Cisco ISE - Reauthentication of client if server becomes alive again
Dears,
I have this case where Cisco ISE server is used to authenticate & authorize clients on the network.
I configured the switch port to authorize the client in case the ISE server is dead (or not reachable).
The thing is that I want to reauthenticate the client once the ISE server becomes alive again but I am not able to.. ("Additional Information is needed to connect to this network" bullet is not appearing and the client PC remains authenticated and assigned to the VLAN.
Below is the switch port configuration:
interface FastEthernet0/5
switchport access vlan 240
switchport mode access
switchport voice vlan 156
authentication event server dead action authorize vlan 240
authentication event server alive action reinitialize
authentication host-mode multi-domain
authentication order dot1x mab
authentication priority mab
authentication port-control auto
mab
dot1x pae authenticator
spanning-tree portfast
Anyone can help?
Regards,
Please check whether the switch is dropping the connection or the server.
Symptoms or Issue
802.1X and MAB authentication and authorization are successful, but the switch is dropping active sessions and the epm session summary command does not display any active sessions.
Conditions
This applies to user sessions that have logged in successfully and are then being terminated by the switch.
Possible Causes
•The preauthentication ACL (and the subsequent DACL enforcement from Cisco ISE) on the NAD may not be configured correctly for that session.
•The preauthentication ACL is configured and the DACL is downloaded from Cisco ISE, but the switch brings the session down.
•Cisco ISE may be enforcing a preposture VLAN assignment rather than the (correct) postposture VLAN, which can also bring down the session.
Resolution
•Ensure the Cisco IOS release on the switch is equal to or more recent than Cisco IOS Release 12.2.(53)SE.
•Check to see whether or not the DACL name in Cisco ISE contains a blank space (possibly around or near a hyphen "-"). There should be no space in the DACL name. Then ensure that the DACL syntax is correct and that it contains no extra spaces.
•Ensure that the following configuration exists on the switch to interpret the DACL properly (if not enabled, the switch may terminate the session):
radius-server attribute 6 on-for-login-auth
radius-server attribute 8 include-in-access-req
radius-server attribute 25 access-request include
radius-server vsa send accounting
radius-server vsa send authentication

Cisco ISE 1.2, Clients not getting IP address in closed mode
Hello, I am running closed mode on my switchports. I have an issue where some clients come in in the morning, try to login, and will not get network access. I see that this is because they do not get an IP address. I am using MAB for authentication currently. They appear to MAB correctly and get Authorized in ISE, but they do not get an IP. Therefore, they also do not get the DACL of permit ANY. It's like the port gets de-authenticated during the night. Usually when the machine is rebooted it will come up with an IP address. Here is my switchport config...
switchport access vlan 32
switchport mode access
switchport voice vlan 64

Cisco ISE 802.1X Client Provisioning
Hi,
I have a requirement for ISE client provisioning for both Windows and mac. I have the following setup:
1. 2 SSIDs, Guest and Employee
2. Guest is open access
3. Employee is 802.1x eap-peap (username/password)
I was wondering if client local administrator privillege is required for 802.1x provisioning for windows client? I believe it is required for MAC OS however not too sure if it may be required for Windows?
Example Employee A connect to Guest SSID and is redirect to the guest web portal. Upon login, they will be presented with the device registration portal. Upon being presented by the ISE on the supplication wizard, will they be requested for local administrator/domain admin privillege to install the supplicant wizard package/provisioning agent successfully?
Any suggestion is appreciated.
Thanks.Hi,
Appreciate for the feedback.

Cisco ISE authentication failed because client reject certificate
Hi Experts,
I am a newbie in ISE and having problem in my first step in authentication. Please help.
I am trying to deploy a standalone Cisco ISE 1.1.2 with WLC using 802.1x authentication. The user authentication configured to be checked to ISE's internal user database for early deployment. But when the user try to authenticate, they failed with error message in ISE :
Authentication failed : 12321 PEAP failed SSL/TLS handshake because the client rejected the ISE local-certificate
I've generate a certificate for ISE using Windows Server CA and replace ISE's self-signed certificate with the new certificate but authentication still failed with the same error message. Must I generate a certificate for WLC also? Please help me in solving this problem.
Regards,
RatnaCertificate-Based User Authentication via Supplicant Failing
Symptoms or
Issue
User authentication is failing on the client machine, and the user is receiving a
“RADIUS Access-Reject” form of message.
Conditions (This issue occurs with authentication protocols that require certificate validation.)
Possible Authentications report failure reasons:
• “Authentication failed: 11514 Unexpectedly received empty TLS message;
treating as a rejection by the client”
• “Authentication failed: 12153 EAP-FAST failed SSL/TLS handshake because
the client rejected the Cisco ISE local-certificate”
Click the magnifying glass icon from Authentications to display the following output
in the Authentication Report:
• 12305 Prepared EAP-Request with another PEAP challenge
• 11006 Returned RADIUS Access-Challenge
• 11001 Received RADIUS Access-Request
• 11018 RADIUS is reusing an existing session
• 12304 Extracted EAP-Response containing PEAP challenge-response
• 11514 Unexpectedly received empty TLS message; treating as a rejection by the
client
• 12512 Treat the unexpected TLS acknowledge message as a rejection from the
client

• 12153 EAP-FAST failed SSL/TLS handshake because the client rejected the
Cisco ISE local-certificate
• 11504 Prepared EAP-Failure
• 11003 Returned RADIUS Access-Reject
Note This is an indication that the client does not have or does not trust the Cisco
ISE certificates.
Possible Causes The supplicant or client machine is not accepting the certificate from Cisco ISE.
The client machine is configured to validate the server certificate, but is not
configured to trust the Cisco ISE certificate.
Resolution The client machine must accept the Cisco ISE certificate to enable authentication. -
Cisco ISE: External RADIUS Server
Hi,
I would like to forward RADIUS from PSN to another PSN. I already defined "External RADIUS Servers".
So, how can I use this external RADIUS server to process my request ?
Looking at the user guide but didn't find any information about this setting (For rule based not simple rule)
If anyone use this, please suggest this to me.
Thanks,
PongsatornDefining an External RADIUS Server
The Cisco Cisco ISE can function both as a RADIUS server and as a RADIUS proxy server. When it acts as a proxy server, the Cisco Cisco ISE receives authentication and accounting requests from the network access server (NAS) and forwards them to the external RADIUS server. The Cisco Cisco ISE accepts the results of the requests and returns them to the NAS. You must configure the external RADIUS servers in the Cisco Cisco ISE to enable it to forward requests to the external RADIUS servers. You can define the timeout period and the number of connection attempts.
The Cisco Cisco ISE can simultaneously act as a proxy server to multiple external RADIUS servers. You can use the external RADIUS servers that you configure here in RADIUS server sequences. This External RADIUS Server page lists all the external RADIUS servers that you have defined in Cisco Cisco ISE. You can use the filter option to search for specific RADIUS servers based on the name or description or both.
To create an external RADIUS server, complete the following steps:
Step 1 Choose Administration > Network Resources > External RADIUS Servers.
The RADIUS Servers page appears with a list of external RADIUS servers that are defined in Cisco ISE.
Step 2 Click Add to add an external RADIUS server.
Step 3 Enter the values as described:
•Name—(Required) Enter the name of the external RADIUS server.
•Description—Enter a description of the external RADIUS server.
•Host IP—(Required) Enter the IP address of the external RADIUS server.
•Shared Secret—(Required) Enter the shared secret between Cisco Cisco ISE and the external RADIUS server that is used for authenticating the external RADIUS server. A shared secret is an expected string of text that a user must provide to enable the network device to authenticate a username and password. The connection is rejected until the user supplies the shared secret. The shared secret can be up to 128 characters in length.
•Enable KeyWrap—This option increases RADIUS protocol security via an AES KeyWrap algorithm, to help enable FIPS 140-2 compliance in Cisco ISE.
•Key Encryption Key—This key is used for session encryption (secrecy).
•Message Authenticator Code Key—This key is used for keyed HMAC calculation over RADIUS messages.
•Key Input Format—Specify the format you want to use to enter the Cisco ISE FIPS encryption key, so that it matches the configuration that is available on the WLAN controller. (The value you specify must be the correct [full] length for the key as defined below—shorter values are not permitted.)
–ASCII—The Key Encryption Key must be 16 characters (bytes) long, and the Message Authenticator Code Key must be 20 characters (bytes) long.
–Hexadecimal—The Key Encryption Key must be 32 bytes long, and the Message Authenticator Code Key must be 40 bytes long.
•Authentication Port—(Required) Enter the RADIUS authentication port number. The valid range is from 1 to 65535. The default is 1812.
•Accounting Port—(Required) Enter the RADIUS accounting port number. The valid range is from 1 to 65535. The default is 1813.
•Server Timeout—(Required) Enter the number of seconds that the Cisco Cisco ISE waits for a response from the external RADIUS server. The default is 5 seconds. Valid values are from 5 to 120.
•Connection Attempts—(Required) Enter the number of times that the Cisco Cisco ISE attempts to connect to the external RADIUS server. The default is 3 attempts. Valid values are from 1 to 9.
Step 4 Click Submit to save the external RADIUS server configuration. -
Cisco ISE 1.2 and AD Group
Hello,
I have Cisco ISE installed on my EXSi server for my test pilot. I have added several AD groups to ISE as well.
I have created an Authorization policy condition, which is WIRELESS_DOT1X_USERS (see screenshot)
Basically, I just duplicated the default Wireless_802.1X and added Network Access:EapAuthentication, Equals, EAP-TLS.
My problem is, I was unable to join the wireless network if I added my AD group to the Authorization policy (see screenshot). The user that I have is a member of WLAN-USERS. If I removed the AD group from the Authorization policy, the use is able to join the wireless network.
I attached the ISE logs screenshot as well. I checked the ISE, AD/NPS, WLC, laptop time and date, and they are all in synched.
I also have the WLC added as NPS client on my network.
I checked the AD log and what I found was the WLCs local management user trying to authenticate. It is supposed to be my wireless user credential not the WLC.
This is the log that I got from the AD/NPS
Network Policy Server denied access to a user.
Contact the Network Policy Server administrator for more information.

I got my AD group working. What I did, I checked the user's certificate that is installed on the laptop then modified the ISE certificate authentication profile to "Subject Alternative Name". I had the ISE set to common name when I was having an issue.
I forgot to mentioned that I have to servers in my ISE test pilot. I have AD with NPS, and CA. These servers are Windows 2008 R2.
I am a little confuse about the attribute in certificate template you have mentioned. Is that located at Certificate Authority/server-name/Certificate Templates/Users? I am not sure where to look for that attribute on the CA server. -
Cisco ISE Deployment suggestion required
Require Assistance on Cisco ISE Deployment for below scenario
-- We have Three Cisco ISE Appliances and Client has taken Advance Subscription License for 500 users
-- Client has DC & DR and needs to deploy the Cisco ISE in one Main Office which connects to DC & DR on MPLS Links
-- Client suggestion was to deploy one ISE node ( Admin + M&T + Policy Server ) in DC and its Standby Secondary in DR
and only deploy Policy Server in Main Office.
Idea behind the design is that ,
1) If DC fails , Cisco ISE related logs will get generated on DR and any Cisco ISE related request will be taken care by Local Policy Server in Main Office .
2) If Local Policy Server Fails , then ISE node in DC will act as Secondary backup and DR will act Teritary Backup
below is view
DC
Primary Node with Role
[Admin , M&T , Policy Server]
Main Remote Offic

Is OpenLdap supported by Cisco ISE 1.2?
When I try "Test bind to server" I get results so the connection seems fine. However when I set up the policies for a basic wlan with wpa2 authentication it says "Invalid password". When I put my username in the attributes folder it finds my id so I'm sure the link is working fine.Cisco ISE always uses the primary LDAP server to obtain groups and attributes for use in authorization policies from the Admin portal, so the primary LDAP server must be accessible when you configure these items. Cisco ISE uses the secondary LDAP server only for authentications and authorizations at run time, according to the failover configuration.
Cisco ISE retains a list of open LDAP connections (including the binding information) for each LDAP server that is configured in Cisco ISE. During the authentication process, the connection manager attempts to find an open connection from the pool. If an open connection does not exist, a new one is opened.
If the LDAP server closed the connection, the connection manager reports an error during the first call to search the directory, and tries to renew the connection. After the authentication process is complete, the connection manager releases the connection.

Cisco ISE AD (Windows Server 2013) Authentication Problem
Background:
Deployed two Cisco ISE 1.1.3. ISE will be used to authenticate wireless users, admin access to WLC and switches. Backend database is Microsoft AD running on Windows Server 2012. Existing Cisco ACS 4.2 still running and authenticating users. There are two Cisco WLCs version 7.2.111.3.
Wireless users authenticates to AD through ACS 4.2 works. Admin access to WLC and switches to AD through ISE works. Wireless authentication using PEAP-MSCHAPv2 and admin access wtih PAP/ASCII.
Problem:
Wireless users cannot authenticate to AD through ISE. The below is the error message "11051 RADIUS packet contains invalid state attribute" & "24444 Active Directory operation has failed because of an unspecified error in the ISE".
Conducted a detailed test of AD from ISE. The test was successful and the output seems all right except for the below:

Action Taken:
Log on to Cisco ISE and WLC using AD credentials. This rules out AD connection, clock and AAA shared secret as the problem.
2) Tested wireless authentication using EAP-FAST but same problem occurs.
3) Detailed error message shows the below. This rules out any authentication and authorization polices. Before even hitting the authentication policy, the AD lookup fails.

4) Enabled AD debugging logging and had a look at the logging. Nothing significant and no clues to the problem.
5) Tested wireless on different laptos and mobile phones with same error
6) Delete and add again AAA Client/Devices on both Cisco ISE and WLC
7) Restarted ISE services
8) Rejoin domain on Cisco ISE
9) Checked release notes of ISE 1.1.3 and WLC 7.2.111.3 for any open caveats. Nothing found related to this problem.
10) There are two ISE and two WLC deployed. Tested different combination of ISE1 to WLC1, ISE1 to WLC2 etc. This rules out hardware issue of WLC.
Other possibilities/action:
1) Test it out on a different WLC version. Will have to wait outage approval to upgrade WLC software.
2) Incompatibility of Cisco ISE and AD running on Microsoft Windows Server 2012
Anyone out there experienced something similar of have any ideas on why this is happening?
Thanks.
Update:
1) Built another Cisco ISE 1.1.3 sever in another datacentre that uses the same domain but different domain controller. Thais domain controller is running Windows Server 2008. This works and authentication successful.
2) My colleague tested out in a lab environment of Cisco ISE 1.1.2 with Windows Server 2012. He got the same problem as described.
This leads me to think there is a compatibility issue of Cisco ISE with Windows Server 2012.Does anyone know if ISE 1.1.3 p1 supports AD DCs running 2012, if not which patch is required ot version?
Worryingly when ISE joins a 2012 DC it states it's connected successfully, and if another 2003 DC is available in that datacentre it will perform the auths against that DC whilst actually advertising (Connections in the GUI) that it's connected to the 2012 DC. We ended up mapping 8 PSN IP’s to another datacentre which has one Win2003 servers whilst the old 2003 DC is being promoted back, the 8 ISE servers started working, even though they still advertised they were connected to the 2012 DCs in the original datacentre - I performed a leave and join on one PSN and only then did it advertise that the node was connected to a DC in a different datacentre -
Hi!!
We are working on a mapping between a Sponsor Group in Cisco ISE and a user group in Active Directory....but the client wants the mapping to be through a RADIUS SERVER, for avoiding ISE querying directly the Active Directory.
I know it is possible to use a RADIUS SERVER as an external identity source for ISE.....but, is it possible to use this RADIUS SERVER for this sponsor group handling?
Thanks and regards!!Yes It is possible to map Sponser group to user group in AD and if you want to know how to do please open the below link and go to Mapping Active Directory Groups to Sponsor Groups heading.

Hiee,
I am using cisco anyconnect secure mobility client, version - 3.1.05170 , in my windows 8.1 PC to access vpn to my office desktop. But as soon as i connect cisco anyconnect client, my wifi networks becomes limited or unavailable. Thus, i am not able to get remote access to my office desktop. And not even able to access any other websites also. But as soon as i disconnect from the cisco anyconnect vpn client, every thing becomes normal, and the exclamation mark from the network icon also disappears.
kindly help me in this regard.
Thanks and regards
NeerajThere are a few things to consider here:
- The IPSec VPN client is EoL, so even if we consider this as a bug, it wouldn't be fixed
- fixing the file server access would break the DHCP renew which means there is no completely clean way to fix this, at least not at the IP level since the client can't route to the same destination using 2 different paths.
Is there any chance we could do a static policy NAT for the DHCP traffic so it appears to come from another IP? It's twisted and it may not work (the client might use the DHCP server IP embedded inside the payload and not the source IP) but if it does, then we'd fix the overlap.
Could the server use another IP address for the DHCP service (much like using a loopback for a certain service on a router?)
A third solution would be to NAT the destination server IP on the ASA for traffic from the IP pool going to the server. We'd need DNS doctoring as well to resolve the server's name to the NATted IP. This way the server would appear from the VPN client as being at a different IP, thereby fixing the overlap.
All these potential solutions are quite involved... you may be better off wityh a simpler design: splitting of your server into 2 or using something else to do DHCP for the VPN clients. -
Cisco ISE with both internal and External RADIUS Server
Hi
I have ISE 1.2 , I configured it as management monitor and PSN and it work fine
I would like to know if I can integrate an external radius server and work with both internal and External RADIUS Server simultanously
So some computer (groupe_A in active directory ) will continu to made radius authentication on the ISE internal radius and other computer (groupe_B in active directory) will made radius authentication on an external radius server
I will like to know if it is possible to configure it and how I can do it ?
Thanks in advance for your help

BlaiseCisco ISE can function both as a RADIUS server and as a RADIUS proxy server. When it acts as a proxy server, Cisco ISE receives authentication and accounting requests from the network access server (NAS) and forwards them to the external RADIUS server. Cisco ISE accepts the results of the requests and returns them to the NAS.

The External RADIUS Server page lists all the external RADIUS servers that you have defined in Cisco ISE. You can use the filter option to search for specific RADIUS servers based on the name or description, or both. In both simple and rule-based authentication policies, you can use the RADIUS server sequences to proxy the requests to a RADIUS server.
The RADIUS server sequence strips the domain name from the RADIUS-Username attribute for RADIUS authentications. This domain stripping is not applicable for EAP authentications, which use the EAP-Identity attribute. The RADIUS proxy server obtains the username from the RADIUS-Username attribute and strips it from the character that you specify when you configure the RADIUS server sequence. For EAP authentications, the RADIUS proxy server obtains the username from the EAP-Identity attribute. EAP authentications that use the RADIUS server sequence will succeed only if the EAP-Identity and RADIUS-Username values are the same. -
Cisco ISE (1.3) Posture without Client Provisioning
Hello readers,
Is it possible to set up Cisco ISE with posture without Client Provisioning?
My customer deploys the NAC Agent via MS SCCM. We prefer a access accept + DACL during the pending state instead of redirecting to client provisioning. But the NAC Agent will only communicate when we redirect to client provisioning.
Regards,
DennisWith ISE you can perform 802.1x first and after that optionally you can perform posture. This is done with Radius, that's why it's really and completely out of band, and there's no such concept of trusted or untrusted port because the traffic is never inline.
Still, with ISE you have another option of "inline Posture", in which there's trusted and untrusted ports. I guess that's for some specific cases in which you can't go out-of-band.
On the other hand, so called "out-of-band" NAC was really always an inline solution, only after the user has authenticated and security policies have been verified then the user goes "out-of-band". -

Cisco ISE and external syslog server
Hi Security Experts,
We are starting with deploying cisco ISE (Identity Services Engine) in our network. We have allocated 250GB space for (Admin+Monitor) ISE node.
I want to know if we can send the logs from monitoring node to external syslog server after a defined time interval.
For example, logs which are more than 10 days old should be sent to external syslog server. So basically our monitoring node will have logs which are at the max 9 days old. Is it possible? Could you point me to some doc which explains configuration of the same?
Thanks,
KashishNo this isnt possible via syslog. What you are looking for is database purging, so that the monitoring database is purged after a specific time interval. Here is a guide that will help shed some light on this:
