• The AAA authentication and VRF-Lite

  Hello!

  I encountered a strange problem, when you use authentication Radius AAA and VRF-Lite.

  The setting is as follows. A/31 linknet is configured between PE and THIS (7206/g1 and C1812), where the EP sub-si is part of a MPLS VPN and VRF-Lite CE uses to maintain separate local services (where more than one VPN is used..).

  Access to the this, via telnet, console etc, will be authenticated by our RADIUS servers, based on the following configuration:

  --> Config start<>

  AAA new-model

  !

  !

  Group AA radius RADIUS-auth server

  Server x.x.4.23 auth-port 1645 acct-port 1646

  Server x.x.7.139 auth-port 1645 acct-port 1646

  !

  AAA authentication login default group auth radius local

  enable AAA, enable authentication by default group RADIUS-auth

  ...

  touch of 1646-Server RADIUS host x.x.4.23 auth-port 1645 acct-port

  touch of 1646-Server RADIUS host x.x.7.139 auth-port 1645 acct-port

  ...

  source-interface IP vrf 10 RADIUS

  ---> Config ends<>

  The VRF-Lite instance is configured like this:

  ---> Config start<>

  VRF IP-10

  RD 65001:10

  ---> Config ends<>

  Now - if I remove the configuration VRF-Lite and use global routing on the CE (which is OK for a simple vpn installation), AAA/RADIUS authentication works very well. "" When I activate transfer ip vrf "10" on the interface of the outside and inside, AAA/RADIUS service is unable to reach the two defined servers.

  I compared the routing table when using VRF-Lite and global routing, and they are identical. All roads are correctly imported via BGP, and the service as a whole operates without problem, in other words, the AAA/RADIUS part is the only service does not.

  It may be necessary to include a vrf-transfer command in the config of Group server as follows:

  AAA radius RADIUS-auth server group

  Server-private x.x.x.x auth-port 1645 acct-port

  1646 key ww

  IP vrf forwarding 10

  AAA new-model

  AAA authentication login default group Ganymede + local

  AAA - the id of the joint session

  RADIUS-server host 10.4.4.21 single-connection

• FSCA - recording in privileged Mode

  I configured a single client, the remote agent and ACSE. I am able to authenticate on the device via AD network. He invites me credentials, then I'm in user mode. I then issue the enable command to enter privileged mode. He invites then authenticate again. My question is how to configure ACS to make me enter directly into privileged mode, once I've authenticated? I do not want to be first in user mode then need to authenticate again to enter privileged mode. Any help would be greatly appreciated. Thank you!

• Activate the ASA system context AAA authentication

  Hello!

  We have ASA configured in multiplayer in context with 8.4 (2) software configured for AAA

  Configuration is admin context as follows:

  AAA-server TAC Protocol Ganymede +.

  host of the TAC AAA-server 10.162.2.201 (management)

  key *.

  Console to enable AAA authentication LOCAL TAC

  TAC LOCAL console for AAA of http authentication

  AAA authentication serial console LOCAL TAC

  authentication AAA ssh console LOCAL TAC

  Because of the multiple context, after the connection we enter in the system context. Console port authentication works very well except access to the privileged mode when you connect through the console port.

  After the show 'enable' command ASA accepts only configured activate secret in context and change ID of user system for enable_15, so we are unable to do accounting and authorization of user level control.

  It seems that the ASA in the context of the system is not aware of all the configurations of AAA, and it is not a command to configure AAA in the context of the system.

  Is there a way to configure enable AAA authentication in the context of the system?

  Thanks in advance!

  Hello

  It looks like you hit this known issue that follows:

  http://Tools.Cisco.com/support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsw18455

  Admin context allow mode compared to the context system DB credentials

  Symptom: In multi-mode configuration, the user to enter privileged mode credentials (enable mode) via the serial console is not sent to an external server role of authentication. Conditions: ASA/PIX is in multi mode. serial console and activate the console authentication are configured to use external aaa server in the context of the admin. Workaround solution: Option 1: Configure enable password in the system context. Option 2: Avoid the use of the interface of the console series and rely on telnet or ssh console access.  SSH or telnet consoles, tries to enter active mode is authenticated as specified by the configuration of aaa in the context of "admin". Other Description of the problem: When authentication is enabled for the serial console and activate console in Executive admin via an external aaa Server (for example: radius or Ganymede +), series Console OmniPass is against the external aaa server, but the mode credentials are compared with enable db in the context of the system.

  Hope that clarifies it. Unfortunately there is no solution for this problem.

  Kind regards.

• GANYMEDE + authentication and authorization on IOS XR

  Hi all

  I tried to connect several devices IOS - XR on our laboratory (ASR, RSG and CRS) to our server GANYMEDE + (Cisco Secure ACS, release 4.2 (0)).

  Lior

  Lior,

  You must return the task ID and/or groups of task in order to make this work. According to my experience, working with these platforms is it is really unnecessary to proceed with approval of order if you trust the task-ID/groups, which are integrated in the ASR.

  The flow for Ganymede command auth for these devices is a bit different than your IOS essentially traditional (unless something has changed in the last 6 months), if the user tries to run a command, the Ganymede auth command is triggered if the user executes a command that falls under the umbrella of task. If she's not here command permission is never triggered.

  Here are some documents that I feel will help you:

• issue certificates of 802. 1 x authentication and X 509

  Hello

  Can someone please help me with the following question:

  First off I am a guy from Windows Server/PKI/AD etc. rather than CISCO, even if I have a CCNA :)

  I take care of PKI to my company and will work with the team CISCO that are the introduction of CISCO's ISE, we will use X 509 CERT on the suppliants (desktop/laptops Windows computers mainly)

  What I want to know is something pretty basic, but I saw not written anywhere

  Question 1:

  First stop, I guess it's the AAA (ISE) server is the entity that verifies the pleading certificate X 509, rather than the AP (access wireless router for example point)? is that correct

  Question 2:

  As supplicants X 509 certificate is public (for example, it is not secure and anyone can ask what it is normal) I guess the AAA server must encrypt a (random number for example) value with the public key of supplicants (of the X 509 cert) then send this value to the supplicant by which the supplicant decrypts with its private key (that no one else has as usual). Then the supplicant figure the value even with servers AAA public key (which is held in servers announced AAA X 509 cert) cela send on the AAA server and once that deciphers AAA server (with its private key) if the value matches the value originally sent to the supplicant then the AAA server can continue with authentication etc.

  The above assumption is correct?

  If the above is correct, not ISE always act like that or can you lower the security and get just the ISE server to check whether he trusts the issuer of the certificate (CRL does OK) the pleading X 509 Cert and not bother to send the encrypted packet as described above (this of course would ensure not begging-1 is actually "supplicant" - 1).

  Thank you very much in advance

  Ernie

  Answers:

  1 - Yes, ISE verifies the certificate presented by the device of end-user (begging) against his PB of authority certificate TRUSTED internal to import in ISE root and intermediary certificates where you use CA non-public servers (this is my case for EAP - TLS) such as Verisign, Entrust, etc. UNFORTUNATELY, ISE allows you only to have 1 cert for the use of EAP in the list (PEAP, EAP - TLS, etc.), which means that you CAN not EAP - TLS and PEAP running on different SSID. The problem is now that Entrust for example use an intermediary called L1K Entrust which is not included in trust for the devices Apple and Win 7 CA. This causes a certificate not approved for IPADs warning then you need to trust this certificate but for Win 7 features the PEAP TLS Tunnel, Setup will fail if the connection cannot be established if you uncheck "VALIDATE SERVER" on Win 7 for this SSID profile.

  2 - you can create a condition that validates the issuer cert but the authorized Protocol is EAP - TLS or PEAP so that the actual process for one of these protocols, based on my understanding is actually. For example, Protocol PEAP, the configuration of the TLS Tunnel is the 1st step, so once the configured secure tunnel then the inside MSChapv2 + EAPOL is performed and finally the data passes through the tunnel

• banner of AAA authentication

  I have configured the banner authentication aaa and aaa fail message on a router running 12.1 (15) - authentication is done by ACS 3.0.2 which works very well.

  Problem - the banner of authentication does not appear (nothing is outside of "username:"-don't not even 'check' user access) If you enter a wrong password, but the failure message. If I console in and unplug the interface while the two messages very well.

  Workaround solution - if I set up a connection "banner" then everything works fine too, but I can't work out why does not display the "banner of aaa authentication."

  I suspect ACS prevents the message, but I can't work out how - can anyone suggest a solution?

  Thank you very much!

  By the way that the command "radius-server administration '? It doesn't seem to be documented, and it has no effect or not.

  The banner command does not work if you make the RADIUS authentication, it will not work if you do a RADIUS/local/etc. This is normal, cause with Ganymede you can have the sending server banner and guests down (even if with all I don't think that you can do) and so if you have configured authentication GANYMEDE the router does not take into account the banner command and waits to see if she gets a new one from the server RADIUS itself. If it is not it will simply display the usual guests.

  As for the 'radius-server admin' command, honestly, I have no idea, never seen anyone use. Online help says "start the daemon of Ganymede management administrative messages", but what really I don't know, maybe someone else can help.

  aaa IP http authentication

  radius-server host 10.161.161.20

  111111 radius-server key

  It must be something with the fact that on http or ANC, it connects to the router at level 15, but I have played with all sorts of orders of different authorization and cannot operate.

  Paul

  What you want to do for authentication if the RADIUS server is down? For telnet and console access you can use the line as a backup method because it is possible to configure a password for the line on the console and vty ports. Which type of backup method you want for HTTP? The one that seems most logical to me would be to a local authentication in order to cover the situation where the server is down.

  To use local authentication, you must do the following:

  -create a definition of the local user (maybe more if you need extended security).

  -specify a special method for authentication of the aaa.

  -specify that http, using the special method.

  The configuration might look like this:

  password user tech1 tech1

  AAA authentication login http_auth group Ganymede + local

  IP http authentication aaa - authentication of the connection http_auth

  Or you can decide to use the secret to activate (or password that is configured in office). The config might look like this:

  AAA authentication login http_auth group Ganymede + activate

  IP http authentication aaa - authentication of the connection http_auth

  If you want a different backup method, let us know what it is and we'll see how it could be implemented.

• No AAA authentication for switch

  I'm intrigued by my question. I have a switch on 9 that cannot authenticate with our server GANYMEDE. The configurations are the same as any other switch, but when I try to open a session using the account GANYMEDE + access is denied. This is the configuration for the AAA/GANYMEDE on the switch.

  AAA new-model

  AAA authentication login default group Ganymede + local
  authorization AAA console
  AAA authorization exec default group Ganymede + local

  radius-server X.X.33.XX host
  radius-server key 7?

  I deleted the aaa configuration and then reconfigured it as well as the information from the server RADIUS and no authentication Ganymede. I gave the Ganymede interface should use, but same result. Any ideas?

  Thank you

  Robert

  Robert,

  Please make sure following

  -Radius server is accessible from the switch and port 49 is not blocked.

  S ' it is layer 3 switch, then make sure to configure the interface source ip Ganymede XXXX (Interface IP set in radius server)

  -Check the secret key

  If the problem is still there then please get
