ISE Authorization PermitAccess - EPM-HOLE-ACL
Hello,
I have a 6509 switch that is running 12.2(33) SXI9 code that has a unique issue. When the client connects they are authenticated and match an authorization profile that gives the default PermitAccess. Unfortunately at this point the client can only access what it is allowed in the ACL-DEFAULT.
When I look at the logs I see:
Mar 27 18:14:02 EDT: %EPM-6-POLICY_APP_SUCCESS: IP aa.cc.dd.ee | MAC 001a.1111.2222 | AuditSessionID AC10FB8A0000007101BDF21B| AUTHTYPE DOT1X| POLICY_TYPE Named ACL| POLICY_NAME EPM-HOLE-ACL| RESULT SUCCESS
What is this Named ACL EPM-HOLE-ACL? This ACL is not defined in ISE or the switch.
Kyle,
I do not know what the EPM-HOLE-ACL but found it a little comical. However, this is true that you have to apply another dacl to override the acl default which is applied on the port. Keep in mind you will also run into this issue if you decide to (i am basing this off the 2k 3k behavior) set a guest vlan if the radius server is dead, because of this default ACL the users will not be able to get anywhere outside of that acl.
There is a feature enhancment in the works to provide an acl if radius server is dead or when authentication fails...etc. However I think this ties all back into to your question, that if there isnt a dacl assigned to override the port acl then this seems to be the behavior.

Hey guys,
I have a question regarding ISE Authorization Policy. In my test lab, I don't have any wired station, and what I have is a wireless lapotp. I have configured to allow only EAP-TLS authentication. Now, my problem is I keep getting "15039 Rejected per authorization profile."
Under the Policy > Authorization, I created a rule where I just want to allow on EAP-TLS either via machine or user identity, and the bottom is the default DenyAccess. When I tried to join the wireless network, I kept getting denied. I checked the ACL counters on the WLC side and it was not increasing.
I changed the default DenyAccess to PermitAccess, and I was able to join the wireless network no problem, and the ACL counters on the WLC side increased.
It seems like I am hitting the default Authorization Policy first which is on the bottom of the authorization policy.
I attached the failed and authenticated logs that I got from ISE.
Has anyone have encoutered this issue?
The version that I have is 1.1.1
Thanks
P.S.
I went back to check my autorization condition, and it is blank (See the 1st screenshot)Hi,
it is obvious that you are not matching any condition.
rather than keeping the condition blank, fill it with a condition that is always match and try if that helps.

Hi All
Has anyone successfully used a Guest Role in an ISE authorization policy?
I'm using 2 different Guest Roles that get assigned by the Sponsor on the account creation page.
I want to differentiate between the 2 roles in my authorization policies to ensure separation between the 2 types of user.
I've had a suggestion to use an Option field on the sponsor's account creation page - this will work but it would be more secure if the Guest Role could be used.
ISE version is 1.2.198.0
Regards
RogerExactly.
If I create a sponsored account I can use the credentials to authenticate to either SSID.
Similarly if I create a self-registered account I can use the credentials to authenticate to either SSID.
The correct policy set is selected each time based on the SSID.
It seems to me as if the guest roles effectively do nothing and that all users get assigned to a single group. Of course, as an administrator you simply can't ever see the accounts and where the user has been assigned to. Any attempts to differentiate based on the group simply fail.
It looks like the assignment of a guest role for self-registration is actually a global setting that is applied to all portals and therefore over-rides the guest role assigned within the sponsor group settings. See the attached image. -
MSE-provided location used with ISE Authorization Profile
Hello Everyone,
Can MSE-provided location be used in an ISE Authorization Profile?
Thanks much,
David D.Yes, ISE 1.2 can used this feature if it is used with Merridian or Ironmobile integration. and This is still in Road Map.

ISE Authorization Policy Issues
Hello Team,
I´m getting troubles during my implementation: The User PC never gets IP Address from Access VLAN after AuthZ Policy succeded.
I have two vlans in my implementation:
Vlan ID 802 for Authentication (Subnet 10.2.39.0)
Vlan ID 50 for Access Users (Subnet Y.Y.Y.Y)
When I start my User PC, I get IP for VLAN 802 (10.2.39.3) and After Posture process, ISE inform the switch to put the User PC port in VLAN 50.
Here I have my Switch Port Configuration:

Could you help me in this Case ?
Best Regards,
Daniel StefaniIt seems like the PC is operating in the VOICE-domain according to the cmd auth sess int you showed. Do you think that has something to do with your problem? I've experienced some PC's having problem with that.
If you could, try getting the PC to operate in the DATA-domain by not sending the voice-attribute from ISE after the authorization. -
ISE - Authorization Profile issue
I'm running a trial of ISE and I'm attempting to create the authorization profile with the following settings:
Name: Posture_Remediation
Access Type: Access_Accept
Common Tools:
Posture Discovery, Enabled
Posture Discovery, ACL ACL-POSTURE-REDIRECT
The documentation says Common Tools, but in the screen shot it shows Common Tasks which is accurate to my install. Doc: http://www.cisco.com/en/US/products/ps10315/products_tech_note09186a0080bba10d.shtml#topic19
The issue is that I do not see a Posture Discovery option in the Common Tasks area. Can I add these the attributes using the Advanced Attributes settings or is there something I need to enable to display the Posture Discovery option within Common Tasks?
Any help would be appriceated.
AndrewHello Andrew,
As per your query i can suggest you-

ISE Authorization Profile Question
Hi,
We are implementing ISE at a university and using dynamic VLAN allocation to segment the traffic into vlans of a manageable size - we do not want to use geographically based vlans for a number of reasons. However there is one scenario which I am struggling with.
A number of students will be living in university owned houses which are not directly connected to the university network. In these houses an ISP will provide an ADSL circuit. These ADSL circuits will be aggregated back at the university data centre and will connect down one piece of wire to the university network. I haven't completed my testing yet but the general theory is that we can use multi-auth to allow them on to the network and apply appropriate access restrictions (these restrictions will differ from those applied to those applied when they connect "on campus") . However, in order to do this, I will need to create an authorization policy based on where they are coming from (ie what switch and what port). I can see how I can use Identity Groups to identify which switch the traffic is coming from but for the life of me I have no idea how I would identify the port.
Anyone have any ideas how I might achieve my goal?
Thanks
AlanHi
Cisco ISE allows for a wide range of variables within authorization policies to ensure that only authorized users can access the appropriate resources when they access the network. The initial release of Cisco ISE supports only RADIUS-governed access to the internal network and its resources. The authorization policy result is Cisco ISE assigning an authorization profile that might also involve a downloadable ACL specifying traffic management on the network policy enforcement device. The downloadable ACL specifies the RADIUS attributes that are returned during authentication and that define the user access privileges granted once authenticated by Cisco ISE.
An authorization profile acts as a container where a number of specific permissions allow access to a set of network services. The authorization profile is where you define a set of permissions to be granted for a network access request and can include:
• A profile name
• A profile description
• An associated DACL
• An associated VLAN
• An associated SGACL
• Any number of other dictionary-based attributes -
ISE Node Failure & Pre-Auth ACL
Hi All,
I would like to know that, what should be the best practice configuration for following points,
1) Network access for end users/devices if both ISE nodes become unreachable ? how we can make sure that full network access should be granted if both ISE nodes become unavailable.
2) What is the best practice for pre-auth ACL configuration if IP Phones are also in the network ?
Here is the port configuration and pre-auth ACL which I am using in my network,
Interface Fa0/1
switchport access vlan 30
switchport mode access
switchport voice vlan 40
ip access-group ISE-ACL-DEFAULT in
authentication event fail action authorize vlan 30
authentication event server dead action authorize vlan 30
authentication event server alive action reinitialize
authentication host-mode multi-domain
authentication open
authentication order dot1x mab
authentication priority dot1x mab
authentication port-control auto
authentication periodic
authentication timer reauthenticate server
authentication violation protect
mab
dot1x pae authenticator
dot1x timeout tx-period 5
ip access-list extended ISE-ACL-DEFAULT
remark DHCP
permit udp any eq bootpc any eq bootps
remark DNS and Domain Controllers
permit ip any host 172.22.35.11
permit ip any host 172.22.35.12
remark Ping

Thanks & Regards,
MujeebHi,
I am using following configuration on the ports,
Interface Fa0/1
switchport access vlan 30
switchport mode access
switchport voice vlan 40
ip access-group ISE-ACL-DEFAULT in
authentication event fail action authorize vlan 30 ----> What would be the behaviour due to this command ?
authentication event server dead action authorize vlan 30 ---> So in case if ISE nodes are unavailable then this port will be in VLAN 30 which is the actual VLAN ?
authentication event server alive action reinitialize ---> This command will re-initialize the authentication process if ISE nodes becomes available ?
authentication host-mode multi-domain
authentication open
authentication order dot1x mab
authentication priority dot1x mab
authentication port-control auto
authentication periodic
authentication timer reauthenticate server
authentication violation protect
mab
dot1x pae authenticator
dot1x timeout tx-period 5
Since I am using following ACL on the ports then user will have network access according to following ACL in case ISE nodes are unavailable ??
ip access-list extended ISE-ACL-DEFAULT
remark DHCP
permit udp any eq bootpc any eq bootps
remark DNS and Domain Controllers
permit ip any host 172.22.35.11
permit ip any host 172.22.35.12

I am currently migrating from CAS solution to ISE for posture assessment. Currently I am using LDAP for Authorization. When testing against ISE, I am unable to authorize users without changing the the Authorization setting to ISE on my ASA. Problem is we use LDAP to make sure the user is in the right group for access. We aren't using ISE in an Active Directory setting. Is there a way I can trigger ISE to do the Posture Assesment without having to change my current Authorization scheme to ISE?
You might be able to get it working using the AD server as the first authentication and ISE for the second one - sort of a 2-factor authentication model. As I understand it, you're really making a decision to authenticate with AD, not an authorization decision per se.
Why not integrate ISE with AD and use it for both group validation and posture assessment? That's a common deployment scenario. -
I am trying to create an authorization profile in ISE. My vlan for that profile is 50. When I try to add the Tag ID as 50 it is not allowing me to do so.
The message I am getting is : “Tag ID should contain only numerical value and in the range 0-31. How can the vlan be 0”. How to deal with this issue when my vlan ids are higher then 31.
I was wondering if anyone else had similar issue? Or am I missing anything.

Authentication order and ISE authorization policys
Hello
I'm looking at configuring ISE to authenticate AD joined PC's (using Anyconnect NAM for user and machine authentication with EAP chaining) and to profile Cisco IP phones. The Pc's and phones connect on the same switchport. The switchport configuration for this was:
switchport
switchport access vlan 102
switchport mode access
switchport voice vlan 101
authentication event fail action next-method
authentication host-mode multi-domain
authentication order dot1x mab
authentication priority dot1x mab
authentication port-control auto
mab
snmp trap mac-notification change added
snmp trap mac-notification change removed
dot1x pae authenticator
The above config worked fine with the "show authentication sessions" on the switch showing dot1x as the method for the DATA domain and mab for VOICE. I decided to reverse the authentication order/priority on the switch interface so that the phone would be authenticated first with mab. This resulted in the "show authentication sessions" on the switch showing mab as the method for both DATA and VOICE domains.
To prevent this I created an authorization policy on ISE to respond with an "Access-Reject" when the "UseCase = Host Lookup" and the Endpoint Identity Group was Unknown (the group containing the AD PC's). This worked fine - the switch would attempt to authenticate both PC and phone using mab. When an "Access-Reject" was received for the PC, the switch would move onto the next method and the PC would be successfully authenticated using dot1x.
The only problem with this is that the ISE logs soon become full with the denys caused by the authorisation policy - is there any way to acheive the above scenario without impacting on the logs?
Thanks
AndyHi Andy-
Have you tried to have the config in the following manner:
authentication order mab dot1x
authentication priority dot1x mab
This "order" will tell the switchport to always start with mab but the "priority" keyword will allow the switchport to accept dot1x authentications for dot1x capable devices.

ISE authorization Policy not working
Hi ,
I have configured the ISE as per the belwo link
https://supportforums.cisco.com/document/110031/central-web-authentication-cwa-guests-ise
but my authorization policy is not working as when user get connected to guest wlan it get authneticated but when it look for authorization
it going to default policy it should hit on above policy created screen shot as belowWhat version of ISE + patch are you running?. Could you please send an screenshot of AUTH policies including the default --- > USE part?. Are you using customized portal for the first authentication process?
CWA is pretty straightforward. Only issues I faced was multiple VM (ISE Personas) running on one single server was not replicating properly the AUTHZ policies so I added the PSN persona into the PAN Node and everything worked fine immediately. In addition to that, I realized that I needed at least ONE ENTRY into the ISE PAN Internal Endpoints DB so I could hit the AUTH Policy for MAB & user not found condition which sent me to the AUTHZ = User Unknown + Redirect. Once I authenticated the user using the Default Portal that meant I hit the GUEST FLOW policy. If you are using customized portals for the first authentication process, check: web portal mgmt. --- > Guest --- > MultiPortal Configurations --- > Customized Portal -- > Authentication part. -
IBNS with ISE, authorization issue
I'm running the 90-day ISE demo and trying to configure IBNS with it. I love the feel of the interface and almost instantly had a set of policies up and working fine. My issue is this:
I have an authorization service for machines so before a user logs in, their machine will authenticate to a list of machines in AD. This will give them guest/limited access.
I have a second authorization service for users. Once the user authenticates to AD, they should get access based on user group or other AD attributes. However once the user authenticates to AD, the previous authorization service that they had before is still enforced. The user is stuck with machine authorization. I figured that it was because the setting was "First Matched Rule Applies" so I switched to Multiple and now after the login, it still matches machine authorization but it now also matches on Default which will deny access...how can something match both authorized and default?
Because of that I have to make the machine authorization setting open to everything. Can anyone provide any guidance on this issue as config examples and such aren't out yet for ISE and the admin guide wasn't very helpful with this particular issue.
Thanks
XavierThe problem is that when the user is authorised after the machine is authorised, he still gets Machine Access (number 6). The user is supposed to get Engineer Access based on the IBNS User Authorisation Rule in number 1.
Comparing 5 and 6, the username for 5 is host/machineName/domain which should be granted Machine Access based on how AD is set up (with a list of hostnames of Domain Computers). In number 6 the username is domain/username which indicates it's a domain user and so he should get engineer access. For some reason, ISE doesn't want to match with the new authorisation rule and just keeps the one that I had before. -
Hi
I want to find out if its possible on ISE dot1x implementation to authenticate domain machines using EAP-TLS (certificate) and after successful authentication, authorize the user using AD domain users. I cant seem to get this to work, the ISE just skips the authorization policy which I created to reference AD.
It seems you can only authenticate and authorize with the same parameter which i was able to achieve using MSCHAP-V2.
My aim is to authenticate the connecting PC using internal CA and further authorize the users using AD membership.
ThanksAlthough EAP Fast and the EAP chaining are not proprietary to Cisco, AnyConnect is the only supplicant that I am aware of that currently supports the feature.
The only other option that I tell you is using machine access restrictions MAR, but I would highly recommend against this unless the customer is aware of the caveats associated with MAR. With MAR the supplicant is configured to use "user or computer" When the user is logged off the device authenticates using the computer's account. When the user logs in the supplicant starts the authentication process over using the user credentials. With MAR ISE first verifies that the machine authenticated before the user. If not then the user is not authorized to connect. The issue is that if the device goes into hibernation instead of logging off the user may fail to authenticate because ISE doesnt see the computer auth.
EAP chaining is the answer to MAR's shortfalls. This is because the computer and the user authenticate together everytime.
If their goal is to ensure that the device is a corporate owned device then you can always consider posture as a means to ensure that. You can have a registry entry, or file on the computer that signifies that the device is a corporate owned device. You would still need to install the posture agent and this would change the licensing requirements where as eap chaining is included in the base licensing and doesn't require plus or apex.
The other outside of the box idea that i have seen is to use GPO to change the LAN NIC's name
to something like "Corporate LAN" and then using profiling you can create a custom profile that matches. See pages 91-114 there are several options listed including the ones I've already mentioned.

Cisco ISE Authorization with Device OS
Hi,
We want to permit access only to devices with Windows OS. I tried to make a authorization rule with the condition "Session:Device-OS EQUALS Windows" but it doesn't work. If I try to connect with a Windows 7 client, the access is denied and the log shows "15039 Rejected per authorization profile". What could be the problem?
We are using ISE with Version 1.1.3
thank you,
