Cisco Application :: ACE 4710 Cookie Based Stickiness

Jul 23, 2012

We have ACE 4710, It is configured with IP based stickiness and working fine for a web application server (BMC Remedy). We tried configuring cookie based stickiness for the same server. Server application is having JSESSIONID.But after configuring cookie based stickiness, there is an issue that the first page is coming for entering login credentials and after entering it the page is blank or not responding.  What is the pre-requirement for configuring cookie based stickiness in ACE for BMC Remedy web application and which type of cookie based stickiness is suitable or possible?

Cisco Application :: 4710 - HTTP-Cookie Sticky Not Working

Feb 1, 2012

I have a requirement to load balance OWA 2010 inbound connectivity to 2 CAS servers using a ACE 4710 with sticky sessions enabled.
 
The CAS servers are currently responding on 80 or 443 at this moment in time. Eventually I want to off load the SSL to the ACE 4710, its currently running on the CAS servers. I need to enable sticky sessions to keep the session to the same CAS server for each internet based connection. I also have a proxy enabled for inbound connectivity so I cannot use source IP.
 
Here is my configuration but it doesn’t seem to be working, i am currently testing with port 80 connections not SSL.
 
serverfarm host INHOUSE-EXCHANGE-OWA-vFARM
predictor response app-req-to-resp samples 4
probe 443
probe HTTP-PROBE
rserver INHOUSE-TEST-CAS01-SVR
   inservice(code)

Cisco Application :: ACE4710 Insert Cookie - Does It Overwrite Server Cookie

Mar 28, 2012

I was trying to implement stickiness based on cookie. Server inserts a cookie and sends it to the browser. I learned from app team that this cookie is changing dynamically during the session, so stickiness based on server’s cookie doesn’t work.
 
Now I want to investigate into possibility of ACE to insert a cookie. My question is: ACE feature of “cookie insert”: does it add additional cookie into http header without removing server cookies or it deletes the cookie(s) that server put into http header and replaces them with its own cookie?

Cisco Application :: ACE 4710 Inline VS One-armed Based

Apr 3, 2012

I have 2 basic questions I am having doubts about it and would love to have some clarifications:
 
1) I configure in one ACE4710 (running 4.2.2) context a bridged interface and in another context the same interface, like here below : [code] Then I move to the Juniper context and I try to create an interface (either L-2 or L-3) but it doesn’t work: [code] So if I configure an interface as bridged in one Context, I cannot configure it in another context??
 
 2) If I want to migrate in context Microsoft from One-armed to inline (L-2 bridged), can I migrate one service at the time ( I.e. the config i showed above for context Microsoft, would it work also for one-armed based???)

Cisco Application :: ACE 4710 Farm Selection Based On Source IP?

Jul 5, 2011

I have a requirement to select a farm based on source IP address.  I tried creating a match all class-map that matches on the virtual-address and source address but I get this message.LB01/Admin(config-cmap)# match source-address x.x.x.75 255.255.255.255 Error: Only one match virtual-address is allowed in a match-all class-map and it cannot mix with any other match type To me this is the only place where it makes sense to set the source match criteria.

Cisco Application :: CSS 11503 Session Stickiness Configuration

Sep 17, 2012

I only have configured load balancing on apache with a very simple setup. I have to deploy 2 applications on my clients environment that run inside jboss. One of these applications needs session to be sticky to work properly. The other does not.
 
In apache I can configure is the sticky parameter is true or false, based on the url, like /appA/* is sticky and /appB/* is not sticky. Can I do that in a CSS 11503? My client insists that it is impossible. That the CSS is only ip based.
 
I copied the configuration below from the manual: owner arrowpoint # content ruleWapSticky

Cisco Application :: ACE20 / Configuring Timeout For IP Address Stickiness

Jan 18, 2012

We are using an ACE20 module running version A2(3.2).I have a question regarding IP stickyness and the timeout parameter.I found this in the "Server load balancing configuration guide" (in a section entitled: "Configuring a Timeout for IP Address Stickiness"):
 
"The sticky timeout specifies the period of time that the ACE keeps (if possible) the IP address sticky information for a client connection in the sticky table after the latest client connection terminates. The ACE resets the sticky timer for a specific sticky-table entry each time that the module opens a new connection or receives a new HTTP GET on an existing connection that matches that entry."
 
The parts in bold seem to point to the fact that the timeout is an "inactivity timeout" as the counter is reset on every new connection.The next section in the documentation is entitled: "Enabling an IP Address Sticky Timeout to Override Active Connections" and says:
 
"By default, the ACE ages out a sticky table entry when the timeout for that entry expires and no active connections matching that entry exist. To specify that the ACE time out IP address sticky table entries even if active connections exist after the sticky timer expires, use the timeout activeconns command."
 
This seems to contradict the previous statement.So my question is: is the IP stickyness timeout an "inactivity timeout" or not?

Cisco Application :: 11503 - Stickiness Not Working Fine Without Clearing Session Manually

Sep 11, 2012

We have a pair of CSS 11503 installed in our DC. Stickiness is configured for one of the application since long back and was working pretty fine till last couple of months. Since last two months, we observed that CSS is not distributing sessions the way it suppose to be. Mostly, it forwards the session to same server even though request is coming from different sources. Once we refresh the sessions manually, it starts working fine. We have to do this exercise manually every alternate day.

Cisco Application :: Cookie Insert On ACE20-MOD-K9

Nov 13, 2012

We are using an ACE engine module(ACE20-MOD-K9) provide loading balancing service for two WEB servers and configured cookie for stickness. Below is the current configuration and it seems working fine now.
 
The problem I was facing is before use parameter-map change the http header length to 8k the stickness doesn't really working properly. User complains that their working session constantly be kicked out and redirect them to login page. By tracing traffic from a client we found that sometime ACE fails or stop insert the configured cookie, after increase the header length ACE start getting work.
 
how does the header length setup effect ACE to insert a cookie? Will the cookie insert attmpt fail if the header is longer then the maximum length configured on ACE? [code]

Cisco Application :: DNS Rewrite On ACE 4710?

Aug 26, 2012

I have an issue with a customer that wants to update a server behind the ACE. The problem is that when the application wants to update the server it does it with the name.Doing some research I found that you can rewrite the record DNS based on the static NAT you set up on the ACE. The feature is called DNS inspection. Is the same feature as the ASA (DNS doctoring).I apply it to the outside interface and it did not work.

Cisco Application :: ACE 4710 Lic Performance

Mar 19, 2012

With the current (A5) ACE 4710 lic setup, does the "X gigabit per second appliance throughput" that is licensed affect: -
 
A)  Only "appliance" i.e. load balancing traffic, any other normal routed traffic is not included in the limit
 
 or
 
B) Is it an overall throughput limit on the interfaces i.e. includes all traffic not only load balancing traffic but also normal routed traffic crossing the appliance
 
Looking at a scenario where the lic size I need for HTTP load balanacing would be one size if  A) but would need to be much larger is B) to accomodate out of hours routed backup traffic crossing the ACE 4710

Cisco Application :: ACE 4710 - SSL Over Port 80

Aug 11, 2012

I've got a web app that the owners want to run over port 80, but also using SSL to secure private data in transit.  The architecture is an ACE 4710 in SSL termination mode->Apache (port 2000)->Back-End app server.
 
I've got two VIPs set up already - one on port 443 and one on 2000 - both of which do the SSL termination quite nicely, but using the 3rd VIP set up on port 80, the connection steadfastly refuses to be HTTPS (i.e. doesn't show the padlock).
 
I've done all the set-up through the web interface so far, can this be done? If so, how?

Cisco Application :: ACE 4710 Upgrade To A4 (2.1)?

Jul 19, 2011

I am currently running A3(2.6) and evaluate the possibility of upgrading to A4(2.1). The Instal & Upgrade Guide A4(2.0) mentions that A4(2.0) does not include all features of A4(1.1). Does this apply to A4(2.1)? The Release Notes mentions a list of features merged from A4(1.1) to A4(2.1) but does not clarify if there any features not merged.

Cisco Application :: ACE 4710 A3 (5) Logging New Connections?

Jul 31, 2011

We have recently transitioned one of our Ecommerce products to a new data center, at which we now use a one-armed load balancing approach rather then the routed load balancing approach we used previously. This is casuing us some issues as we generally log the source IP address a user comes in on when he fills out an application. Now the logs only show the natted ip address recieved by the load balancer, which does us no good. Any way to log the source IP address when a new connection is created to a particular vip?

Cisco Application :: ACE 4710 Take An Action When A Server Goes Down

Jun 2, 2011

If we use an ACE4710 to load balance two real servers, obviously it will use health checks to determine if a server is down.When it detects a server is down, it will not send it any more traffic.But can we also have it take any other action?  For example maybe email an admin, or send an SNMP trap?  Or better yet, can we use a custom TCL script to do other things, like launch some custom activities?

Cisco Application :: ACE 4710 To Manage The Ports

Jan 24, 2012

I am new to the 4710 appliance.Apart from the 4 GE 'data' ports, there are 2 Ethernet 'management' ("console") ports.  I find the description in the "quick start guide"somewhat confusing. URL, Is a first-time serial connection (at least to run the initial config. script) mandatory?  Or can you obtain the same result via one of the 2 Ethernet management ports and using a default ip address (192.168.1.10 ? When running the initial config. script (only possible from the serially connected console i suppose), you have to select your management port. Why does the system in step 5 proposes  you 4 ports, and not just 2? I suppose the intended port for management is one of the 2 management ports, not one of the 4 data ports?
