I am trying to get a NAC demo running and am having some issues with a Layer 2 OOB, Virtual GW configuration. Currently I have 3560G switches and would like to assign ports to a vlan based on user roles.
My Auth VLAN is 110 and maps to VLAN 11
Guest VLAN is 11 (172.16.1.0/24)
Employee VLAN is 1
NAS Mgmt VLAN is 20 - CAS is 10.10.20.5 (this ip is setup on both eth0 and eth1 per documentation for L2 OOB Virtual GW)
NAM Mgmt VLAN is 30 - CAM is 10.10.30.5
Untrusted (Eth1) switchport is setup as a trunk allowing only vlan 110 and has a native vlan 999 to blackhole traffic.
Trusted (Eth0) switchport is setup as a trunk allowing vlan 1, 11, 20 and has a native vlan 998 to blackhole traffic.
I also setup a Managed Subnet on the CAS with IP 172.16.1.254 and VLAN 110.Switchport controlled by NAC is access vlan 110. When a machine connects an snmp trap is sent to CAM and is forced into vlan 110. If I try to put the port in another vlan CAM puts it back to 110 immediately. This all seems to be working well.The machine connected to the port gets a DHCP address from VLAN 11. When I initiate traffic from this machine, everything is blocked. If I open a web browser I do not get an authentication page. I also installed CCA 4.1.10 on the machine but it does not find a discovery host and the Login option is grayed out. The only way to get this machine to send traffic is to add a filter for it and force it to the ALLOW option. I did setup a default web login page but I seem to be missing something to get authentication to work. I am running version 4.1.8 with a demo license. The host running CCA is Windows Vista.
I'm responsible for designing the network for a LAN party that will be held in October. There will be up to 400 participants and 25-30 crew members. 10 table rows, 40 participants and one 48-port gigabit switch on each table. Core network will be a couple of Cisco 3560G or similar. There will be 2xGbit between the table and core switches.So, how to set up VLANs and subnets for a 400+ people network?
1) Everything on one /23 subnet, or
2) Participants on one /23 subnet, separate subnets for servers, crew and wireless, or
3) Participants on two /24 subnets, separate subnets for servers/crew/wireless, or
4) Separate /26 subnets for each table switch and for servers/crew/wireless?
As far as I can see, the main disadvantage of all participants on one subnet is troubleshooting and isolating network problems - and the main disadvantages of separate subnets is more complex setup and that people cannot browse LAN games other than those on the same switch.
I'm trying to set up per vlan routing on a 3560G switch but it's not performing as I would expect. I've got a server on the 109 vlan with a 10.1.9.100 address and a default gateway of 10.1.9.1 this address is an HSRP gateway and currently resides on 10.1.9.7. When I traceroute through to my user PC on the internal network it receives a response from 10.1.9.7 However, it is then denied by an ACL on the internal firewall which has been applied to interface Eth0/0. It should arrive at the firewall on Eth0/2.109 as it has the 10.1.9.4 address.
My goal here is to route traffic on the 101 vlan to a seperate interface on the internal firewall from 109 vlan traffic. I'm either doing something wrong or these routing commands aren't designed to work in the way I'm expecting (I couldn't find any documentation on the ip route command where it is followed by different gateways for different vlans)
I have a 5508 wlc trunked to a 6500 switch. Also trunked to the switch on both eth0 and eth1 is the CAS. The CAM is connected with an access port.
The CAS and CAM are on seperate VLANs and the CAS was added to the CAM without issue. I followed the example document for OOB WLAN (VLANs and mapping etc) but I don't get any authentication going on. The client associates and the WLAN interface is the quarantine VLAN However it seems the client can connect to the network without issue (can web browse to a server internaly to the campus)
The client is shown in the wireless clients on the device page of the CAM, If i close down either of the CAS interfaces the client connectivity is broken.
Just once, randomly the Clean Access Login Page appeared on the client (battery had died and waited about an hour) but when I rebooted the CAS to check it was consistent it never came back.
web authenticate users within a specific Active Directory Security Group. I tried to authenticate over Radius with Cisco Secure ACS and Network Access Restrictions. But NAR only works with Layer 2 authentication. And Web Authentication over LDAP can only be used with User Objects.
I am running Cisco ACS 5.1 802.1x with certificate based authentication for Wired and Wireless connections. The issue that I am having is that when a user comes in from home with their laptop the wireless connection works, they pass the authentication and have network access fine. But when the plug the laptop into a docking station the LAN connection fails and gets put in the Auth Failure Vlan. A reboot of the phone/ shut/no shut fixes this, but I really need to find a resolution.This is an intermittent fault and only effects users with both LAN and WLAN enabled. Running ACS 5.1.0.44, all Cisco 3750s - c3750-ipservicesk9-mz.122-55.SE.Certificates are issues by group policy and only using computer authentication.
I was very excited to read about the two factor authentication that Cisco and Verisign offer through the VIP and SA500 series routers. I purchased an SA540 a month and a half ago. I have been on the phone with support of both Cisco and Verisign ever since. It appears no one actually knows how to make the product work. Finally I was told that they have only tested it on an SA520. So I bought an SA520; however, it doesn't work either. How to use the Verisign VIP two factor authentication with either an SA520 or SA540? If so, what is the trick? If not, how is Cisco advertising this product if it doesn't actually work?
I'm able to setup my 3750e switch to login through a radius server with my company user id and password but would like to be able to set it up that when I log in it drops me on the enable prompt. Right now I have to type >en.Then the enable password.
I am having ACS 4.0.2 in my network, which I want to use for 802.1x Radius Authentication for Clients on PEAP-MSCHAPv2 methodology.As per the documentation " EAP Authentication with RADIUS Server", Doc ID: 44844.I have configured Network Configuration and populated AAA client IP range and Secret Key.
Question1: Under Authenticate Using option, there are various RADIUS flavors available for selection. For a Non Cisco AAA client, should I select RADIUS IETF?
Question 2: In the above snap shot, It has an option called Global Authentication Setup, where we can setup EAP configuration. Under PEAP subsection there is an option to "Allow EAP-MSCHAPv2" check box.After checking that, is a restart required to the ACS Server? Would it cause any disruptions to the existing services on the ACS?
We have configured an 2801 to aggregate some VPN clients. The problem is that between 20 and 50 minutes it asks for re-authentication even though the connection is not idle. Is there a timer that creates this problem?
I have one Fortigate 200B Fire wall, which is using for wifi internet. i had configured one login page in the fourtigate .The path following below system > config > replacement message > authentication > login page.
it was working earlier. suddenly its not working. when i checked this path, that login page message colum was blanked. when i trying to put the message again its not pasting and am unble to type the message also.
I want to setup the ACS 5.1 for dot1x-Port authentication. I want to make a machine authentication against an AD-Domain and I got the following error Message:24435 Machine Groups retrieval from Active Directory succeeded
Is it possible to setup a Cisco 1200 AP with 802.1x to drop users into the corprate network if they have a certificate or if not to put them on the guest network?
im having trauble when using chap as authentication for my two routers, i dont know whether my configuration is wrong or not.Is theres anything wrong with the configuration ??note : both routers are c2961
I have a dot1x client with client certificate working well with my ACS 5.2 and EAP-TLS. Now I would like to configure the Re-Auth periode on the ACS 5.2, I did the following:
1. Configure a Access Profile with Reauthentication Timer = static and 30 seconds (see attachment ACS1.png and ACS2.png)
2. Enabled authentication periodic and authentication timer reauthenticate server on switchport
i tried to create a customized web-authentication page that will re-direct any user to the web-page once they are connected to the network.
The problem is, i just cant attach/upload the image of the logo into the customized web-page (welcome/login page).Been researching about it, found and tried some clue bout it on cisco documentation, but still can't solve the problem.
I am trying to setup EAP-TLS authentication for my wireless access points, but I can't sign my ACS certificate with my enterprise CA certificate.If I generate a self-signed certificate on the ACS server, and try to sign it on my CA, I get an ASN tag error. It looks like that is because the ACS server is not in the certificate path of the CA server.If I generate a certificate on the CA and try to import it into ACS, I get a "unable to parse certificate" error. Is there a way to edit the Certificate Trust List in 5.2? It looks like that was possible with 4.2, but not with the latest version.
I'm trying to set up a 5505 (running 8.3) so that i can use the client vpn through RADIUS authentication.I have set up a new local RAIDUS windows box and used the ASDM asistant and a few other guides to setup the 5505.
I was attempting to setup our 7204 Cisco router to use RADIUS for authentication via the AAA commands. I must have messed up when configuring it as it comes up via TELNET asking for a username and password but doesn't take my AD credentials. How might I login to this router to fix the config? Do I need to do a password recover process?
One note, I didn't save the running-config to startup-config, so if I restart the router will it load the startup-config, thus overwriting the running-config that wasn't working?
I have a 5508 controller running 7.4.100 and have a WLAN where I have radius configured. On my controller the client machine I'm using appears but the radius authentication doesn't appear to be working. Is there anything on the controller I can do to verify that the request is even being sent to my Microsoft IAS server? The log on the server doesn't show any requests from the controller so my early days guess is the controller isn't actually sending it.
I am trying to set up SSL VPN with two-factor authentication on an ASA5510 with software version 8.0(4). I want to use LDAP for actual authentication and user mapping, but require a valid certificate signed by a particular local CA to connect.I have imported the CA's root certificate, signed an identity cert for the ASA box and imported, and assigned the cert ("trustpoint") to the outside interface.Under the connection profile itself (for DefaultWEBVPNGroup), there is an option to select authentication method as AAA, certificate or both. AAA works as expected, authenticating against LDAP. If I select certificate or both, I get rejected with Certificate Validation Failure regardless of if I have a valid signed cert or not. This is what I see with "debug webvpn 100":
webvpn_portal.c:ewaFormServe_webvpn_login[1904]webvpn_portal.c:http_webvpn_kill_cookie[682]webvpn_portal.c:ewaFormSubmit_webvpn_login[1964]ewaFormSubmit_webvpn_login: tgCookie = 0ewaFormSubmit_webvpn_login: cookie = c98f3940ewaFormSubmit_webvpn_login: tgCookieSet = 0ewaFormSubmit_webvpn_login: tgroup = NULLTunnel Group: DefaultWEBVPNGroup, Client Cert Auth Failed!Embedded CA Server not enabled. Logging out the user.webvpn_portal.c:ewaFormServe_webvpn_login[1904]webvpn_portal.c:http_webvpn_kill_cookie[682]
So, it seems the ASA is only trying to check the cert against a (nonexistent) ASA-based CA. How do I get it to check against an external CA cert?Under "Remote Access VPN -> Network (client) Access -> AnyConnect Connection Profiles", I have ticked "Allow Access" and "Enable DTLS". There is also an option "Require client certificate" which doesn't seem to do anything - whether or not I check it, I can connect and authenticate to the VPN with or without signed certs as long as the previous setting is "AAA".

I am in need to setup a VPN tunnel to a vendors hosted network for AD authentication.To prevent RFC1918 Address overlap we are trying to NAT into a VPN Transit Network.I was given 209.235.17.232/19 and need to NAT these addresses:
Currently my side is trying to initiate the tunnel, but we are getting this message:
15 IKE Peer: 65.168.255.157 Type : user Role : initiator Rekey : no State : MM_WAIT_MSG2
I am configuring the transit network for the tunnel properly or performing the NAT for my 2 devices.I am still trying to determine what device the Vendor has on their end.
We are setting up a new office and I am trying to get RADIUS setup for authentication to my switches and routers. Currently I am working on a 3750 running IOS 15 and getting hung on what I think on something small. I have attached my Microsoft NPS Network Policy. Below is my IOS config:
aaa group server radius corp-radius server 10.15.10.20 auth-port 1812 acct-port 1813 ! aaa authentication login default group corp-radius local aaa authentication login radius-localfallback group corp-radius enable aaa authorization exec default group radius
I am enabling our wireless controllers to use 802.1x authentication for our wireless clients. Both computer and user are provided with certificate from CA server.I have 9 APs and 2 controllers installed in my infrastucture, one of the controllers is working fine with setting specified above but the other one is not.Both has same configuration and both seems identical with same model and IOS.
I'm on an ASA 5510 running 8.2(5)41. I have clientless WebVPN configured to authenticate against an RSA RADIUS server, which has users assigned to RADIUS Class attribute 25 to match the group-lock values assigned to each ASA group-policy. This of course is to ensure users can only access the login page's drop-down VPN profiles they are assigned to by the RADIUS server. I have two other ASA 5510s (same code level) using the same RADIUS server with group-lock enabled but for IPSec remote access VPN's, and the group-lock feature works fine.
WebVPN, however, is authenticating any user to any VPN profile without regard to the RADIUS Class attribute 25 they are assigned. If I configure the VPN profiles to authenticate locally and assign group-lock to individual ASA user accounts, group-lock works. As soon as I point it back to the RADIUS server, group-lock does nothing. From the 'debug aaa' below for user 'corpvpnstp', you can see the RADIUS server sends back the attribute 25 values of "ou=stp.Client;" and "ou=stp.ClientDRC;" for this user. The ASA profile this user has attempted to connect to is "EMS-Admin", which should get denied by the ASA. Instead, the ASA successfully authenticates the user.
I have issue with 2950 switch dot1x config is not working , but on 2960 its working fine .Below are the configs from both switches and a debug dot1x all snap, what may be the issue with 2950 switch ...

My switches are able to successfully authenticate user access against ACS 5.1 via SSH with TACACS+, but I am not able to authenticate via HTTPS with TACACS+. I don't even get a log in ACS when attempting to authenticate via HTTPS.
Here is my AAA config, followed by a debug:

on the followup the document "Configuration example : central web-authentication with a switch and Identity Service Engine" by Nicolas Darchis, since the redirection on the switch is not working.
I'm using ISE Version : 1.0.4.573 and WS-C2960-24PC-L w/software 12.2(55)SE1 and image C2960-LANBASEK9-M for the access.
The interface configuration looks like this: interface FastEthernet0/24 switchport access vlan 6 switchport mode access switchport voice vlan 20 ip access-group webauth in(code)
We have a Catalyst 3750 switch that failed over to local login after the Tacacs authentication stopped working. I went through the configuration settings and everything appears to be identical to another switch in this same building.
I'm trying to setup a SSL VPN on a 2811. I believe I have the SSL VPN portion understood, but I can't tell because I keep getting stuck on the Certificate Server, ca trustpoint and identity trustpoint configuration.
guide that walks you through the CA cert, Cert Server, ca trustpoint and identitiy trustpoint to ios SSL VPN?
