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?

I am trying to configure ACE 4710 to load balance base on the URL, If it matches the specific URL ( /456/ ), the traffic will be sent to server farm 456 else the traffic will be sent to server farm 123.
I attached an image of the topology.
Ace Config:
rserver host SRV01_123
ip address 192.168.1.101

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.

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?

I have been tasked to provide SSL(HTTPS) access to a server farm that will be accessible from the internet. Is this the correct guide to follow?

I am assuming I will need to purchase a certificate to import into the load-balance r as well.

I have a Cisco ACE with a server farm "intranet" with real servers rsrv1 and rsrv2 (round robin) and i have two sites A (IP Address A) and B (IP Address B) in the WAN. I want to that Site A conect to ACE 4710 via VIP, but this connection will be to srv1 and Site B conect to ACE 4710 via VIP, but this connection will be to srv2.

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)

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 ?

i have a 4710 appliance (one armed) and i am load balancing with two webservers. In the URL, there are links that need to be redirected to https:
[URL]
i am using the
rserver redirect REDIRECT-TO-HTTPS[URL]
The https is working but i have a problem. when i access the Main link "first" it is redirected to https to the Main link.But if i access one of the Sublinks directly(without having to click on the main link first) the page is redirected to https but to the Main Link. i have to click the Sublink again in order to get the page.How can i redirect to https and stay on the same page? What might be the general link in the webserver-redirection?

I have been experiencing some issue with a portchannel interface.I have two cisco switches 3560 and I have a portchannel between them ( It is composed by two gigabitethernet interfaces generating a portchannel of 2 Gigas ).Unfortunately, I am verifying that one interface traffics about 893MB but the other interface only traffics about 100MB.Is there any cause why is this happening? I thought that maybe both interfaces would traffic about 450MB.Is there some wrong configuration with the load-balance command?. At this moment there is no load-balance, It is only configured the port channel with the default configuration.

We have :DSLT-1 I want to route all VOIP traffic and traffic to one IP address over the T-1, all other traffic I want to route over the DSL. HOWEVER, in the event that the DSL fails, have the DSL traffic failover to the T-1.I have setup the router to do just that (I think) and when I go to a site like "whatismyipaddress.com", it shows my IP as comming from the T-1. With the setup I described that traffic should always route over the DSL.Straight up protocol binding won't work because the traffic I want to route over the T-1 to one specific IP is going to be prot 80 and 443 (web traffic)

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.

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.

We have two Cisco ACE 4710 and we want to install both of the devices in HA with load balancing mode.While i have done HA mode configuration between ACE 4710.But unable to configure load balancing configuration between them.i want to tell you connectivity between server,client & loadbalancer.Our Web servers are connected to VLAN 152 on the L3 (3750) switch.Which are alreday working in redundancy between other L3.And ACE 4710 it is also connected to vlan 150 which are connected to same L3 (3750) switches and users are also connected to vlan 6 on the same L3 itself.

I am installing a several new Cisco VM servers. The VM hosts are losing connectivity when we apply the etherchannel config in the core stack. VMware has stated that the etherchannel load balance needs to be src-dst-ip in order for the etherchannel to work.However, my current stack has 2 etherchannels configured to other switches through out the bldg in network closets. The current load balance configuration is src-mac.My question....when I make the change to src-dst-ip, will my network connectivity go down? I saw there was an older article on this that doesnt provide an answer just a work around. Here is the article. [URL].

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 ?

At present I only use an smtp probe, so as log as that sevrice is running the server is marked good.

I have two ACE-4710 in active/standby mode, running code A3(2.2). Four contexts are configured. Both devices were functional without problem, until I reload the standby unit. After reload, the standby unit completely lost its configuration with exception of the FT vlan and the FT peer configuration in the Admin context... Both units recognized each-other and I can still ping the primary unit on the FT vlan, but nothing else. Contexts are lost and interfaces are shutdown! Nothing changed at the software level, both devices run exactly the same image and the same licences are installed (it worked well before the reload).
So, I decided to reconfigure the basics on the standby unit in order to trigger a config sync from the primary. And here arrives the problem : I reconfigure the FT vlan, the FT peer, I check the peer state and everything is OK.
Then, I try to ping the primary unit from the standby unit with success :
switch/Admin# ping 192.168.16.1
Pinging 192.168.16.1 with timeout = 2, count = 5, size = 100 ....
Response from 192.168.16.1 : seq 1 time 0.000 ms

When trying to view the status in the Monitor tab and the Config tab after you log in to the ACE 4710 Device Manager A5 (1.2) management GUI tool, I could not retrieve the status data and the following message appeared.
"Faild to upload Adimn configuration: There is error in loading configuration: Error in loading RMO config from DB:The given index XXXXXXXXX.bak does not match table index definition"
Other features include all normal, so I can get information by using the CLI.In addition, this configuration is redundant in the Primary / Secondary, this event occurs only on the Primary.
Other:-XXXXXXXXX.bak is a backup that you created in the checkpoint, and it does not already exist.
-When I'm logged on to the GUI, the above message is displayed in the status bar always.
-It was not recovered by ACE restart it.
-When I try to create the same configuration in a different environment, it did not reproduce.
