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?

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?
View 2 Replies View RelatedI 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:
PSTN SIP Providor >(router)> ACE4710 > sip_server(s) > ACE4710 > (router) >SIP Phone
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.
Configuration :---
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

Is there a way to rename a server farm, health probe, real server or virtual service without having to completely rebuild it? I'm running 3.0(A3).

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?

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?

View 3 Replies View RelatedI 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.
View 4 Replies View RelatedCurrently migrating from a CSS to a new ACE for all our inbound ssl connections.
On the CSS, I could define multiple backend services, different tcp ports and 1 IP.
ex.
service TEST_HTTP22
protocol tcp

But now I have to define each backend web server as an RSERVER and it doesnt allow me to configure 2 rservers with same IP.
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.

View 2 Replies View RelatedI had a working server running ISE version 1.1.0.665 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:
Router 1 - 74.92.X.X ---> NAT ---> 192.168.1.100
Router 2 - 67.78.X.X ---> NAT ---> 192.168.1.100
Router 3 - 97.76.X.X ---> NAT ---> 192.168.1.100
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.
