• WLC with RADIUS authentication servers

  I WLC user authentication with Cisco ISE which is linked with LDAP, now ISE is not accessible. Will be wireless users could always connect and use the Services of WLC?

  Hello Irshad-

  All customers who have already been authenticated will continue to work and to be allowed on the network until they leave the network and/or re-auth, idle, etc type timers expire. At that point, customers will not be able to join the SSID and won't have access to the network.

  To avoid that from happening, you can:

  1. create a redundancy by having more than one node of ISE

  2. create a secondary authentication via another RADIUS or LDAP server

  I hope this helps!

• WiFi WPA2 Enterprise with RADIUS - connection problem

  Hello

  I have here a new ISA 570w with the latest firmware (1.2.17).

  Anyway, I can't get wifi to work in mode WPA2 Enterprise with RADIUS authentication.

  Mode WPA2 PSK are not a problem.

  I have configured the BEAM properly and I can connect directly to him via NTRadPing without any problem. Also the test in the web interface works without any problem (see Figure 2, 3).

  The RADIUS server is a server Synology RADIUS on a Synology NAS, which is a FreeRADIUS server under the hood.

  In the settings of the ISA wireless, I put this RADIUS server for authentication (see screenshot 1, 4).

  However, I can not connect to connect to the network:

  On the iPhone (iOS 6.1.3) I get a prompt for a user name and password, but when I click on connect, it says 'connect to 'cisco3'... ". "and stays there.

  In ISA 570w newspaper, he said:

  Information

  Wireless

  MSG = add MAC station in the list of the ATU. VID = 5; MAC = 5 C: 59:48:02:78:3E;

  Information

  Wireless

  MSG = Wireless mode is a 802.11 mixed b_g_n

  When I cancel the connection attempt, he said:

  Information

  Wireless

  MSG = the Client has dissociated;

  On my Thinkpad with Windows 7 Professional I have everything configured as usual (see screenshots 5,6,7,8) but when I try to connect I do not get a command prompt where I wonder username and password, and finally the connection cannot be established (see Figure 9). Also tried with the same configuration on an another Windows 7 Pro installed costs for laptop with the same problem.

  I can't see any attempt of 570w ISA to authenticate anything in the logs of the RADIUS.

  Also the capture of network traffic on the LAN to the Synology NAS port does not show the RADIUS datagrams.

  I already disabled COP because I read that it can cause problems, but it did not help.

  Can you please suggest something else I can try?

  Thanks in advance!

  Kind regards

  I saw these screenshots, but that screen settings just select the button set up next to the authentication method in the section user authentication, under users.  In each of your screenshots, the RADIUS server identification number is 1, so I would also ensure that I configured the server ID RADIUS 1 that can be configured by going to users-> RADIUS servers.

  All that said, I have seen that your tests have passed and I also do not understand the point of having the RADIUS settings on other screens and then to have info ID RADIUS.  My thought is that you'd be able to pre-set RADIUS users of-> screen RADIUS servers and then select the RADIUS server ID in all other screens without having to enter the RADIUS news over and over again.  He also thinks that you could ignore the users-> screen RADIUS server and enter RADIUS information over and over again and it should work... as you set up initially.  However, based on the past experience of programming errors, I recommend configuring the ID from RADIUS server 1 under user-> RADIUS servers if you have not already... just in case where.

• Authentication Radius Cisco with Windows NAP with encrypted authentication

  I need authentication radius configuration for Cisco IOS devices for device management. My radius server is on Windows 2008 R2.

  Can I implement this with encrypted authentication? In the attached diagram, can what protocol I use for encrypted authentication?

  According to some sites, we need activate authentication in clear text. All those put in place secure as MSCHAP authentication?

  Hello

  You activate the text authentication (PAP) clear. Don't forget Ray sends the username in clear but encrypts the password. You can confirm this take a wireshark capture. You will also get the RADIUS encryption using a key to Ray long and complex.

  If you want to encrypt the user name and password, then you would use GANYMEDE

  Thank you

• RADIUS authentication for the switch using ISE

  Hi guys,.

  Someone did he do Radius Authentication for switch cli connection using ISE?

  We did it in our environment with ISE, but it is a challenge to give read-only access / Priv-1.

  If some users know the enable password, they can use and earn full privilege.

  Anyway to get around this other than to change the enable password?

  We have thousands of switches and won't change on each of them.

  If you have another method please advice.

  Thank you in advance.

  Well, you can set the "enable" function also be controlled via the AAA server with the following command:

  AAA authentication enable... This way server AAA will be checked for authentication for the secret to activate and use the local database as a last resort

  I hope this helps!

• 5.2 ACS with different RADIUS authentication servers

  Hello

  I want to migrate from ACS ACS 5.2 4.1. I have already configured authentication GANYMEDE +, but now I've stuck to the RADIUS authentication for remote access WebVPN configuration. Please see the following diagram:

  

  I want to configure ACS to use Server Token WBS first. If authentication fails or the user is not found, ACS must use IAS in Windows Server. If this server fails also ACS must use internal DB. Additional attributes as belonging to a group or ACL downloadable should be taken from internal ACS DB.

  Is it possible to configure ACS like that? ACS 4.1 it is very easy to configure by selecting the per user authentication method.

  Thanks for your help!

  There is an option in the Advanced tab of definition 'RADIUS Identity server' th:

  This storage of identity differentiates between 'authentication failed' and 'user not found' when an authentication attempt is rejected. Among the options below, select how a rejection of authentication of the identity store must be interpreted by FAC for the politics of identity of treatment and reports.
  Releases to treat as 'authentication failed' treat dismisses them as "user not found".

  In order to continue in the sequence, I think you have to select the option "user not found".

• AP541N cluster with Radius UC540 Server?

  Hi, so using the radius in the UC540W Server works a treat if the wireless network comes from the CPU area.

  But if the AP541 is serving the wireless network, I can not RADIUS to work.

  I have removed all my networks in the UC area and have disable the wireless interface (tried with the wireless active too).

  The local RADIUS is active and the installation program on the CPU area.

  But still nobody can join and authenticate!

  Any ideas or advice? Known issues?

  I followed all the directions to a tee!

  Hello Jeremy

  Thank you for contacting the Support Forums of community of Cisco.

  When you use a UC540W with an AP541N, it is suggested to not use the AP and turn off the wireless on the UC540W.

  To use Windows clients, the authentication server must support PEAP (Protected EAP) and MSCHAP V2. How is your Radius server in the setup of UC540W?

  To ensure that the radio itself works OK, can you, or have you tried to do just the WPA or WPA2 with regular encryption. See if you can connect, authenticate and roam the network.

  Please keep us informed.

• WLC with RADIUS question

  Hello

  I have the following strange behavior:

  My WLCs connects to the RADIUS server by using the IP address of a dynamic interface instead of using the IP address of the management interface.

  Dynamic interface Tha is on the same subnet / vlan from the RADIUS server.

  What is the best interface to use for RADIUS authentication?

  And how do I decide which interface shuold be RADIUS-source IP interface to connect with my radius servers?

  Thank you all

  Johnny

  If you have the Radius Server on a subnet in which you have any interface on the wlc on, you will see the wlc by using this ip address. The ip address of the client AAA you should use is the dynamic ip address. The only time where you will see the wlc use its management interface is your wired and wireless (dynamic interfaces) are on different subnets.

• RADIUS authentication question

  Hello world

  I'm learning the Radius Authentication. Here are my updated laboratory in place:

  R1 (107.107.107.10)-(107.107.107.4) - WIN2008 (RADIUS SERVER)

  Here is the config of RADIUS on the R1:

  AAA authentication login default local radius group

  RADIUS-server host 107.107.107.4 auth-port 1645 acct-port 1646
  key cisco RADIUS server

  I have a few questions:

  (1) above, I do not specify encryption on R1, R1 will use this as the default encryption?

  In the attached file, we see the password is encrypted, but there is no config on R1 to use particular encryption

  (2) we also see "authenticator", which is I think is R1 host name i.e encrypted with the shared secret. I'm wrong?

  Much appreciated and have a great weekend!

  Hello

  The Protocol Radius encrypts the password for the default user. I think that Radius uses MD5.

  The authenticator is a random string generated by the client and is used in the encryption of the password process.

  Thank you

• RADIUS authentic works not 3560

  Hello world.

  The switch's config for RADIUS authentic.

  When I try here is the log

  % SSH-SSH2_USERAUTH 5: 'xy' authentication SSH2 Session 192.168.x.x (ATS = 1) using crypto cipher "aes256-cbc" hmac "hmac-sha1' Failed

  What should I check now

  Concerning

  Mahesh

  You must post a few outings until I'd suggest something. If SSH works very well with the local database which means the keys RSA are fine.

  If you can't attach the executed full show. Attach the bottom of the outputs listed in your next reply.

• VPN Site to Site Secret shared and can co-exist RADIUS authenticated VPN?

  Hello

  I have a setup VPN site to site between two offices on 515Es PIX (v.6.2 software) and has recently added a vpngroup/shared secret based VPN remote access to one of the offices. Given that just forced me to add a number of different policies to my existing crypto card, it was a plant direct and easily implemented. For more security, I want to use a RADIUS server to give to each remote user their own connections and profiles rather than a group on all password is configured. To do this, however, it seems that I have to add the following additional commands to my existing crypto card:

  client configuration address map mymap crypto initiate

  client card crypto mymap RADIUS authentication

  These do not correspond to the policy number (my site-to-site is 10, and remote access policy is political 20), so I don't know what the effect would be if I added the. It would cause my connection from site to site for authentication RADIUS request (a very bad thing)? If so, do I need another interface to bind a new encryption card to? The answer to this would be greatly appreciated!

  Also, if anyone knows an example configuration for a similar configuration, I can look at, please let me know! Thank you.

  -A.Hsu

  For the site to site connection, you change line isakmp keys and add the parameters of "No.-xauth No.-config-mode" at the end of this one, which tells the PIX not to do the auth RADIUS or assign an IP address, etc. for the specific site-to-site tunnel.

  Example of config is here:

  http://www.Cisco.com/warp/public/110/37.html

  Note that there is no command options I have just said, I just sent an email to the web guys to fix this. Basically, your config will look with the options "No.-xauth No.-config-mode" on the line «isakmp x.x.x.x key...» "for LAN-to-LAN tunnel.

• AAA with RADIUS of ASA

  Hey everybody,

  I'm with RADIUS AAA configuration on our Firewall remote ASA.  It's pretty simple, but I have some firewall that does not work on.  I upgraded the IOS image on the ASA 5510 to ASA804-K8. BIN on each of them.  The weird part is some of them work and some of them do not work.

  I was wondering if anyone else has encountered this before and what information do you need to give me a reference to help.

  Thanks in advance,

  Kimberly

  Hi Kimberly,

  just curious: why 8.0.4 and not 8.0.5?

  What you use radius for? What is the radius server? You have configured all the ASAs of the radius servers? Did you use the right shared secret?

  Is there something different between the ASAs working and does lack those? Configuration, location in the network, etc.?

  If the above does not help, please post the config of ASA failure (or at least the relevant items and be sure to remove all sensitive data) and the output of:

  Debug RADIUS

  Debug aaa authentic

  Debug aaa 254 Commons

  You can test only the part of RADIUS with the command «test aaa-server authentication cli...» »
