Cisco Application :: ACE 4710 Load Balancer Usage

Dec 13, 2011

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 :: How To Capture Packet In Load Balancer CSS11501

Jan 15, 2012

how to capture the incoming and outgoing packets on the balancer?The load balancer is connected in between the customer DCN and cisco switches 2960.The reason of capturing both incoming and outgoing packets on the balancer is to prove to our customer that there is no packet loss issue on the balancer, and it could be some issue on their DCN network.Since it is a production server, I will need to ensure that there is no impact to the incoming and outgoing traffic on the balancer and other networking equipments as well.

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 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 (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 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 Multiple Services Running On Load Balanced Servers

Jan 30, 2012

Our Exchange 2010 hub servers run multiple services/ports:  smtp, www, pop3,135, 143, https, 993, 995, 6001,6002,6003,60200,60201,8400, and 8402 what is the best way of balancing these servers so that if only one of the services failed on a server, it would switch only the failed service to remaining servers. At present I only use an smtp probe, so as log as that sevrice is running the server is marked good.

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.

9666 Port-Forwarding For Click N Load Remote Usage

Mar 17, 2013

I've got JDownloader running on my HTPC and access it via VNC.The problem with Click'n'Load (CNL) is, JD only listens on localhost:9666 for incoming traffic, and the browser applications only send traffic to localhost:9666, so I can't use CNL with the VNC connection.I have to redirect my PC's localhost:9666 to the HTPC's localhost:9666

I've read up on SSH tunnels, but failed to set one up to work. I also know this could be done with iptables, but don't know how. Do you know a solution to make a connection between both local 9666 Ports? Traffic would have to be redirected from the PC listening on localhost:9666 to the HTPC, making it available at localhost:9666 and vice versa.

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?
