Cisco Application :: Insert X-Forward Header In ACE 4710?
May 5, 2013
We are using Cisco ACE 4710 to load balance servers. We have created VIP under the interface vlan using nat-pool command. Also, we have changed the gateway of the server to point to the ACE vlan ip address which is created using alias 10.x.x.x 255.x.x.x command under the interface vlan. In short ACE is in inline mode for the servers which needs to be load balanced.
[code]...
But still I am not able to view the original client IP. Just to add more, the site is a HTTPS site & we have not doing any kind of SSL offloading on the ACE, it is taken care by server itself
I just want to do the HTTP & HTTPS load balancing without SSL offloading & should be able to see the original client IP in the server logs
I have an ACE version A5.2 configured in one-armed leg (doing source nat). I have a requirement to add(or copy) the "referer" header value from the original request to the request send by ACE.
I cannot figure out how to copy this value. It is easy to add the source ip address by adding: " insert-http x-forwarded-for header-value "%is".
So how I am going to copy the Refere header?
#Referer #Address (URI) of the resource from which the URI in the request was obtained
We are migrating from ACE 20 module to an ACE 4710 appliance. [code] When pasting in the config on the ACE 4710 running A4(2.1) code, I get the subject error message when trying to enter in the highlighted sticky-serverfarm command above. Again, this config works on the older hardware and older code.
We are using an ACE engine module(ACE20-MOD-K9) provide loading balancing service for two WEB servers and configured cookie for stickness. Below is the current configuration and it seems working fine now.
The problem I was facing is before use parameter-map change the http header length to 8k the stickness doesn't really working properly. User complains that their working session constantly be kicked out and redirect them to login page. By tracing traffic from a client we found that sometime ACE fails or stop insert the configured cookie, after increase the header length ACE start getting work.
how does the header length setup effect ACE to insert a cookie? Will the cookie insert attmpt fail if the header is longer then the maximum length configured on ACE? [code]
I created several rules to balance on a specific server somes apps. Everythings works great in http but no in https.In my example, i would like [URL] to be redirected to my server2 but it's always using the default rules instead of the L7CLASSSrv2. Today [URL] is well redirected. All other apps are correctly loadbalance with the stickyness effect but I can't handle the https connections.
class-map match-all L4-WEB-IP 2 match virtual-address xxxx tcp eq www class-map match-all L4-WEBHTTPS-IP 2 match virtual-address xxxx tcp eq https class-map type http loadbalance match-any L7CLASSSrv1
Is there a way to convert TCP options header into an http header using Cisco ACE ? is there an equivalent solution with Cisco as the one proposed by F5 here: url.
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?
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'm looking for a recommendation for a setup guide including ft i've had a quick look a wiki and i can get basics but i'm not sure about if i need to setup additional contexts etc when i'm the only one using the appliance?
I have an issue with a customer that wants to update a server behind the ACE. The problem is that when the application wants to update the server it does it with the name.Doing some research I found that you can rewrite the record DNS based on the static NAT you set up on the ACE. The feature is called DNS inspection. Is the same feature as the ASA (DNS doctoring).I apply it to the outside interface and it did not work.
I am trying to configure sticky on an ACE 4710 and don't understand what the netmask part of the sticky ip-netmask netmask address {source | destination | both } name command.
Some examples use 255.255.255.255 and others use 255.255.255.0 but I don't know what the significance is or what it does?
I am going to configure for both source IP and destination IP (both).
With the current (A5) ACE 4710 lic setup, does the "X gigabit per second appliance throughput" that is licensed affect: -
A) Only "appliance" i.e. load balancing traffic, any other normal routed traffic is not included in the limit
or
B) Is it an overall throughput limit on the interfaces i.e. includes all traffic not only load balancing traffic but also normal routed traffic crossing the appliance
Looking at a scenario where the lic size I need for HTTP load balanacing would be one size if A) but would need to be much larger is B) to accomodate out of hours routed backup traffic crossing the ACE 4710
I've got a web app that the owners want to run over port 80, but also using SSL to secure private data in transit. The architecture is an ACE 4710 in SSL termination mode->Apache (port 2000)->Back-End app server.
I've got two VIPs set up already - one on port 443 and one on 2000 - both of which do the SSL termination quite nicely, but using the 3rd VIP set up on port 80, the connection steadfastly refuses to be HTTPS (i.e. doesn't show the padlock).
I've done all the set-up through the web interface so far, can this be done? If so, how?
I am currently running A3(2.6) and evaluate the possibility of upgrading to A4(2.1). The Instal & Upgrade Guide A4(2.0) mentions that A4(2.0) does not include all features of A4(1.1). Does this apply to A4(2.1)? The Release Notes mentions a list of features merged from A4(1.1) to A4(2.1) but does not clarify if there any features not merged.
we configued An ACE 4710 with SSL termination on Oracle Aplication Server 10g (10.1.2.0.2) ,so that SSL termination is done on the ACE and HTTP reaches the Oracle Aplication Server 10g (10.1.2.0.2) then we configure the ACE to enabled client authentication with Pkcs#11 smart card token certificate and this don succfully my problem need do this client certificate authentication for only the [URL] not for all SSL proxy service how can do that.
I'm receiving a lot of these messages in a ACE4710 cluster. 192.168.100.1:80 is the VIP, 193.126.127.28:56380 is the client. Already tried to set the mss with this:
parameter-map type connection my map set tcp mss min 0 max 1380
policy-map multi-match L4_policymap class vip_PRDWEB_http loadbalance vip inservice [code].....
We have recently transitioned one of our Ecommerce products to a new data center, at which we now use a one-armed load balancing approach rather then the routed load balancing approach we used previously. This is casuing us some issues as we generally log the source IP address a user comes in on when he fills out an application. Now the logs only show the natted ip address recieved by the load balancer, which does us no good. Any way to log the source IP address when a new connection is created to a particular vip?
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 am new to the 4710 appliance.Apart from the 4 GE 'data' ports, there are 2 Ethernet 'management' ("console") ports. I find the description in the "quick start guide"somewhat confusing. URL, Is a first-time serial connection (at least to run the initial config. script) mandatory? Or can you obtain the same result via one of the 2 Ethernet management ports and using a default ip address (192.168.1.10 ? When running the initial config. script (only possible from the serially connected console i suppose), you have to select your management port. Why does the system in step 5 proposes you 4 ports, and not just 2? I suppose the intended port for management is one of the 2 management ports, not one of the 4 data ports?
I have a pair of ACE 4710s with 12 contexts sharing the load, running A4(2.1). esterday I upgraded one of them to A4(2.3) now I cannot telnet to the Admin context.Pings ok. I can telnet to other contexts on the box and everything seems to be working ok when i do a " sh telnet" comes back with
No Session Information is available sh telnet maxsessions telnet maxsessions 16
ACE# sh script code NORDICID_PROBE.Error: Called API is invalid or non-existant.Hardware is ACE-4710-K9 and software A3(2.7)The probe itself is functioning ok according to show probe detail.However show script script_name probe_name -counters all remain at zero for some reason. This wasn't the case on the previously use ACE software.To my recollection the command show script code has worked successfully before on the same ACE software. Not 100% sure though, but it definitely worked on the previous software we ran on the ACE.
Any document that details the steps to change the FT ip addresses of a pair of Cisco 4710 whilst they are running in a production environment without causing an outage?
Would the steps be: On the secondary unit: hbs-syd04-lb01ft interface vlan 417 ip address 172.30.254.221 255.255.255.252 peer ip address 172.30.254.222 255.255.255.252
Then on the primary unit: hbs-syd04-lb01ft interface vlan 417 ip address 172.30.254.221 255.255.255.252 peer ip address 172.30.254.222 255.255.255.252
I have a pair of ACE 4710's running software version A3(2.0). I intend to upgrade to version A5(1.2). Can I go straight to version 5 or do I need to go to version 4 and then version 5?
We have two pairs of ACE 4710s, one pair running A3(2.4) and the other pair A3(2.0). We plan to upgarde the second pair so that they are running the same image as the first pair (we know they are not the latest, but this is the first step in a larger rollout plan, and to aid some troublshooting for a major issue we are seeing.)
I have details of the upgrade steps, but my question is with regards to the licenses which are now enforced after (2.0). We currently have the following on the first pair, but are these part of the default licenses for (2.4) or would we need to purchase these as well?
I need to use the Ace 4710 to distribute a Proxy PAC file, e.g. [URL] which will be configured in client browser using an AD group policy. Is it possible for the ACE to host and serve a file in this way?
Can the Nat Pool be on a different network that the load balanced vip? My current design uses nat pool on the same network, but the archatect wants the NATs on seperate VLAN.I will be developing on ACE MOD20, but the final configuration will be on 4710.
I configured ACE 4710 for HTTP traffic. All applications are running through real server. But when I run the same applications from virtual IP i.e through ACE. some applications are not running. Particularly applications having XML.
Is it ACE issue or Application issue. If it is ACE issue then how to troubleshot.
