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 have a requirement to select a farm based on source IP address. I tried creating a match all class-map that matches on the virtual-address and source address but I get this message.LB01/Admin(config-cmap)# match source-address x.x.x.75 255.255.255.255 Error: Only one match virtual-address is allowed in a match-all class-map and it cannot mix with any other match type To me this is the only place where it makes sense to set the source match criteria.
i have ACE 4710 appliance that terminate SSL and the connection to the servers is http.
The ACE (one Armed) is load balancing between two web servers and i am using stickness in order to take the connection on the same server based on cookie.I can access the website either by http or https., where on the web page there is a login credential to access using username and password.
When i access the website using https everything works fine and i can login to my account in https mode.When i access the website through http and login to my account the URL is redirected to https...normal because i am using action-list to rewrite the http into https. But when i exit the browser and access the website again using http it is not redirected to https(although i see that i am still login into my account i can see all the inforamtion in my account).
The customer wants the connection to be https even when i exit the browser and access the website again (within short time before the cookie exipres)
For a CSS with a SSL module (performing SSL termination) - is it possible to impliment a redirect on https URL to send to equivalent http URL.If my understanding is correct, the CSS will do SSL termination and then use an http content rule on the resultant http stream as it is recursively handled by the CSS ? This would mean that the SSL module has no way of seeing/acting on layer 5 and above data (i.e. picking up on a specific URL) and can not itself issue a redirect - i.e. you could not associate a redirect statement or service with the following ssl content rule ? [code]The CSS would instead rely on a http content rule to impliment a redirect - i.e. you would have to associate a redirect statement or service to the following http content rule instead?
But if the CSS is already handling traffic for existing url... traffic that is going to cause a loop when a client goes direct to. url...I realise the requirment is uncommon / a bit convoluted, its one of those don't ask type scenarios - aimed at achieving a specific requirement.Would the ACE 4710 be able to handle such a scenario any differently ?
I am trying to make a redirect from http to https. the goal is whenever a user writes in http://10.80.199.71 it should be redirected to https://10.80.199.71 I am just haveing some trouble making it work.
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....
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.
rserver host SRV01_123 ip address 192.168.1.101 inservice
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.
i have a 4710 appliance (one armed) and i am load balancing with two webservers. In the URL, there are links that need to be redirected to https:
i am using the
rserver redirect REDIRECT-TO-HTTPS[URL]
The https is working but i have a problem. when i access the Main link "first" it is redirected to https to the Main link.But if i access one of the Sublinks directly(without having to click on the main link first) the page is redirected to https but to the Main Link. i have to click the Sublink again in order to get the page.How can i redirect to https and stay on the same page? What might be the general link in the webserver-redirection?
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.
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.
I have Ace 4710 version A4.1.1 and I am experiencing interesting problem with GUI and SSH reachability. I am unable to connect to management vlan3000. Interesting is that I can ping from ACE to network but unable to ping or SSH or HTTPS to ACE. Everything seems good. ARP is ok, switch is OK, line is up, protocol is up. Management is enabled for icmp, https, ssh to any.
When I do show interface I noticed line Config download failures : 9.

I am configuring a load balancer from cisco, a ACE 4710.Load blancing is completely new to me, and i am unexpereinced in this field. It has to be configured for a customer that want to load balance HTTP and RTSP traffic over 4 application servers (Back-end),I searched alot on google for possible solutions, and got RTSP in some way to work, but http wont work says my customer.
I have two ACE-4710 in active/standby mode, running code A3(2.2). Four contexts are configured. Both devices were functional without problem, until I reload the standby unit. After reload, the standby unit completely lost its configuration with exception of the FT vlan and the FT peer configuration in the Admin context... Both units recognized each-other and I can still ping the primary unit on the FT vlan, but nothing else. Contexts are lost and interfaces are shutdown! Nothing changed at the software level, both devices run exactly the same image and the same licences are installed (it worked well before the reload).
So, I decided to reconfigure the basics on the standby unit in order to trigger a config sync from the primary. And here arrives the problem : I reconfigure the FT vlan, the FT peer, I check the peer state and everything is OK.
Then, I try to ping the primary unit from the standby unit with success :
switch/Admin# ping 192.168.16.1 Pinging 192.168.16.1 with timeout = 2, count = 5, size = 100 .... Response from 192.168.16.1 : seq 1 time 0.000 ms
I am looking at management (backup of the configuration) of the ACE 4710 running A4.1, the management software is Cisco Cirrus. The question I have is around the management of the context's, I have a backup of the Admin but would like the user context's also, how this is completed.
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?
When trying to view the status in the Monitor tab and the Config tab after you log in to the ACE 4710 Device Manager A5 (1.2) management GUI tool, I could not retrieve the status data and the following message appeared.
"Faild to upload Adimn configuration: There is error in loading configuration: Error in loading RMO config from DB:The given index XXXXXXXXX.bak does not match table index definition"
Other features include all normal, so I can get information by using the CLI.In addition, this configuration is redundant in the Primary / Secondary, this event occurs only on the Primary.
Other:-XXXXXXXXX.bak is a backup that you created in the checkpoint, and it does not already exist.
-When I'm logged on to the GUI, the above message is displayed in the status bar always.
-It was not recovered by ACE restart it.
-When I try to create the same configuration in a different environment, it did not reproduce.
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)

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
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 have an RDP server farm that lost a disk. The RDP service was still running but users were unable to log in. I'd like to create a health probe that does maybe a combination of TCP probe for port 3389 and something that can determine if the drive that stores user profiles is available.
I cannot add any new service (http or ftp) to the server. Is there any way I can check SNMP mibs on the windows server or maybe WMI through TCL?
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?
