AAA/Identity/Nac :: Turn Cisco 877 Router Into RADIUS Server?
Apr 22, 2011
I was just wondering if it was possible to turn a cisco 887 Router into a RADIUS Server. What i wanted to do was setup my wireless AP to authenticate using RADIUS, but didn't want to setup another server for the purpose.
getting a Cisco WLC to work with MS NPS server? We've done it before albeit with differnt code versions.
I have a Cisco 5508 WLC running 7.0.116.0 code hosting a WLAN configured for WPA2 with 802.1x for authentication. I have two Windows NPS servers configured as the RADIUS servers for EAP-TLS authentication. Via debug info on the WLC I can see the 802.1x handshake take place with the wireless client and the WLC as well as a successful transmission of an Authentication Packet from the WLC to one of the RADIUS servers. However on the WLC I see repeated RADIUS server x.x.x.x:1812 deactivated in global list and on the NPS server I'm seeing event log errors indicating "The Network Policy Server discarded the request for a user" along with the pertinent auth request info that I would expect the NPS server to receive from the WLC. Based on the WLC debug info I'm never actually getting to the EAP-TLS certificate authentication part. It seems the NPS servers don't like the format of the initial RADIUS authentication request coming from the WLC and so don't respond whcih in turn casues to WLC to switch to the other NPS server which produces the same issue.
Is there any way to set up our ISE to provide Radius instead of acting as Radius Proxy? In our Company we use ACS 4.2 to provide AAA via Tacacs+ and this works proper with all our Cisco-Switches. Now we are testing the ISE 1.1.1 as NAC-Solution.
I know how to set up the ISE as 'Radius Proxy', configuring the Sequences and Policies, but till now we are using only Tacacs+ for AAA. The current version of ISE does not support Tacacs+ and I don't want to set up a Radius-enviroment in ACS if not necessary. Somewhere ( I think the specs) I read, the ISE is a merge of ACS and NAC. So in my Opinion there should be a way to provide AAA via Radius on the ISE without ACS and without 'Radius Proxy'.
Wondering if it's possible to send a VSA from my radius server to my ASA-5505 that will instruct the ASA to use one of several split tunnel lists I have created, based on the user name supplied in the Radius request.For example, I can send a VSA of "ip:inacl#1=permit ..." and the ASA will dynamically create an access-list for that user.Is there a similar VSA for split tunnel?
I'm trying to configure ACS 5.4 as radius server for network access (PPP connections).In monitoring and reports the users have green color , but the clients cannot send data. Auth method is CHAP/MD5.
I can authenticate between our MDS 9216i switch and RSA radius server but my role does not come across. The logged in user is a network-operator not admin. In the AV Pair i have defined shell:role*network-admin but it doesnt seem to come across
I have a couple of ACS 5.2 configured as active and backup and I am doing dot 1x authentication using these servers . I have configured the switch with the bellow configuration.
I tried to authenticate and authorized Nokia/checkpoint Nortel/AD3 and Nortel 5510 platform using an 4.1 for windows ACS. the ACCESS-REQUEST is well processed bi the radius server wich send ACCESS-ACCEPT to the AAA Client (ie NORTEL or NOKIA), but i'have got privilege access denied on the Client side. RADIUS IETF Dictionnary is used for every device. all others Cisco Devices authenticate and are well authorized.
We have several ASA 5510 firewalls which are being used as VPN gateways.RSA SecurID is the authentication mechanism using native SDI connectivity. No ACS server is being used.Is it possible to assign user Group and other attributes (such as ACL), using the SecurID RADIUS server? I know this is what the Cisco ACS is for, but is it possible using the RSA RADIUS server itself?
I am configuring TACACS Authentication on Cisco 3550 switch .It has Version 12.2(25)SEA IOS image. A strange thing is happening, whenver I am enabling AAA new-model on this switch, and then after enabling I see ruuning-config . It shows me this
* included here to hide the specific information I dint specified any RADIUS server , why it is showing me radius-server source-ports 1645-1646 after enabling AAA New-Model As soon as i give "no aaa new-model", this parameter also vanishes. I think this is the only reason I am not able to do tacacs authentication.
We have configured following commands on switch to fallback to local Vlan if both radius server (policy persona's) is found dead. For test purpose we shutdown both servers (policy persona's) but fallback didn't work. We have 3750 switch running image 12.2(55)SE6 having following configuration.We do not know whether we configured switch in proper way or do we need to modify it. [code]
Attempting to configure Linksys e4200 router in WPA2 Enterprise mode. Got this setup fine when using the Linksys WRVS4400N (That is until it died on me, RIP circa 2 months ago). I’m getting nothing in the NPS logs, nothing when doing a PCAP at the radius server. It appears this router isn’t communicating to the NPS/Radius server.
I am currently useing ACS 5.2 and have no problem using Tacacs+ with AD access.
But with Radius it seems I can only get the Local identity store to work, need to do something special to get Radius to work with active directory with Cisco ACS?
I have been trying to get our IPS (ASA-SSM-10 and 4260) to authenticate with Cisco Radius ACS 5.2 and they are not working. However, I was able to get them working with Microsoft Radius. Below is the logs from the IPS:
I need to configure RADIUS VSA configuration for a my alvarion device. Following are the attributes that need to be configured.
- Packet Data Flow ID (ID 1, integer16) - Direction (ID 4, integer8) - Transport Type (ID 6, integer8) - UplinkQoSID (ID 7, integer8) - DownlinkQoSID (ID 8, integer8)
[code]....
I was able to configure the first 6 attributes, how can I add the Sub - TLV's ClassifiedID, Priority, VLAN-ID and Classifier Direction which come under Classifier. Don't see any option for that in ACS 5.x
We have 2 ACS 4.2.1 servers in Windows 2003 with SP2 installed. We have updated the first ACS to the latest patches for Windows. After that we started having problems. CSRadius either stops by itself or when some time passes we get the following error in Failed attempts "Unknown error". When we restart the ACS services by the GUI, it resumes until the next time it stops.Do you happen to know if we have any bugs related to Windows patches?
I am trying to configure AAA authentication and authorization with Cisco 3725 (IOS 12.4(17)) for 802.1x and ACS 4.2 with VLAN assignment to my Windows XP client. (trying to assign VLAN 100 in my scenario).When user connects to the Router, it passes the authentication process (EAP-MD5). In my debug i see that Router recieves the Radius Attributes BUT does not apply anything!My running config:
Building configuration... Current configuration : 1736 bytes ! version 12.4 service timestamps debug datetime msec service timestamps log datetime msec
[code]......
As a result the vlan-switch data based does not change.
I have a questión about radius authenticaction with AD, when I log in into the network with user in AD and I make a mistake in password my radius authenticaction event in ACS 5.2 dont show me this logg. only show the authentication succeeded but dont show me the authentication failed. Maybe i must to enable same service to show the authentiaction failed. The Voice authetication works fine..

I want to add Radius attribute to Rad ware devices , so I will have the option to grant "read only" permission to users. as I understand I need to add VSA for the "read only" permission, or configure specific "Service-Type value 255"
in the following picture you can see the required information from Rad ware:
I am using the Self RADIUS server in my Cisco ACS SE 4.2 appliance S. I have an AAA client C that interacts with S by means of the RADIUS protocol. This works fine, in that S correctly carries out authentication chores on username/password (PAP and CHAP) pairs received from C, sending back to C the corresponding Access-Accept packet when the authentication succeeds, or Access-Reject when it doesn't.
I have been able to import a set of three VSAs into S. Each of those attributes is of string type. I then configured in S a single user U with password P so that, whenever a U/P pair received in S from C is authenticated by S, S should send back to C, in the Access-Accept packet, the three attributes with the following values: [code]
With this setup, when an authentication is successfully completed by S, C receives 53 bytes worth of data from S every time. I am attaching a typical example, already disassembled. I have disguised the actual vendor ID, for legal reasons, but the rest is exactly as it was when received in C.
According to the disassembly, what we got is an Access-Accept packet, as expected. Its length is 53 bytes - again as expected, for this is the only packet that C has received from S here. However, the packet is incomplete, for attribute #3 is missing its value field.
Looking into the whole packet in more detail, it can be seen that while the wire format for the first attribute, namely, Frame-IP-Address, is correctly constructed, the remaining are not. For example, the sequence of bytes corresponding to the attribute #1 reads 1a 09 00 00 xx xx 2c 61 62 63. I believe that this is incorrect; it should be 1a 0a 00 00 xx xx 2c 61 62 63, for the wire format for this attribute consists of 10, not 9, bytes. I tried a few variations on the values for the attributes, and the results are always substantially the same, in that the wire formats for these attributes are always incorrect.
This all probably implies I have done something wrong when importing the VSAs into S, and/or when configuring things on S. I am therefore attaching the csv files I used to import my VSAs into S; as before, names and vendor ID are disguised, but their lengths are exactly the same as in the undisguised file. I used two csv files: One to import the vendor ID, and the other to import the VSAs under that vendor ID. As for user U, in S's administration GUI I clicked on User Setup and selected user U, moved to the bottom of the screen, where the attributes for this particular vendor were present,introduced the values for each attribute mentioned above, and made sure that button in front of each attribute was ticked.
I need to add OPNET Radius attributes in ACS 4.2. How should I add a new VSA in ACS? The google search is pointing me to CSUtil.exe, and I cannot find this utility in the ACS install files. These are the values that I need added for OPNET. When configuring the RADIUS server to support the ACE Live Appliance, use the following Vendor Code and Vendor Specific Attribute (VSA): Vendor Code: 7119 VSA: 33.
When I upgraded my cisco 3750 ME from c3750me-i5k91-mz.122-46.SE to c3750me-i5k91-mz.122-58.SE2.bin all commands for radius disappeared? However, there are a lot of commands to ldap which was missing in the previous version. Seems as if the radius has disappeared and been replaced by ldap?
I am trying to configure ACS 5.1 to authenticate SSL VPNs on an ASA5500 and aslo to provide admin access to the ASA5500 both via radius.I want to authenticate the VPN against a SeureID appliance and the admin login against a different database (using internal for testing but will use LDAP in the end).I cant seem to get the ACS to distinguish between the two authentication types. If I create a rule that says match protocol radius I can point that at either database but if I try saying match radius and service type 5 it doesnt match the VPN and falls through to the default authentication service. I have also tried matching service type 6 for admin and that doesnt seem to work either.In the end what I want to acheive is to authenticate teh ASA5500 VPN against the SecureID appliance and then admin access to all devices on teh newtork (a mixture of Cisco, F5 and Juniper) to active directory via LDAP where if the user is a member of the "admin" group they get access.I was intending to use specific devices for the ASA5500s (there aretwo) and then creat a device group based on IP address range for everything else.
I am trying to authenticate on Juniper NSM express using cisco ACS 5.2. The request is arriving at the cisco ACS but i am getting the following error.RADIUS requests can only be processed by Access Services that are of type Network Access.
I have CISCO ACS 5.1 radius for VPN on ASA and tried to configure an NDG on it for AIRONET 1260 too and worked fine with IEEE 802.1x CISCO EAP-FAST authentication As I had some trouble to let users to authenticate only on VPN if are VPN users and only on CISCO AIRONET if need only WIFI AIRONET I tried exception policies rules but something not working. VPN was ok but not WIFI access denied for rule policy access I decided to install CISCO ACS 4.x on Windows 2003 that is on ACS 5 DVD I created NDG as done on ACS 5 put a shared secret , put on AIRONET too as done for ACS 5 but I receive an error against ACS 4.x To troubleshout it I tried [URL] but not work ! I think to have done all fine owever on ACS 5 it worked in 5 minutes I searched log inside ACS 4 and found "Invalid message authenticator in EAP request" and I found this: [URL]Changed shared secret more times but ever not workign with ACS 4 I need to have user and password prompt on client trying to authentincate on AIRONET WIFI and I need ACS INTERNAL USER no active directory, no LDAP , no external user database?
I am having ACS 4.0.2 in my network, which I want to use for 802.1x Radius Authentication for Clients on PEAP-MSCHAPv2 methodology.As per the documentation " EAP Authentication with RADIUS Server", Doc ID: 44844.I have configured Network Configuration and populated AAA client IP range and Secret Key.
Question1: Under Authenticate Using option, there are various RADIUS flavors available for selection. For a Non Cisco AAA client, should I select RADIUS IETF?
Question 2: In the above snap shot, It has an option called Global Authentication Setup, where we can setup EAP configuration. Under PEAP subsection there is an option to "Allow EAP-MSCHAPv2" check box.After checking that, is a restart required to the ACS Server? Would it cause any disruptions to the existing services on the ACS?
I am trying to move my ISDN dialup branches authentication/authorization from old ACS 4.1 to ISE appliance. Before it was through ACS 4.2 with TACACS protocol but now since we are moving to ISE we are moving them to ISE with radius.
Problem is that isdn client gets authenticated and authorized but calls get dropped and they dont able to communicate with HO. IP address is assigned by Head End router to all remote isdn dialing branches..
I have used default "PermitAccess" in authorization policy and authentication policy is also default. I dont understand where I am going wrong as authentication and authorization is sucessful.

how to setup ACS 5.3 to authenticate wireless users over radius? I currently have the SSID pointing to a Microsoft IAS server and would like to move the authentication to be done via ACS.
