Cisco Application :: Maximum Number Of Real Servers And Server Farms In ACE30 Module
Jun 17, 2012
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?
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.
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.
we use ACE30 module, ver. A4(1.0) for access to intranet application. The https connection from client is terminated on ACE module, LB algorithm is used and new SSL connection is initiated to the server. Standard operation works without problems.
But when user generates a .xls od .pdf report in the application, it should open in a new popup window. Problem is, that it does not (but on the server, the report is generated and stored). The PC and browser are configured fine, when accessing the application from the same PC directly (bypassing the ACE module), the popup window appears.
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?
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 ?
I am trying to get documentation on how to integrate an ACE30 module in a service chassis design integrated with the Nexus 7000 in routed mode. Only documentation I could find shows this design with the ACE30 module in a one arm mode. Any documentation that shows this implementation of this design?
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.

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?
someone at work sent me an e-mail they claim was forwarded. I don't think it was, and I need to know before I ask, because accusing someone of making it look forwarded, I viewed the source code, but I can't tell, it was sent through a microsoft exchange server.I think they copied and pasted and changed dates, is there anyway to tell from the source code?
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.
I 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???

I am new to the ACE30. I a basic configuration from the CLI and I am trying to use the device manger. I am able to get to the web informational page rather then accessing the login page. I have rest the password for both the admin and www and still no go. my question is how to go into enabling the GUI access.
is it possible to construct the L7 HTTP class-map expression to match all URLs except one? I have 1 correct url, for example: /correcturl.* and want to redirect requests to all other possible URLs to this one, without the need to list them all in "possitive match" statements.

Notes:There is the primary subnet 184.108.40.206/26 and the secondary IP subnet 220.127.116.11/27?The nat-pool is configured to allow server initiated connections to their frontend VIP when necessary.We are noticing that when a server on the 18.104.22.168/27 subnet needs to communicate with a server on 22.214.171.124/26, albeit on the same VLAN, the destination server sees connections with a source IP of 172.16.25.231, which is the NAT address. Is this expected behavior, where connections between IP subnets, albeit on the same VLAN are NATed?

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.
I have a request to configure an ACE30 for Oracle Hyperion utilizing SSL termination at the SSL offloader(ACE30). Any sample configuration or template of some sort that could guide me through what needs to be configured. We have many applications on the ACE#) but this is the first time we are going to try SSL termination.
We currently have 6 admin context and they are all utilizing the same snmp engineid (Local SNMP engineID: 800000090441646D696E) which is causing issues as far as our monitoring/performance platform CA eHealth. Isn't the engineID, by default, the first interface on the device?
Doesn't seem to be the case on an ACE30.How is the SNMP engineID derived on the ACE30?
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`ve seen quite a lot of posts regarding SSH issues and the above SSH error. However the fix mainly involves upgrading clients but in this instance the client is are Cisco routers 3845 / 2811 - which we use for out and inband management.Connectivity / routing etc is proven. Using SSH v2 the actual 6500 chassis where the ACE is physically located works fine. Configuring SSH v1 on the ACE module allows connections via the 3845/2811`s but we cannot use this.Both have the following IOS Version 12.4(24)T4. I have tried various key sizes on the ACE module.
