Cisco Application :: ACE 4710 Deployment - Load Balance HTTPS Requests From Internet

Oct 17, 2012

I’m looking for some notes from the field guidance here from those that have much more deployment experience.
 
I have a GSS and an ACE, and its the ACE that's primarily giving me something to think about, in terms of placement and what mode to adopt.
 
The traffic flow will look loosely like this:-
 
Client---Internet---Firewall---GSS---ACE---Servers
 
Physically, it's like this. The RED line denotes a boundary, and pretty much anything North of that is not accessible to us, we simply have a L3 trunk between our switches and "their" switches (S3/S4) and talk using EIGRP.
 
There are other servers in the top tier, some that also require load balancing, some that don’t. Typically, I want to load balance HTTPS requests from the internet, to one of the 3 servers in the top half.
 
I’m not sure what mode to select, routed, one arm? What about placement of the ACE? At the moment, I’ve just configured 1/1 on it and made it part of the MG MT VLAN, it's S VI exists on the S1/S2 switches, so I’m open to change as it's still all in the lab.

Cisco Application :: ACE 4710 HTTPS Load Balance Configuration

Apr 16, 2012

Have two ACE 4710 in HA setup. We would like to setup HTTPS loadbalance(actually just a primary and standby configuration in the serverfarm). Initially this would be for Exchange OWA connections but may expand to more HTTPS connections later. I know there are several ways to do SSL with the ACE( client, server, end-to-end). I am just wanting to know the easiest way to deploy this? Is a certificate always needed on the ACE for each connection? In HA mode would a certificate be needed for both or does it replicate in some way to the other ACE?

Cisco Application :: ACE 4710 Load Balance Only If Primary Server Fails

Oct 14, 2012

I've done a lot of ACE work over the years but this is the first time this has ever come up. 
 
I have a request from an application group where I have 3 rserver in the server farm but they want all traffic to only go to the first server unless that server fails.  If the first server fails, only then do they want traffic to go to the 2nd server instead and if that fails, then traffic goes to the 3rd.
 
I've read through the documentation but haven't figured out a way to do this. What to do this type of failover configuration?

Cisco Application :: ACE 4710 Giving Mangled Http Requests In Apache Access

Oct 21, 2012

After replacing a Cisco CSS/SSL  Accelorator and PIX firewall with an ACE 4710 to do load balancing and  SSL encryption behind an ASA firewall we started seeing mangled HTTP  requests in the Apache access logs for the servers in the server farm. This is occurring for several different URLs and not just the one above and for multiple web browsers.The ACE load balances to servers running Tomcat 7 with Apache HTTP server v. 2.2.14. A recent ACE software upgrade to A5(2.1) has not fixed the problem.

Cisco Application :: ACE 4710 With HTTPS Redirect

Sep 20, 2011

i have ACE 4710 appliance that terminate SSL and the connection to the servers is http.
 
The ACE (one Armed) is load balancing between two web servers and i am using stickness in order to take the connection on the same server based on cookie.I can access the website either by http or https., where on the web page there is a login credential to access using username and password.
 
When i access the website using https everything works fine and i can login to my account in https mode.When i access the website through http and login to my account the URL is redirected to https...normal because i am using action-list to rewrite the http into https. But when i exit the browser and access the website again using http it is not redirected to https(although i see that i am still login into my account i can see all the inforamtion in my account).
 
The customer wants the connection to be https even when i exit the browser and access the website again (within short time before the cookie exipres)

Cisco Application :: CSS Or ACE 4710 Redirect HTTPS To Http

Feb 27, 2012

For a CSS with a SSL module (performing SSL termination) - is it possible to impliment a redirect on https URL to send to equivalent http URL.If my understanding is correct, the CSS will do SSL termination and then use an http content rule on the resultant http stream as it is recursively handled by the CSS ? This would mean that the SSL module has no way of seeing/acting on layer 5 and above data (i.e. picking up on a specific URL) and can not itself issue a redirect - i.e. you could not associate a redirect statement or service with the following ssl content rule ? [code]The CSS would instead rely on a http content rule to impliment a redirect - i.e. you would have to associate a redirect statement or service to the following http content rule instead?
 
But if the CSS is already handling traffic for existing url...  traffic that is going to cause a loop when a client goes direct to. url...I realise the requirment is uncommon / a bit convoluted, its one of those don't ask type scenarios - aimed at achieving a specific requirement.Would the ACE 4710 be able to handle such a scenario any differently ?

Cisco Application :: ACE 4710 Webpage Very Slow To Load When Going To ACE

Aug 13, 2012

Experienced the same sort of behaviour with an ACE 4710 version A3 (2.5). When trying to connect to a webpage on port 443, the pages over 1 minute to download fully. I have timed the download using the plug-in firefox. What is strange is that the browser successfully makes the connection, 200OK etc,  but each 'get' takes a very long time to transfer. If I go directly to the server and don't pass via the ACE the page takes between .7 and 1 second to transfer.Is there a way to speed this transfer up, I am currently looking at connection maps.

Cisco Application :: ACE 4710 Load Balancer Usage

We are using Cisco ACE 4710 for load balancing the servers. The predictor used is 'least connections'.Have observed the below;The number of connections for a particular server in a serverfarm is 15 in the Cisco ACE.The actual number of users in that server is 6.All the users access using the VIP.Still i couldn't understand why there is difference in the number of users in the server and the load balancer statistics.

Cisco Application :: ACE 4710 (1) SSL Certificate Import ( 2 ) With Load Balancing?

Dec 3, 2012

I am performing a deployment, in which i require clarity on the following. Our setup has DC and DR , in each site we have two devices for HA.We have received One SSL Certificate from Public CA, Kindly clarify the following doubts i have on thisIn Doc, i found Cert.pem and key.pem is required to generate the pair ,do i receive both Cert.pem and key.pem from the CA or we can generate key.pem from Cert.pem ?SSL Offloading is planned for the X application, and it is running in both DC and DR ( Considering each having their own Public IP address ) , do i need to have two different public certificates or a single certificate can i use in both DC and DR.Load Balancing IssueIs it possible to configure in ACE to access the service in Business hours and in non Business hours to display HTML page showing this is available only during these hours ?In DC we have Three Web Servers ( only in One physical server the service is active, other two are backup ), and these three servers are under cluster and shares one cluster IP , In ACE we have created the VIP and Pointed to only Cluster IP ( like pass through only ). The issue we face is if active web server is down, even then ACE is sending the traffic to that webserver only instead of sending it to the new Active web server. let us know if any solution is there to overcome this issue ?as per my understanding instead of giving cluster IP as real server IP we can issue the three physical servers. now i dont require load balancing between three servers instead require failover king like if first server is down then it should forward to Second server ?

Cisco WAN :: 2800 Load Balance Internet Multiple ISPs

Jan 9, 2010

what you're doing to load balanace internet traffic?  I'm interested in load balancing internet traffic (outbound -AND- INBOUND) using multiple (at least 2) ISPs.  Some of the methods I have used in the past have certain weaknesses.. basic DNS load balancer (relies on multiple IP addresses per host), OER/PFR (ability to control INbound is limited unless complex configuration and coopearation with ISPs)...  This is kind of a broad open ended question.. It seems like something that would be a common issue and am wondering what other are doing with the capabilities 2800, 2900, 3800, 3900 series routers..
