CSM-Content Switching Module

Hi All,
How to shutdown Content Switching Module in Cat 6500 switches ? I want to shutdown only CSM-Module without disturbing Chassis.
Can anyone please send me the command on that ?
Highly appreciate your valuable reply.
Thanks,

Hi,
Assuming you are using IOS, you can power-down a module in a 6500 chassis using the command
"no power enable module " in global config mode where is the slot number of the CSM.
If you are using CatOS then the command would be:
"set module power down "
The CSM should be hot-swappable so you should be able to just pull it out of the chassis, but I think that is a bit vicious if you only want to shut it down.

CSM(content switching module) supports the 2 tier server load balance ?

hi everyone,
Does any know the CSM support 2 tier server load balance ?
this means that CSM perform the server load balance for servers and the same servers require another time Server load balance. In the other word,
the CSM supports server port and client port for server load balance ?
thanks
fred.

Hi, this seems to describe a typical case of multi-tier design where the CSM needs to handle 2 types of connections:
1. clients->CSM->serverfarm1
2. serverfarm1->CSM->serverfarm2
We usually refer to the second type of connections as server-to-server load balanced traffic.
There is no problem in handling that scenario with the CSM and you have a few options.
In particular, each virtual server on the CSM can be configured to only accept incoming connections from a specific VLAN, so you can use that as an additional security measure or to distinguish connections based on which VLAN they come in from.
If you want to, you could even configure the CSM with 2 virtual servers with the same exact virtual IP and L4 port, but listening on 2 separate VLANs (the client-side VLAN and serverfarm1 VLAN) and use a different server farm based on that.
One important thing to keep in mind when handling server-to-server load balanced connections: if serverfarm1 and serverfarm2 are on the same VLAN, you have to configure "client NAT" for the server-to-server connections, to force the return traffic back to the CSM.

Content Switching Module (CSM): Sessions stuck in closing state

Hi guys,
I'm troubleshooting a CSM with 4.3(1).
We migrated a real server from windows to linux, since then lot's of sessions stuck in closing state until the idle timer expires.
I traced the traffic from the client to the csm and from the csm to the real server what I saw is the following behaviour at the end of a session:
windows real server: client sends FIN -> real server acks the FIN -> real server sends FIN -> client sends RST -> real server sends RST -> CSM deletes session from session table
The linux real server mostly behaves like the windows real server but sometimes behaves as follows:
client sends FIN -> real server sends FIN, but does not ack the FIN sequence number of the client -> real server sends RST -> client sends RST -> CSM does not delete session from session table, it stucks in closing state
Does anybody know how I can solve this problem of half-closed sessions other than decreasing the idle timeout?
Is it possible to configure CSM to close and delete sessions not only on FIN-ACK packets but also on RST packets?
Or to use a different fast idle timeout when sessions are half-closed?
Many thanks in advance,
Thorsten

Hi Fabrizio,
CSM_FAST_FIN_TIMEOUT is already set to 10 seconds.
What I found out while testing is that CSM_FAST_FIN_TIMEOUT works with configurations where idle timeout is configured > 0.
But when idle timeout is configured to 0 (what meas no idle timeout) the csm seems not to use CSM_FAST_FIN_TIMEOUT: Half closed sessions will stuck in closing state.
Any idea why cms behaves this way?

Thorsten

Cisco WAAS and Content Switching Module compatiblity

We are planning to implement WAAS on our hub's 6500 core switches, so that TCP connections from the end sites users to the servers in the hub can be optimized. But we have the servers VLAN groups under the Cisco CSM module already. Are the client-server connections still able to be optimized by WAAS?

Hi Joe
let's seperate out the two topics here.
a) WAAS traffic interception with wccp
b) CSM
a) when you say vlan 200 is where target servers are connected, is that the CSM client side vlan? or the actual server vlan ?
the bottom line is you need to make sure the interface where you configure "ip wccp 61 redirect in" is recieving traffic from servers towards .
Good reference for WCCP best practices in 6500
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/white_paper_c11-629052.html
b) yes you can configure stickiness for session persistance as in below URL

Ciscoview device manager for content switch module not available for download ?

Hi,
On Cisco support site CVDM is no longer available for download despite that warning message says it won't be available since February due to migration to another server. Any idea where to get it for my CSS11501 ?
Cheers
Arun

If you use the old link:
http://www.cisco.com/cgi-bin/tablebuild.pl/css11500-crypto
You'll get redirected to CVDM for the CSS11506. It's the same CVDM software as the CSS11501 and CSS11503. Don't know why only the CSS11501 link is broken.

Multiple context on Cisco Content Switching

Hi Everyone
I had new case with Cisco Content Switching design. The current network has two Cisco Content Module (CSM) and each of them response for switching content on one Vlan.
Now i want to reconfigure it, to meet the redundancy requirement. But i don't know Cisco Content Module have same idea of design with ACE on Route Mode.
I want configure CSM with two or more vlan pair in routed mode and it can HA between each other.
Thanks
Phai La Quy

Hi Phai,
Yes you can configure CSM in routed mode with clients in one VLAN and server in another. Pasting the link for your reference. You can find more in routing and switching guide.

Specs for 11500 Content Switches

I am looking for more specs on the 11500 series content switches. Specs such as http connections per second, tcp connections total.

Ted,
The following link:
http://www.cisco.com/en/US/products/hw/contnetw/ps792/prod_bulletin09186a008017dc5d.html
states that "A Cisco CSS 11506 can now achieve more than 45,000 TCP connections per second and, if configured with 4 SSL modules, can attain over 4000 SSL transactions per second."
Is that what you are looking for?
Keep in mind that performance will be slower with layer 5 rules than strictly layet 4 rules.

Smartfilter with Content Engine Module (NM-CE-BP-40G-K9) & ACNS on 3661

I've been looking over the CCO docs, but can't find one that has sample configs for using a 3661 router containing content engine module, smartfilter, & ACNS. Topology is basically the following...
(PC's)----(LAN Switch)-----(3661 w/content engine module)----(PIX)---(internet)
I don't want to creat a new IP subnet for the 3 interfaces within the content engine module/router. I want to use the IP's from the current LAN IP Block.
Any advice appreciated.

I thought this might help.

Content engine module

Hi, is it possible for a content engine module to work in a 2600 with the following scenario? I want the clients gateway to be the 2600 with content engine installed but I want the 2600 to forward all traffic out a seperate gateway. I know a content switch can do this but can a content module in a 2600 do it too. The reason for wanting this is I want to use url filtering software such as websense and at the moment the existing gateway/firewall is not compatible with websense so Im looking to use a 2600 with content module installed to filter webtraffic and forward out the existing gateway. Thanks

this is no problem
Just look at the nm-ce as a standalone device connected by ethernet to the 2600.
The 2600 can be the default gateway for the client and the cache [nm-ce].
The 2600 will intercept traffic from client and forward to nm-ce.
The nm-ce will use the 2600 as its default gateway.
Gilles.

Regarding content switch

7. Companies doing business on the Web are experiencing traffic spikes and dramatic increases in the number of users hitting their site at any one given time. Foundry claims support for up to one million concurrent connections, but your high-end content switch (css) today now supports only one-third of that amount, how do you respond?

The data sheets report 1 million concurrent connections for the CSS 11800, and 2 million for CSM. Where are you getting your numbers from?

Cisco Content Switch 11503

Directed towards any users of this product line out there.
I have a client who is on the older hardware platform (11100);. and is
looking to invest in a pair of new switches/balancers. I have the follwoing
outsntanding questions that i'm needing to confirm on the 11503
- Source NAT - is this required to always be on? for marketing, reporting and debugging purposes, we're wanting to ensure we can have the client's original ip address preserved once request hits web/app, not rewritten at the content switch.
- sessions - any concerns running up to 30 - 50k of simultaeous sessions on
the 11503? require the the addt'l session accel modeule?
thanks for the input.

Byron,
source nat is not a requirement of the CSS.
It depends how you design your network and where you place the CSS.
If you do not want source nat, make sure the servers are placed behind the CSS and that the path from server to client always goes through the CSS.
For the amount of connections, each module can handle up to 200k concurrent connections.
So, the CSS with only 1 module should be ok.

Content Conversion module in JMS Adapter - MessageTransformBean

Hi All,
We are using Content Conversion module using MessageTransformBean in JMS adapter to read a flat file from MQ Queue.It works fine and the file is getting picked and successfully converted into a xml structure in XI.
The flat file is multiple line file with each line as one xml record.But the xml structure after conversion has only one record in it.So we end up getting multiple messages each with one record instead of ONE xml structure with multiple records in it.
Could I know why I am not getting multiple records in one xml structure as expected.
Do I need to change xml.structureTitle as MyTitle,* or should I put something endSeparator like we do in File Content Conversion.
Any Help appreciated.
Thanks,
V

Thanks Shabarish .I did follow the same document , but the xml is not converted as multiple records in it .we are getting only one xml message for each record in the file .
The xml structure we are getting :
<ns:MyDocument xmlns:ns="http://xi.com/test">
<MyTitle>
<field-name1>111</field-name1>
<field-name2>222</field-name2>
<field-name3>333</field-name3>
</MyTitle>
</ns:MyDocument>
We need onle one xml message instead as below.
<ns:MyDocument xmlns:ns="http://xi.com/test">
<MyTitle>
<field-name1>AAA</field-name1>
<field-name2>BBB</field-name2>
<field-name3>CCC</field-name3>
</MyTitle>
<MyTitle>
<field-name1>111</field-name1>
<field-name2>222</field-name2>
<field-name3>333</field-name3>
</MyTitle>
</ns:MyDocument>
Any Help ...

Complex XML to Plain in JMS adapter "Content conversion module"

Hi!
I have read the document on "How To use the content conversion module with XI3.0 J2EE JMS Adapter", and it says only SimpleXML can be converted in the receiver channel.
I had hoped for a solution at least as good as in the File/ftp adapter, where complex XML can be transformed to files.
Are there plans to include complex XML conversion in the JMS adapter?
I can not use the file adapter as I need to change the file name and destination, and that can not be done by adding own module to its single module.
Any idea how I can achieve what I want?
To only way I can find, is to create a file using the file/ftp adapter, and then pick it up again and treat all the lines as the same structure (one row = one xml field). Then output this new xml message to file, using the JMS adapter and add any modules with name and destination determination.
Appreciate any help!
Regards,
Oeystein Emhjellen

Hello,
Have you tried to use an XSLT mapping within the IE?
I have, at one customer site, created a XSLT message mapping which converts the XML to a fixed length ASCII file format. I than added the XSLT message mapping as a second mapping step on the interface mapping.
In this case I was able to publish a fairly complex fixed length file format to MQ Series via the JMS adapter.

BUG: Ctrl+Alt+ number to switch modules only works with number pad

Really annoying, since this worked nicely in the beta. If, for example, you hold down Ctrl+Alt+1 (pressing 1 on the top row of the keyboard) to switch to the Library Module, it doesn't work. If you use 1 on the numeric keypad, it works fine. What's the big deal, you ask? Well, try using the number pad on a laptop - you either get to use the number keys or the regular keys, so this shortcut is essentially useless on anything other than a full-size keyboard.

Windows treats Ctrl + Alt shortcuts as special. They are used as hotkeys for desktop icons, and if a key is used for that purpose, it overrides any use within a program. I did a little research, and setting a desktop hotkey to 3 will cause your LR symptoms, where you can't used the normal numbers and have to use the keypad to switch modules. On the other hand, you'd probably be seeing the effect of using the non-number-pad keys (they'd launch a program), so it's a mystery.
In my testing, I noticed that the Firefox browser uses that key combination to switch between its tabbed sessions. If you're running that program, you could test to see if it exhibits the same symptoms.
