Cisco Application :: ACE 4710 Server In Multiple Server Farms
Jul 23, 2012
I put multiple rservers in multiple server farms?
So for example rserver1 and rserver2 are put in serverfarm production1 and are in use with particular sticky and load balancing settings.
Can I then create serverfarm test_production and put both rserver1 and rserver2 in it? Then play around with the sticky and load balancing settings as a test without affecting the production serverfarm.
What are the maximum number of real servers, server farms and virtual servers i can configure on ACE30 module,Is there any documentation available on cisco site where i can check this? Does it depend on the hardware or does it depend on the software version?
If we use an ACE4710 to load balance two real servers, obviously it will use health checks to determine if a server is down.When it detects a server is down, it will not send it any more traffic.But can we also have it take any other action? For example maybe email an admin, or send an SNMP trap? Or better yet, can we use a custom TCL script to do other things, like launch some custom activities?
I have a Cisco ACE 4710 A5(1.2). Scenario: Inbound call from PSTN to SIP Phone. Call comes into the VIP and then load balances to sip server, the server then routes the call out via WAN to the SIP phone as below:
Note: Router is Cisco 3925 with "ip nat service sip udp port 5060" and Port 5060 mapped to the VIP of the ACE.If I put the sip server directly behind the router it works fine. From behind the ACE:
If I turn on sip inspect on the VIP the call setup (INVITE) and termination (BYE) work fine but the audio loops on the PSTN side from the mic to the speaker.If I turn OFF sip inspect then the audio is fine and mapped correctly but the call terminaton (SIP BYE) hits the VIP from the PSTN but never reaches the sip server.For ease and dianostics, I have turned off all sip servers except one meaning the load-balancer has only one server to choose from.SIP Call_id sticky is setup and seems to work, though irrelevent with one server only on test.How do I get the ACE to accept 'server initiated traffic' with sip inspect so it knows about the pending BYE when it comes back from the IP phone via the VIP?Config below, image attached. Bridged mode (also get the same result in routed mode)

configure Cisco Ace 4710 ?Note :- Just a testing face I need to access my one server(192.168.1.11 : 80) through VIP :- 10.13.77.10 , I have only one Cisco Router 2800 and One L2 Cisco Switch 2960 and Cisco Ace 4710 . So I already configured 2 Different VLANS in Switch (Vlan 10 & Vlan 100) and by router I given the ip address of that Vlans with Inter Routing Vlan. My Connectivity is like this :-- Router Ethernet 0/0 --- 10.13.77.1/24 with vlan 10) & Router Ethernet 0/1 ---- 192.168.1.1/24 with vlan 100 ) connected with switch after that I configured ACE LB and connect the ACE interface with switch Like that ---- Connect to ACE Interface 2/3 vlan10 with switch vlan10(Ethernet port 2-12) and Connect to ACE Interface 3/3 vlan100 with switch vlan100(Ethernet port 13-24) .Testing to access server from Switch Vlan10 to Vlan 100 where my server is there.
ACE> client side Vlan10 (10.13.77.4/24) , VIP :- 10.13.77.10, SM-- 255.255.255.255 ACE> server side Vlan100 (192.168.1.5/24), Web server -- 192.168.1.11 with 80 port ACE> Managment Vlan 1000 (172.16.6.5/24) , ip route 0.0.0.0 0.0.0.0 10.13.77.1
I already Configured in Routed mode but From Vlan10 ip subnet example like 10.13.77.12(Client or User PC) tried to access server 192.168.1.11 with VIP http://10.13.77.10 but not responding , if i access server with real IP then accessible (why boz there is inter vlan routing)?
Access Server through VIP (ACE 4710) but very slow
Accessing the server very slow.., check my real configuration... this configuration is for application server and after this i have to configure more serverfarm for different server like webmail etc. in this ACE 4710. I have only one ACE 4710 .
ACE Version A4(2.0) = is there supports Probe with this version? without probe server will work but very slow.
VIP :-- 172.16.15.8 LB/Admin# sh run Generating configuration....
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 recently installed a Cisco ACE 4710 version A4(2.0) into our test network. Load balancing across a number of web servers appears to be working ok and serving pages to users. However, when i tried to check the real time stats via device manager (Monitor> virtual contexts> context > Real servers) a number of fields specifically "current connections", "total conns", "failed conns" etc were showing N/A. Do I need to enable this somehow i.e. polling, if so how?
We are using a sticky serverfarm with 2 real servers, one server was down for maintenance for an extended period of time. When it came inservice again it was not getting any connections. is it because all the connections had stuck to the other server ? we want sessions to be sticky but we also want to LB?I got it working by bouncing the server that had been online all the time. things started to LB then.BTW the ACE 4710 is running 4.2.1
I ma having issues trying to import a .PEM file into an ACE 4710. The original file was a PCKS12 file that was converted to a set of .PEM files as I have no access to any server to do a file transfer. This has worked in the past. the error I get is "Error: File not of recognized types - PEM, DER or PKCS12, import failed". I am not sure what is exactly failing. The cert was converted to a .PEM and the ACE imported that fine.
Currently running an ACE 4710, which is handling all of our inbound SSL connections and then forwarding requests thru to backend web servers. This all works fine.
My question is this..Right now we are not load balancing any of the backen web servers. But I now have a requirement that should a web server crash or become unavailable I need to redirect that backend connection to another web server.
Scenario is more like I have 2 web servers both serving same content, but I want one server to take all the connections unless it fails, at that point have all the connections forwarded to 2nd server.Is there a way to setup the load balancing where the 1st server gets all the connections until a failure happens ?
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´m Trying to synchronize the clock with NTP server external, these ntp server only support NTP version 3.Can I change the NTP version in the ACE4710 Appliance to support the ntp server external?If is possible, How I can change it ?

I want to configure my ACE so that if a probe fails, it fails over to the backup rserver, BUT it won't failback to the primary rserver until manual intervention is complete. The problem is we don't want an rserver to fail and failover to secondary, then failback to primary, repeat... (flip-flopping). I want to be able to have time to get on the server and find out what may have caused the probes to fail before it fails back.
I'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 -
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.
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 want to learn how to make application server?I have Windows server 2008 enterprise edition and it is connected to 10 Client Machines. I want to install software programes only on server and use them on client machines without knowing server password.
We are currently running ANM server version 4.1. I am trying to upgrade to version 5.1. But when I run the "application upgrade anm-va-5.1.ova Upgrade" command, I receive an error that states: "Manifest file not found in the bundle".I then tried to run the install command with the same error.
I had a working server running ISE version 184.108.40.2065 but someone in the build room decided to pull the power out of the server rather than shutting it down correctly. I have booted the server back up however the web management page was not accessable. I have checked the server status and the end result is the Application Server in the "still initializing" stage. I have left the server for several hours and the status has not changed.
I know people have previously run into this issue but no one has posted any resolution or confirmed that a rebuild is the only solution. I have tried to create an on-demand backup but it seems to fail when attempting to provide the credentials (which are correct) for the FTP server.
I have a job with a budget-limited client who has three Cisco RV042 dual-WAN routers. They had hoped to establish rather seamless *inbound* service, which doesn't seem to be the real purpose for these units, they appear to be designed for bandwidth aggregation and/or rather seamless *outbound* service.Since they have three of these routers, and three broadband connections (two different 5 IP blocks at one ISP, one 5 IP block at a second ISP) I am toying with the idea of using one router per broadband, and configuring each router for One-to-One NAT, dispensing with the dual-WAN redundancy feature.Each router will come from a different public subnet, yet have a one-to-one NAT to the *same* internal server, for instance:
The routers will be configured on the same subnet internally. 192.168.1.1, 192.168.1.2, and 192.168.1.3 respectively. I'll use weighted multiple default gateways on the server's IP configuration, to establish their default and failover gateways.My question is, does configuring multiple routers for one-to-one NAT to the *same* server cause any conflict or failure? You know, of the "sorry bub that private interface is already sucked up by router 1 and I can't do this" nature?
We recently configured a setup to loadbalance 2 application server using ACE4710. Initially the configuration was to link two app servers directly to ACE4710 without connecting to a Switch, but later, it was advised that ACE4710 is not able to work without connecting to a switch.
1. ACE4710 is not able to link directly to APP/WEB server, but it must go through a network Switch.
2. If item-1 above is true. We used to have a older Cisco Loadbalancer which is able to link directly to WEB/APP servers. What is the reason or advantage of removing this feature?
I've been running into an issue with Cisco CSM for a number of years, but always found a way around it. Im attempting to get to the bottom of this to find out once and for all, if this is infact a limitation of the device, or a config issue/work around is possible.
Here is my situation. My CSM's are configured in bridging mode. Traffic works great, traffic bridges across vlans correctly. Everything works and have many instances of smilar configurations running in production. Every once and a while, a client requests that a "real" server (ie LWCMW-021) cannot ping its VIP address (10.95.88.68). I am assuming this is related to the NAT Server, but not 100% sure. Clients have requested this functionality for some type of application based purpose, but Im unaware if CSM in bridging mode can provide this or not.
real LWCMW-021 address 10.95.88.59 inservice ! real LWCMW-022 [Code]....
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.
I'm trying to set up a load balancer within an OVH (hoster) infrastrcture, I've followed their instructions [URL] I'm using a RIPE block (5.135.193.xxx/28) and would like the first 8(5.135.193.xxx/29) to be used as the virtual server.vlan 2676 is the local one, and vlan 1227 is the public one.After all the config steps, none of these IPs are responding to a ping, nor a direct http request.
the full configuration is :
