WAE612 Content Engine load restriction.

Have wae612 deployed as a content engine thru WCCPv2.
We are mobile operator. I have many GPRS subscribers that are NATed by cisco to one public IP address prior to go to CE.
The problem is that GRPS user starts 2-3 downloads and CE loads it very fast but user can load the objects from CE only at 70-100kbit/s. So when I divert all GPRS users thru CE, my internet link becomes stuck because CE loads many files at all available bandwidth and then give it to customers at GPRS speed.
How to make CE not to download a new part of file unless the old part is already loaded by the user?
Tried Squid on linux - the same issue.

SOLVED --
The mistake was my own...in writing this post and re-testing, I realized I had made a foolish mistake. I applied an access-list (which I forgot to include) to the "ip wccp web-cache redirect-list bypass_content_engine" in the global config of the router.
When I installed service 95 for spoofing, I automatically added the same access list to it as well.
This was not a good thing since the access list denied packets with a destination of our internal IP addresses from going through the content engine. This worked fine on the way *out* of the router. But as the now-spoofed packets returned, their destination was an inside IP address and they were pretty much discarded. Foolish Mistake!
Removing the ACL from the "ip wccp 95" statement in the global config fixed the issue and I am spoofing fine.
Sorry to waste time...

Cisco Content Engine for Content Filtering

Hi All,
I am looking for a low end solution for Content Filtering and would like to use Cisco Content Engine.
1. The documentation said that Websense, Secure Computing SmartFilter (does not require separate SmartFilter) & N2H2 support is there on the CE. I used configurator on CE 510, but it did not give me option for any of those. I would appreciate any input in this regard.
2. Also, I assume that once I get a Content Engine, I don't need to use Microsoft Proxy any more, please confirm.
regards,
Ahmer Ghazi

You would have to Install the Smartfilter software on the Content engine that would work with the ACNS software running on the CE. SmartFilter software operates inside your network to control user access to external Internet resources and allows you to restrict access to World Wide Web pages, newsgroups, and FTP sites.
For more details refer:
http://www.cisco.com/univercd/cc/td/doc/product/webscale/uce/acns41/smrtfltr/sf_chap1.htm
The Content Engine does the job of storing content locally and serving it to the users, so you would not need to use the Microsoft Proxy.

ACNS - Content Engine Pre-Positioning Video

Is it possible to load content onto a Content Engine CDNFS partition directly without using CDM? We have large videos that we would like to get the content from a PC to the Content Engine at the remote location

Hi,
The CDNFS partition and its database is managed exclusively by the CDM Manager. You can't upload files directly to that partition without using CDM. Thanks!
I hope this helps!

Content engine for video on the LAN

Hi
I have a video server on the LAN. I want to position the content engine on the LAN to use it for stream splitting to avoid loading the video server. Can i do this i.e. placing the Content engine on the same network as the source? Or could I use the Content engine module on the router. If so then how do I connect it?
Thank you
Sanj

I suggest that you use the content engine module on the router.

How to show a splashscreen in a FLASH AIR game while content is loading

Hi,
I've seen some games take some time to load (something completely reasonalbe and normal). So I guess it would be really interesting to have a way to show a splash screen while the content is loading.
Any common aproach to face this problem?
Thks.

The solution is generally to break up the operation that is taking a long time into smaller chunks. If for example, you have a long loop executing, then AIR never gets a chance to update the screen (or respond to the OS messages).
The first step is to identify what part of the process is taking such a long time.
See http://senocular.com/flash/tutorials/asyncoperations/ for a good explanation.
And to put up a progress bar, you have to do this anyway, otherwise the progress bar will never get updated, either.

Content Engine compatability with Windows Media Player

I am currently running ACNS version 5.5 on our CE510 Content Engine. We want to set this box up to serve VOD requests from WMT. I think the clients on site are all using Windows Media Player version 10. Does this version of ACNS software work with Windows Media Player 10?

Dan
this brings up an interesting point. The content (which is canned Video on an Intranet Web site) is HTTP? I am wasting my time here by trying to use the Windows MP services?? Perhaps I already have what I need...
Your comments appreciated.

Should the Cisco Content Engines be used as a proxy appliance

Should the Cisco Content Engine be use as a proxy appliance like a Blue Coat appliance, Squid cache engine, ISA server, etc...
I am pretty sure it is but just need some feedback on past experiences. Customer would like to by a Cisco product for Web filtering/proxy.
or is it strictly used to help with web base applications.

HI,
the CE is basically able to check every request it supports. If you are using 3rd level products like smartfilter, websense or webwasher you can use the features of those products to supress/forbid certain requests(i.e MSN etc.)
Kind Regards,

Help!!! Content engine

my configuration is follow the attached file. I don't know what is wrong with my content engine using as a cache server. when i connect this CE to my network, i can make my user access to the internet fast only 2 days, but after 2 days it makes my users internet connection slow. So when users access to the internet slow, i disconnect this CE from my network, then my users internet connections is running better. So please help me to find what is incorrect with my configuration and what commands i should add more to this current configuration"

Content Engine Problem

Dear All,
My apologies if this posting is on the wrong board.
I've a problem with our content engine returning an error of:
"Tre reply from server is not valid"
The URL of the site is http://hiring.monster.co.uk/jobs/createtitle.aspx?mode=qb.
I've attached a screenshot of the error message.
Any advice or help would be greatly appreciated.
Thank you in advance.
Sinh

This symptom is observed on a router on which Web Cache
Communication Protocol (WCCP) is enabled and Cisco Express Forwarding (CEF)
switching is disabled. If the caches are Cisco caches, they will be running
software prior to ACNS 4.2.5.
solution: Ensure that CEF switching is enabled on the router. If this is not possible, the impact of the problem on the cache will be minimized if the authentication bypass function is disabled.also try upgrading IOS to 12.1(18.01)E which may solve the issue.

Content Engine transaction logs -- monitoring and analysis

At our remote sites there's a local Cisco CE511 to ease our WAN bandwidth. I have been tasked to find a method to gather CE usage for trending and troubleshooting.
From my search on the internet I decided to go with the Webalizer application. I setup the CEs to export their transaction logs every hour to my FTP server. After a test of Webalizer on a log file, it produced a nice HTML report for that hour.
I would like to discuss with anyone on bringing this up to a new level. I would like webalizer to run as a cron job, but the log file names changes every hour. So that's a hurdle I need to figure out. Also keeping track of user web hits is important. I would like to make sure my reports are accurate in reporting what IP address is the top talker.
I hope this will start a productive exchange of ideas. Thanks.

Simple Network Management Protocol (SNMP) is an interoperable standards-based protocol that allows for external monitoring of the Content Engine through an SNMP agent.
An SNMP-managed network consists of three primary components: managed devices, agents, and management systems. A managed device is a network node that contains an SNMP agent and resides on a managed network. Managed devices collect and store management information and use SNMP to make this information available to management systems that use SNMP. Managed devices include routers, access servers, switches, bridges, hubs, computer hosts, and printers.
An SNMP agent is a software module that resides in a managed device. An agent has local knowledge of management information and translates that information into a form compatible with SNMP. The SNMP agent gathers data from the Management Information Base (MIB), which is the repository for information about device parameters and network data. The agent can also send traps, or notification of certain events, to the manager.

Should the Content Engine work while the Inernet link is down ?

I have installed CE590 in a client network
The http saving performance is from 30 : 40 %
My client want to make sure the CE is caching the web site
He want to shutdown Serial port of the main router , and try to browse web sites. ( the Cached sites )
Should he get a reply from the CE and browse the cached sites ??
I mean , Can the PC browser ( while the internet is link is down ) open page like www.yahoo.com for example if it is cached on the CE ??
Is there is any command of the CE that can display the name of the cahced web pages ?
Note : Cisco Content Engine Software Release 3.11
Can anyone help me ?
Thanks
Mohamed Abdallah

Mohamed,
Before you go any futher you need to upgrade the CE to ACNS 4.2.3. There are known issues with 3.1.1.
To answer your question the CE will only server content if it can not access the internet if the object is fresh. By this I mean the object has not expired or the object does not need revalidation eg If modified since request.
This could cause problems with broken pages etc etc.
Your best option is to turn on transaction logging.
transaction-logs enable
You can then go to the local1/logs directory on the CE
type working.log
This will show you the urls that clients are requesting and if they got a hit / miss/ ims hit / ims miss etc etc.
Overall your cache should always have access to the origin server for content.
Cheers
Phil

WebCenter Content | Batch Loader

Hi All,
We have to checkin 1 million (approx) scanned document in WebCenter Content 11g.
We are planning to use WebCenter Content Batch Loader feature for this.
Is there any limitation with Batch Loader in terms of volume, performance.
Also is there any guideline available for Batch loader best practises.
Thanks in advance !
~ Piyush

Assuming you are saving the files to a file system rather than in the database be sure to understand how metadata spreads content out in the file system. Performance of the hardware can degrade significantly if you have too many files in a folder.
When using Batchloader on scanned images i commonly set dAccount = year/month/day of the document creation or scan or anything that helped spread out the content.
Also I found working with batches of 10,000 at a time to be a good number and would run multiple batches at the same time.
Turn the indexer off before you start and on again when you finish then do a reindex with a fairly large batch size, 2500 seemed a good number for me, though with scanned images this wont matter as much.
Batchloader worked great.
