Cisco AAA/Identity/Nac :: 802.1x / Does Authentication Process Done After Completing Profiling
Nov 30, 2012
I have two questions about ISE Profiling features .
•1) Does Authentication Process done after completing profiling ?
•2) Can profiling feature overcome mac spoofing issue (printer mac is used with static IP to access the network where user and printer are in same vlan ,user with 802.1x and printers with MAB auth) and deny windows user with spoofed printer mac and IP add?
how profiling works exactly ?How intelligent is the profiling engine, meaning: Will it discover that one device has more than one different MACs and will merge the entries in the database ??
Example:This is in fact the same device, there is only one WLC-2500 in the network ....If it can discover that, what needs to be configured on the ISE to do that ?
We currently have an issue with our main ISE. When logged in using the admin account (member of superadmin group) we no longer see the Profiling button/menu and also missing oter options in the GUI. On another standalone ISE we do see al those options?
Both are running on the same software version 1.1.1.268.We are using ISE 3395-K9 appliances
We have integrated WLC 5508 to cisco ise 3315 with ios 1.1.1 and using Guest Sponsor portal for wireless guest users.Where we have created open ssid in wlc and redirect web login portal in wlc for guest users. We have enable all respective node in policy service for profiling and also configure snmp in wlc as well as in ise.
When guest user is connected to open ssid its get redirected to web login page of ise portal and when it gets login we are only able to see the username which guest user login but not the end device in monitoring log.
Wireless End devices are not able to get profiled can any one tell me what configuration I need to do on ise or wlc side to profiled end guest wireless device like android,iphone and laptops
i have a problem with 1552E to register with 5508 WLC, and always got "AAA authentication error” in the WLC log, while AAA is not enabled. so my question is , do i need to add the MAC address to the WLC MAC filter list even if i not enable the AAA server in the WLC.

I am working on implementing ACS appliances. All working ok, until I try to add an attribute to the Shell profile (priv-lvl = 15). When I do this, the runtime process shutsdown (on both primary and secondary devices) and no further device authentications can be made. I can reinitialise the database without issue at the moment, but I'd like to know what causes this and how to prevent from happening in the future - when the database will becoem much more critical.Do I need to raise a TAC case?
I have two core switches - 4506E, and i noticed there are frequent cpu spikes on both of the cores switches. As its spikes intermitendly i couldnt able to anlyze the issue. I need inputs on the following,
1) Is there any Free CPU process monitoring tools to identify which process is spiking ?
2) Troubleshooting techniques to identify the issue.
I configured before ACS v4.2 to authenticate network devices using internal users at first, and if the user is not found use AD list users. But with v5.3 I have some problems doing this, on identity policies I use rule based result selection option, I configured 2 polices for Identity source, one for Internal Users and other policy for AD user, but it only works with the first policy, internal users or AD, but works only for the first policy identity. how to do that, if the user is not found on first policy, continue to the next policy.
I need a specify users to allow access to particular devices and give privilege only for show command or show run. Here is how I tried to configured.
1. Configured two seperate Shell Profile and Command set with privilege level 4-5 and allowing only show run command
2. create seperate service selection rule with adding the require NDG and protocol TACACS and maching service "RestrictAccess"
3. In the RestrictAccess Service I have following configured; Identity: internal users, Group Mapping to a particular group where the user exists, authorization: matching the above created identity group, NDG, shell profile, command sets
All the steps are attached in the .doc file. However when I tried with the particular user he is able to access everything and he is not hitting the correct access rule.
after upgrading to 7.4.100.0 im getting this error message when trying to apply changes on the wlan id."mDNS profiling cannot be enabled with flexconnect local switching"if unselect mDNS snooping under (wlan id/advanced) i can apply the changes, but only temporary.when im looking the next time, the tick box mDNS snooping is enabled again.is this a bug or what?
In order to restrict access to websites on our internal network, would we be able to put an ASA in front of the web server and force users to authenticate through the ASA and, once authenticated, allow only port 80 or 443 traffic for that use? The ASA would query the ACS 5.1 server for authentication/authorization using AD as the identity store. Is this even possible with TACACS?
My customer has a large installed base of MACs, all connected via controller-based (5508) WLAN. He wants to grant access to the network based on the device's mac addresses and move the WLAN-clients to a specific VLAN.I added all devices with their mac addresses to the ACS internal identity store for hosts.According to the following message the client sends the user-login credentials (chegger) within the RADIUS-request instead of the clients mac address and of course it has to fail. After many configuration changes, I ended up always with the same result.
I have question on EAP-TLS with ACS 5.2. If I would like to implement the EAP-TLS with Microsoft CA, how will the machine and user authentication take place? Understand that the cert are required on both client and server end, but is this certificate ties to the machine or ties to individual user?
If ties to user, and I have a shared PC which login by few users, is that mean every user account will have their own certificates?
And every individual user will have to manually get the cert from CA? is there any other method as my environment has more than 3000 PCs.
And also if it ties to user, all user can get their cert from CA with their AD login name and password, if they bring in their own device and try to get the cert from CA, they will be able to successfully install the cert into their device right?
I have a new ACS 5.3 installation which I have joined to our AD Domain and added the directory groups into. I have also added all our devices into ACS and their groups etc but I am still only able to authenticate on the our switches with an internal ACS account, when I try with an external AD account the log shows the following error "Subject not found in the applicable identity Store (s)"
We got recently a Cisco Secure ACS 1120 and i upgraded the Appliance to 5.1 from 5.0 with all your support
Now I need to integrate Cisco ACS 5.1 with RSA Authentication Manager 6.1 . I Successfully Downloaded config file from RSA ACE Server and exported into ACS 1120.
I also Added ACS as a NetOS Agent in the RSA Server , during the process i found few warnings . The ACE Server is not able to Resolve the IP Address to NAme ( DOes it Necessary ?? ).
I havent created any secret Key file for communication between ACS and RSA and encryption i used is DES.
Now when I log into ACS and search for Devices in the Identity Store Sequences i am not able to Look for RSA Token Sever .
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:
If laptop/desktop goes on sleep mode or keep connected with interface configured for 802.1X for more than 12 hours it does not work or not connect to Exchange server, Cisco ISE console, office communicator..for re authentication i need to restart PC/ Laptop or unplug and replug lan cable from it!but before restarting i am able to ping all DNS, DHCP, OCS, everything..[code]
I need to limit to some AD groups, authentication with ACS 5.3.For example, i need that only users os somedomain.com/users/test1 are authenticatet via ACS --> ADS.
I have a Cisco ASA (8.2) setup with remote access for my users using Cisco VPN client. The authentication is passed off to my ACS 5.3 which then checks with AD. What I've done so far is create Access Policy rule where I define specifically the Location and NDG where the ASA is and then a DenyAllCommands command set. This should pass authentications just fine but this also gives those users the ability to remote connect directly into the ASA and login successfully. Even though there is a Deny Commands there I still would prefer they get Access Denied as a message. If I do a Deny Access on the ShellProfile then this stops the login authentication altogether.
We would like to enable ACS authentication to login to different routers (Cisco 881s) we got that are interconnecting with our WAN via VPN tunnels. We would like to avoid using public IP for the router to communicate and relay user/password info with the ACS server and rely on the server's private IP instead. The problem is that all the router's outside interfaces connect to the Internet using public IPs and when the router wants to communicate with the ACS server it will use its public-facing interface IP and that'll fail. We can ping the server obviously when we set the source to the internal LAN IP.
The question is is there a way to have the router communicate with ACS across the VPN tunnel using its private IP?

I have a dot1x client with client certificate working well with my ACS 5.2 and EAP-TLS. Now I would like to configure the Re-Auth periode on the ACS 5.2, I did the following:
1. Configure a Access Profile with Reauthentication Timer = static and 30 seconds (see attachment ACS1.png and ACS2.png)
2. Enabled authentication periodic and authentication timer reauthenticate server on switchport
i am evaluating ACS 5.3 with an ASA5505, by using password management in the IPSec tunnel config i am able to authenticate the VPN clients using mschapv2, however, the SSH sessions are authenticated using PAP
I have looked for days and days for an answer without success, is this by design?
Cisco documents state that SSH can be authenticated via TACACS with PAP,CHAP or MSCHAPv1, however, It seems to be default to PAP
From Cisco Doc: TACACS+ Server Support # The security appliance supports TACACS+ authentication with ASCII, PAP, CHAP, and MS-CHAPv1
I am getting ready to install a new ACS 5.1 server to replace my current 4.1 acs box. I wanted to start off with a fresh install rather than upgrading all of my 4.1 data.
Can I have devices (ASA for VPN authentication, routers & switches for user authentication) use both for authentication while I get all the users configured in the new box?
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 configured ACS 5.3 and added AAA clients with TACACS+ server and shared secret key as cisco123. i did the below config on switch also. when i try to authenticate login with ACS it does not respond. Find the configuration and debug output.nd
In debug output it gives ruser and rem_addr is null. i did not understand why .
I am able to ping to ACS server and i used telnet 192.x.x.10 49 and it gives the proper output.

I notice 8.4(4) now has public key authentication (just like IOS - yay!) and found a couple of issues: The CLI config guide [URL] states incorrect syntax for adding the public key to the ASAThere is an undocumented ASA limit on the public key size supported
I have several devices on the same subnet and with similar configuration. All of them were entered manually on the ACS server and are configured to authenticate using TACACS+. Some of the devices can authenticate ok, but other will timeout. I did a tcpdump on the firewall port and can see the device sending the SYN to the ACS server but the server sends no reply to the device.
I am using Cisco ACS 5.1. I would like to authenticate my ip phones with mab (Avaya phones) and the commputers with dot1x.Everything works fine except that the phones which are successfully authenticated with mab tries to authenticate again and again and again ... and this fills up the ACS logs. Every authentication is successfull and the phone does not hang up. But this fills up my logs and makes them unusefull.
I am in the process of migrating from ACS 4.1.1.23 to ACS 5.4.I have migrated our users and Network Device Groups and configured external Identity stores like AD and RSA.I want to authenticate our Wireless users with AD and VPN users through RSA.I am unable to create policies to get this UP and working.
Currently I am running Cisco ACS 3.2 ,now wanted to upgrade with the latest version along with the Authentication using AD , process/Document to upgrade the same .
I have configured the cisco 2960 switch with AAA & the radius server is free radius. I am able to login into the switch when radius server is working.But when radius server is not reachable, in that particular condition the switch doesn't move to local authentication configured on the switch.
