
Clarified usefulness of cursors. They have a lot of good, common functions, but helping with INSERTs is not one of them.

Noob question about Airport

I have one of the early G5 PowerMacs (single 1.6 gHz). It currently doesn't have an Airport card, but I'd like to install one or an equivalent. Here's my two questions:
1.) Are all G5s compatible with Airport Extreme cards?
2.) Are there good third party alternatives out there?
I wish Apple would be clearer about what systems are "Airport Extreme Ready".
Thanks in advance!

Noob question about HDR images

hi everybody! i am reading this book about photoshop hoping to understand a lot more than i already know about pixels and colors and image dinamics and such..i got to the chapter about HDR images and here's what i dont get. as i understand, given a HDR image it has 32 bit depth meaning its file contains much more information about contrast and brightness than any existing monitor can output, so when u open it in photoshop u will never see its true quality. my question is( and i admit it may seem pointless to some, but i am committed to understand the cause and purpose), when converting it to 8 or 16 bit depth this window pops up asking me to tweak gamma, exposure, shadows and highlights, etc., but why is this linked to the conversion process? why not simply convert it, maintain the same appearance as before and then if needed manually adjust using all the image controls from the photoshop menus? i have CS6, if that matters.

I don't know if this will help, but I've heard about HDR monitors (still very expensive), which supposedly very accurately display the HDR values. If you hang one on the wall in your house, people might think it's a window, since it is literally a source of light, in the same way a window to the outside world is.
Possibly the most surprising use of HDR imagery is in 3D apps where global illumination models are used. HDR imagery literally is the only source of light for these images. There are no lights in the scene, only HDR imagery. This is because of the great dynamic range of HDR.
A more practical (to me) use of HDR is when resurrecting antique images. If you scan multiple exposures from old prints, then create HDR, sculpting values in 16-bit becomes a very powerful tool, only due to the HDR value range.
Photoshop, although it can edit very well in 16-bit, can only show 8-bit representations of HDR imagery, since almost all monitors are 8-bits per channel. Because of the monitors, we can only see a small part of what is actually present in the HDR file.
I've never done it, but I imagine that if we all had HDR monitors, we'd need to wear protective glasses (like you wear driving in your car when the sun is out) most of the time to do our work. :+)

Question about a light on my router

So there is an orange light on the front of my router! I was wondering what this meant.. It wasn't lit up before today. About 30 minutes ago I upgraded my firmware. Is the orange light a bad thing? The light is to the left of the power light and it has a symbol on it!

No Orange Light is not a Bad Thing ... it is lit up due to WPA security on the router ...

A noob question about precedence...

Ok, here's the question.
let's say:
int a=0;
a=a++;
when a is evaluated, 0 is returned.
isn's that expression like this?
a=a=0;
a=a+1;
apparently I'm wrong.
so if i forced a parentheses on it
a=(a++);
but again, a is evaluated as 0,
I know how ++a would work, but i'm really curious about the suffix one.
can any one explain to me?

i mean how no matter what u do to
a=a++
i know in this case that a is evaluated first b4 it is added to 1,
but it's gona add that 1 eventually right? so the evaluation of
a in the en should be 1.
Ah, I'm so confused, help

Noob question about DIV tags

Learning DW and CSS so patience is in order .
I've being reading numerous posts here and on the web about avoiding tables for laying out web pages. I can see the advantages in terms of cleaner codes and easiness of updating and changing sites at a later time. So I started learning about DIV tags (although tables is very easy for me) and have practice a few times with fairly good results, love the absolute positioning with it. Having said that, for the love of me, can't find a way of centering horizontally a page designed with DIV tags (due to ignorance), for example, 1 column/three rows page, after defining styles, size and colors I enclosed everything in another DIV tag, wrapper I think is called, but have not found a way of centering it on the page, text-aligment on the DIV tag only centers the text not the DIV itself, how to go about this? Help is appreciated.

love the absolute positioning with it.
Get over it. It's a trojan horse. Absolute positioning is not a general layout method.
To center ANY block (non-absolutely positioned) element, use CSS to give it a width and left/right margins of 'auto'. For example -
<div id="foo">...</div>
That div will be centered with this CSS -
#foo { width:300px; margin:0 auto; }
I think you are on the wrong path already, though. Stick with tables (which you say are very easy for you) UNTIL you a) understand CSS well enough to understand what absolute positioning is and why I say it's bad, and b) understand how to use float, margin, and padding to place things on the page. Then you are ready to move away from tables.
