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.

We have a ACE 4710 with a basic config, When clicking on a tab from a window within Interent explorer we occasionally get an issue with it returning: "Internet Explorer cannot display the webpage" The details show "Access is denied" accessing a particular line of a java script file.
We have put one web server out of service in the farm to make sure that this isn't a result of stickyness not quite working. We have tested extensively by going directly to the web server directly without the load balancer and cannot reproduce the problem but we can produce the issue within a few minutes when going to the load balanced address.

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.

Can an ACE 4710 have , in the same context - servers which are
a. just being routed to
b. a set of load-shared servers
I have been told you may not be able to do this on this version?

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 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 ?

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?

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.

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.

Report run via Individual Web server URL’sThe report takes less than 20 minutes (average 15 minutes) to fetch and return the data. This is observed 9 out of 10 times.Report run via ACE Load Balanced URLThe report keeps on running for more than 20 minutes and never completes. The front end keeps showing report is running.The data in general when tested directly by running queries against the database (bypassing the platform) completes in 15-18 minutesThe network connectivity for each and every ports involved (Loadbalancer/Servers) have been throulgly checked.

I did nothing different to my computer. It was online fine and then an hour later when I came back, it wouldn't load any pages. I have a DSL modem and a wireless router that also connects another family member's desktop to the Internet. (As well as our phones via wifi.). The connection is fine on the other PC through a wireless adapter (both are desktops), and on the wifi the phones work perfectly so I know the modem and router aren't the problem. But even though my desktop says it's connected (not wirelessly, it directly connects to the router.), no pages will load. If I use chrome browser it eventually tells me this webpage is not available regardless of which page I try to load, or sometimes it's telling me no data received - unable to load the webpage because the server sent no data. Yet oddly a couple of times after forever it seemed to half load a couple pages. Internet Explorer just keeps trying to load pages forever with blank white page as a result.

I'm currently using a Belkin F5D8233 wireless router and an HP DV6 laptop. My internet used to work just fine, but after I reinstalled my OS a couple of months ago I started having a funny problem. My internet will randomly stop working, I'll visit facebook, check a blog, and then i'll try to check my email and the page won't load. Then my internet won't work again until I reset my computer. The weirdest part is that Windows acts there's nothing the matter. The little icon in the notification bar still says it's connected and if I click repair, windows tells me there's nothing to repair. My wife has a different laptop and she's still able to access the internet fine after I've been kicked off. I've checked for a router firmware update and it's up to date. I bought a usb wireless-n adapter thinking my laptop's adapter might be bad and that didn't work. I considering buying a new router, but I'm not confident that will solve the problem since my wife's internet is still fine and because my internet works again when I reset, so it's not like the router is blocking my IP right?

I own a wireless WRT54G, which has worked fine in the past. After setting up a new wireless network, I went to the router webpage to open some ports. The problem with the page loading is that it doesn't display correctly. No clickable text is displayed on the top of the page or the side bar, so I basically can't do anything whatsoever to configure it. I've tried loading it up in both Firefox and Internet Explorer, with IE saying the page loaded but with errors.

I've just recently upgraded a Cisco 877 to 887W router.
I basically copied most of the config across to the router with no problem.
ppp chap hostname and password all ok. ATM and Dialer1 interface comes up.
The problem I'm having is when I open Internet Explorer up, default homepage is Google. Google loads up fine, type a search is fine but when you click on the link or type URL, for example BBC News or Sky Sports, it takes a long time to load or times out (Page cannot be displayed)
DNS servers configured on Cisco router are: 8.8.8.8 and Virgin's DNS servers.
NSLOOKUP in cmd prompt it returns IP add no problem. however in web browser it fails except for Google.
However, with the same config on a 877 everything works perfectly...
Cisco 877 running 12.4
Cisco 887 running 15.0

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.

I am trying to configure sticky on an ACE 4710 and don't understand what the netmask part of the sticky ip-netmask netmask address {source | destination | both } name command.
Some examples use 255.255.255.255 and others use 255.255.255.0 but I don't know what the significance is or what it does?
I am going to configure for both source IP and destination IP (both).

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

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?

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.
