• NAC L2 OOB VG Design for wired

  Hi all

  I need help of the NAC 2 OOB virtual layer for wired users design bridge . On Cisco documentation configuration only example is present, but it is for wireless users who is not applicable to my case (wired users); Here are the details; Please correct me if the design does not at any time;

  1: create a virtual local network (241) for the management of the CAM on the kernel.

  2: create a virtual local area network (240) for the management of CASES on the kernel.

  3: the IP addresses of both (10.10.240.1) E0 and E1 (10.10.240.1) for the CASE will be on the same subnet and same ip address.

  4: create all Trusted SVI's VLAN (vlan 10,20) on the kernel.

  5: configure manage subnets for vlan not reliable (100, 200) on CASES

  6: create a vlan mapping n/b approved and not approved (10 to 100, from 20 to 200)

  7: core connected to the CAs: E0, trunk allowed vlan 10, 20, 240

  8: core connected to the CAs: E1, trunk allowed vlan 100, 200

  9: another typical configuration

  I don't have a LABORATORY to test. I'm just confused if I missed something as implementation will be critical, and I'll try to avoid all risks.

  Please give me suggestion and best practices. Also please let me know if I need a config added?

  Kind regards

  Abdul,

  Port profiles are used to determine if a port is managed or not managed, so you will need at least a port profile. Here you can define what will be the VLAN initial of the switchports that the final VLAN will be etc etc.

• Problem of the NAC - Agent is a disconnect

  Hello

  We have a problem with the NAC in mode virtual outofband.

  AD SSO, sanitation, everything is working, but the strange things happening: after awhile, when downloading large files, Agent connects to the formula of network users, and the registration process is restarted.

  I disabled the pulsation clocks and timers, session, but we still have a problem.

  Also, while sniffing traffic on the switch port, I noticed that after have correctly connected you to the own Cisco Agent network always send traffic to UDP Port 8905. Is this a normal behavior?

  I noticed problems with this version of the agent causing connections to give up intermittently. I would upgrade to agent v4.1.3.1.

• Configuration of the switch of the NAC

  Hello!!

  I bought a NAC server and a manager of the NAC, to centrally manage the vlan where users connect to based on authentication.

  I have several sites, but the NAC server will be at Headquarters.

  When a remote user authenticates, NAC must configure the user switch port for the vlan right.

  What is an out-of-band solution?

  Do need me a specific license for out-of-band?

  Best of look,

  Miguel Amaral

  Hello

  It's the same pattern: Yo uneed 2 licenses, one for the CAM and the other for CAs.

  One cam sets the number of cases you can add.

  That case defines how many users is supported.

  So either the CASE PAK has been lost, or never bought.

  In both cases, you will need to contact the entitiy that sold devices and demand for the PAK CASE.

• Ports of the NAC

  Hello Experts,

  Have some questions that came across while doing work of the NAC at one of our subsidiaries. If there is some user ports which are not selected for the profile of the NAC, is it possible (except physical control on the cell phone of the user by allowing all ports & audit) which can be used to track the paths of users without mail for NAC.

  Second, if the user of the NAC port is manually on the vlan user (rather than quarantine or vlan temporary), which is the correct order for that.

  the user on NAC field must be typed manually to vlan user or port profile should try not controlled followed by rebound port & update.

  Apprecite all help, thank you.

  Hello

  See online:

  If there is some user ports which are not selected for the profile of the NAC, is it possible (except physical control on the cell phone of the user by allowing all ports & audit) which can be used to track the paths of users without mail for NAC.

  [Tiago] On the graphical interface of CAM, you can check which controlled uncontrolled ports are. It is the only place where ports can be determined to be managed/no managed.

  Second, if the user of the NAC port is manually on the vlan user (rather than quarantine or vlan temporary), which is the correct order for that.

  the user on NAC field must be typed manually to vlan user or port profile should try not controlled followed by rebound port & update.

  [Tiago] When you perform the configuration of the switch, the switchports can be put on the vlan user or default access vlan. It depends on the port profile settings that you have configured. By default, when a port is managed on the basis, if a client connects, an SNMP trap is sent to the CAM. The CAM check whether the machine is certified or not (check the mac address). If the machine is not certified cam becomes the vlan the authenticated vlan configured on the port profile.

  So, whenever you connect a PC to a switchport, CAM evaluates what is the vlan correct the PC to start and change it accordingly.

• Support of the NAC Profiler address & ip

  Hello

  I have a layer 3 OOB NAC Profiler deployment and I am trying Profiler some IP phones from a remote location by using the statement of helper-ip address on the interface on the remote router. The problem is that the remote router acts as a dhcp server for the vlan voice and fact not forword DHCP discover for Colectionneurs of the NAC, and I can't phone ip profile. Do you know a way (an order of configuration on the router) to forword the dhcp even though the router acts as a DHCP server for this vlan?

  Thank you

  Victor

  Hi Victor,

  To do this... You must add a SVI for the voice VLAN on the switch behind the router, and then add the IP helper on the new interface VLAN voice.

• Actual gateway IP process to strip the NAC

  Hi all

  I did a lot of research, and I can not find good answers to some of my questions. All the big questions are answered for out-of-band configuration, but I find that it is assumed that this understanding in the Strip is taken for granted lol... I guess I'm slow = P

  1. How does the gateway IP In-band real?
  2. What is the point of the 30 subnets?
  3. Are there any access/auth pairs VLAN configurations in the band?
  4. How does quarantine work?
  5. I read that the NAC server cannot send traffic on untrusted port to a VIRTUAL LAN and that you are not allowed to trunk port. This means that there is no support for several VLAN reliable, mapped to a single server at the NAC?
  6. Can you do role with configurations mapping in the band?

  Assistance for all or part of these questions would be GREATLY appreciated!

  Thank you a lot =]

  ~ Xavier.

  Hi Xavier,.

  I'll try to answer your questions

  1. How does the Strip Real-IP Gateway?

  The CASE works in routed mode, if you have different IP addresses (on different subnets) on interfaces approved and unapproved. Because the CASE does not support routing protocols, routing must be configured through static routes

  2. What is the point of the 30 subnets?

  The idea is to have small subnets for your customers so that with this config IP customers in authentication VLAN should through the CASE even to talk to other clients on the same subnet L2.

  Click here for an explanation:

  http://www.Cisco.com/en/us/docs/security/NAC/appliance/configuration_guide/47/CAs/s_dhcp.html#wp1057889

  3 is there access/auth pairs VLAN configurations in the band?

  If you ask if there is mapping VLAN, then the answer is NO, as the purpose of the VLAN mapping must * bridge * traffic between approved and unapproved mapped VLAN, but in real-IP the L3 routing traffic CASES.

  4. How does quarantine work?

  When a client is quarantined, it works the same way as OOB, as in this phase, the client is always online to the CAs.

  So the concept is assigned to the CASE by the temporary user or the role of midlife and he applies a traffic policy you've set up temporary or the role of midlife.

  5. I have read that the NAC server cannot send traffic on untrusted port to a VIRTUAL LAN and that you are not allowed to trunk port. This means that there is no support for several VLAN reliable, mapped to a single server at the NAC?

  The restriction of VLAN "single" for Real - IP CASE applies only to the * trust * side. The CASE may be the default gateway for several subnets VLAN / IP on the * rogue * side.

  Configuring addresses VLAN / additional IP on the unreliable side by using the configuration "managed subnet.

  This is mentioned here:

  http://www.Cisco.com/en/us/docs/security/NAC/appliance/configuration_guide/45/CAs/s_deploy.html#wp1050938

  The clean access server can manage one or more subnets, with its untrusted interface, acting as a gateway for managed subnets. For more information on the setup of managed subnets, see Configuring managed subnets or static routes page 5-26.

  6. can you do role with configurations mapping in the band?

  Yes, you can do it! However, you cannot assign a VLAN as you do in OOB, but you can assign the different level of access based on IP traffic strategies and bandwidth restrictions that you assign the specific role.

  For example, check here for more details:

  http://www.Cisco.com/en/us/docs/security/NAC/appliance/configuration_guide/45/cam/m_users.html#wp1040231

  In a Word, regardless of the use of the band vs OutOfBand:

  -customers are InBand before CAs in CASE detection, authentication, the phases of assessment and remediation of posture.

  The main difference occurs when the user is allowed to access the network and that you run the IB role assignment and OOB but... :

  -in customer traffic keeps on inline flowing to the IB CAs, so you can apply different access policies (ACL) and control of bandwidth depending on the role policies (but you cannot assign a VLAN);

  -in OOB, customer traffic bypasses the CASE once it is authorized: in this case, you can apply different VLAN but (given that the CASE is no longer along the way) you cannot apply ACL and/or ensuring the policy in this case.

  I hope that answers your questions.

  Kind regards

• Cam of the NAC could not add the access switch

  Hi all

  My problem is I can't add the access switch to the cam using mozilla firefox or IE.here attech file cannot add the device. Any idea to solve my problem?

  Hello

  Plese note to add a device (switch) to the CAm, you must go to the leadership of OOB-> appliances-> New.

  First, you must configure the SNMP settings on the switch and the cam so that the cam and the switch can communicate.

  I advise you to make sure that carefully read the configuration for OOB guide and management switch:

  http://www.cisco.com/en/US/docs/security/nac/appliance/configuration_guide/48/cam/m_oob.html.

• Integration of the NAC Profiler - cannot add list of filters on cam

  Hi all

  I have a problem with the Profiler - integration of the NAC for endpoint profiling.

  Here's the situation:

  I have already created the integration based on the steps in the Guide: Setup Cisco NAC Appliance integration. I think that the configuration is correct, because I can do database synchronization between the Profiler and CAM. Here's the log of server profile:

  NAC_SYNC: Task_Queue_Runner commissioning
  NAC_SYNC: Profiler / END of synchronization of the NAC [add 0, upd 0, desc 0, rm 0]
  NAC_SYNC: Profiler / START the synchronization of the NAC
  INFO: [2010-12-15 11:01:09 (fcapGetHWAddr:49)] is for eth0 MAC

  I have already created a profile of endpoint named "Admin" which is based on the IP address. I also created the NAC events based on endpoint profile 'Admin '.

  The event of the NAC will present 'Admin' profile to a role of the NAC. This event aims to circumvent 'Admin' of the legalisation of the ANC visa so that the "Admin" can connect to the network automatically to a role of the NAC.

  However, when 'Admin' to connect to the network, it still is challanged by NAC. I don't see "Admin" on the filter of the CAM or the list.

  This means that the endpoint profiling is still broken.

  Is there anyone who have experience with this?

  Thanks for the support and comments

  Imad

  Hello

  You cannot add devices manually on the profiler.

  The Profiler has to detect automatically (it is the concept of profiling).

  How this Profiler detects endpoints use the modules of collector.

  Each module has endpoints detection means.

  You will find the description of each collector module here:

• In the NAC MAC address filter list

  How are Faisal Hi, you? I have a question about this list of filters in the unit of the NAC. I want to do those recognized unit of the NAC mac addresses are to be get the network. However if a workstation's mac address is not in the filter list, would it not able to do the network. Is that the NAC has the ability to do? Please let me know. Thank you.

  Richard

  I'm not Faisal, but...

  You want to make additional (such as LDAP or such) or any authentication simply based on the MAC address?  If you want to only via the MAC, you can add them to the list of filters and then either set to 'allow' to allow all traffic, 'role' to put them in a specific role, or "check" to apply the evaluation of posture and then put them in the role.  If no other server authentication is configured, users who were not in the list of filters would not be able to authenticate, and they would be stuck in the authenticated VLAN.

  Thank you

• Profiler in the NAC 2.1 to 3.1 upgrade

  Hi guys,.

  I'm setting up a Profiler from the NAC that accompanies 2.1 installed. I upgraded to 3.1, prayed and installed the license without any problems, but I always get this message: "ERROR: [2010-12-08 09:25:01 (main: 668)] valid no key not found [no such file or directory]" "

  The license file exists, and on the interface Web Profiler from the NAC, the State of the license is OK.

  A single line in the license file gives me this information: 'cisco 2.1 INCREMENT CCA-MANAGER countless Permanent '.

  Does anyone know if the license is linked with the version of Profiler?

  The upgrade from 2.1 to 3.1 is allowed or it is necessary to purchase a new license 3.1?

  Best regards

  Hello

  So I guess you spotted the problem here...

  You have a collector's license?

  You need 2 licenses: 1 to the server profile, and one for the collector.

  Basically, the mac address you provide is the same (eth0 ot Server Profiler), but you need a PAK Server Profiler to generate the license Server Profiler (the one you already have) and a PAK for license collector (which is missing).

  You have the collector PAK?

  If Yes, then just go to the license page and submit this PAK and the mac address.

• Re-evaluation of the NAC 4.8 Passive does not work

  Hello

  After an upgrade to 4.8.0, we would like to use the passive re-evaluation function with L2 OOB.

  Everything is configured properly according to the Cisco NAC docs (enable OOB Logoff, user roles-> activate Passive reassessment).

  However, the sign-out OOB feature works well, for example. What a victory of logoff user, the user disconnects NAC.

  In the first times that the PrA works well, the CAM poster report revaluation records failed with red flags, but now it shows nothing that associated PRA.

  (I know, the poster reports only PrA records failed.).

  Try to reload all the elements of the CAM CASE HA, HA, but nothing has changed.

  Any suggestion?

  Thank you very much

  Attila

  Hi Attila,

  The debugs Agent, I see that the Agent reports the failure for the following conditions:

  % NACAGENT-6-REQUIREMENT_PROC: % [sev = info] [func = Rqmt::completeCheck]: check the result of rqmt [MS: hianyzo Windows frissites Windows XP (BKV)]:FAILED

  That't the only requirement that fails and it is also reported on the "NACAgentReport.xml" file that is part of the package you uplaoded and it has not been quantified.

  I think the problem is actually with the following parameter "default PrA on failure action - continue '.

  Please, set it to "allow the user to fix" or "Logoff user immediately" and check if the behavior is different.

  If this does not help, please open a TAC service request in order to study it.

  Thank you

• Logic and rules of the NAC

  I have a question about WINXP rules in the NAC server and more specifically, if a rule reports a failure, but it's part of a! the rule, this means - happening?  For example:

  / * Style definitions * / table. MsoNormalTable {mso-style-name : « Table Normal » ; mso-tstyle-rowband-taille : 0 ; mso-tstyle-colband-taille : 0 ; mso-style-noshow:yes ; mso-style-priorité : 99 ; mso-style-parent : » « ;" mso-rembourrage-alt : 0 à 5.4pt 0 à 5.4pt ; mso-para-marge-top : 0 ; mso-para-marge-droit : 0 ; mso-para-marge-bas : 10.0pt ; mso-para-marge-left : 0 ; ligne-hauteur : 115 % ; mso-pagination : widow-orphelin ; police-taille : 11.0pt ; famille de police : « Calibri », « sans-serif » ; mso-ascii-font-family : Calibri ; mso-ascii-theme-font : minor-latin ; mso-hansi-font-family : Calibri ; mso-hansi-theme-font : minor-latin ; mso-bidi-font-family : « Times New Roman » ; mso-bidi-theme-font : minor-bidi ;}

  &(!pc_Windows_ehkeyctl|pc_XP_MCE_KB973768_MS09-037) (red indicates failure)

  The NAC is reported as a check failed:

  pc_Windows_ehkeyctl, File Check [$SYSTEM_ROOT\ehome\ehkeyctl.dll is]

  It is a failure because it finds the file and there is a negative on the rule?

  What about this:

  / * Style definitions * / table. MsoNormalTable {mso-style-name : « Table Normal » ; mso-tstyle-rowband-taille : 0 ; mso-tstyle-colband-taille : 0 ; mso-style-noshow:yes ; mso-style-priorité : 99 ; mso-style-parent : » « ;" mso-rembourrage-alt : 0 à 5.4pt 0 à 5.4pt ; mso-para-marge-top : 0 ; mso-para-marge-droit : 0 ; mso-para-marge-bas : 10.0pt ; mso-para-marge-left : 0 ; ligne-hauteur : 115 % ; mso-pagination : widow-orphelin ; police-taille : 11.0pt ; famille de police : « Calibri », « sans-serif » ; mso-ascii-font-family : Calibri ; mso-ascii-theme-font : minor-latin ; mso-hansi-font-family : Calibri ; mso-hansi-theme-font : minor-latin ; mso-bidi-font-family : « Times New Roman » ; mso-bidi-theme-font : minor-bidi ;}

  &(!pc_XP_2115168_MS10-052_FileChk|pc_XP_2115168_MS10-052)

  The first part of the reports as passage, and the second reports failure... but logically, this part of the rule must pass because only after the first part?  Which apparently correct?

  Thank you!

  Gavin - Budd

  He actually reports a failure audit - and in many cases, it is expected (and confusing!).  For example, with Windows controls preconfigured, if it is a 32-bit client you will see fail the verification of 64-bit.

  Same with your second example check

  &(!pc_XP_2115168_MS10-052_FileChk|pc_XP_2115168_MS10-052)

  We expect that it is not the first cheque or spend the second control - but one of these controls will show as failed.  Clear as mud?
