Cisco ACE A2(2.0) - webhost-redirection

Hello,
We are currently running the version ACE A2(2.0), pretty old one on Cisco ACE Module. We have applied webhost-redirection https://%h%p 302 but it doesn't seem to take effect and always go back to the host header value.
Is it a bug or a missing feature within A2(2.0) build ?
Please assist.
Thanks.

Also is there a way to check in ACE logs as to what are the redirects taking place to identify any issues etc.
Thanks.

ACE WEBHOST-REDIRECT logic

Hi guys.
Recenty I see the following config.
rserver redirect REDIRECT-TO-HTTPS
webhost-redirection https://%h%p 301
inservice
serverfarm redirect REDIRECT-SERVERFARM
rserver REDIRECT-TO-HTTPS
inservice
I suspect this is a generic config to rewrite a redirection sent from rsever to client when it sends a http redirection and the client need to do a https conection.
My question is: this configuration will rewrite all redirect? What happens if the redirect sent from real server need to reach the client as http (not translated)
Thanks in advance.

Hi David,
The above configuration is for ACE to redirect and not "Rserver". So if a user comes on http://xyz.com and you want ACE to redirect it to https"//xyz.com, you use above configuration. Now there will be a class-map condition as well as policy maps and hence ACE will redirect only those requests which will match the condition. Also, redirect and rewrite are two different functions. If you want the ACE to intercept server response and rewrite it, then you should have a look at "URL Rewrite as well as SSL rewrite" features. Again you will have proper configurations place for ACE to decide what to rewrite and what not.
Let me know if you have any questions.

CISCO ACE forward to Sorry page

Hello everyone,
I have a problem with Cisco ACE. I want to view Sorry pages when primary server farm is not available, but this sorry pages should be loaded from other server farm with specific URL.
When my site (https://www.mysite.com) is not available and all my servers in server farm is shutdown clients who visit page should see on main pages (https://www.mysite.com) Sorry Pages, this sorry pages is on other server farm in specific url.
So my question is: How to redirect client to other server farm to specific URL where is static pages for example /folder/maintenance.html?

You cannot add a normal host in a redirect serverfarm:
====not good=====
host1/Admin(config)# rserver BSERVER3
host1/Admin(config-rserver-host)# ip address 192.168.12.6
host1/Admin(config-rserver-host)# inservice
host1/Admin(config-rserver-host)# exit
host1/Admin(config)# serverfarm redirect SFARM2
host1/Admin(config-sfarm-redirect)# rserver BSERVER3
host1/Admin(config-sfarm-redirect-rs)# inservice
host1/Admin(config-sfarm-redirect-rs)# exit
=======
To acheive what you want you will need to create a redirect serverfarm and a backup serverfarm and use layer7 classification. something like this:
dvishwak/Admin(config)# rserver redirect SERVER4
dvishwak/Admin(config-rserver-redir)# webhost-redirection http://%h/folder/maintenance.html 301
dvishwak/Admin(config-rserver-redir)# inservice
dvishwak/Admin(config-rserver-host)# exit
dvishwak/Admin(config)# serverfarm redirect SFARM4
dvishwak/Admin(config-sfarm-redirect)# predictor roundrobin
dvishwak/Admin(config-sfarm-redirect)# rserver SERVER4
dvishwak/Admin(config-sfarm-redirect-rs)# inservice
dvishwak/Admin(config-sfarm-redirect-rs)# exit
dvishwak/Admin(config)# rserver BSERVER3
dvishwak/Admin(config-rserver-host)# ip address 192.168.12.6
dvishwak/Admin(config-rserver-host)# inservice
dvishwak/Admin(config-rserver-host)# exit
dvishwak/Admin(config)# serverfarm host SFARM3
dvishwak/Admin(config-sfarm-redirect)# rserver BSERVER3
dvishwak/Admin(config-sfarm-redirect-rs)# inservice
dvishwak/Admin(config-sfarm-redirect-rs)# exit
dvishwak/Admin(config)# class-map type http loadbalance match-any MATCH-SORRY
dvishwak/Admin(config-cmap-http-lb)# match http url /folder/maintenance.html
dvishwak/Admin(config)# policy-map type loadbalance first-match L7SLBPOLICY
dvishwak/Admin(config-pmap-lb)# class MATCH-SORRY
dvishwak/Admin(config-pmap-lb-c)# serverfarm SFARM3dvishwak/Admin(config-pmap-lb-c)# exit
dvishwak/Admin(config-pmap-lb)# class class-default
dvishwak/Admin(config-pmap-lb-c)# serverfarm SFARM1 backup SFARM4
This way the backup SFARM4 will redirect to your desired page while still keeping the URL what you desire, and when the redirect hits us back on the same VIP we catch in the layer 7 class MATCH-SORRY and send it to your desired server.

QoS Cisco SCE8000, Caching Cisco IronPort WSA, Loadbalancing Cisco ACE solution

Hi all,
Our customer is a mobile operator. They need a integrated solution for caching, QoS and Loadbalancing in a combination. From my understanding of their goals, they need to providing stable and speedy broadband access as well as good user experience by the differentiation service offering. They need to classify IP traffic and prioritize and control of content-based services for a given subscriber while transparently and dynamically redirect and load balance the application level classified of IP traffic to a proxy caching server regardless of protocols such as http, https, ssl, ftp, flv, mms and rstp, sip, p2p....
Attached pls find the RFP and technical specification for Caching and QoS.
I appreciate your expertise to consult me whether I can propose for them the Cisco ACE standalone appliance or ACE engine module for 7600/6500 for loadbalancing, Cisco IronPort WSA for caching and dual Cisco SCE8000 for QoS as an integrated solution. Is this solution feasible/workable and where could I find the same reference or solution design or technical guidance on this?
Thanks a lot and would like to hear from you at the soonest!
Best regards,

Cisco ACE backend communication

We are performing SSL overloading in Cisco ACE 4710..
443 from client to load balancer then 80 on the backend.. which works fine, however when I change the backend to 8080 I get to the initial screen but everything after breaks,..
It seems to be something with 443 as if I configure the front end to talk port 81 and backend 8080 all works, as soon as the front end is changed to 443 I get to the first page then everything after breaks

Hi Networker,
Kindly use the following command:
ssl url rewrite location expression [sslport number1] [clearport number2]
As per in your case:
CLIENT -----> ACE = port 443 = sslport
ACE --------> Server = port 8080=clearport
Suppose you are specifying SSL URL rewrite for the URL www.cisco.com or www.cisco.net using the default SSL port of 443 and a clear port of 8080,
Then enter:
host1/Admin(config-actlist-mod)# ssl url rewrite location www\.cisco\.* sslport 443 clearport 8080
In the above example, the ACE attempts to perform the following tasks:
1. Match all HTTP redirects to http://www.cisco.com:8080 or http://www.cisco.net:8080
2. Rewrite the HTTP redirects as https://www.cisco.com:443 or https://www.cisco.net:443
3. Forward the HTTP redirects to the client
After you enter the ssl url rewrite command, associate the action list with a Layer 3 and Layer 4 policy map.
Check the URL for your reference:

Cisco ace Load balancer not maintaining session persistence

Hi All,
We have observed from the IIS logs on the internal webservers that loadbalancer is not maintaining session persistence for two specific request for the internal servers.
https://123.xyz.com/Webresource.axd
https://123.xyz.com/ScriptResource.axd
Error
Webresource.axd : 500
Scriptresource.axd: 404
Session persistence is maintained for all other requests hitting loadbalancer.
Issue is observerd on hits for these two specified components. WebResource.axd and ScriptResource.axd are Http Handlers used by ASP.NET and Ajax to add client-side scripting to the outgoing web page.
For e.g /WebResource.axd d=t2GXfySdqWmJ-lZSI0KVbw2&t=634868473645172160 is valid for server 1 and return 200 response but the same request is seen on few other servers where the response is 404 even though load balancer cookie is same. This means that if the request for the both the axd contains a valid decrypter and it connects to the right server then the response seen is 200.
The url passed by the user contains d and t parameters when are unique for each user session.
Solution tried:
Accessed website via another VIP without http redirect rule but could not see difference.
Tried to match machine key across all servers : Failed . Could see the ‘d’ value different for each server.
Load balancer VIP :
x.x.x.x
redirect: http > https
SSL Offload : ON
Poool:
WEB1
WEB2
WEB3
WEB4
WEB5
All servers listening on port 80
sticky config:

sticky http-cookie cookie1 vip-farm:1.1.1.1:443
cookie insert browser-expire
replicate sticky
serverfarm farm:1.1.1.1:443
Has anyone else come across similar issue?
Can you plese check if there is any config on cisco ace that will ensure that session persistence is maintained for these 2 requests.
Thank you for all the help.
regards,
Sangram

Hello Sangram,
We would need simultanous packet traces before and after the ACE to get to the root cause of this issue so I would recommend that you open a cisco tac case for more in depth troubleshooing of this issue.

Cisco ACE - Exempt HTTP URL from SSL Offloading

Hi,
I have a cisco ACE module A2 (3.6). I am offloading url www.abc.com on cisco ACE. HTTP redirection to https is working & over https I am able to browse website perfectly. real servers are redirecting some pages over http. Due to page redirection from webserver I have to exempt one URL (http://www.abc.com/modules/docs/abc.aspx) from ssl offloading. It is possible or as a work around i have to rewrite complete url www.abc.com as ssl port.
Your inputs highly appreciated.
Regards,

Hi Masif,
In case you have not gotten assistance with this one, you just need to specify the specific URL and match it on top of the loadbalance policy that is already doing the redirection.
class-map type http loadbalance match-any No-Redirect
2 match http url /docs/abc.aspx
policy-map type loadbalance first-match ABC
class No-Redirect
serverfarm HTTP-Servers
class class-default
serverfarm Redirect
Hope this helps.

Need help to Configure Cisco ACE 4710 Cluster Deployment

Dear Experts,
I'm newbie for Cisco ACE 4710, and still I'm in learning stage. Meanwhile I got chance at my work place to deploy a Cisco ACE 4710 cluster which should load balance the traffic between two Application Servers based on HTTP and HTTPS traffic. So I was looking for good deployment guide in Cisco SBA knowledge base then finall found this guide.
http://www.cisco.com/en/US/docs/solutions/SBA/February2013/Cisco_SBA_DC_AdvancedServer-LoadBalancingDeploymentGuide-Feb2013.pdf
This guide totally fine with my required deployment model. I have same deployment environment as this guide contains with ACE cluster that connects to two Cisco 3750X (Stack) switches. But I have some confusion places in this guide
This guide follow the "One-armed mode" as a deployment method. But when I go through it further I have noticed that they have configured server VLAN as a 10.4.49.0/24 (all servers reside in it) and Client side VIP also in same VLAN which is 10.4.49.100/24 (even NAT pool also).
My confusion is, as I have learned about Cisco ACE 4710 one-armed mode deployment method, it should has two VLAN segments, one for Client side which client request come and hit the VIP and then second one for Server side. which means besically two VLANs. So please be kind enough to go through above document then tell me where is wrong, what shoud I need to do for the best. Please this is an urgent, so need your help quickly.
Thanks....!

Dear Kanwal,
I need quick help for you. Following are the Application LB requirements which I received from my clinet side.
Following detail required for configuring Oracle EBS Apps tier on HA:
LBR IP and Name required to configure EBS APPS Tier (i.e, ap1ebs & ap2ebs nodes)
Suggested IP and Name for LBR:
IP : 172.25.45.x [should be on same 172.25.45 subnet of ap1ebs & ap2ebs nodes]
ebiz.xxxx.lk [on port 80 for http protocol accessibility]
This LBR IP & name must be resolve and respond on DNS network
Server Farm detail for LBR Setup
Following detail will be use for configuring the LBR:
LBR IP and Name :
IP : 172.25.45.x [should be on same 172.25.45 subnet of ap1ebs & ap2ebs nodes]
ebiz.xxxx.lk [on port 80 for http protocol accessibility]
This LBR IP & name must be resolve and respond on DNS network
Server Farm Detail for LBR setup:
Server 1 (EBS App1 Node, ap1ebs):
IP : 172.25.45.19
Server Name: ap1ebs.xxxx.lk [ap1ebs hostname is an example, actual hostname will be use]
Protocol: http
Port: 8000
Server 2 (EBS App2 Node, ap2ebs):
IP : 172.25.45.20
Server Name: ap2ebs.xxxx.lk [ap2ebs hostname is an example, actual hostname will be use]
Protocol: http
Port: 8000
Since my client needs to access URL ebiz.xxxx.lk which should be resolved by IP 172.25.45.21 (virtual IP) via http (80) before they deploy the app on the two servers I just ran web service on both servers (Linux) and was trying to access http://172.25.45.21 it was working fine and gave me index.html page. Now after my client has deployed the application then when he tries to access the page http://172.25.45.21 he cannot see his main login page. But still my testing web servers are there on both servers when I type http://172.25.45.21 it will get index.html page, but not my client web login page. What can I do for this ?

Urgent!!! Cisco ACE and asymetric routing assistance needed

I am wondering if someone can give me pointers on the cisco ACE
and asymetric routes. I've attached the diagram:
-Cisco IOS IP address is 192.168.15.4/24 and 4.1.1.4/24
-Firewall External interface is 192.168.15.1/24,
-Firewall Internal interface is 192.168.192.1/24,
-F5_BigIP External interface is 192.168.192.4/24,
-F5_BigIP Internal interface is 192.168.196.1/24 and 192.168.197.1/24,
-host_y has IP addresses of 192.168.196.10/24 and 192.168.197.10/24,
-Checkpoint has static route for 192.168.196.0/24 and 192.168.197.0/24
pointing to the F5_BigIP,
-host_y is dual-home to both VLAN_A and VLAN_B with the default
gateway on host_y pointing to VLAN_A which is 192.168.196.1,
-host_x CAN ssh/telnet/http/https to both of host_y IP addresses
of 192.168.196.10 and 192.168.197.10.
In other words, from host_x, when I try to connect to host_y
via IP address of 192.168.197.10, the traffics will go through VLAN_B
but the return traffics will go through VLAN_A. Everything
is working perfectly for me so far.
Now customer just replaces the F5_BigIP with Cisco ACE. Now,
I could not get it to work with Asymetric route with Cisco ACE. In
other words, from host_x, I can no longer ssh or telnet to host_y
via IP address of 192.168.197.10.
Anyone knows how to get asymetric route to work on Cisco ACE?
Thanks in advance.

That won't work because ACE uses the vlan id to distinguish between flows.
So when the response comes back on a different vlan, ACE can't find the flow it belongs to and it drops it.
Even if we could force it to accept the packet, ACE would then try to create a new flow for this packet and it will collide with the flow already existing on the frontend.
You would need to force your host to respond on the same vlan the traffic came in.
This could be done with client nat on ACE using different nat pool.
Gilles.

Cisco ACE loadbalancing matching more than one header in L7 class map

Dear All,
This is regarding Cisco ACE loadbalancing matching more than one header in L7 class map. I have a small setup with ACE 30 module in Cisco6500. I have got three webservers. Presently I have following configuration where I am mathing one url header.
class-map type http loadbalance match-all L7_WEB_HEADER_MATCH
description MATCH THE HOST HEADER OF HTTP REQUEST
2 match http header Host header-value ".*abhisar.com*"
So for above configuration, when traffic is coming for abhisar.com, it is working fine.
Now, I have following headers and DNS entry is pointing to same virtual IP for all http url header same as abhisar.com
abhisarindia.com
indiaabhi.com
So new configuration will be
class-map type http loadbalance match-any L7_WEB_HEADER_MATCH
description MATCH THE HOST HEADER OF HTTP REQUEST
2 match http header Host header-value ".*abhisar.com*"
4 match http header Host header-value ".*abhisarindia.com*"
6 match http header Host header-value ".*indiaabhi.com*"
So just want to confirm if this is fine.
Thank You,
Abhisar.

Dear Rajesh,
Thank you for reply. I will let you know once I carry out this activity.
Thank You,
Abhisar.

Slow connection in one server if accessing through Cisco ACE

Hi,
Good day, Can someone help me on my problem? I have 3 servers, server1, server2 and server3.

Hi Earsdale,
All the three servers are using the same configuration, so, I'm afraid it's not possible to give you a simple answer. You will need more troubleshooting.
I would recommend you to start by checking the differences between the servers because one of those differences is certainly causing the failure.
Also, it would be helpful to get traffic captures on the TenGig interface of the ACE to compare the behavior of the connection when going to the different servers, as well as the differences when being load-balanced vs accessing the server directly.
If you need help with this troubleshooting, you can always open a TAC service request

Cisco ACE dynamic rerouting (dc to dc failover)

Good day,
We currtenly have two dc's (site A and site B)
We are using netapps as our SAN and we ar booting our server directly from the SAN
SAN A and SAN B are insync and the network between site A and site B is routed.
The challange:
When a server is failover from site A to B it still has an ip adress that is routed to site A.(due to the SAN boot)
We have a cold - hot design in regards to the servers (so no clustering of ESX)
I have been reading about cisoc ACE and i think that it would solve the challange by dynamily updateing OSPF.
Can any one please confirm that cisco ACE will solve this challlange (whitout the need for any other additional hardware)
Thanks a lot,
Regards,

It's more related to disaster recovery planning than ACE configuration
The cleanest way is to use L2 extension.
Otherwise you can use VMWare SRM to change the ip addresses of your VMs, or run an OSPF process and replicate all the subnets and put it in the "shutdown state" (or announcing it with a very high cost, proximity routing will do the rest - ACE module can do this for the VIPs with OSPF route health injection, ACE4710 doesn't support RHI but on the upstream router you can define an IP SLA probe and perform conditionnal redistribution), or use a dummy VRF with all your subnets and when enabling DRP, perform route leaking... use NAT with DNS-based failover etc...
There is no generic answer to your problem.

How can ftp service on non-standard port be load balanced using Cisco ACE.

How can ftp service on non-standard port be load balanced using Cisco ACE.For example ftp service required on tcp 2000 port

Hi Samarjit,
you can do this by specifying the port number in the class map that you create . Please find the below mentioend config guide where you can specify the tcp/udp port , range or ports or even the wild card to match the port.

Logging user commands in Cisco ACE appliance

Good afternoon gentlemen
I need to configure the same as shown below in Cisco ACE Appliance. The requirement is logging all user access login (whether failed or succeeded) and also logging all commands that users issue.
#IOS commands
no logging console
logging buffered 307200 informational
service timestamps log datetime localtime show-timezone
logging trap debugging
login on-failure log
login on-success log
archive
   log config
      logging enable
      logging size 500
      hidekeys
      notify syslog contenttype plaintext
If you guys have an idea please answear
Regards
Christian

Hello Arun,
we saw before the message you report, it's probably a symptom of:
CSCtx03563
or
CSCue38032
I would suggest opening a TAC case to get this properly investigated.
Kind Regards,
Francesco

Monitoring the Cisco ACE module with SNMP

We use 2 redundant Cisco ACE loadbalancer in our datacenter
The models are ACE20-MOD-K9 with software A2(2.0)
Does anybod know how to monitor the environment (cpu, memory) of such a module with snmp?
We were not able to find an applicable MIB for that module.
The CISCO-PROCESS-MIB.oid (ftp://ftp.cisco.com/pub/mibs/oid/CISCO-PROCESS-MIB.oid) seems not to reflect the correct oid's.
What are the correct oid's for cpu and memory?
Where can I find a detailed documentation for snmp-monitoring the cisco ace module?
thanks

Hi Patrik,
to monitor the ACE I use these two MIB's:
ftp://ftp.cisco.com/pub/mibs/v2/CISCO-SLB-MIB.my
ftp://ftp.cisco.com/pub/mibs/v2/CISCO-ENHANCED-SLB-MIB.my
Example for CPU:
