Cisco Application :: 4710 ACE Source-address Matching In Nested Class-maps Not Working
Sep 6, 2012
Im having a (from google-fu) seemingly unique issue with load balancing. So for background, I am running the ACE 4710 device in "on a stick" mode, so I am using NAT and all that good stuff. I am also utilizing class maps and host header matching so I can save on IP space. [code]
Basically, as soon as I add that ACL_CLASS_beta.mainsite.com class map, all I get back from the ACE is RST packets and it comes back with an L7 LB Policy Miss.
It SEEMS like it should work, but it doesnt seem to like matching on those source addresses at all.
I'm currently looking at doing some re-design work for a platform we manage on the ACE.I want to be able to run a single VIP and only do a sticky session based around specific URL's not all. I've got the following configuration to apply a sticky session to a URL. [code]Notice, under the Policy-map type loadbalance http first-match WEB-POLICY-L7 i have two class statements, one that matches the URL L7 policy and applies a sticky farm and the second class falls into the default.Am i right in saying with this configuration, any http traffic hitting the VIP 192.168.1.1 that does NOT match /urltobedefined.co.uk/test sticky sessions are NOT applied. But traffic hitting 192.168.1.1 that does match /urltobedefined.co.uk/test will apply the sticky policy?
I have a requirement to provide stats on a per-department, per-destination basis between sites. If I take Voice as an example I have 5 child classes referring to the 5 departments each matching EF and a particular access-list that matches the department's subnet. I tie these 5 child classes into a parent Voice class-map.
Now when I issue a "show policy-map interface" command I see stats for the parent class-map only whereas I would expect to see a breakdown for each of the child classes which is what is required.
I've configured the ACE4710 to bring the logging to a syslog server! Here's the configuration
[...] logging enable logging fastpath
I saw to log with connection on the syslog server but It would be interesting to know the "source ip address" and my question is : It may be possible to configure for the logging a kind of "transparent pass through"?
I'm trying wrap my head around bandwidth guarantee for nested maps. I tried adding a new class to two of my policy-maps today, and got this error: 3945E-1(config-pmap-c)#bandwidth 3000 Insufficient bandwidth 3000 kbps for the bandwidth guarantee
I'm not sure how it knows that with the nested maps and how it's computed. I have a 100mb WAN connectin going to 19 branches. I have a class-map that identifies traffic to the individual branch and within that class, a policy-map is applied to prioritize voice over video etc.
Here's the QoS setup:
class-map Branch1-Policy match access-group branch-1-acl * *
I was adding the Video-Conf class to both Traffic-6calls and Traffic-10calls when I got the above error. How would that percentage be calculated? I know by default i can only reserve up to 75% of interface bandwidth. The platform is 3945E running 15.1(3)
I have a Cisco ACE with a server farm "intranet" with real servers rsrv1 and rsrv2 (round robin) and i have two sites A (IP Address A) and B (IP Address B) in the WAN. I want to that Site A conect to ACE 4710 via VIP, but this connection will be to srv1 and Site B conect to ACE 4710 via VIP, but this connection will be to srv2.
I hav ACE 4710, I am trying to configure a policy in which when specific Client tries to access the specific Destination. ACE should not send the traffic to load balancing. It should directly send to the next Hop.
I configred the below but didnt able to achieve my object.
access-list source_IP line 8 extended permit ip host 192.168.146.123 host 198.xx.xx.2 class-map match-all CM_BYPASS_SOURCE 2 match access-list source_IP
policy-map type loadbalance http first-match PM_L7_BYPASS_SOURCE class class-default forward
But I am not able to reach to destination. MY source traffic is still diverting to the Load balancing server. I dont want it to redirect to LB server
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 a requirement to bypass some specific traffic (with particular source to specific internet destination) in ACE 4710.
All the webtraffic (http and https) is configured to loadbalance to my proxies , i need to configure some specific traffic with source and destiantion to internet to byepass from this loadbalancing and directly got to outside interface .
I got myself lately Cisco SR520 router with some basic firewall functions built in. This is going to be used for my home broadband, so no need to be really super secure, as it would be for some business. I managed to configure it, however there are few things on the firewall side, which I don't understand.
This router had some default configuration in it's flash, when I bought it. There are class maps.... how it works or how to add/edit rules. Also, do I need to use class maps, or can they be replaced by ACL's to certain extend? How to add/edit class maps rules to allow certain port (eg. 3333). Pease see below part of the default config:
class-map type inspect match-any SDM-Voice-permit match protocol sip class-map type inspect match-any sdm-cls-icmp-access match protocol icmp match protocol tcp [Code]...
I'm trying to configure a zone-based firewall on an SR520 and am confused about the 'not' criterion. The 'zone-design-guide' says (my stress): Class- maps define the traffic that the firewall selects for policy application. Layer 4 class-maps sort the traffic based on these criteria listed here. These criteria are specified using the match.where my intention is to let only LAN hosts with IPs in the range 192.168.1.1 to 192.168.1.7 out through the firewall. There may be an easier way of doing this which I'd be pleased to hear about. But, even if there is, I'd also be interested to know what I'm doing wrong in the above.
I have a problem with an ACE 4710 regarding to the ping of especially one VIP address.
At the Box I setup 10 Servcies, all with different VIP addresses, also the IP is not used duplicate somewhere in the network.
in the class defined under Policy-Map Multi-Match I setup identical to the others loadbalance vip icmp-replay active, the VIP is usable by the defined service http, the serverfarm is up and running all ok so far but this VIP does not respond to ping even the correct arp resolution was done.
I started also a capture locally on the ACE and see the ICMP - Echo coming in, but the box sends no echo-reply back.
In the access-lists Management and so on I allowed icmp and also on all interfaces the icmp guard is disabled...
I configured cisco ace 4710 with ssl-proxy and it is not working,url..When i put https://10.1.41.20 the output is: "There is a problem with this website's security certificate", so i click in "Continue to this website (not recommended)" and the ace dont balance the output show error "Internet Explorer cannot display the webpage". [code]
I have ACE 4710 in context mode. I am doing internet browsing (Port 80) redirection to two proxy servers (Transparent Proxy) as well as I am using this ACE box for multiple other servers load balancing.
I have multiple policies applied on my LAN interface (VLAN 300) where all the users and servers are connected.
Now I am facing problem with one application (PLATTS) which is oil company related application. This application is working fine while directly connected with Internet (extrenal internet connection) or by giving explicit proxy in the user browser.
But In transparent proxy This application is not working and my company policy only allow the transparent proxy not explicit proxy.
Now if on my interface vlan 300 i will remove the service-policy input PM_MAIN_BCPROXY my application will start working but i cant redirect the port 80 traffic to my proxy servers which is also my requirement.
I have recently configured a pair of ACE 4710 appliances in a FT group. The ACE's are deployed in one-arm mode, using Source NAT, with all routing to and from being done by a pair of PIX firewalls.
My configuration does not include the use of an "alias" IP address on the data VLAN interface within each of my contexts.
My understanding is that the "alias" IP address is similar to a HSRP address and if the ACE is deployed in Routed mode the default gateway for the servers can be configured with the "alias" address so as this is always available even if a fail over occurs.
if this is a correct interpretation and of use of the "alias" IP address and if so whether it is required when using a one-arm mode topology?
I have a requirement to load balance OWA 2010 inbound connectivity to 2 CAS servers using a ACE 4710 with sticky sessions enabled.
The CAS servers are currently responding on 80 or 443 at this moment in time. Eventually I want to off load the SSL to the ACE 4710, its currently running on the CAS servers. I need to enable sticky sessions to keep the session to the same CAS server for each internet based connection. I also have a proxy enabled for inbound connectivity so I cannot use source IP.
Here is my configuration but it doesn’t seem to be working, i am currently testing with port 80 connections not SSL.
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 not sure if my terminology is correct when using hairpinning but i was wondering if there is any special config needed when you try to access a content rule VIP from a server that's configured as a member of a source group on the same CSS?
So say i have a content rule with a VIP 184.108.40.206 and i also have two servers 192.168.1.1 and 192.168.1.2 that are part of a source group with VIP of 220.127.116.11. My problem at the moment is if from the servers 192.168.1.x i try to ping the other VIP 18.104.22.168 that's configured on the same CSS then it doesn't work and ping fails. The same happens with HTTP traffic to the 22.214.171.124 VIP.
I would have thought that the NAT of the source group would happen before the routing so the 192.168.1.x IP's would be natted to 126.96.36.199 and then passed over for routing where the CSS would see that the VIP 188.8.131.52 is local and it would send it on it's way.
I thought it might be ACL related but i increased the verbosity of acl logging and couldn't see anything in the logs.The source group works fine on it's own and from the CSS itself i can ping the 184.108.40.206 VIP fine. It just seems that from the source group members i can't ping the VIP.
ACE A2(3.4). Is it possible to set a rate-limit connections per sec from any source IP. For example, if a client is trying to GET a web page 10 time per sec I will send a reset or drop that connection.
i don't know why cu need this feature, he want stickiness based on source ip and source port. Does CSS 11500 support stickiness based on source IP and source port?or is there any other method to support stickness based on source ip and sourceport?
I was trying to set a DHCP pool with 127.16.0.0/16 with RV220W, however, RV220W UI can't save it. It displays "IP Address Range -"Step to reproduce: (it is 100% reproducible)
1. login into RV220W admin web
2. Create a VLAN, id 201
3. Go to "Multiple VLAN subnets", select the VLAN, click edit
4. Enter following info: IP Address: 172.16.0.1 Subnet Mask: 255.255.0.0 DHCP Mode: DHCP Server Domain Name: Cisco Starting IP Address: 172.16.2.100 Ending IP Address: 172.16.10.254 Primary DNS Server: 172.16.0.1 Leave rest of settings with default value. DNS proxy is enabled
5. Press Save button. The UI shows text "IP Address Range -".
Expected result: RV220W shall save the setting and make use of 172.16.0.0 subnet in IP pool. By the way, the error message "IP Address Range -" seems incompleteI tried same setting on netgear FVS318N (very similar settings to RV220W), it accepts 172.16.0.0/16 as DHCP IP pool and works.RV220W has great feature set meets my needs. Its UI is slow and sometime dashboard freezes, which I can live with comparing to features. But DHCP server IP pool can't be class B is huge limitation to me.
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.
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
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
