Hi Antonio,
Many great questions to start this series. For the situation that you are observing with your FlexConnect configuration, is the problem 100% reproducible or is it intermittent? Does the problem happen for one WLAN but not another? As it stands today, the CoA-Ack needs to be initiated by the management interface. This limitation is documented in bug CSCuj42870. I have provided a link for your reference below. If the problem happens 100% of the time, the two configuration areas that I would check first include:
On the WLC, navigate to Security > RADIUS > Authentication. Click on the server index number for the associated ISE node. On the edit screen, verify that the Support for RFC 3576 option is enabled.
On the WLC, navigate to the WLANs tab and click on the WLAN ID for the WLAN in question. On the edit screen, navigate to Security > AAA and make sure the Radius Server Overwrite interface is unchecked. When this option is checked, the WLC will attemp to send client authentication requests and the CoA-Ack/Nak via the dynamic interface assigned to the WLAN vs. the management interface. Because of the below referenced bug, all RADIUS packets except the CoA-Ack/Nak will actually be transmitted via the dynamic interface. As a general rule of thumb, if using the Radius NAC option on a WLAN, you should not configure the Radius Server Overwrite interface feature.
Bug Info: https://tools.cisco.com/bugsearch/bug/CSCuj42870
For your second question, you raise a very valid point which I am going to turn into a documentation enhancement request. We don't currently have a document that lists the possible supplicant provisioning wizard errors that may be encountered. Please feel free to post specific errors that you have questions about in this chat and we will try to get you answers. For most Android devices, the wizard log file can be found at /sdcards/downloads/spw.log.
As for product roadmap questions, we won't be able to discuss this here due to NDA. Both are popular asks from the field so it will be interesting to see what the product marketing team comes up with for the next iterration of ISE.

Ask the Expert: Identity Services Engine - 802.1x, Identity Management and BYOD

Welcome to this Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about Cisco Identity Service Engine (ISE) with subject matter expert Nicolas Darchis.
Cisco Identity Service Engine is a security policy management and control platform that automates and simplifies access control and security compliance for wired, wireless, and VPN connectivity. It is primarily used to provide secure access and guest access, support BYOD initiatives, and enforce usage policies in conjunction with Cisco TrustSec.
Nicolas Darchis is a wireless and authentication, authorization, and accounting expert for the Technical Assistance Center at Cisco Europe. He has been troubleshooting wireless networks, wireless management tools, and security products, including Cisco Secure Access Control Server, since 2007. He also focuses on filing technical and documentation bugs.

Hi.
1) It is not "ISE loses the credentials and asks for web portal again". Once a user is authenticated, it is authenticated as long as it stays connected. Possibilities are :
-You are returning a session timeout (attribute radius 27) in the authz profile of the user. Therefore user has to reauthenticate after X seconds. But you would see a pattern, then.
-Over wireless, many clients are not capable of doing fast roaming (smartphones is the biggest example) and will therefore reauthenticate with dot1x everytime they roam. A small coverage hole would be enough for the cached credentials to disappear and web portal to show up again
-Over wired, this cannot really occur but the idea is that it's probably the switch resetting the connection and contacting ISE again. The idea to troubleshoot this is to monitor the access device (WLC/switch) and check if the port goes up/down, if the MAB session gets reset or something and why.
2) The captive bypass issue is that Apple devices will probe apple.com website to check if there is internet connectivity. If they can reach it, then fine, if they sense that they are redirected, they open a small window pop up with the login portal. The problem (and I still cannot understand why) is that this is not Safari, it's some nameless feature-less browser that doesn't work properly.
By enabling the captive bypass feature, the WLC intercepts the requests to the Apple testpage and replies with HTTP OK. The apple device then thinks "ok I have internet connectivity" and it's up to the user to bring up a real browser to login to the portal page.
It therefore does not affect non-Apple device to have the feature enabled.
The problem is that in IOS 7.x, Apple decided to not just use Apple.com anymore but a whole list of testpages on different websites.
3) "whether it would solve the issue if I added certificate authentication as a secondary option, with eap-tls as the primary"
=> This is disturbing because EAP-TLS is a certificate authentication method. But ISE message seems to imply that the user is hitting an authnetication rule that only provides PEAP or EAP-FAST with mschap or something similar ...
If you have the windows default supplicant you have close to no control on what the client will submit. I can imagine that moving from wired to wireless, the laptop would sometimes try to send password instead of certificate and/or vice-versa. Anyconnect with fixed network profiles would solve the problem elegantly.
I cannot comment on your auth policies as I do not know them :-)
Regards,
Nicolas

OOPS !!
I will repost the whole messaqge with the correct external URL's:
In general, the Trustsec design and deployment guides address the specific support for the various features of the 'whole' Cisco TS (and other security) solution frameworks. And then a drill-down (usually the proper links are embedded) to the specifc feature, and then that feature on a given device. TS 2.1 defines the use of ISE or ACS5 as the policy server, and confiugration examples for the platforms will include and refer to them.
TrustSec Home Page

I find this page very helpful as a top-level start to what features and capabilities exist per device:

1. Without more specifics it is hard to determine actual issue. It may be possible that if configured in same subnet that asymmetric traffic caused connections to fail. A key enhancement in ISE 1.3 is to make sure traffic received on a given interface is sent out same interface.
2. Common use cases for using different interfaces include separation of management traffic from user traffic such as web portal access or to support dedicated profiling interfaces. For example, you may want employees to use a different interface for sponsor portal access. For profiling, you may want to use a specific interface for HTTP SPAN traffic or possibly configure IP Anycast to simplify reception and redundancy of DHCP IP Helper traffic. Another use case is simple NIC redundancy.
a. Management traffic is restricted to eth0, but standalone node will also have PSN persona so above use cases can apply for interfaces eth1-eth3.
b. For dedicated PAN / MnT nodes it usually does not make sense to configure multiple interfaces although ISE 1.3 does add support for SNMP on multiple interfaces if needed to separate out. It may also be possible to support NIC redundancy but I need to do some more testing to verify.
For PSNs, NIC redundancy for RADIUS as well as the other use cases for separate profiling and portal services apply.
Regarding Supplicant Provisioning issue, the flows are the same whether wireless or wired. The same identity stores are supported as well. The key difference is that wireless users are directed to a specific auth method based on WLAN configuration and Cisco wired switches allow multiple auth methods to be supported on same port.
If RADIUS Proxy is required to forward requests to a foreign RADIUS server, then decision must be made based on basic RADIUS attributes or things like NDG. ISE does not terminate the authentication requests and that is handled by foreign server. ISE does support advanced relay functions such as attribute manipulation, but recommend review with requirements with local Cisco or partner security SE if trying to implement provisioning for users authenticated via proxy. Proxy is handled at Authentication Policy level. CWA and Guest Flow is handled in Authorization Policy. If need to authenticate a CWA user via external RADIUS, then need to use RADIUS Token Server, not RADIUS Proxy.
A typical flow for a wired user without 802.1X configured would be to hit default policy for CWA. Based on successful CWA auth, CoA is triggered and user can then match a policy rule based on guest flow and CWA user identity (AD or non-AD) and returned an authorization for NSP.
Regarding AD multi-domain support...
Under ISE 1.2, if need to authenticate users across different forests or domains, then mutual trusts must exist, or you can use multiple LDAP server definitions if the EAP protocol supports LDAP. RADIUS Proxy is another option to have some users authenticated to different AD domains via foreign RADIUS server.
Under ISE 1.3, we have completely re-architected our AD connector and support multiple AD Forests and Domains with or without mutual trusts.
When you mention the use of RADIUS proxy, it is not clear whether you are referring to ISE as the proxy or another RADIUS server proxying to ISE. If you had multiple ISE deployments, then a separate RADIUS Server like ACS could proxy requests to different ISE 1.2 deployments, each with their own separate AD domain connection. If ISE is the proxy, then you could have some requests being authenticated against locally joined AD domain while others are sent to a foreign RADIUS server which may have one or more AD domain connections.
In summary, if the key requirement is ability to join multiple AD domains without mutual trust, then very likely ISE 1.3 is the solution. Your configuration seems to be a bit involved and I do not want to provide design guidance on a paper napkin, so recommend consult with local ATP Security SE to review overall requirements, topology, AD structure, and RADIUS servers that require integration.

Craig

Ask the Expert: Scaling Data Center Networks with Cisco FabricPath

With Hatim Badr and Iqbal Syed
Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about the Cisco FabricPath with Cisco technical support experts Hatim Badr and Iqbal Syed. Cisco FabricPath is a Cisco NX-OS Software innovation combining the plug-and-play simplicity of Ethernet with the reliability and scalability of Layer 3 routing. Cisco FabricPath uses many of the best characteristics of traditional Layer 2 and Layer 3 technologies, combining them into a new control-plane and data-plane implementation that combines the immediately operational "plug-and-play" deployment model of a bridged spanning-tree environment with the stability, re-convergence characteristics, and ability to use multiple parallel paths typical of a Layer 3 routed environment. The result is a scalable, flexible, and highly available Ethernet fabric suitable for even the most demanding data center environments. Using FabricPath, you can build highly scalable Layer 2 multipath networks without the Spanning Tree Protocol. Such networks are particularly suitable for large virtualization deployments, private clouds, and high-performance computing (HPC) environments.
This event will focus on technical support questions related to the benefits of Cisco FabricPath over STP or VPC based architectures, design options with FabricPath, migration to FabricPath from STP/VPC based networks and FabricPath design and implementation best practices.
Hatim Badr is a Solutions Architect for Cisco Advanced Services in Toronto, where he supports Cisco customers across Canada as a specialist in Data Center architecture, design, and optimization projects.

Hi Sarah,
Thank you for your question.
Spanning Tree Protocol is used to build a loop-free topology. Although Spanning Tree Protocol serves a critical function in these Layer 2 networks, it is also frequently the cause of a variety of problems, both operational and architectural.
One important aspect of Spanning Tree Protocol behavior is its inability to use parallel forwarding paths. Spanning Tree Protocol forms a forwarding tree, rooted at a single device, along which all data-plane traffic must flow. The addition of parallel paths serves as a redundancy mechanism, but adding more than one such path has little benefit because Spanning Tree Protocol blocks any additional paths
In addition, rooting the forwarding path at a single device results in suboptimal forwarding paths, as shown below, Although a direct connection may exist, it cannot be used because only one active forwarding path is allowed.
Virtual PortChannel (vPC) technology partially mitigates the limitations of Spanning Tree Protocol. vPC allows a single Ethernet device to connect simultaneously to two discrete Cisco Nexus switches while treating these parallel connections as a single logical PortChannel interface. The result is active-active forwarding paths and the removal of Spanning Tree Protocol blocked links, delivering an effective way to use two parallel paths in the typical Layer 2 topologies used with Spanning Tree Protocol.
vPC provides several benefits over a standard Spanning Tree Protocol such as elimination of blocker ports and both vPC switches can behave as active default gateway for first-hop redundancy protocols such as Hot Standby Router Protocol (HSRP): that is, traffic can be routed by either vPC peer switch.
At the same time, however, many of the overall design constraints of a Spanning Tree Protocol network remain even when you deploy vPC such as
1.     Although vPC provides active-active forwarding, only two active parallel paths are possible.
2.     vPC offers no means by which VLANs can be extended, a critical limitation of traditional Spanning Tree Protocol designs.
With Cisco FabricPath, you can create a flexible Ethernet fabric that eliminates many of the constraints of Spanning Tree Protocol. At the control plane, Cisco FabricPath uses a Shortest-Path First (SPF) routing protocol to determine reachability and selects the best path or paths to any given destination in the Cisco FabricPath domain. In addition, the Cisco FabricPath data plane introduces capabilities that help ensure that the network remains stable, and it provides scalable, hardware-based learning and forwarding capabilities not bound by software or CPU capacity.
Benefits of deploying an Ethernet fabric based on Cisco FabricPath include:
• Simplicity, reducing operating expenses
– Cisco FabricPath is extremely simple to configure. In fact, the only necessary configuration consists of distinguishing the core ports, which link the switches, from the edge ports, where end devices are attached. There is no need to tune any parameter to get an optimal configuration, and switch addresses are assigned automatically.
– A single control protocol is used for unicast forwarding, multicast forwarding, and VLAN pruning. The Cisco FabricPath solution requires less combined configuration than an equivalent Spanning Tree Protocol-based network, further reducing the overall management cost.
– A device that does not support Cisco FabricPath can be attached redundantly to two separate Cisco FabricPath bridges with enhanced virtual PortChannel (vPC+) technology, providing an easy migration path. Just like vPC, vPC+ relies on PortChannel technology to provide multipathing and redundancy without resorting to Spanning Tree Protocol.
Scalability based on proven technology
– Cisco FabricPath uses a control protocol built on top of the powerful Intermediate System-to-Intermediate System (IS-IS) routing protocol, an industry standard that provides fast convergence and that has been proven to scale up to the largest service provider environments. Nevertheless, no specific knowledge of IS-IS is required in order to operate a Cisco FabricPath network.
– Loop prevention and mitigation is available in the data plane, helping ensure safe forwarding that cannot be matched by any transparent bridging technology. The Cisco FabricPath frames include a time-to-live (TTL) field similar to the one used in IP, and a Reverse Path Forwarding (RPF) check is also applied.
• Efficiency and high performance
– Because equal-cost multipath (ECMP) can be used the data plane, the network can use all the links available between any two devices. The first-generation hardware supporting Cisco FabricPath can perform 16-way ECMP, which, when combined with 16-port 10-Gbps port channels, represents a potential bandwidth of 2.56 terabits per second (Tbps) between switches.
– Frames are forwarded along the shortest path to their destination, reducing the latency of the exchanges between end stations compared to a spanning tree-based solution.
    – MAC addresses are learned selectively at the edge, allowing to scale the network beyond the limits of the MAC addr

Hello Jason,
Thank you very much for welcoming me to your expert discussion :) I feel to be in the right place, at the right time. Thank you also for answering question beyond your scope here, much appreciated. The information received will help me to go further as such I have submitted a 5 start rating for your first reply.
That sounds promising about the LMS part so yes, I stay tuned and wait patiently.
Ok, now let’s revert to the actual topic discussed here. Cisco Prime Service Catalog and Process Orchestrator solutions I have briefly read up on this on CCO (where elseJ) and picked out the following quote
---- Quote from the Cisco Prime Service Catalog Data Sheet
Today’s end users want self-service and easy access to IT tools and services.
Simultaneously, organizations are seeking ways to extend their cloud management
platforms beyond self-service delivery of virtual machines and infrastructure resources
while increasing their use of cloud-based solutions to enhance business agility and effectiveness.
Cisco Prime™ Service Catalog offers tremendous benefits to organizations that want to unify the ways in
which all types of IT services are ordered and fulfilled, not just infrastructure requests
---- un quote ---
I try to understand what (at high level of course) happens in the back ground when an order is raised and which vendor solution your product can interact with.
As mentioned in the quoted text, this service catalogue goes beyond the standard infrastructure.
Let’s say, a user wants to deploy a new email services, or in your example, extends or create a new web-portal (i.e. for HR to view and manage holiday, staff absence and benefits).
Your solution will need to interact somehow with the 3rd party vendor application that is capable building such portal I believe.
Without disclosing to many information, I assume the portal is linked to backend VM,s that spin up requested resources (and more magic of course). Perhaps I am mixing this up with another cisco product where a user can go on the portal and spin up virtual Firewalls, virtual Routers can be provisioned in now time.
Out if interest; Is this product also known as Mozart? (project code within Cisco?)
I hope query is ok.
Best wishes
Markus

FAQ

Is there a Cisco lab available for ASR 9000
we have "XR4U" stations coming available soon when XR 511 comes alive. The plan is for a downloadable play image like that. In the interim we have 2 demo systems available, and they can be booked via your account manager representative.
How will MOD160 perform with multiple 9000NVS?
very well. the mod 160 has 4 NPU's, 2 per bay. So if you have a 4x10 MPA to serve a satellite, you effectively have a single NPU per 20 1Gigs from the satellite. The pps performance will be stellar. However it might be price technically more ideal to connect satellite with a 36x10. Since the MOD-x has native MPA's with 1G also.
2. Is there a shortcut for a Bundle-EthernetX interface, such as port-channel interface (poX), in Cisco IOS® ?.
usability enhancement is there, we are trying to push this into a new reasonable release. follow CSCuh04526
3. What is the revolutions per minute (RPM) on these hard disk drives (HDDs) compared to the solid state drives (SDDs)? Will the spinning drives be slow?
depends on the type we had avaialble at time of production, you will see different sizes and disks on the RSP2. the rpm of the HD is not so much an issue as much as the buffered writing we used to do in XR. This is fixed up with XR43 where the disk writing performance is much better. the HD/SDD is used for logging storage only (and maybe your pictures) but other then that we're not that concerned with write perf of the HD.

Ask the Experts: Single Sign-On with Cisco WebEx Meetings Server, Internet Reverse Proxy, and Enterprise License Manager Solutions

With Arun Kumar
Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about Single Sign-On (SSO) with Cisco WebEx Meetings Server (Cisco WMS), Internet Reverse Proxy (IRP), and Enterprise License Manager (ELM) solutions.
SSO standards such as Security Assertion Markup Language (SAML) 2.0 provide secure mechanisms for passing credentials and related information between different websites that have their own authorization and authentication systems. SSO enables simplified user authentication and management.
IRP provides public access, enabling users to host or attend meetings from the Internet and mobile devices. Although IRP is optional, Cisco encourages its use because it provides a better user experience for your mobile workforce.
Example question topics include:
SSO profiles and SAML 2.0 Identity providers (IdPs) supported in Cisco WMS
Basic configuration of IdPs
Interaction between IdPs and Cisco WMS
Difference between the cloud client implementation and Cisco WMS
