2 WAE WCCP l2 only 1 gets traffic
Hello
I have 1 router WAN and 2 devices configured in WCCP. The configuration works very well except that only the first WAVE that sees the router and set the WCCP receives traffic. What I mean is that the two waves see the router and vice versa. When I set the WCCP link, the first WAVE to his establishment becomes WAE DRIVING and another doesn't get it packages. If I disconnect the WAE lead or change its configuration WCCP and put again, WCCP switches the other WAE and the other is now exclusevly receiving traffic. No load balancing is reached.
First of all here is my configuration:
1 router WAN Cisco ISR G2 2911 IOS 15.2 (1) T
WAAS in WAVE-274 cisco 2 version 4.3.3 configured in the same way for WCCP.
Router IP: 10.x.y.1/22
WAVE IPs: 10.x.y.9 and 10.x.y.7 22 and default gateway is the router 10.x.y.1
Users are on the same network 10.x.y.0/22 (is that a problem? I read in a WAAS setup guide the WAE cannot be in the same network as the users)
Second, here is the relevant config:
Router:
IP cef
WCCP IP 61
WCCP IP 62
interface GigabitEthernet0/0
Description * LAN connection *.
61 IP wccp redirect in
IP addr 10.x.y.1 255.255.252.0
!
interface GigabitEthernet0/1
Description * WAN connection *.
62 IP wccp redirect in
addr IP WAN_IP...
!
WAAS:
primary-interface GigabitEthernet 1/0
interface GigabitEthernet 1/0
IP address 10.x.y.9 255.255.252.0 (et.7 during the second WAVE)
!
interface InlineGroup 1/1
Shutdown
!
WCCP router-list 1 10.x.y.1
WCCP promiscuity of tcp router-list-num 1 redirect l2 l2-back
WCCP version 2
When I do the following on the router:
show ip wccp 61 detail
or see the ip wccp 62 retail
I see:
The WCCP customer information:
WCCP Client ID: 10.x.y.7

On the WAAS, settings of assignment of WCCP for load balancing is the default: hash. (Hash on Source IP (Service, 61) :))
the method of evacuation is IP forwarding
I have multiple connections from different source IP addresses and somehow they all end up on the same WAE axe:
ConnID Source IP: IP port: port Dest PeerID Accel RR
360 10.x.y.3:49463 10.q.w.36:52732 XX TMDL 16.1%
373 10.x.y.4:55005 10.q.w.36:52732 XX TMDL 24.8%
I checked several places and read the best practices; support for router platform... and it seems that the config is OK

Any ideas?

Has anyone else tried to get the English version of Windows 7 ISO of the MS download site? I have a valid key and the website let me only to get the Korean or French version. English useful MS tech 'UN' told me that the English version is no longer supported and should I install one of these versions and then download the language package and install it. Has anyone else been in this position? It was a horrible experience with the online chat with technical support.
Marcus,
Some people have persevered with contact support via the link on the MS download site and have finally received the download links temporary for an English version. [You will find these discussions if you looking for the Korean forum as most people in your situation included that word in their title of the question. I don't remember one of these threads containing any additional info that would be of no use to you.]
If that does not appeal to you & you still cannot find your original installation disks, then buy a disc-relocation
- Amazon now stock reinstallation DVD for just a quid [the link is for their UK site site American stocks also to them].
- These seem to be exactly what they claim they do not have a product key and that they are specifically described as being for reassembly only - in other words, they are not an attempt to distribute pirated Windows.
- You must use your own product key for activation.
- Make sure order you Windows 7 edition {Home Premium etc.} that is identified on your certificate of authenticity [the label that contains your product key].
- Some of the sellers provide 32 bit and 64 bit DVD, while others provide one or the other. So make sure you order the right kind.
- These discs can do everything what a system repair disc can do, so you'll not need to make a separately.

I'm a little lost here. What could be the problem?
Concerning
Mikkel
Had a look on your config. It seems that all trades are natted, according to me, it's why the traffic in return are not working/not can not get to the ASA. You must ensure traffic of 192.168.201.0/24 for 10.2.0.0/24 are not natted router.
Change your ACL #199 as follows:
access-list 199 deny ip 192.168.201.0 0.0.0.255 10.2.0.0 0.0.0.255 access-list 199 permit ip any any

I can't open firefox - everytime I try I get the above error message. It started after no apparent change or updates to my system, just a normal life stops. I tried to change the .htm, .html etc. register file names and reinstall as suggested, but it does not work. The only way I can open firefox after I reinstalled and it automatically launches a browser.
I can open firefox in a new user account that suggests something has changed in the account that I usually use, but I have no idea what since I didn't do myself any changes and you see nothing that suggests that it blocks firefox to open. I ran a virus scan and it is to come clean.
Does anyone have any suggestions? I would be very grateful for help.
Thank you.
Thank you both for your responses. I had tried all possible ways of opening firefox, including the direct use of firefox.exe and had also tried the suggestions in the link above, but had previously worked.
Having lived every suggestion I could find about the problem I'm afraid, I gave up looking and did a system restore that solved the problem!

do not get traffic of ASA AIP-SSM-20.
Hello
We have Cisco ASA 5510, and we recently added Cisco AIP - SSM. We have configured the sensor and did as well as ASA also but we don't get newspapers in ADM please help me on this.
Please find attached Sersor Configuration and version of the IPS and ASA module.
Kind regards
Nathalie. M
On the SAA, you need
access-list aip-acl extended deny ip any any
class-map aip-class
match access-list aip-acl
policy-map global_policy
class aip-class
ips inline fail-open
service-policy global_policy globalso that it sends traffic to the agreement in principle for inspection.
I hope it helps.

I got my laptop fixed recently, the guy installed windows vista 64-bit, but he missed and windows does more (barely). Someone bought me a new drive for 32-bit windows 7. I get the disc into my CD drive and boot up my laptop, it goes to a black screen for a few minutes with only one under score flashing (_), finally he logs on me and tells me to activate my windows vista or is a black screen that says "Partition: 1" a few other things and he says "/ noexecute = optin", I hit enter and it connects me on vista again.
I want to use my laptop, how to install windows 7 correctly?
In the system Bios set you the cd drive as the first device to boot, then with the victory of dvd in the player you re - start and follow the instructions.
Or when you first start the laptop maybe there's an option on the first screen to select boot from cd/dvd
Of course, it depends on if your laptop unknown supports win7

We have an enterprise Cloud creative license. When some of our users to our Adobe Enterprise Portal and their company ID login allows you to download the product, they get only trial versions offered. We had manually uninstall them other former Adobe products first, we confirmed that the correct E-mail is used, and we tried to create a new Adobe ID. We are unable to install the full product even if our licenses are paid. Any ideas why this happens?
Please refer to: FAQ: what should I do if I have a subscription, but my application acts as if I had a trial?

Hello
I updated Firefox on my computer for 13.01. Now, he struggles to read about 2 sites - both are Joomla and based on the model of JA-purity. What happens is that it fails to load the CSS files to do with the side and the top of the Joomla site menus. The file comes up with this:
because its MIME type "text/html", is not "text/css".
Source file: http://extensions.joomla.org/
Line: 0This error does not appear with other browsers and it displays perfectly in fact in all other browsers.
I'm new on this but I read the following article and think it could be my problem
https://developer.Mozilla.org/en/Incorrect_MIME_Type_for_CSS_Files
Where Im stuck, it's that I did not fully understand what to make of this article, if I could get a step by step guide to fix this problem that would be greatly appreciated.
I apologize in advance if the answer lies somewhere here - I have had a look and couldn't get out.
Thank you

When I try to put the background that is not color. only, I get a black screen.
everything about the definition of the background. accept all I get is a black screen.
Hi Troy,
MSE affect the definition of the background or order so you can exclude as the cause.
When did start? If the latter, try a system restore to before it started to see if that helps. If you use Windows 7, seehttp://www.sevenforums.com/tutorials/700-system-restore.html. If you are using Vista, seehttp://www.howtogeek.com/howto/windows-vista/using-windows-vista-system-restore/. If you are using XP, seehttp://support.microsoft.com/kb/306084. Sometimes this simple process made the rounds and sometimes that doesn't help - but it is easy and worth if she has recently begun.
If this does not work, try to update the driver, firmware, or software for your video card and monitor by checking with the manufacturer of the computer to get the latest for your specific computer model and (your preference based on the serial number), as well as your version of Windows. Be updated via Device Manager, save the changes, reboot and see if that helps.
If this does not work, go to control panel / customization and a more basic theme or background plus standard (and other similar adjustments) try to see if you can find one that works (or partially to work). Then you will know that the question is somewhere in this configuration and it can take time to find something suitable for you.
I hope this helps.
Good luck!
