ACS 4.2"secondary"
Dear all,
I have two servers and ACS 4.2, main one installed on each of them is well configured and all AAA clients authenticated successfully from it, also of database replication works very well between two servers, the question is when the primary one goes down the AAA clients not authenticated that secondary.
Here is the configuration on all devices:
AAA new-model
by default the authentication of connection ! Hi Hassan,. Since you're using the Ganymede group +, no need for the lines below. 5. host 192.168.2.100 GANYMEDE-server timeout key
Another option to make sure that your secondary acs works fine, you can delete the primary acs from your definition of ACS group. HTH Kind regards Chris Tags: Cisco Security Registration of ACS 5.3 secondary Hi I just had to rebuild my system ACS with new hardrives, but I'm unable to register the devices to each, I get a system error. I thought that it could have something to do with the unit refurbished is not joined to the domain, but it has now been joined, but using a different advertising account, but still cannot register at the elementary level. Any help is appreciated? Super-admin GUI are used to record secondary to primary school can check you what are the rights we have for acsadmin. Jatin kone ACS database does not not after having changed the secondary ip of acs. Hello.. Im having 2 ACS 3.1 server. ACS01 (primary) & ACS02 (secondary). We recently moved ACS02 to another site and has changed its ip address. When we of database replication from ACS01, we received the error message saying ACS02 has refused the request of replication. Any idea what can be the problem? Consider these elements when you implement the database replication feature Cisco Secure: (1) ACS supports only supported replication of database to other ACS servers. All ACS servers participating in the Cisco Secure database replication must run the same version and patch to FAC level. (2) the principal server copy compressed and encrypted the database on the secondary server components. This transmission is done via a connection TCP, Port 2000. The TCP session is authenticated and using an encrypted protocol, Cisco-owners. (3) only hosts properly configured, valid ACS can be secondary servers. To add a secondary server, configure it in the AAA servers table in the section of this document Network Configuration. When a server is added to the AAA servers table, the server is displayed for selection as a secondary server in the list of AAA servers as replication partners, on the Cisco Secure database replication page. (4) the principal server must be configured as an AAA server and must have a key. The secondary server must have a primary server configured as an AAA server and its key for the primary server must match the key primary servers. (5) secondary servers replication takes place sequentially in the order listed in the replication list under replication partners, on the Cisco Secure database replication page. (6) the secondary server that receives the replicated components must be configured to accept replication of database from the primary server. To configure a secondary server for database replication, refer to configuring a secondary Cisco Secure ACS Server of this document section. (7) ACS does not support two-way replication of database. The secondary server, which receives the replicated components, check that the primary server is not on its list of replication. If this is not the case, the secondary server accepts replicated components. If so, it rejects the components. (8) to replicate the seller of RADIUS defined by the user and the configurations of the specific attribute (VSA) provider successfully, definitions have to be replicated must be identical on the primary and secondary servers. This includes seller RADIUS slots occupy sellers RADIUS defined by the user. For more information on the sellers of the RADIUS and the VSA attributes defined by the user, see section User-Defined RADIUS vendors and VSA sets the document Cisco Secure ACS database command-line Utility. Unable to save the secondary instance of ACS. Hello I did upgarde IOS on an instance of the ACS and tried to register in the main proceedings. I get an error message 'Could not be saved due to IP address or hostname not valid'. > IOS is the same as in the primary. > DNS is resolve the two instances of ACS IP address. > Tried with the two great account admin (default and created manually) Still I am facing the same issue. Related snap is attached. Can someone help me on this please. I was unable to view the image. Number of certificate to ACS secondary Hello We distributed the deployment model ACS where primary ACS can do the role of configuration and secondary ACS made the oversight role. Our certtificate of root has been exceeded two days back and we have installed this kind of forgot to install on secondary ACS primary GBA. For this reason, our some wirless useers could not connect wireless with authentication with fail messages. So my question is, ACS primary and secondary are accepting the request of AAA and you answer that we use the deployment of didtributted model. Or can share any document from cisco that shows this? The WLC send the primary ACS server authentication and will only use the secondary image if there is no response from the primary. The WLC is not fail the primary unless the secondary does not respond or if you have active relief in which the WLC will check if the primary is in place. Sent by Cisco Support technique iPhone App Cannot replicate from the primary to the secondary servers ACS I have a primary ACS server and secondary and trying to replicate the primary database to the secondary. When I do, the seconary reports 'inbound replication of database of ACS '
Version is 4.1 on Windows Server 2003. What version of acs do you use, and it is in fact the shared secret for the AAA servers and not the shared secret for the encryption of the database. There is a known bug, if you look at the free entry on the two instances of the acs is either one of them shows a loopback address and not the real ip address? If Yes, then you hit the bug I mentioned. The best way to solve it is to access the console as and change the ip address (for example to enable the dhcp pull an ip address and let the services restart). Then go back into the box and assign the static ip address you used. Services once to return to verify that the entered car now has the correct ip address (physical and not looping) and test your replication again. Thank you Tarik Hello I currently have a Cisco ACS 3.3 Server. I want to upgrade the server to the latest version and cluster with one another so that we can have a redundant infrastructure because if one fails it also includes... Can provide you a solution for this? Thank you Hello The latest version is 4.1 ACS. You can upgrade 3.3.3 build 11 directly to 4.1. Then, you can install an another ACS 4.1 on a different machine and replication configuration between these two. In this way, you will need to make changes to only one that ACS and the secondary will be automatically updated. Once these two are defined, you can set both of these servers as a server Radius/Ganymede on devices and there will be a redundancy. Kind regards Vivek I have following querry in refrence to the ACS configuration 1 - the advantages or disadvantages of ACS - 5.4 VM vs use 2. can we have instance ACS - 5.4 VM configured as main and ACS unit as secondary Hey,. 1 - a virtual machine performance is slower than on a real device from 1120 because of the overload of the virtual machine. A virtual machine performance increases when you increase the CPU resources. http://www.Cisco.com/c/en/us/TD/docs/net_mgmt/cisco_secure_access_contro... VM are built into your existing infrastructure of the vm. No additional hardware. Revival of the virtual machine is easy. 2 - Yes Rate if useful :) Knowledge sharing makes you immortal. Kind regards Ed How do Active/Backup (replication config) ACS 4.1 Hello I tried to find a way by which I can do on my ACS active & the other as secondary IE how I can reproduce the config made on an asset to the backup of the acs. I m using ACS SE 4.1 Thanks in advance for your suggestions. -Piyush Hello You can use the box RDBMS synchronization to synchronize the 2 boxes of ACS, but I don't think that there is a way to make an active and the other secondary on the ACS itself. If you are authenticating users of your switches wireless etc... You can do first appears in ACS 'active' and 'secondary' GBA listed second. This secondary GBA would only used it actively it was not available. HTH Craig Devices configured for authentication under ACS Hi friends, Would like to know how many devices can be configured for authentication under ACS version 5.6.0.22 (Cisco Secure Network Server 3415). I'm not able to find the same everywhere. Concerning JN Hello It depends on the license that you install on the ACS 5.6. All deployments of 5.6 ACS supports customers AAA 100 000, 10,000 network, 300,000 users and 150 000 host device groups. 5.6 ACS collector server log can handle 2 million records per day and 750 messages per second for stress sent by the various nodes of ACS in the deployment on the server of log collector. Please visit this link: http://www.Cisco.com/c/en/us/TD/docs/net_mgmt/cisco_secure_access_contro... With the Base license, a Cisco Secure ACS 5.6 appliance or virtual machine software can support the deployment of up to 500 devices of access network (DNA) such as routers and switches. These are not authentication, authorization and accounting clients (AAA). The number of network devices is based on the number of unique IP addresses that are configured. The limit of 500-device is not a limit for each individual device or the instance, but a limit of scale that applies to a set of instances of Cisco Secure ACS (primary and secondary instances) that are configured for replication. The optional add-on of large deployment license allows deployment to support over 500 network devices. Only one major deployment license is required by the deployment because it is shared by all instances.

[Cisco ACS] 11036 the RADIUS Message Authenticator attribute is invalid Hello I had a lot of Cisco AP related to Cisco WLC 2. On each WLC, I configured a primary and a secondary RADIUS server. RADIUS servers are Cisco ACS 5.2.0.26 (patch 10) ACS primary and secondary configurations are synchronized. There is no problem between primary rules WLC and Cisco ACS (primary and secondary). When secondary WLC asks primary Cisco ACS, I get this error "11036 the RADIUS Message Authenticator attribute is not valid. WLC secondary contacts automatically secondary Cisco ACS and it works fine. Cisco ACS description for this error: "this can be reason of mismatched shared Secrets." The two Cisco ACS are synchronized, so I should have the same error on them... Why primary ACS generates this error? Thanks for your help, Patrick Patrick: The shared secret mismatch could be on the side WLC, not on the side of the ACS. Make sure that the shared secret of the radius primary server is configured correctly on the secondary WLC. HTH Amjad Rating of useful answers is more useful to say "thank you". Hi all I know that GBA replicates the entire base of primary secondary and not vice versa... My scenario is: ACS main breaks down, and the secondary takes over... now, all adding user etc, is done on the ACS secondary... now, when the primary comes back once again, will it overwrite the secondary database and should we recreate the configs? or what secondary GBA replicates its data to the primary? its a little confusing! I have I'll do the ACS replication in a few days and wanted to be really sure of that. REDA Hello If you configure a redundant ACS server as secondary. All the primary databases will be replicated to secondary education. As you said what if secondary caught takes over and Setup takes place on the secondary. He will be on the primary. depends on how you configure. check that there is the possibility to send and receive. This link will be helpful for you. http://www.Cisco.com/en/us/products/sw/secursw/ps2086/prod_configuration_examples_list.html Presentation of the GANYMEDE solution Hi guys,. We need a centralized solution for authentication of devices (routers & switches) and we opt to use GANYMEDE. Except ACS 5.x is there any other tool that you can recommend this requirement? Second: equipment spread on both the EU, North America and Asia. How can I combat this? Install two instances in the EU and that of NA? Thank you very much Florin. Cisco ACS is a solution proven to a centralized authentication, router and switch. I install a RADIUS server as your primary and replicate in the secondary. I would do this with virtual machines for ease of maintenance and support. As to whether you are installing a GANYMEDE solution on every continent that you support, you could justify this function of how many devices is in every part of the world.

RADIUS authentication fails for one of our network device 5.1 of the ACS is default for authentication authentication Ganymede to the ASA firewall, becomes That's what I suspected. You will have to write off the primary secondary ACS. Configure the appropriate ACS secondary clock and time zone to match both domain controllers. Both the change in the clock and time zone change will restart the ACS secondary services for the changes to take effect. After you have configured the time comes, we should "Test connection" against AD from the ACS on the secondary interface. As soon as he gets that we can go ahead and save changes and also register for the secondary back to the primary. This should solve the problem. Kind regards.
