All clients point to unique VIP and Port configured, I need to know if I can apply any filter or rule that allows me to distinguish when a customer goes to the URL1 or URL2.If any client try to access to URL-2, your traffic must be deny.In summary, from Internet I should be able to go only to URL-1.
I have a problem, recently I can not telnet to the ACE 4710, the ACE version is A4(2.0). I can enter by web and console but not for telnet. I try to give more resource to the admin context but it doesnt work.
We have a rather strange issue, and I'm not sure it's really a problem with the ACE or not. We created an HTTP parameter map called "TCPreuse" and applied it to a virtual server. A show conn detail displays "[ conn in reuse pool : FALSE]" for all connections pertaining to this virtual server. The rserver in question is Linux(Ubuntu) + Apache.Next we applied the HTTP parameter map to another virtual server - this time IIS7 + Windows Server 2008. There are plenty of entries "[ conn in reuse pool : TRUE ]" when I do a "show conn detail".What could the web servers be doing differently that would cause the connection reuse to work on one virtual server and not the other?
I need to upgrade 2 active-standby cisco ACE4710, the issue is I cannot access FTP/TFTP/SFTP server via Admin context but can be accessible via other contexts.
Can I copy the ACE system software file from FTP/SFTP/TFTP server to image: directory durectly or need some other way around ? I could see the option is available to copy ftp: to image: via other context.
My customer they do not want change their real server IPs. So I need setup one interace (one armed) for them on ACE4710. Who had this sample configuration? (CSS has this but it seems to be not compitable with ACE)
I am attempting to configure an ACE4710 to perform SSL end-to-end confguration. i.e. SSL termination - load balance - SSL initiate to backend server.The configuration appears to work fine in a test lab using any old web server, however when I peform the same configuration in the production environment it does not work. It appeatrs from a capture run on the ace that the ace is reseting the tcp connections after communicating with the back end server. The main difference I can think of in this environment is that the cert and key pair the ace is using where exported from the backend server, i.e. both the ace and the backend server have the same certificates and keys. Is this allowed? how to troubleshoot why the ace resets the connection.
I have to deploy the Cisco GSS in our 2 dataceters globally seprate IP ranges to loadbalance the exchange 2010 environment with Cisco ACE 4710 series SLBs. The scenario is to deploy one GSS + ACE on each datacenters and our nameserver will point to both GSS's IP addresses to get through. Incase primary site "site A" goes down name server will point the client's request to "site B".
What will be the physical setup of the GSS here and what configuration should on SLB ACE will make it work? Do GSS and ACE need to be in the same vlan? is this necessary to use Both interface of the GSS to get things working? How the GSS will check the health check on ACE if they both are on different vlans/ip range? Our ACE will be in routed mode do we need to assign the Real server default gateway as ACE inside interface with the server farm or just do the SNAT of the client IPs so the request can come back to ACE?
I have HA configuration for two ACE4710. FT between Ace's is configured as L2 (V LAN). Active ACE is sending heartbeats, but switch shows lot of 'input errors' on ingress and this is a major problem. FT is logically not working (there is no connection between these two Ace's over V LAN). There is only L2 configuration, with speed and duplex auto, no other special configuration. When I connect Ace's directly, FT is working without problem.
I can see lot of errors on input direction (from ACE) to switch port, that means, L1, or L2 problem, but direct connection (using the same Ethernet cable) is working. I tried 'shut/no shut' on both sides, set duplex/speed,... without success.
Do you know if it is possible in ACE 4710 appliance to configure a SIP TLS ?The SIP probe we have in the configuration guide it is only for clear text. for Lync 2013 we need to establish first a TLS session and then within it, send an SIP request..IS it possible in any version? I tried also to configure a HTTPS probe but it fails as it sends a GET which the Lync SIP server doesn't understand.
ACE 4710 deployment model. We'll be doing an eval later in the year, but I'm just looking to understand the architecture.We have a stack of 3750 switches with a single VLAN (10.1.1.0/24). Connected to that stack is a pair of web servers (10.1.1.5 and 6) that we want to provide load balancing/failover for. Some of the clients are located right there on that same VLAN. Other clients may be coming from other spots in the infrastructure.It sounds like I could put a pair of 4710s connected to that stack of switches, in a single arm deployment? And then the virtual IP and the real servers would all be 10.1.1.0/24. Maybe use an etherchanel to connect each 4710 to two 3750s?
I'm implementing and found out some issues are unresolvable on ACE4710. This network have been running on a server without LB. Now the second server comes up. We choosed to implement with Routed Mode.This network Peak @ 300Mbps. Now on we're doing the first context which is function as content web-farm. In near future, 2nd context which takes care of indexing web-farm when they buy more server.
From following diagrams.I browsed from internet into this service. "show service-policy" shown as '0' (counter was not running). I guessed that there is something wrong in FW configuration. So I isolated out FW. Then I plugged-in my PC into network 30 (192.168.30.X) in front of this LB, then browsed into LB's VIP (192.168.30.1). LB "show service-policy" came up BUT there is nothing return to my PC (client). "show conn" on LB as "SYNSEEN". What's SYNSEEN?! Some meaningful.
Then I tried to figure out with a PC running 'apache' and took the place of real server. "It works!" returned from LB/Server. "show conn" became 'Establish' Programmer guy said if I browse into web-farm (i.e. content web-farm) directly pkt will be redirected to indexing server. But they said it will be L7 redirection. Not LB/Network level.
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?
On my ACE4710s I'm using least-loaded predictors monitoring Microsoft Windows CPU usage. There are times when the MS Windows CPU OIDs can change between reboots. Any way for the ACE to automatically adjust to the new CPU OIDs and continue to get accurate CPU usage values?
one of our 2 ACE boxes in FT group suddenly reboot-ed from active state and now it continuously reboots with the following error:
insmod: error inserting '/isan/bin/klm_octeon_device.klm': -1 No such deviceerror inserting /isan/bin/klm_octeon_device.klmDaughter Card Not Found. Rebooting..INIT: Sending all processes the TERM signal...
We have a CSS11503 that is currently being used to accept incoming HTTPS and SSH connections on a specific VIP and then PAT those client connections. I understand that it also PATs the server initiated connections. [code]
For server load balancing, does the ACE4710 support custom protocols? We'll be using HTTP for server health monitoring, and to determine if a server is up or down. But the client/server application is custom, and includes a lot of non-standard ports. Can the server VIP handle generic TCP connections? For example client1 connects to the VIP on http, but then later client1 switches to using tcp842 (a custom protocol, not http).
I have a ACE4710 setup to load balance a couple of web servers. The real servers all show as inservice as do the propbes and serverfarms/virtual servers. If I ping the Virtuual server ip address I get a reply but it I try to access VIP via telnet or web browser. I get a connection could not be open error on the client.The question is how do i determine where the error is comming from so far I can not tell if the client is getting through the acl or not.I have used the trouble shooting guide and nothing has worked to determine the cause so far. show service-policy int479 detail does not show an increase in the hit count when I try to connect.show stats conn does not show an increase in failed or timed out connections when i try to connect. [code]
My customer wants each ACE4710 (of a highly available cluster) to have its own, dedicated port for management purposes.
According to documentation, IP addressing can be applied to VLAN interfaces, so in order to satisfy the requirement, I should make one port belong to an "access VLAN X", and then apply IP addressing to the corresponding "interface VLAN X". This should satisfy my customer´s requirement in an indirect way.
But... ¿ Can´t I just configure IP address on one of the 4 ethernet ports in order to save the work of building the aforementioned VLAN? I am asking this since I do not have access to a real box in order to verify.
I was trying to implement stickiness based on cookie. Server inserts a cookie and sends it to the browser. I learned from app team that this cookie is changing dynamically during the session, so stickiness based on server’s cookie doesn’t work.
Now I want to investigate into possibility of ACE to insert a cookie. My question is: ACE feature of “cookie insert”: does it add additional cookie into http header without removing server cookies or it deletes the cookie(s) that server put into http header and replaces them with its own cookie?
We have an ACE Appliance in a DMZ and the ACE Appliance's Admin Context IP is translated between ACE and ANM. The ANM Server does not get translated. It is just the opposite then in another Community discussion.
Our Problem: When adding the ACE4710 Appliance to the ANM imported Device List, we use the ACE's NATed Admin Context IP. Import works well, but ANM reflects the Admin Context IP with it's real configured IP. Polling the ACE Appliance does not work therefore.
Is there a possibility of telling the ANM, that the ACE has to be polled through a NATed IP? I could not find a field to set a NATed Mgmt IP.
Configured IP on ACE Admin Context: 192.168.0.10 NATed ACE Admin Context IP: 172.16.0.10
Imported ACE with IP 172.16.0.10 into ANM, but ANM polls for Rserver, Vserver, Probes, etc. via 192.168.0.10 - which is not reachable from the ANM.
I am having two sites, at one site the ISP is terminated on 2900 Router and at one site ISP is terminated on 3500 L3 Switch. Now need to configure the IP SLA on this. In the current setup I am having two 2900 routers at one location and 3500 L3 switches which by point to point link.
I have a problem configuring URL redirect on ACE 30 (Version A4(1.0)).When a user enters IP address or a name of a service [URL], the ACE module should redirect him to the page [URL]. Here is my non-working config:
access-list OUTSIDE line 8 extended permit tcp any any eq https access-list OUTSIDE line 16 extended permit tcp any any eq www access-list OUTSIDE line 24 extended permit icmp any any probe http Test_HTTP_1 port 80 interval 60 passdetect interval 30 passdetect count 2 request method head url /index.html expect status 200 200 open 1 rserver redirect URL_Redirect_01 webhost-redirection [URL] 302 inservicerserver host S1 ip address 10.0.0.2 inservicerserver host S2 ip address 10.0.0.3
it works, ACE load balances to rservers. Of course, user must enter full url.With redirection configured, user recieves HTTP url redirect message with correct address [URL], but his browser does not display the page. Even directly entered full url does not display it while redirection is configured.Alternatively, does ACE30 already support url rewrite?
We are deploying a Microsoft Exchange 2010 server environment, which will have a ACE 4710 front end. What we are finding is that if a server goes down, a client will need to re-authenticate to a new server. The server team has informed me that if they use Microsoft SLB this does not happen. They have also mentioned that we are getting basic authentication, rather than NTLM. As a result I have read several posts/articles which mention forcing NTLM on the ACE, but none go into real detail.
A couple of official Cisco documents point to having the Exchange Server, and Client both set to use NTLM. So on the server you do not need to select MAPI encryption. I am told this is not an option here, because a multitude of clients are supported, from Outlook 2003, through to 2010.
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.
Im trying to configure an ACE 4700 so that SSL termination is done on the ACE and HTTP reaches the weblogic server instance. I have a working setup of a Apache reverse proxy doing SSL offloading and using a weblogic module and that works fine Was reading [URL]. Any working config example for doing this with the ACE4700
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 ?
We are using an ACE20 module running version A2(3.2).I have a question regarding IP stickyness and the timeout parameter.I found this in the "Server load balancing configuration guide" (in a section entitled: "Configuring a Timeout for IP Address Stickiness"):
"The sticky timeout specifies the period of time that the ACE keeps (if possible) the IP address sticky information for a client connection in the sticky table after the latest client connection terminates. The ACE resets the sticky timer for a specific sticky-table entry each time that the module opens a new connection or receives a new HTTP GET on an existing connection that matches that entry."
The parts in bold seem to point to the fact that the timeout is an "inactivity timeout" as the counter is reset on every new connection.The next section in the documentation is entitled: "Enabling an IP Address Sticky Timeout to Override Active Connections" and says:
"By default, the ACE ages out a sticky table entry when the timeout for that entry expires and no active connections matching that entry exist. To specify that the ACE time out IP address sticky table entries even if active connections exist after the sticky timer expires, use the timeout activeconns command."
This seems to contradict the previous statement.So my question is: is the IP stickyness timeout an "inactivity timeout" or not?
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.
