switch 3750 EAPoL transmission RADIUS server

I have a running version of the 3750 switch stack 12.2 (53) SE2 IPBASEK9-M. I have dot1x configured on the switch and a Windows 7 PC, connected with 802. 1 x configured on the interface. I see the EAPoL start message from the PC, but I do not see the packets from the switch to the RADIUS server RADIUS. I have a config simple dot1x just to try to make it work before adding additional features such as comments - vlan...

Config and debug of attached file.

I don't know if the configuration ip dhcp snooping and arp of inspection is cause a problem with that or not. I see the EAPoL packet received on the switch, as shown in the attachment of debugging, but I never see the RADIUS packet. I've defined both trust on the interface, but always the same result. I can't turn it off because there is a switch of production with a test interface.

Any ideas?

Thank you

Mark

I had the same problem and solved it is enough to configure the switch as authenticator instead of "supplicant". "Supplicant" means customer, "authenticator" means in fact the switch acts as an authenticator to pass through, it will forward the requests to the auth server, for example, host of RADIUS.

    Have you run wireshark on the server because the request to switch? If so you make sure that there is a response from the server? For Windows network POLICY Server (I've never tried Centos), you must ensure that the request is related to a policy which then authenticates, or denies access. Usually, it is a matter of such attributes and the seller.

    Regarding the configuration, it seems a bit out of the AAA. Try to remove the:

    line "aaa dot1x group service radius authentication" and this by using instead:

    "aaa dot1x default radius authentication group". After the dot1x word you are supposed to provide a list of the authentication or the default Word if you do not want to use a list.

  • How to restrict Internet access by using the RADIUS server via switch Catalyst 3560

    Dear all,

    I need a configuration using any. I have a small network of 15 users a 3560, which is in turn connected to a router ISR 2811. Interface fastethernet 0/24 switch 3560 I intend to connect to a unix based server RADIUS. ISP is connected on the opposite side of the 2811 to the fa0/0 interface.

    I want to make is that if someone among the 15 users tries to access the internet, they must be validated in the RADIUS server by their pre-configured user credentials. (I'm going to store 15 user credentials here). If someone else tries to connect (except those 15) he or she should be denied internet access.

    The RADIUS server will be having a login page to type the name of user and password.

    Please guide based on what commands I should inject into the 3560 or what specifically, I need to have to run this task.

    Thanks in advance!

    Samrat.

    I only did this in a very long time, but you probably want to do is activate the web authentication.

  • Dell Powerconnect 35xx series features Radius Server behaviorfin

    Hello Dell Community,

    I'm not able to find out how 35xx series switches handle 'server radius deadtime' parameter as described below:

    In the config of switch, I use two hosts(for redundancy) radius. The first has priority of '1' configured RADIUS, the second server is priority '2 '. So normally, if the first sever(priority 1) RADIUS online, auth requests switch are sent to this server all the time. And they really are.

    Now, I have also configured the 'deadtimet 10 radius server', meaning to jump on the radius server does not respond. Does that mean exactly?

    If the radius with priority 1 server is offline for a few seconds, the switch instantly consider this as dead radius server and sent no auth request it for the "period deadtime ' 10 minutes (depending on configuration)? How often switch check for the availability of the radius server host?

    config swtich:

    IP address Port port Prio time - Ret-dead-source IP. Its use
    AUTH Acct Out rans times
    --------------- ----- ----- ------ ------ ------ --------------- ----- -----
    10.10.10.10 1812 1813 global Global Global Global 1 all the

    Waiting period: 2

    Deadtime: 10
    Source IP: 0.0.0.0

    Retransmission will say the switch many times in an attempt to authenticate to the RADIUS server before moving on to the second server. Timeout is indicative of the switch, the waiting time for a response. Deadtime will subsequently intervene in these two parameters have been exhausted.

    Example config:

    Server radius coverage of console (config) # 3

    Console (config) # timeout 3 radius server

    Deadtimet console (config) # 10 radius server

    Result of config:

    -The client tries to connect.

    -switch attempts to authenticate the server 1.

    -Switch means no RADIUS server 1 for 3 second.

    -Switch waits 3 seconds.

    -Switch attempts to authenticate to the RADIUS server 1 for the second time and does not return to server for 3 seconds.

    -Switch waits 3 seconds.

    -Switch attempts to authenticate to the RADIUS server 1 for the third time and does not return to server for 3 seconds.

    -switch place RADIUS server, one in a State of low/dead for 10 minutes.

    -switch attempts to authenticate to Server 2.

  • Primary/secondary RADIUS server

    Hey all,.

    I tried to find out for awhile how primary and secondary RADIUS servers work about WLC 4400 s. If the primary RADIUS server goes down, and the secondary image is used, when the controller will return to the primary once it is up? He waits until the secondary breaks down, or done immediately switch back to the primary when it becomes available?

    Thanks in advance!

    The f

    On versions 4.2 and earlier, if the principal fails, then the secondary image is used until the secondary level is not available. So if you want the main for the radius server to use purpose, restart the secondary image. Then the tertiary then back to the primary. 5.0 has a feature in which you can define a Dungeon alive so that when the primary comes back upward, the primary will be used again. 5.0 code not a version of good code, however.

    the configuration of switches is less than

    existing Ganymede:

    host key 10.11.11.40 radius-server 9090897979800090908

    Now I move the server to a new IP 10.99.1.40

    If I put the command

    host key 10.99.1.40 radius-server 9090897979800090908

    the configuration looks like this:

    host key 10.11.11.40 radius-server 9090897979800090908

    host key 10.99.1.40 radius-server 9090897979800090908

    I need to confirm that when I switch the server again this IP switches will turn to the new ip address of 10.99.1.40 and I do after all, that is, remove the old line: no host key 10.11.11.40 radius-server 9090897979800090908

    http://www.Cisco.com/c/en/us/TD/docs/iOS/12_2/security/configuration/guide/fsecur_c/scftplus.html

    Thank you very much

    The method explained in the linked document is the most recent. On IOS 15.x the previous method (which still works) generates a message in the cli parser that it was withdrawn and Cisco recommends to the new method.

    That said, each method should work. The new method should be good all switches or routers with IOS 12.0 +.

    When there are two servers configured, IOS them will try in order and, if a response is not received in three trials (each in the case of multiple servers), it may fall to another configured method aaa (or fails aaa if no second method has been defined)

  • RADIUS server for authentication

    Hello

    I want to configure the radius server, so whenever someone tries to connect to a cisco (Telnet) switch, I want the radius to authenicate them server. Is this possible?

    Yes it is possible as long as you configure your switches to authenticate to the Radius server. To achieve this, you must use a feature called AAA. This feature is compatible with the protocols such as Radius, GANYMEDE +, to name a few. The following link will give you an idea on how to set it up on switches IOS based specifically on the 3550:

    http://www.Cisco.com/en/us/partner/products/hw/switches/ps646/products_configuration_guide_chapter09186a00801a6b15.html

    Make sure that apply you the authentication list to the vty lines to ensure that telnet access is authenticated with the radius server. FOT based CatOS switches than the following link will be useful:

  • privilege level of the AAA RADIUS server control

    I had the radius authentication on my switch, but I'm trying to allow two types of connection of users using Windows Active Directory. NetworkUsers that can display the configuration and NetworkAdmins who can do what either. I would like to NetworkAdmins when they log on, go directly to the privilege level 15 but could not get that part to work. Here is my configuration:

    Domain controller for Windows 2008 R2 with NPS installed.

    RADIUS client: I have the IP address of the switch as well as the key. I selected under the name of the Vendor tab in advance of cisco

    Network policies:

    NetworkAdmins which has the Group networkadmin in conditions and under settings I have nothing the standard and for the individual seller I have:

    Cisco Cisco-AV-pair shell: priv-lvl = 15

    My config switch:

    AAA new-model

    No matter what I do, it is not the default privilege level 15 when I login. All thoughts

    You have specified the permission under line vty group? I think it is the authorization exec command. Something like that.

  • Test of the RADIUS server options

    Hello

    Does anyone have experience in the radius server availability tests? I have what the switch is used to test the availability of the radius server and what measures he will take after the detection of server are dead? Setup is done with ISE 1.4.

    Hello

    Because how switch contact RADIUS and how to configure the switch for dead timers, I will redirect you on the Cisco documentation which is very simple and complete as well.

    http://www.Cisco.com/c/en/us/products/collateral/iOS-NX-OS-software/iDEN...

    All parameters to mark a server as dead and how long it will be considered as dead are tweak-able. Setting dynamically some servers as dead if no responses may result in better performance of RADIUS response.

  • Secondary RADIUS server

    I need help on setting up a secondary RADIUS server. I have a primary and secondary school. I would like AAA sending requests to the secondary server when the primary is either down or stopped service on the primary. Any ideas?

    You should consider two methods:

    The old school one like that.

    AAA new-model

    AAA authentication login default group Ganymede + local

    !

    radius-server host 10.1.122.11

    radius-server host 10.2.32.13

    If not, try a method of group like this:

    AAA new-model

    AAA server Ganymede group + ABCGROUP

    Server 10.1.1.5

    10.1.1.13 Server

    !

    ABCGROUP line group AAA authentication login default

    !

    GANYMEDE-Server 10.1.1.5 host

    radius-server host 10.1.1.13

    RADIUS-server key abcdef

    !

    Because the shared key (secret) cannot be configured in the configuration group, you must define RADIUS servers again at the end of the config.

    !

    Make sure that you have connectivity at a time before testing. Stop the service on your primary ACS and keep an eye on the reports to see the authentications spent in vain.

    Here; s another tip:

    By fallback authentication 'line', you can immediately distinguish a line Login and Ganymede Login. GANYMEDE will show: "username:" and encourages you to line "password:
