• Posture ISE 1.3 Inline node

  Hello

  who can explain the function of the posture inline node? What functionality are related to this type of node?

  That's right, assuming it's the flavor of Cisco's cost (which is partly based on pairs of RADIUS A - V that use Cisco Vendor-Specific Attributes or VSA).

  Third party n can support cost normalised (via RFC 3576 and 5176) and not necessarily work with ISE. Aerohive is an example I know.

• procedure to join unit ISE become node posture inline

  Hi all

  I ask, because I had 2 units of ISE-3315 device, we need to be the primary node of monitoring service admin-policy, another unit then become node posture Inline.

  For the preparation on the node line posture, what should you do about it?

  My question is:

  01 for the unit ready to become inline posture, so I simply start, install the OS of sractch (using version 1.1.1), then start the configuration to initialize etc, as the Normal Installer?

  02. until I regieter, which is the deplotment nodes should I choose to posture inline node unit?

  condition that the admin-service-management policy will become the primary node and node of posture inline registration will be the next action.

  Thank you

  Noel,.

  The scope of my comment was based on the deployment of the ISE, the VPN nodes and Ipep use RADIUS. The connection to the IPEP and vice versa ISE node admin will have adequate certs in place because they use ssl to authenticate and encrypt their data.

  Thank you

• Right way to restart the ISE PSN node in a distributed deployment

  Hi all

  Two of my ISE nodes (in a 1.2 8 node deployment) have expired admin CLI past (I know I'm stupid!)

  One is the secondary node MnT and one is a PSN node (1 of 4).

  I have some information on what I need to do to get a new password, but I have to unregister the nodes first or can I restart them.

  Will be my other three nodes PSN automatically re - authenticate users on PSN restart node or should I ask the downtime?

  Thanks for any help in advance

  Mark

  Right, shouldn't be a problem.  You certainly wouldn't want to remove it - you'd only if you need to reimage or something like that.

  Just as a tip, if you speak only use wireless cases, you could always disable this particular NHP since authentication Radius and Radius Accounting servers in the world (not over the WLAN).  If you make a change to the WLAN, it will "bounce" the WLAN.  But, if globally disable you "admin" that particular NHP, it will keep just the WLC as NHPS by up to that turn you it on again.

• ISE HA / node licenses group

  I have a single ISE 3355 with 2200 basic licenses.

  I intend to buy an another 3355 for redundancy purposes.

  Just add this in the node group and the license pool is shared between the nodes? I can't imagine that I have to rebuy all licenses for the 2nd device.

  Thanks in advance.

  That is right.  There is not need to purchase licenses additional paks.  ISE deployment licenses are based by endpoint, not by the node of the ISE.  You can simply add the new node to the existing deployment.

  You have probably already seen this, but here's a guide for distributed deployments:

• Purge of ISE MnT node running for 6 consecutive days

  Hi all

  Our ISE 1.1.4 patch 2 MnT node seems to be stuck in the purge of the DB. I get e-mail alerts that say "hourly purge jumped as purge has started execution." Also, when I try to run a backup of the node MnT I get the message. "Cannot submit the full backup when the purge of the data is ongoing."

  We received the error 'cursors open maximum exceeded. " When I arrived I have re-synchronized deployment who handed running the services on the node of NCDs. This cleared the error of open cursors but we left where we are now. I was hoping he would liberate itself over time, but it didn't.

  All I can think to do is to restart the services of EHT on the terrain node, but I'm a little worried about what could happen if I do this in the middle of a purge. Of course we do not have a recent backup of the terrain (see above), and I wouldn't want to lose historical data.

  I did not open a TAC again, if not answers here. We cannot patch or upgrade above 1.1.4 patch 2 because we're waiting on a fix for a bug unrelated.

  Any ideas appreciated, thank you.

  Hi Leroy Plock,

  Let me explain the root cause of the experience, the "hourly purge jumped as purge is already running."

  While the hourly purge process is triggered the Terrain node has experienced the problem of open cursors and so as there is no open thread / update a communication of the complete process from purge to purge logic, the hourly purge is hit in the running state.

  Her can be solved by changing the people who runs already serving the process to completed status. By cela the next hourly purge process will be triggered automatically.

  The alarm you see that purging process is already running is the side effect of the default of the said above CSCuh70984.

  Please open a SR with TAC and they help you to address the fix for the purge running alarms.

  The reason for seeking to prosecute TAC is that the difficulty is by running the database of SQL queries on your database of NTMS and once that is done, you must restart the services on the node MNT.

• ISE PSN node will not be joining the cluster

  Hi all

  Has anyone seen a problem where an NHP cannot join the cluster?

  We join node of PSN

  -Node is saved successfully (current synchronization)

  -1 hour later - node replication failure.

  -Replication synchronization failed because the secondary database is down

  I have a client where admin node and PSN are separated by the firewall.

  We let in two directions

  Admin <-->PSN

  ICMP

  HTTPS

  1521

  Firewall not showing drops.

  DNS and NTP are ok.

  Current topology is 1 NHP, 1 Admin node.

  Works very well in our test lab, but not clients environmnet.

  See you soon

  Peter.

  Thank you for the update we and good work on the search for the solution! You should probably mark it as resolved now

  In addition, it is quite rare (at least for me) for nodes of ISE to be separated by firewalls. There are a lot of ports/protocols that must be opened between them is usually more of a pain to manage. In addition, sometimes ports will change too. For example, the fueling port agent has been changed not too long ago...

  Thanks for the note!

• ISE web auth for other than cisco switch (D-link 3528)

  Is it possible to use ISE (posture inline node) to redirect to portal comments ISE wired users?

  And wired users will get full network access after they pass the web auth.

  Hello

  Theoretically, it could work if the switch is able to send all the attributes in accounting packets, such as IP address and mac address by asking the station id. If the attributes are missing or incorrect, the iPEP ISE will never create the session (see show pep session table).

  That said, who probably never have been tested, so you may want to reconsider your design, there is no guarantee that this can still work.

• 1.2 of the ISE and iPEP required certificates

  Hello

  For version 1.1.x of ISE, there are a few constraints on the certificates used for iPEP and Admin:

  Both EKU attributes must be disabled, if the two attributes, EKU are disabled in the certificate of Inline Posture, or the two attributes, EKU must be activated, if the server attribute is enabled in the certificate Postur Inline.

  • [http://www.cisco.com/en/US/products/ps11640/products_configuration_example09186a0080bea904.shtml]
  • The same applies for iPEP ISE 1.2? For ISE 1.2 User Guide and Setup Guide material does not mention anything about EKU and the attributes of specific certificate...
  • Any thoughts?
  • Thank you
  • Octavian

  Validation of EKU has been removed in version 1.2

  "If you configure ISE for services like Inline Policy Enforcement Point (iPEP), the model used to generate the ISE server identity certificate must contain attributes to authenticate client and server if you use ISE Version 1.1.x or earlier." This allows the admin and inline nodes to mutually authenticate each other. The validation of the EKU for iPEP was removed in ISE Version 1.2, which makes this less relevant requirement. »

• Cisco ISE

  Hi all

  I intend to implement cisco ISE in my network. I have 1000 endpoints and some mobile devices. I plan to use approach distributed and all licenses possible.

  It is: should I buy licenses for all nodes. For example 1000 for the head node, 1000 for high school, 1000 for surveillance and so forth?

  Or should I buy license only 1000 (I mean 1000 base + 1000 advances + 100 mobile) ones and apply them to all nodes?

  Concerning

  Max

  Hi Max.

  ISE is authorized by the deployment. So if you have a distributed with us deployment will tell ISE 10 nodes or servers you will always only the node main Administrator license.

  Now, if you plan to have two deployments (say a deployment for the EMEA region and the other for APAC) then you would need licenses for both deployments (you allow the node primary admin in each deployment).

  I hope this makes sense :)

• ISE 1.3 psn redundancy

  Hello

  in my environment, I have a lot of remote site with an NHP, may be possible create redundant end a group of psn with primary and secondary node and the psn remotely? My problem... the node are in the other subnet.

  There are several options for redundancy PSN.

  You can use a load balancer (with or without a group node), or just multiple PSN with different NADs pointing towards one or the other as the first in the list of least favorite listed as secondary, tertiary, etc.

  From 1.3 ISE, the node group members no longer have to be in the same subnet (or TTL = 2 accessibility) but it's always a recommendation whether they are within the same network of high speed for replication.

  So for your scenario, this last method is probably indicated. Take a look at the Cisco Live BRKSEC-3699 presentation, and then search for "n RADIUS Server redundancy-based" for more details.

• Upgrading ISE to the deployment of node 2.0 - two

  Hello!

  As we know that the ISE 1.3 can be upgraded to ISE 2.0 in two different ways. One is to use the upgrade of the Application that is fully automatic and the other way is the new facility of ISE 2.0 (full to the top of the nodes of ISE before installation).

  Tutorials I've seen so far, described primarily on Application upgrade method, but I would like to know about the new facility of ISE 2.0. I choose this option, because it gives us more granular control of the upgrade.

  If anyone have tried this second method for the ISE2.0 upgrade, please share your experience, and give us the procedure step by step. Thank you in advance.

  Bala

  Hello Bala-

  You can do one or the other. Personally, I prefer the direct upgrade path as the back/restore doesn't cary all settings and configurations. In addition, you will need to get new license keys as the ISE system will be new/different, so your old license keys will not work.

  I hope this helps!

• ISE 1.1 error displaying the home page when looking on the secondary node

  Hello

  I made an ISE installation with a primary and a secondary node - basically, it works very well.

  My problem is when looking on the secondary node e I get a certificate error which pointing to this page looking for the browser gets information from the primary node that makes the browser do not to display info. On the primary, it works fine.

  First I used self-sign certificates, subsequently I installed certificates frm the local certification authority - the problem remained the same.

  I tried with IE, Firefox and Chrome.

  When you change the primary/secondary role, the problem always moved to the real secondary node.

  Anyone an idea what to do here?

  Andreas

  If you use self CERT signed, you must connect to the node seconeary, once you trust cert, you'll be able to see everything on the head node.

  Thank you

• ISE-impossible to register a node

  Hi all

  We strive to integrate a new node ISE as a PSN for our current configuration. When we try to register, we get below error messages. -What someone faced same question. Also need clarity on these error messages.

  When you try to record with the IP address that we get the error message as below:

  Cannot authenticate ISE secondary_ise_name. Please check the server and the configuration of the CA certificate and try again.

  When you try to record with the domain name FULL we get the error message as below:

  FULL "XYZ.local.com", which is not resolved domain name. Please check your DNS configuration.

  If need to clarity if it is a DNS issue or certificate.

  Kind regards

  Avinash

  Hello

  Please ensure that your FULL domain name can be resolved by your ISE.

  For this you must add the entry for your server's DNS.
