ACE - Class-maps

I want to load balance traffic to a VIP based on client source address. Here is what I had in mind:
access-list special-25 extended permit tcp host 10.20.138.18 host 10.20.96.19 eq 25
access-list special-25 extended permit tcp host 10.20.138.30 host 10.20.96.19 eq 25
access-list special-25 extended permit tcp host 10.20.138.40 host 10.20.96.19 eq 25
access-list special-25 extended permit tcp host 10.20.254.88 host 10.20.96.19 eq 25
access-list internal-25 extended permit tcp 10.20.0.0 0.0.255.255 host 10.20.96.19 eq 25
access-list internet-25 extended permit tcp any host 10.20.96.19 eq 25
class-map match-any INTERNET-MAIL

policy-map multi-match CLIENT-VIPS
class VIP-MAILGATE-25
loadbalance vip inservice
loadbalance policy MAILGATE-POLICY

The problem with this design is the policy-map MAILGATE-POLICY won't accept anything but the "class-default".
Any ideas how can I make this work?
Thanks,
Milo

Gilles,
You're right, it does sound weird. However, it appears to work (the commands weren't rejected anyway). Now as soon as I get time on the real servers I test it out. Here's my modified config with your suggestion:
class-map type http loadbalance match-all INTERNAL-MAIL-TEST
10 match source-address 10.20.0.0 0.0.255.255
class-map type http loadbalance match-any SPECIAL-MAIL-TEST

15 match source-address 10.20.138.30 255.255.255.255
20 match source-address 10.20.138.40 255.255.255.255
25 match source-address 10.20.254.88 255.255.255.255

Thank you!

ACE class-map match url syntax

Can someone help me with the string that would match a url with no path specified? For instance; user types "https://outlook.domain.net" into their browser and I want the ACE to redirect that request to https://outlook.domain.net/owa".
2 match http url oulook\.domain\.net\

Adam and Shday,
I'll give you a hand on this =)
Adam we can solve your problem only if you're doing SSL offloading on the ACE as the layer 5 information that needs to be checked is being sent encrypted.
In case SSL termination is configured then the configuration would be like this:
rserver redirect OWA
webhost-redirection https://%h/owa 301
inservice
serverfarm redirect OWA
rserver OWA
    inservice
class-map type http loadbalance match-any OWA
2 match http header Host header-value "outlook.domain.net"
policy-map type loadbalance first-match OWA
class OWA
serverfarm OWA
class class-default
serverfarm Backend
Shday yours is pretty much the same but you need to decide if class-default needs
to be in place:
rserver redirect Domain
webhost-redirection http://%h/any_path 301
inservice
serverfarm redirect Domain
   rserver Domain
     inservice
class-map type http loadbalance match-any Any
2 match http url /.*
class-map type http loadbalance match-any Domain
2 match http header Host header-value "domain.com"
policy-map type loadbalance first-match Domain

A problem with ACL in the class-map on the ACE module

Hi all,
I configured the following on the ACE module:
object-group network test
host 192.168.1.21
host 192.168.1.22
host 192.168.1.23
object-group service port
tcp eq www
tcp eq 8080
access-list T line 8 extended permit object-group port object-group test any
I tried to configure a class-map for matching this ACL:
ACE-4710-2/Lab-OPT-11(config)# class-map match-any TEST_C
ACE-4710-2/Lab-OPT-11(config-cmap)# match access-list T
Error: Cannot associate acl having object-group ACEs in class-map.
So couldn't I configure the class-map by using ACL with object-groups involved? Is it the bug or the normal behaviour? Because the customer uses object-groups in ACLs and he has to configure ACL without object-groups for the traffic classification. It is horrible.
Thank you
Roman

Hi Roman,
I'm afraid it's the expected behavior. You cannot use an ACL with object-groups inside a class-map.

ACE SSL Sticky class-map generic vs class default differences.

There was a thread recently titled "ACE 3.0(0) SW / LB with SSL Session-ID" where Giles Dufour outlined a configuration for an ACE performing sticky based on SSL Session ID.
Can anyone explain the benefits and differences of using a specific class-map generic such as this:
class-map type generic match-any SSL-v3-32
2 match layer4-payload regex "\x16\x03\x00..\x01.*"
3 match layer4-payload regex "\x16\x03\x01..\x01.*"
Versus just matching class default?
So if I have a configuration such as this:
policy-map type loadbalance generic first-match SSL-v3-Sticky
class SSL-v3-32
sticky-serverfarm ssl-v3
vs
policy-map type loadbalance generic first-match SSL-v3-Sticky
class class-default
sticky-serverfarm ssl-v3
What's the benefit or drawback?

The SSL session id is only available in version 3.0.1 and 3.1.1
So you can match this particular version and then attempt to do stickyness.
You are guaranteed to find what you're looking for.
If you match a class-default it means you apply stickyness to any version of ssl packet.
So there is a risk to misinterpret the content of the packet and stick on something else than the session id.

ACE ignoring class map depending on source???

I have a problem with a the load balancing "not working" properly depending on the source.
The load balancing decision is done with a secondary cookie (?ld=fe1 or ?ld=fe2). If it appears and the value is fe1 the request should go to serverfarm FE1-app. If the value is fe2 then serverfarm FE2-app should be choosen. If it is not present in the http request then serverfarm FE-app in the class-default is taking over.
This approach works if "surfing" to the VIP from a certain part of the internal network. It does not work from another part of the network. It seems that cookie is ignored and only the class default triggers.
The strange thing is that the same approach works for another setup that looks identical (with different rservers and different VIP of course). There the class map for the cookie triggers always.
My question is now: Why does the ACE seem to ignore the class map for the cookie when coming from a certain part of the network? How can I debug/follow a certain connection or load balancing decision?
Here is the config:
rserver host FE1-app

Hi Federico,
The source of the request has no relation with the way ACE handles the connections, so, there are probably other differences in the traffic.
The best way to troubleshoot these kind of connections is taking a traffic capture on the TenGigabit interface connecting the ACE with the switch backplane. Once you have it, you can try to look for differences between the working and failing connections.
From what you describe, I wouldn't be surprised if the issue comes from the fact that there are several HTTP requests inside the same TCP flow (in which case, by default, the ACE will look only at the first one), so I would suggest you to enable "persistence rebalance" for this VIP. For more details, check the link below:

ACE - HTTPS CLASS MAP CONFIGURATION

Hi,
We have a secured web site (HTTPS) currently fronted by Cisco ACE 4170, running version A5(1.2). We are trying to use the http class map to manipulate the traffic flow in the following manner:
https://abc.com/ABC/* -> serverfarm#1
https://abc.com/* -> serverfarm#2           (Default)
Tecnically this should not be difficult and below is a sample of our configuration. We have similar configuration working on our non-secured web site (HTTP) However for the secure web site, the https request https://abc.com/ABC/xxx is continued being routed to serverfarm#2 instead of serverfarm#1 which is very frustrating.
We can easily get this working on my F5 LTM within 5 minutes but this Cisco ACE continue to frustrate me...Appreciate if any expert on Cisco ACE can help to advise on our configuration.. Thanks.

Kanwaljeet,
Yes, we are using ACE for SSL termination i.e. front end is https and back-end is also https.
We are doing end-to-end encryption as our IT security and audit wanted end-to-end encryption between the client and servers. ACE should be able to look at the HTTP header at the front end since the client SSL session is terminate on the ACE.
Below is an extract of the configuration, I've leave out the remaining configuration which is not required.

ACE: a class-map with multiple ports... what about the probe/serverfarm?

Hello Gilles,
One question about something I was not able to find in the documentation.
Lets say I have one class-map which includes 2 ports (in this case https and 5061).
Can I associate this class-map to just 1 generic serverfarm and probe for both ports or I have to specify 2 serverfarms/rservers/probes?
So, by not specifying the ports on the rserver, if a request is received on port 443 (or 5061), it is sent to the same respective port on the rserver?
The same way is valid for the generic probe. ACE module is able to probe both ports based on the class-map?
Thanks and have a great day!!
Giulio.

Even if you use the 4710 appliance or expect the inheritance in the module software, it's worth considering if this is really what you want. If you keep multiple ports in the L3/L4 class-map you can't handle the services independently. You will have a common serverfarm for both https and 5061. If https service stops on one rserver, the ACE will place that rserver (and not that service) in out-of-operation state and it won't receive any 5061 traffic either. (You have the fail-on-all probe option but I wouldn't say it's a better choice. In that case, https traffic would be sent to the rserver even if https port is closed as long as there is at least one working service on it.) That's why I prefer a separate class-map and separate serverfarm for each service. (They can contain the same rservers, no need to duplicate.) BUT if the software supports probe port inheritance, you can benefit from it even in this scenario: serverfarm-443 and serverfarm-5061 can both use your PROBE_GENERIC_TCP.

Issue with ACE HTTP class map

This is what I want to achieve USING the ACE as a reverse proxy.
User uses the url https://abc/password - gets to the destination server & the web page
If user tries to use any thing additional then the connection is dropped at the ACE such as
https://abc/password/test or any such variation.
Following is the config I have to achieve this
class-map type http loadbalance match-any L7-CLASS-TEST
match http url /password
match http url /password/
class-map type http loadbalance match-any L7-CLASS-TEST-deny
2 match http url .*.*
policy-map type loadbalance first-match LBP-TEST
class L7-CLASS-TEST
    serverfarm FARM-TEST
    ssl-proxy client TEST
class L7-CLASS-TEST-deny
    drop
class class-default
    serverfarm FARM-TEST
    ssl-proxy client TEST
The problem with this is when the page opens I get broken links on all the images. If I use the following line
match http url /password.*
I get the images to work but the user can use the https://abc/password/test which is not what I want.
Has any one faced this issue ?
Any help will be appreciated.
Thanks in advance
Prasanna

Prasanna,
What about if you try it in HTTP and apply the following change?
class-map type http loadbalance match-any L7-CLASS-TEST-deny
2 match http url /.*
This should work in HTTP but not with HTTPS
Anyway, it should not work since everything seems to be encrypted, you may require either SSL-termination or END-TO-END SSL for this then the ACE can decrypt the request see what it needs to do and take the load balance decision.

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.

ACE - FQDN in a class map or other suggestions

It appears it is only possible to use an IP address when creating match conditions in a class map which makes sense.
We are using this basically as a NAT.
ie, server sends an HTTP message to the ACE containing XML
ACE then encrypts with an SSL cert and substitutes a public IP address and sends the XML out to a customer IP on the public internet
Problem is when customer changes the IP address, we need to change the configuration on the ACE. Ideally if I could use a DNS name, then the customer can manage any changes via DNS and not involve us.
Disclaimer: I'm a complete novice to the ACE
Any ideas appreciated!

Hi Rob,
Can you share the current configuration and also the traffic flow here.

Class-maps used for load balancing on ACE

I am from CCS background and am trying to understand how the VIPs could be configured on an ACE module (using class maps).
I am looking for specific information for the following :
1. Will each VIP have a corresponding Service-policy on the VLAN Interface or can we club many VIPs (through policy-maps) onto a single service-policy entry on teh interface?
2. I could not find any cisco doco with the configuration examples for more than one VIP address and would please like to know some examples, if possible or could some one direct me to a doco with many VIP entries ?
- Should each VIP have a seperate class-map or can list them together?

You will have to configure L3/L4 class-maps for corresponding VIPs. You just need a single policy with n class-maps for n VIPS.
I am writing a sample that will hopefully help you on this
class-map match-all app1-vip
match virtual-address 10.1.1.1 tcp eq 80
class-map match-any app2-vip
match virtual-address 10.1.1.2 tcp eq 443
policy-map type loadbalance first-match L7app1
class class-default
server-farm App1-farm
policy-map type loadbalance first-match L7app2

Cyrillic characters in Layer-7 Class Maps statements ?

Hi,
For a specific implementation, I need the ACE to parse URIs with cyrillic characters in a Layer-7 class-map. Does the ACE-4710 support it ?
If yes, how to enter them in a L7 class-map statement like : match http url /Искусство.*
Thank you for any hints
Yves

Hi Yves,
I cannot find anything regarding this and i don't see a way to put that in there. I tried pasting it in my ACE and it didn't take it. I would suggest to open a TAC case for official confirmation.

Layer 7 class-map with different match types

Hello,
I am fighting with a problem on an ACE-4710 version A3(2.4) configuation. I just want to configure a layer 7 class-map that matches if one of two conditions is true. The problem is that these conditions are not from the same type and the ACE refuses the second match statement. However, in the configuration guide, it is clearly defined that it should be possible :
Here is what the configuration guides says :
host1/Admin(config)# class-map type http loadbalance match-any CLASS3
host1/Admin(config-cmap-http-lb)# 100 match http url .*.gif
host1/Admin(config-cmap-http-lb)# 200 match http header Host header-value XYZ
host1/Admin(config-cmap-http-lb)# exit
If I test exactly the same configuration in a context of my ACE, I receive an error message :
CH01AC03/P-104-A(config)# class-map type http loadbalance match-any CLASS3
CH01AC03/P-104-A(config-cmap-http-lb)# 100 match http url .*.gif
CH01AC03/P-104-A(config-cmap-http-lb)# 200 match http header Host header-value XYZ
Error: Match-any classmap can not have different type of match
If I use nested class-maps, I receive the same error message !
Is it a known problem or is it a solution for it ?
Thank you for any help
Yves

Hello Yves,
The command error is correct. I'll take a look at the docs and see about getting them corrected, if necessary.
Basically, for a match-all, you would have to use different types. For example, there will only be one Host header, so you would only specify it once using regex or a fixed string. As you found out, the match-any requires that they all be of the same type. See my example below:
class-map type http loadbalance match-all HEADER-AND-URL
100 match http url /login.*
200 match http header Host header-value "XYZ"
class-map type http loadbalance match-any URLS
100 match http url .*\.gif
200 match http url .*\.jpg
class-map type http loadbalance match-any HEADER
200 match http header Host header-value "CISCO"
policy-map type loadbalance first-match SLB_LOGIC
class HEADER-AND-URL
    serverfarm LOGIN-FARM
class URLS
    serverfarm IMAGES-FARM
class HEADER
    serverfarm CISCO-FARM
class class-default
    serverfarm WWW-FARM
So let's say you want to match requests for URLs ending in .jpg or for requests with Host header XYZ, and if it matches either one, then send to the same serverfarm.
class-map type http loadbalance match-any URL-JPG
2 match http url .*\.jpg
class-map type http loadbalance match-any HOST-XYZ
2 match http header Host header-value "XYZ"
policy-map type loadbalance first-match SLB_LOGIC
class URL-JPG
    serverfarm SERVER-FARM
class HOST-XYZ
    serverfarm SERVER-FARM
If you wanted to send these requests to the farm only if they matched BOTH matches, then you could do it as follows:
class-map type http loadbalance match-all HEADER-AND-URL
   100 match http url /login.*
   200 match http header Host header-value "XYZ"
policy-map type loadbalance first-match SLB_LOGIC
   class HEADER-AND-URL
     serverfarm LOGIN-FARM
Hope this helps,
Sean

Layer-7 Class-maps: 'not' match-any

Hallo All,
I'm wondering if the following logic is possible on the ACEs.
First Match is:
class-map type http loadbalance match-any CM7-MatchSrcIP
   10 match source-address 192.168.0.0 255.255.0.0
   20 match source-address 172.16.0.0 255.255.0.0
class-map type http loadbalance match-any CM7-URLs
   10 match http url /testing.*
class-map type http loadbalance match-all CM7-WWW
   10 match class-map CM7-MatchSrcIP
   20 match class-map CM7-URLs
If the above URL and IP sources are matched, I want to send to a specific SF. (easy enough)
If the URL matches /testing.* but source IP address doesn't match of any of the above subnets, I want to redirect to a 'restricted' page. (ummm)
If the URL is something else (e.g. /temporary.*) with any IP source address, I want it to be load-balanced by a different SF (say like in a class-default)
Thx in adv
David

Hi David,
Sure you can try this on the ACE, you already created most of the configuration so now just need to apply the maps under the first-match policy.
According to your description this is how this policy should look like:
policy-map type loadbalance first-match SLB_LOGIC
class CM7-WWW
    serverfarm Testing
class CM7-URLs
    serverfarm Restricted
class class-default
    serverfarm Any
- ACE checks for testing plus IP address matching.
- If user belongs to any other subnet then SF restricted is used.
- If none of the above statements is matched then defaul class map and SF is used.

Using Wildcards in HOST Class-Map

I want to use a wild card to match a HOST in a class-map. I want to match multiple hosts for the same site:
? Support.Cisco.com
? Employee.Cisco.com
? Helpdesk.Cisco.com
I want to match this with *.Cisco. Will this work?

You are right, my mistake
