is there a possibility to get a load balancing across two rservers so: when client sends http://vip/ and it goes to rserver1 then url is sent without change when client sends http://vip/ and it goes to rserver2 then url is modified to http://vip/xyz/
Or maybe load balancing can be done across two serverfarms ?
We are in the situation we have a active configuration with ACE30 doing normal load balancing in routed mode, we have tons of rservers going out on a VIP.we now had to add a new private network to a provider that strangely enough does not want to see our public or private addresses. we need to loadbalance towards him on a priovided subnet (still rfc1918) (IOS VRF bug? is that correct?)I have two options, add the network (new interface) to the active loadbalancers (contexts) and then tie in new policies to the active serverfarms or make a new context just to load balance towards this provider.(preferred)Now - If I do this, the rservers see the client source addresses from this new provider. as the loadbalancer does not "hide" the client IP's. I would then have to add static routers toward the new context - I would want to skip that.
is there a way, to make the loadbalancer hide the client addresses towards the rservers ? perhaps I'm just needing the correct search term to find the config example.
I'm configuring ACE 4710's for the first time and I want to load balance my Nuance speech servers on port 554. Here's my configuration on ACE01:
[code].....
I saw a strange beaviour in the ACE30 today.We are configuring most of our VIP:s with "loadbalance vip icmp-reply active" and I haven't thought about it that much.I just assumed it would do what the command says.Today an Intel tech called and said that he had taken down the webservice on port 80 on both servers in a serverfarm and he could still ping the VIP.I had a look in the ACE and saw that the VIP was marked OUTOFSERVICE. But he could still ping it at that moment.What is the criteria for the VIP not to respond to ping with the above command set?

I have a problem with the ACE 20 load balance
To start with following is our architectural request flow:
Load Balancer --> Webseal /(reverse proxy) --> HTTP Server --> Portal Server
We have Hardware Load Balancer Cisco ACE20. When we access our portal from Webseal server it works totally fine without any issue, but when we access the same application using ACE we face the following issues:
1) Some of the links on do not work. For eg: We have a link "subscribe" which points to [URL], whenever we click on this link, the request is directed to [URL] i.e homepage
2) URL redirection does not work We have some links which have a url forwarding or redirection for example when we open [URL] it forwards the requests to [URL] opendocument....., but this redirection fails and again the request is thrown to homepage i.e., [URL]
3) The response of the request and the overall portal when accessed via ACE is very sluggish and it takes 20 seconds for homepage to load, whereas the homepage loads in 4 secs when accessed via webseal.
Below is the ACE details.
Hardware Product Number: ACE20-MOD-K9 Card Index: 207 Hardware Rev: 2.3 Feature Bits: 0000 0002 Slot No. : 7 Type: ACE

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.
View 2 Replies View RelatedWe have a pair of CSS 11501,Currently it is using source ip for load balancing and 5 servers as backend , however we have users loggin in using http and based on its source IP (ISP PROXY) , it is forwarded to SERVER A.However, we have a SSL page and when the client switches over to SSL , it is forwarded to SERVER B/C/D/E based on its source IP ( REAL CLIENT IP) .This will cause the user to be terminated as the 5 servers are independent and not running in a cluster.
Is there any way that we can use the X-Forwarded-For address to load balance so that when users loging , they are sent to SERVER A (Based on X-Forwarded-For Header IP which translate to REAL CLIENT IP).This way we are able to also send it back to the same server when it uses SSL.I believe that we should be able to load balance using X-Forwarded-For IP or to rewrite the X-Forwarded-For IP into client source IP.
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 ?
View 4 Replies View RelatedI'm trying to design a CSS configuration that allows servers in the same vlan to be the source and destination of load-balanced traffic. My thought is to add two new vlans, one for the VIPs and one for the servers, then NAT the source IPs going from the LB to the servers.
Is this the right way to do it?I've never NATted using CSSs, so I wanted to verify what I'm thinking.Our current config trunks the vlans -
interface 1/1
trunk
vlan 1

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.

Is it all possible to use an ACE30 to RHI a VIP which acts as route for servers on LAN A to reach LAN B . We have 2xL2 WAN circuits between 2 sites used by only 4 servers for (different L3 subnets for the hosts). I`m considering using a VIP to load balance across 2 WAN circuits using L3 interfaces on the MSFC either side as rservers with a single VLAN in/out on the ACE where the VIP resides - simlair to using the Cisco design for firewall load balancing minus the inspections etc. Obviously we can do this entirely in the MSFC but considering options.

View 1 Replies View RelatedI have four rservers. I have found that if the first listed server in my serverfarm is off line, the entire farm quits working. How did I come to this conclusion? You see as part of "serverfarm host PORTAL-FARM" rservers "SISPOAS1 through 4". I can shut down any server except SISPOAS1 and all is well. The load balancer sees the probes have failed to that given server and continuses to load balance to the others. However, If I shut down SISPOAS1, nothing works. I confirmed this by eliminating SISPOAS1 from the configuration completely. After doing so, I could reproduce the exact same problem using SISPOAS2 since it is now the first rserver in the list after I removed SISPOAS1. I'm stumped! Looking at the configuration below, what am I missing???

Am looking to upgrade the software on the ACE30 from: [code]. Any ACE30 guide that explains this. Have looked at the ACE30 configuration guide which I thought would cover this in the section "Managing The ACE Software", however everything else has been covered off except how to go about upgrading the software.
View 1 Replies View RelatedI have a strange behaviour with some ACE30 running A5 release :
Setup is in bridge mode, working correctly with a default gateway set in the context.
For some reason, some return traffic is being routed on the ACE instead of being bridged.
On what conditions would the ace decide to route the traffic of simply bridge it from the server vlan to the client vlan.
After upgrade from ACE20 with A2(3.5) to ACE30 with A5(1.2) I get failures in a number of server farm's, where before upgrade the number was zero. No drops in VIP and logs from applications do not notice any new errors.

Last month I was reviewing following Cisco document, in which Cisco mentioned that ""To avoid possible memory fragmentation in the forwarding information base (FIB), Cisco recommends that the switch processor (SP) DRAM to a minimum of 1 GB ""

Since this document has been revised in Oct 2011 and, I can't no more find the above memory recommendations.
I want know if any one using WS-SUP720-3B with IOS SXI6 and Cisco ACE30 has gone for upgrading the SP DRAM from 512MB(default) to 1GB ?
I need to upgrade a pair of ACE30s to 8Gbps.According to the administration guide, there will be no impact.BUT, it states also:
All license installations except one have no adverse impact to an operating ACE. [URL] Ofcourse, nothing is said about which one has impact.I assume it's the 16Gbps license but how to confirm this?
