Vlan Select & Layer 2 Multicast optimization

I am going to implement this vlan select feature in my campus network. We are running on 7.3 & planning to move into 7.4 WLC code as well. I use below reference document for this task.
WLC 7.2 VLAN Select and Multicast Optimization Features Deployment Guide
I am bit confuse about layer 2 multicast optimization. Document says we can enable/disable by using below CLI commands. "
config network multicast l2mcast <enable|disable > <interface>"
I have 4 interfaces called student-wireless-1 to 4 (vlan 1161-1164) map into single interface group. For layer 3 multicast I will make vlan 1161 as the multicast interface with "multicast vlan feature" enabled. For layer 2 what should I do ? Is layer 2 multicast enable on all these interfaces by default ? If so should I disable l2 multicast on 3 of these interfaces like below ? Would there be any issue of disabling this layer 2 multicast on those interfaces ?
config network multicast l2mcast disable student-wireless-2
config network multicast l2mcast disable student-wireless-3
config network multicast l2mcast disable student-wireless-4
If it is not enabled by default, shoud I go ahead enable it on one interface like below ?
config network multicast l2mcast enable student-wireless-1
If someone can explain this that would be highly appreciated.

Thanks for the help but I found some further information. Some switches (2955, 2960, 3560 or 3750) can act as a "multicast querier", taking place of a multicast router without actually needing to support multicast routing. This means you dont actually need IP Services IOS or a layer 3 switch.
Configuation as per below;

Supported platforms below (look for igmp querier);

Thanks for putting me on the right track however.

VLAN Select with firewall interfaces

We are looking to implement vlan select on a wireless network. This network needs to be terminated behind the firewall. We were looking at putting the layer 3 interfaces on the core, then using a route-map to change the next hop to the common firewall interface. Is there a better way to configure such a setup?

Yup,
There should be no problem with such configuration. I suspect something is misconfigured on switches. Are you sure both ports are trunks and both are configured as single etherchannel in lacp mode on switches?
Because VLANs are configured over bonds - I'd rather suspect LACP misconfiguration not VLANs here. AFAIK you should be having problems without using VLANs too.
Here is my config which just works and there are couple vlans configured over bond0:

Could not complete the new 3D extrusion from selected layer command because the path is too complex.

I was trying to do a photo of mine like in this video but its not working help needed. thanks.
http://www.youtube.com/watch?v=egyLY78H7nE
When I tried the 3D I got an error message that said (could not complete the new 3D extrusion from selected layer command because the path is too complex.) what does this mean and how can i fix it?

There was a bug at one time where really simple paths (like a triangle, for example) could cause that error.
Is your path really simple (I don't plan to go watch the video)? If so, have you installed the latest update for Photoshop? That bug may have been fixed already.
If it's not that, it's possible that if your path is really complex and simply exceeding Photoshop's capability.

WLC 5508, vlan select, reserved address in external DHCP server

Hi guys,
I have a deploy with a WLC 5508 version 7.0.116.0, APs mode local and vlan select feature enable. The issue is that the reserved IP address in external DHCP server not work. The DHCP contains a reserved IP address associates with mac address, but the assignement of IP is not match with de policies in DHCP. All others services operate normally.
This reserved assignment operate previusly to modificate the WLAN to vlan select feature. Help me to improve this situation.
Thanks.-
Best regards

Hello Abhishek, thanks for you quick answer....
the link was a document used for the deploy, but not especifict nothing about the reserved IP address for particular host. In other words, the reserved IP address (through MAC address) in external DHCP server not work when "vlan select" its enable.

Problem with "Create New Extrusion from Selected Layer" CC 2014

Hello, I'm experienced with Photoshop but am new to 3D text in Photoshop. I type in some text and convert to a shape. When I choose Create New Extrusion from Selected Layer I get dialog box I don't see in any tutorials. It says "You are about to create a 3D layer. Would you like to switch to the 3D workspace? Yes/No, Don't show again." Which should I use for 3D text?
If I choose Yes, all the panels go away and the content in the tool options bar (ribbon?) just under the menu bar go away. I have to restart Photoshop to get the tool options back. What could I be doing wrong?
Thanks - Dave

I just chose "No" and didn't look back. I like my workspace just as it is, and don't prefer Photoshop to change it for me under this particular case.
You can make the 3D panel visible yourself via Window - 3D. I find it's a good alternate for the Actions panel, as I don't have any actions at the moment that work in the 3D world.
The panels you'll want to see easily if you work on 3D are the 3D panel and the Properties panel, among a few others.
Regarding getting your workspace back the way you like it... Note the little selector near the upper-right corner of the Photoshop main window. That can be used to select a workspace. I suggest you experiment and get familiar with the concept of workspaces. You can define your own and save it with a name, and that truly can be helpful.

How to save a slice of selected layer or selected object

I am new to Fireworks CS3. I have a layered PSD and want to
create slices (or images to be used separately on a web page via
Dreamweaver) from certain selected layers or certain objects
showing the selected layer and / or object only. I tried and got a
slice that contains all visible layers cropped to the size of the
object I wanted. Can someone point me to a resource that will show
me some tutes or offer an explanation?
For example, suppose I have an apple as a background image on
a bottom layer, with other images on other layers overlapping the
apple in my psd file. How do I create a slice of just the apple?
And, suppose I have an apple, an orange and a banana on the
same layer, but I want to create a slice of each fruit
individually. How is this best done?
Thanks.

Select layer/object will not move in PS, but will move another layer. Need help

I appreciate the help ahead. I cannot figure this out with my Photoshop CC.
Basically when I select a layer on the right, and then go to move the object in that layer, it moves a different layer behind it.
In the screen shot below on the left I am selecting the artwork layer on the right, which is the flip flops on the shirt.
From here I can use the arrows to move the graphic. However, as soon as I use the mouse to select the flip flop graphic and go to move it, the layer selection on the right jumps to the shading and moves a background layer.
What am I doing wrong? Super frustrating!
Running Win 7 x64 8 gig ram, i7, 2 gb Nvidia card.
Thanks!

You probably have Auto Select Layer on. (Options bar)

How to get Command key to enable/disable only "Automatically select layer..." functionality

Hi everyone,
With no updates or preference changes that I know of, PS started working differently for me today. With the Move tool I normally have "Automatically select layer..." option on. I can then select sub-groups in my Layers palette, hold the Command button to temporarily toggle "Automatically select layer..." off, and drag that sub-group around the canvas.
Today when I toggle the "Automatically select layer..." button on, holding Command temporarily toggles it off.
But when I toggle the "Automatically select layer..." button off, holding Command changes the "Layer/Group" option next to it.
Does anyone know why this just started happening or how I can change it back and allow the Command button to temporarily keep sub-groups selected?
Here's a quick video showing the issue: auto select.mov

Looks like this is aggravating a ton of people.
See a more complete thread here: Re: PS CC 2014 Move Tool Bug?
And the feedback here, with an update from Adobe saying "we're working on it": Photoshop: Move Tool - Toggle auto select shortcut changed

Moving selected layer in PS3

Hi all!
In a new CS5 I didn't meet this problem, but since I have to work on CS3 (Windows) for a while, I'd like to ask for help.
When I select a layer in a layer panel and then I want to move it with a move tool, in my earlier experience the selected layer in panel was moved, despite the point from which I start to drag. Now, if I select layer1, but start to drag in a window when pressing on layer0 (it's too hard to pick slim lines of layer1), it "forgets" that I selected layer1 and drags layer0. Any ideas where I could cgange this option?
I coudn't find any auto-select options in PS so far..
Thanks!

Sounds like you may have the "Auto-Select" option set.
With the Move Tool active, look for this checkbox in the options area at the top of the Photoshop main window, and uncheck it:

I need to create an action or script to save the file with the name of the selected layer

I need to create an action or script to save the file with the name of the selected layer (not including the hidden layers, but including those visible).
How could modify the script: 'Layer Comps To Files.jsx' to get the result?
Warning: I do not need to export all layers as files.
Who can help me?
THX in advance

Versione in Italiano (Further down the English version)
NB - Nella versione inglese ho messo tutte le immagini dei menu in italiano.
Versione per Mac, ma credo sia identico per Windows.
Spiego passo passo cosa ho fatto:
- Ho creato un file esempio con tre Livelli, salvato sulla scrivania e ho chiuso il file.
- Ho aperto il file e selezionato il Livello al centro per iniziare a registrare una azione che ho chiamato: Save with Name of Selected Layer
- Nuova azione
- Dare il nome e premere Registra
Ora salva…
- Menu --> Livello --> Nuovo --> Livello... e premi -ok-, (lascia il nome che viene mostrato)
- Ancora una volta Menu --> Livello... --> Nuovo --> Livello... e premi -ok-, (lascia il nome che viene mostrato)
- Menu --> Livello --> Ordina --> Dietro
- Menu --> Livello --> Unisci sotto
- Menu --> Livello --> Unisci visibili
- Menu --> Livello --> Nuovo --> Livello... e premi -ok-, (lascia il nome che viene mostrato)
- Menu --> Livello - Nascondi Livello
- Menu --> Elimina --> Elimina livelli nascosti (press -Yes-)
- Menu --> Livello --> Nuovo --> Livello... Inserisci questo: 'Move this to the trash' e premi ok
- Menu --> File --> Script --> Esporta Livelli in File... (Nella finestra che si apre scegliere l’opzione che si desidera, ma togliere il prefisso del nome) e premere -Esegui-
- Selezionare il pannello Storia cliccare su Elimina premendo -Si- ogni volta che si apre la finestra di dialogo (Ripetere 8 volte questa operazione sino ad arrivare nella storia alla condizione di partenza. Ho visto che è meglio di Ripristina -F12-)
- Fermare la registrazione.
A questo punto, mandando in esecuzione questa Azione, ho raggiunto parzialmente l’obiettivo perché i file così creati mantengono, purtroppo, dei prefissi numerici per evitare probabilmente la sovrascrizione di file (credo senza avviso) nel posto dove vengono creati.
Per ottenere l’obiettivo occorre un nuovo passo ed a proposito di questo riferisco quanto segue:
ATTENZIONE - L’operazione descritta qui di seguito deve essere fatta su di una copia del file, per cui:
- Duplicare il file,
- Spostare l’originale in altra cartella
- Lavorare sul file duplicato.
mi riferisco a questo...
ATTENZIONE - Questa modifica è effettuata a proprio rischio e pericolo ed il sottoscritto non si assume alcuna responsabilità su quanto venga fatto soprattutto da mani inesperte.
ATTENZIONE - Questa modifica sovrascrive qualsiasi file che abbia nome uguale al layer che viene selezionato più l’estensione del file naturalmente.
Comunque la modifica è banalissima e a portata di chiunque.
Procedere così:
- Chiudere Photoshop
- Aprire (nel percorso specificato dall’immagine) il file “Export Layers to Files.jsx” (Export Layers To Files.jsx 1.0.0.16) con un editor di testo puro.
- cercare la stringa (dovrebbe essere in riga 1029)
var fileNameBody = fileNamePrefix;
fileNameBody += "_" + zeroSuppress(i, 4);
fileNameBody += "_" + layerName;
- sostituirla con:
var fileNameBody = fileNamePrefix;
fileNameBody += layerName;
- cercare la stringa (dovrebbe essere in riga 1047-46)
var fileNameBody = fileNamePrefix;
fileNameBody += "_" + zeroSuppress(i, 4) + "s";
- sostituirla con:
var fileNameBody = fileNamePrefix;
fileNameBody += "";
- salvare e uscire.
- riavviare Photoshop
- provare l’azione registrata facendo attenzione che il nome del layer non sia identico al nome di un file già presente altrimenti questo verrà sovrascritto.
Domanda:
Perché ho creato livelli che poi ho eliminato ecc.
Risposta:
Semplice per evitare errori di esecuzione delle azioni nel caso di operazioni con livelli mancanti o altro.
Semplice... no?
English version
Mac version, but I think it's the same for Windows.
First of all, I'm translating the actions that I made using the Italian version of Photoshop, you look at the position of the menu that I have chosen to do the work with other languages.
I explain step by step what I did:
- I created a sample file with three layers, saved to the desktop and I closed the file.
- I opened the file and select the layer at the center to start recording an action that I called: Save with Name of the Selected Layer
- New action
- Give the name and press Save ( I think it is so in English )
Now save ...
- Menu -> Layer - > New —> Layer… and press -ok- , (leave the name that is shown)
- Once again Menu -> Layer - > New —> Layer… and press -ok- , (leave the name that is shown)
- Menu -> Layer - > Arrange (order) -> Behind
- Menu -> Layer - > Merge Down
- Menu -> Layer - > Merge Visible
- Menu -> Layer - > New —> Layer… and press -ok- , (leave the name that is shown)
- Menu -> Layer - Hide Layer
- Menu - > Delete - > Delete hidden layers (press -Yes- )
- Menu -> Layer - > New —> Layer… Enter this: ' Move this to the trash ' and press ok
- Menu -> File - > Scripts -> Export Layers To Files... (In the window that opens select the option you want, but take away the name prefix) and press - Run -
- Select the History panel and click Delete (on menu opened) pressing -Yes- every time when open the dialog box (8 times Repeat this step until you get into the story to the starting condition. Not use Restore -F12-).
- Stop recording.
At this point, by executing this action, I have reached the goal partly because the files created in this way remain, unfortunately, the numerical prefixes to avoid possibly overwriting of files (I think without notice) in the place where they are created.
To achieve the goal we need a new step and thinking about this as follows:
WARNING - The operation described below should be made on a copy of the file, so :
- Duplicate the file
- Move the original folder to another
- Work on the duplicate file.
WARNING - This modification is performed at your own risk and the undersigned assumes no responsibility on what is done mostly by inexperienced hands.
WARNING - This change will overwrite any files with the same name as the selected layer plus the file extension of course.
However, the change is trivial and within reach of anyone.
Proceed as follows:
- Close Photoshop
- Open (in the specified path from the image ) file " Export Layers to Files.jsx " (Export Layers To Files.jsx 1.0.0.16) with a pure text editor.
- Search for the string (should be in line 1029 )
var = fileNameBody fileNamePrefix ;
fileNameBody = + "_" + zeroSuppress (i, 4 ) ;
fileNameBody + = "_ " + layerName ;
- Replace it with :
var = fileNameBody fileNamePrefix ;
fileNameBody + = layerName ;
- Search for the string (should be in line 1047-46 )
var = fileNameBody fileNamePrefix ;
fileNameBody + = "_ " + zeroSuppress (i, 4) + "s" ;
- Replace it with :
var = fileNameBody fileNamePrefix ;
fileNameBody + = "";
- Save and exit.
- Restart Photoshop
- Try the recorded Action, making sure that the layer name is not identical to the name of an existing file otherwise it will be overwritten.
Question:
Why I created levels which I then deleted etc..
Answer:
Simple to avoid errors of execution of the actions in the case of transactions with missing levels and other.
Simple ... is not it?
Sorry for my bad English...
Thanks in advance for any hint.

Requirements for VLAN select feature in 5508 WLC

Hello,
We implemented WLC 5508 software version 7.3, with 8 Aironet devices, most of them are AIR-LAP1131AG-E-K9, and two AIR-LAP1242AG-E-K9.
I could really have benefits of VLAN select feature, but I noticed that it's not working like it should. Two interfaces are in Interface group, but from 45 clients only few of them has IP address from one subnet, others have from second sub.
I see requirements for this to work is 32 MB of flash on LWAP devices..I only have 16 MB..
Is there a way to work this thing out? upgrade of flash on devices or something ?
Thank you in advance and kind regards..
Lovro

Thx L - as usual, I need to read before speaking
Interesting topic though. I would assume that the MAC hashing algorithm used would be similar to how etherchannel maintaines load balancing (src-dst) etc.. What I don't quite understand is the definition of "dirty". What makes an interface "dirty"? Given the flow chart depicted in the link you sent, I'm wondering how the interface assignments are kept in te switch. I'm assuming you create the interfaces, create the interface group, assign the interfaces to the group and finally assign the interface group to the WLAN. During all this time, how are the stations using that WLAN being handled? Almost should clear everything out, create the group tied to the wlan, THEN join the stations one at a time and see what interface they get assigned to. At that point it should be balanced. Also, it's my understanding that those stations should keep their assigned interface the next time they connect unless there is a "dirty" condition which I don't quite understand yet.
Anyway - rambling now. Loking forward to your test results. Thx again! //art

The equivalent of ip multicast boundary in NX-OS is PIM Join/Prune filter:

How can I change the UI colour of a selected layer in PS CS5.5?

Hey,
Just wondering how to change the colour of the selected layer in the layers pallete? It's quite annoying the way it is (Dull grey/blue) and sometimes hard to see what layer's selected?
I prefer the brighter blue on my other computer!
Any tips much appreciated

Oh, i missed that you said cs5 and not cs6?
Message was edited by: R_Kelly
If it's cs5, did you try changing the highlight color in the system preferences either under Appearance or General?

How to get only the selected layer data?

Hi All,
I'm using dissolve sample plugin. I added two layers in photoshop both of different dimensions, say 1000 * 1000 & 2000 * 2000. Now I select the layer with 1000 * 1000 dimension and click on Dissolve plugin. The preview image what is shown in dissolve plugin dialog is not just the selected layer, but also some extra pixels around the selected layer.
Do I need to set any flag for getting only selected layer data to display in preview?
Also I need to get only the selected area in a particular layer. When I checked FilterRecordPtr, haveMask flag is TRUE if the part of the layer is selected. But how do I get only the part of the layer that is selected for displaying preview image?
Please let me know if the description is not clear.
Thanks,
Dheeraj

Thanks Tom Ruark for the response.
That is exactly the same thing what I'm seeing.
1.Is there a direct way to know the bounds of the layer without the transparency grid so that I can show only the layer?
2. If I select an area of 50*50 within a layer(1000*1000) using Rectangular Marquee tool, then I want only that selected area to be shown in preview. For this there is a haveMask flag which indicates whether or not there is selection, but the selected bounds are not available. I'm currently calculating the bounds. I just wanted to know if Photoshop SDK has any field for getting the bounds?

(Layers Palette) When selected, layer is highlighted in grey, not blue.

When I select a layer, it is highlighted in grey (in the layers palette) and I am unable to edit it. My current process for making a layer editable is as follows:
Select layer (highlighted in grey)
Double click layer (opens "Layer Styles" dialogue box)
Close "Layer Styles" dialogue box
Layer is now highlighted in blue and can be edited.
I am currently running Photoshop CS5.1 on a windows machine which is using Windows 7.
Any thoughts?

Howdy.
Where are you clicking on the layer?
Did you try to reset your preferences by holding CTRL+ALT+Shift as soon as your start Photoshop?
