WCCP mask and weight?

Hello
We're setting up an scenario with datacenter with three WAEs using WCCP to distribute the load.
The core switches are catalyst 6500 so we're using redirect in. L2 redirection and mask to optimize forwarding of redirected packet.
the problem is that the three WAEs are not equal. Two are 612-2GB and the other is a 7341, so we want to use the weight parameter of the wccp tcp-promiscuous command, but I'm not sure if this parameter works also with the mask mode or only with hash mode. And couldn' t find a definitive answer in the documentation.
It's possible?
Regards, Fernando

Fernando,
Typically we don't see/ nor recommend using such different devices, especially in the data center. The 7341 can handle up to 12000 concurrent optimized connections, and the 612-2GB can only handle up 4800 concurrent optimized connections.   So, in the event of a 7341 failure you will lose more than half of the connection capacity you data center can handle.
However, you can use the weight keyword with mask assignment. I just confirmed in my lab two WAEs connected to a 6500 with the following config:
WAE 14.110.3.19
wccp router-list 1 14.110.3.17
wccp tcp-promiscuous mask src-ip-mask 0xf dst-ip-mask 0x0
wccp tcp-promiscuous router-list-num 1 weight 90 l2-redirect mask-assign
wccp version 2
WAE 14.110.3.20
wccp router-list 1 14.110.3.17
wccp tcp-promiscuous mask src-ip-mask 0xf dst-ip-mask 0x0
wccp tcp-promiscuous router-list-num 1 weight 10 l2-redirect mask-assign
wccp version 2
6500 output:
pdi-6500#sh ip wccp 61 det

So you will see the WAE with weight of 90 took 14 of the 16 available buckets.
Sorry for the confusion on the original update.

WAAS: WCCP Mask or Hash on Routers?

I'm starting thinking about using mask assign on an ISR router running 12:4(24)T with GRE/GRE. Has anyone done this before and can you use mask assign with GRE/GRE? We need to use it with GRE/GRE because our egress method has to be WCCP return. My thought was mask assign will be much better at load balancing across multiple WAEs in a cluster than hash because you can specify a long mask assignment. Right now, see more load on WAE than the other and are sometimes getting TFO overload.

The page you linked contains recommendations (in bold) for each platform. On the ISR G2 specifically, you should be able to use any combination of GRE/L2 and MASK/HASH assignment. Some other platforms require specific disribution and redirection methods to maintain the hardware acceleration of WCCP traffic. However, the ISR G2 does not have this requirement.
WCCP GRE and HASH distribution on ISR G2 is typically recommended to make deployment easier. With GRE, content devices can be an L3 hop away (if needed), and it reduces the chance of customers accidentally creating a WCCP redirect loop.
L2 distribution and HASH redirection method should typically require the least CPU and memory load on the ISR. These should perform the best in most cases.
The MASK distribution method gives better controls on how load is divided between multiple content devices, typically at the cost of more CPU and memory utilization. If you have only one or two content devices in your cluster, typically HASH will meet the need for slightly less CPU. As Zach said, most times MASK is used on the Datacenter side to give the ability to 'tweak' how the load is distributed across multiple devices.
Thanks,
Aaron

WCCP Mask change in 4.2.3c

Hi All,
We upgraded the WAE from 4.1.5f to 4.2.3c. We did not disable WCCP in the IOS router before and after the upgarde so the Mask assignment remained the same ( 0x1741).
We have the situtaion where , we need to add a new WAE with code with code 4.2.3c to existing setup which has existing WAE.
How do we change the WCCP Mask assignment to 0xF00 in the IOS router so that we can make both WAE to work in load sharing basis.
Thanks,
-Dhana

Dhana,
Before adding the 4.2.3 WAE to this farm which should have the default mask of 0xF00 configured already, you will need to go to the CLI of the other two WAEs that were upgraded from 4.1.5 and execute the config command "wccp mask is src-ip-mask 0xf00 dst-ip-mask 0x0"
Then all three WAEs will have the same mask value, and it will be safe to bring the 3rd WAE into this farm.
No configuration changes are required on the router.

CS6 problem. When I open the Mask panel, it takes up the entire screen width and the Looks controls disappear, Also, there is a new panel below the Mask panel that seems to have no purpose that I can find. The documentation says "Mask and Look panels - The Mask panel is now placed next to the Look panel. WIth the masking and grading tools placed side-by-side, you can now work faster on the mask workflow." Is there a way to move, hide, or otherwise manipulate the panels for a custom layout? All the examples I can find on the Web show the Looks panel to the left of the Mask panel where the controls are available.

Ok, here is what I have so far. Appdelete the iWork and reinstalled. Pages and Number work, but not Keynote.
Now, I downloaded a couple apps that I need, and no matter what I did, the spinning ball came up and the download stopped till it unlocked itself. It is really frustrating because the download was not completed and whatever came through would not mount. Could this issue be the internet connection? Permission fix showed a lot of Airport issues. I will try to run permissions fix again.

Goods Receipt PO+VOlume and Weight Calculation

Hello experts
i have a GRPO with 10 items in lines. as far as i can see, there are missing in some of the the value for the Weight and the Volume. while checking the Item Master Data form, the volume and the weight are filled up with specific value.
could you please inform me the reason this document(GRPO) has not filled these values for specific items?
also, by clicking the Vlolume and Weight calculation, for these items the the volume is filled and the weight is not.
it is strange i suppose.
what i have found out is that in a Purchase Order, some of the items do not have a Volume or/and Weight because the BP does not have the values noticed to us and these fields are editing in item master data afterwards
By using the System information under the VIew, i can see that the VOlume and Weight Calculation gets data from INV1 table
Edited by: Fasolis Vasilios on Jan 10, 2012 10:56 AM

Hi,
The reason is simple: those value can not be copied if the Item Master was ready when you created the PO. However, PO wont automatically updated when you updated Item master. It stays in the old Item setting. That would be copied to GRPO from the old PO.
Thanks,
Gordon

¿How can I edit a Photo without mask and remain without mask?, ¿How can I edit a Photo without mask and remain without mask?

I want to edit an .png or .jpg image which has no mask and, once edited, that image could remain without mask.
¿Is it possible to do this with iPhoto and how?
Thanks and regards.

iPhoto has no layering or masking. For that kind of work use an external editor:
In order of price here are some suggestions:
Seashore (free)
The Gimp (free)
Graphic Coverter ($45 approx)
Acorn ($50 approx)
Pixelmator ($50 approx)
Photoshop Elements ($75 approx)
There are many, many other options. Search on MacUpdate or the App Store.
You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.

Is it possible to change the font size and weight in an ADF table?

Is it possible to change the font size and weight in an ADF table? I have tried to change the various font size and weight settings for a table and its columns and they seem to have no effect on the font size or weight in a table row.

You would use skinning to modify font-size & weight for the table.

Why use layer masks and adjustment layers?

I've been using PSE and CS successfully for years.
One thing I have never understood is: why use layer masks and adjustment layers, instead of simply creating a copy of the subject layer (the one I want to make changes to) and experimenting with that? It's quick (Ctrl-J), I can do it as many times as I want, I'm not affecting my Background layer. If I like the changes, I can keep them. I can switch the copy on and off to compare with the Background layer. I can do any type of blend or combination I desire. I can insert Gradient layer(s), select any part of the copy and (Ctrl-J) create a new layer containing only the selected part. I can adjust size, rotate, do anything.
It almost seems that "layer mask" and "adjustment layer" are mainly another layer of terminology; can anyone explain (preferably in 50 words or less) how they are intrinsically different from or superior to working with copies of the Background layer? What can be done with them that can't be done simply using copies of the Background layer?

Here's a very basic example of the advantage of using a layer mask.
I have this picture of a sunflower and I want to convert the background to black & white, leaving just the flower in color. I duplicated the Background layer, converted it to B&W and proceeded to use the Eraser to uncover the flower color. But I made a mistake and erased outside the flower. There is no way to correct this other than deleting the layer and starting again.
Now let's use a layer mask on the B&W layer. Set the Foreground/Background colors to the defaults black/white. Using the Brush tool paint on the mask with black to reveal the color. Here I painted too far, revealing a green leaf in the background. No need to start over. Simply switch to white and paint the excess to convert back to the B&W.
Tip: while painting you can type "X" to toggle between black and white.
You could also select the flower using the various selection tools and then fill the selection with black. If it turns out the selection was not 100% accurate you can then fine-tune the result by painting on the mask with black or white as necessary.

PSE 5--what is a clipping mask and how does it work?

Can anyone explain what a clipping mask is, how it works, and most importantly if Photoshop Elements 5.0 has this capability?
Also, are there any tutorials out there that I can teach myself on this topic? I am trying to mimic a layout explained in digital scrapbooking magazine and this technique is used.
Thank you!
Heather

Heather,
You can find one explanation at Janee's tutorials: http://www.myjanee.com/tuts/elements/elemask.htm
Since PSE does not support layer masks per se, the clipping group simulates a layer mask and hence Janee's name for it, "elemask" (cute, huh?)
Here are 2 examples:
In this example I wanted to blur the background leaving the flower in focus:
http://www.pixentral.com/show.php?picture=1euavV1sDqzrEqqqierfc5dSEH9yI01
1. Duplicate the Background layer and apply a Gaussian blur to the new layer.
2. Add an adjustment layer below the blur layer (any kind of adjustment layer will do), but do not make any adjustment - just click OK.\
3. Group the blur layer with the adjustment layer. On the adjustment layer paint the subject with black
to mask out the blur, paint with white to restore the blur.
Of course you can use other tools on the adjustment layer besides the paint brush, e.g., make a selection and fill with the black or white. In some cases it might be easier to first fill the adjustment layer with black and then paint with white.
In this example (not actually a mask but still demonstrates a clipping group) I wanted to crop the picture into a leaf shape.
http://www.pixentral.com/show.php?picture=1ys9Z7FspSwF8HHKGLrxjGVhbTodmF0
1. Use the leaf from the Custom Shape tool to draw out the leaf, creating a new layer.
2. Move the leaf layer below the picture layer.
3. Group the two layers.
Note that in order to move a layer below the Background layer you have to rename the Background layer to anything else (layer 0 in my example).

Can anybody say why In the layer menu the background color is white when opening a layer mask, and why does it automatically turns black by simply opening the layer mask properties menu? The vector mask is white anyway.
