Cisco :: WLC 5508 External Web Authentication Mismatch With Session Timeout?
Aug 27, 2012
For guest clients , we have configured guest vlan and applied external web authenication on WLC 5508 , the session timeout value is 2700secons . When a client open a browser to internet page , wlc will redirect to URL and get the login page . After completed the login , he can go to internet page .
We find the iPhone and ipad clients will get the login page again ahfter ~ 5 mins , it is mismatch with session timeout value 2700 sec (45 mins) .

I have inherited the support of an ASA5520 running 8.0(3)12 code and I believe I have a pretty simple question here that I haven't been able to figure out on my own. I have a few users that connect to the box via IPSEC VPN client connections. They want to be able to leave up a RDP based connection, for monitoring purposes, for a most of the day, but thier RDP connection keeps getting discounnted after a few hours. The VPN connection never gets disconnected, just the RDP session running through it. I have another box running 8.0(4) code and they can leave up the RDP sessions as long as they like without getting disconnected from the server(s). I have compared the configs of both boxes and don't see any glsring differences in regards to the configuration that would cuase the RDP sessions to either to stay up or be disconnected after an inactivity type scenario.
What to look for in regards to identifying the timer that is disconnecting the RDP session after a period of time.

We are trying to configure our 2106 wireless lan controller to expire wireless users sessions so the user is not remembered indefinitely. We are using freeradius to validate the users login information and passing back a "session-timeout" avpair but the WLC seems to be ignoring this value.
How to configure the session expiration time of wireless users on a 2106?

We're having trouble trying to deploy 802.1x authentication on a brand new site.
Our primary and secondary ACS are located in Paris and the new site located in Toulouse, France. Both sites are connected through the WAN. Everytime a computer/user connects to this new site in Toulouse, ACS 5.2 sends a "5411 EAP session timeout" error message.

I have a DIR-825 with 2.60VT firmware (rented from Videotron).
Even though the manual says the stateful firewall should have a timeout on connections of 240 seconds or 7800 seconds, all of my connections start at a mere 120 seconds. I'm having trouble with IMAP IDLE pushing e-mails because the connections timeout so quickly (before any stay alive can be sent). A connection to the e-mail server gets opened on 143 (Videotron) or 993 (encrypted - google, e.g.), and I see the connection on the Internet Sessions page, the timeout starts at 120. When it hits 0, the connection is no longer displayed (it is not renewed), and the IMAP IDLE ****s out because the server can't find the client (i.e. the connection has been closed). But it's not just on those ports or servers. ALL of my TCP sessions begin at a mere 120 seconds! Even for a home router, isn't this way too low?
confirm that their DIR-825, on the Internet Sessions page, shows initial timeout values of greater than 120 for a TCP connection? I would love to see a picture of that screen showing higher values. Does it start at 240? Do you ever see a connection start at a timeout of 7800?
I see no way of changing the timeout value. Is it possible to force connections on certain ports to begin at a higher timeout value?

Per PCI & company policy all VPN users have a 12 hour session limit. They will disconnected after 12 hours regardless of use. Is there any way to send a message prior to the 12 hour limit to warn the users that they will be disconnected in x minutes? I'm running SSL VPN on a ASA 5520 ver 8.4(1)

Is there any way to change a setting which causes a user logged in to the web browser interface (or connected via ssh) to have to re-authenticate. Im getting annoyed by being disconnected from the AP and having to re-authenticate.

Our company has installed ACS Version: 5.1.0.44.6 Internal Build ID: B.2347 with patches: 5-1-0-44-5, 5-1-0-44-6. The security policy of our company includes a password change every 3 months. Our programmers had written a script that allows us to do it. When testing revealed that the script does not work. This is due to the fact that it is not possible to enter the mode "acs-config". In determining the reasons it was found that to enter this mode there is a limit on sessions (6 sessions). When the number of connections becomes larger than 6 then the script does not work. The documentation says that the update is not active sessions is set with terminal session-timeout. In this case, the terminal session-timeout 30. But after 30 minutes of the session will remain active. It interferes with our script.

what would be causing my management HTTPS session to a SF200-24 to suddenly timeout? I receive "The session has been timed out. You may log in again" few mins after logging into to switch.Sometime it happens within 45seconds, other times after 3mins, timouts are not consistent. And, i was not idle when it timed-out. My HTTPs idle time-out is set for 10mins.
I had a continuous PING going to managment IP, and it did not drop any pings when session timed-out.Interface stats are also clean. I tried IE, FireFox, Chrome and all are timming out.
I've changed the HTTP default idle-time out from 1 to 10 and my HTTPs stopped timing out. Management Access Authentication is cleary set for HTTPs, and the Idle-timeout for HTTPs was set for 10mins since install. Yet, adjusting the HTTP idle-timeout cleared the issue.

I have an SG300-20 here for testing (firmware: 1.1.2.0, boot version: 1.0.0.4, language version: 1.1.1.6 English). Everything seems to work on it, except, that if I choose Radius authentication by mac address only, then the switch does not honor the Idle-Timeout and Session-Timeout attributes from the Radius server (freeradius).
The setup is the following: I have a no name access point plugged in to switch port gi1. The port gi1 is set up for Radius authentication by mac address only. The access point itself is authenticated, no problem with that. If I connect through the access point by (say) a mobile phone, it is authenticated, no problem. The radius server does send the Idle-Timeout and Session-Timeout attributes, I checked it by running "freeradius -X", both are set to 30 seconds. Then I turn off the wireless card in my mobile phone and check the dot1x users by "show dot1x users". My mobile phone's mac address remains there for 5-10 minutes, so the Idle-Timeout and Session-Timeout does not work.
Another way I could resolv this problem is by explicitely asking the switch to reauthenticate the user. Unfortunately there is no CLI command to do just that, I can do however a reauthentication on a port using "dot1x re-authenticate gi1" (for example). But it does not work as it is expected: the switch uses the stored mac-address to reauthenticate the user, so nothing changes on the port (unless something changes in the radius server). I think it should work like the following: remove the authenticated user from the port, and whenever that mac address makes some network traffic, then reauthenticate as if it were a completely new connection. BTW: it would work for me also if I could just remove an authenticated user from a port, but I did not find a command to do that.
As a last resort I can simply shutdown the port, bring it up again ("shutdown" and "no shutdown" in the interface config), then all users are removed from the port and they all mush reauthenticate. But it causes a network outage for a couple of seconds for all users on that port, on a busy access point it is quite disturbing, and it is not an elegant way to do this.
So my actual question is: is there a way to remove an authenticated user either automatically (Idle-Timeout and Session-Timeout) or manually from this switch?
I enclose the relevant part of the running config.
interface range gi1-2
dot1x host-mode multi-sessions
exit
vlan database
vlan 2-4
exit

Just recently we replaced our HQ Cisco-Pix with Cisco-ASA 5510. where we have many branches connecting to our HQ through site-to-site vpn. Since putting this new ASA5510 at HQ , while we are getting a Remote-Desktop session into our branches clients, and at the time when even a single TIMEOUT occurs on the vpn-link so the remote-desktop session gets completely lost. then we have to re-connect the session.This issue happens as i said above when a single timeout occurs on the vpn link. What is the issue with the ASA5510. because with pix we didn't have this issue, remote-desktops were never getting lost / reset with single timeout

When a client connecting to a specific AP (example AP01), after every 1800 sec uptime it will reconnect and join other unit AP (example AP02)Both AP physically installed distance is around 6 meters from each other. I conduct the testing where i get myself sitting in middle between these two APs.
01. If i disable settsion timeout this feature, or setting the seconds become higher value, what's the performance and security impact? Is it recomend to change the default 1800 seconds session timeout?
02. Is there anyway i can tweak on WLC controller to prevent the client after session timeout then associate with another AP. This will lead major performance impact as the client woudl possibility connect to the weak signal AP and effect on the performance.
These are the details for reference:Client detail
- Dell DW1520 wireless-N WLAN card, with firmware version 5.100.235.12
- CCX version 4 supported
- Layer 2 security is WPA2 personal with PSK.

I have a customer with two WLC 5508's running 7.0.116.0. When I look at the RF Grouping I see both controllers in the 802.11b/g/n section (802.11b>RRM>RF Grouping). However, when I check the 802.11a/n RF Grouping, I only see one controller.Both are in Group Mode = Auto.
I also made sure they had the same NDP settings, and they are both in Transparent mode.

When performing an audit from NCS Prime 1.3 on our 5508 controllers (500 lic) we are getting mismatch messages from many of our 3602i AP's that say the following...
(Type)Configuration Name Audit Status Attribute Prime Infrastructure Value Controller Value
(AP APname, Interface) 802.11a/n Mismatch Spectrum Intelligence true false
These AP's are not configured as Spectrum Intelligence on the controllers, rather as local. It seems that NCS believes that they are supposed to be SI. We have refreshed the config from controller many times but this does not change. The 5508's run v.7.2.111.3 Is there a change I can make on NCS or otherwise to make this mismatch go away? Is this a bug? It is not causing any problems (that we can see) but as most would rather not have these mismatches.

I have several devices on the same subnet and with similar configuration. All of them were entered manually on the ACS server and are configured to authenticate using TACACS+. Some of the devices can authenticate ok, but other will timeout. I did a tcpdump on the firewall port and can see the device sending the SYN to the ACS server but the server sends no reply to the device.

I have an ASA 5520 and I am having trouble getting the AnyConnect VPN authentication timeout feature to work properly. I thought I did have it working a couple of months ago, but right now it is not giving me more than the default 12 seconds. I have tried intervals of anywhere from 25 seconds up to 120. I am currently runnign version 6.4 on the ASA and AnyConnect 2.5.3055.

picking up on old thread, but same issue: authentification failed because of a timeout
*previously*! i was able to auto connect fine on this home network via wifi.the line and box recently changed, same provider, and now i'm the only one who can't connect.the SSID changed, but i've done all the usual routines, deleting and re-adding manually, etc. but nothing so far...
i *don't* think this is a case of changing gear, but i don't know enough about internet/connection/configuration to fix this. yet!
NB: when i perform the reset on the box as instructed, using the provider's setup software - i am not the account holder - for the wifi, it shows connected very briefly in the animation, and then goes off again; this is the authentification/verification failing, i conclude.
so: with what is said above, i'm wondering if my antivir is to blame, or the windows firewall settings.or malwarebytes.i'm going to study the info i've got off my system, and looking at the router via the http routine, offline, as i now have to get off the internet(...); i'll get the infos together so i can post something useful.

I am using ISE 1.1.3.124.My first question:I want to know the relation between the attribute "WasMachineAuthenticated" and the MAR (MAchine access restriction in advanced setting for AD).Is-it the same or not ?Once you time out, you need to do machine auth again. What is the timer ?Using the attribute "WasMachineAuthenticated", is-it the same timer that you configure in MAR ? In a distributed environnement, is the information about machine previously authenticated replicated to all policy node ?Because, if a swicth has 2 radius-server, we are not sure that it will point everytime to the same server.

[Env on my lab investigation]
supplicant - W7 with cert
authenticator - Catalyst 2960 with IOS 15.0(1)SE2 /newest/
authentication server 2x - W2008/NPS like a RADIUS server
The problem is the end station that are still connected to the supplicant port /use a EAP-TLS/ after the reboot supplicant! All of them will be put into the Guest VLAN instead of static VLAN 34!
[The question]
What is wrong and how to configure/tune and what authenticator or authentication server to prevent after the reboot to observe a authentication timeouts? Of course the supplicant after 20 minutes /next EAPOL start farmet put into VLAN 34.

I am seeing the following behavior when computers move from one switch to another with dot1x ONLY when there is a 'stupid' switch in between.
computer -------- 'stupid' switch ------- 2960
dot1x is working fine but when the computer is disconnected, the port still shows the authentication session id so when the computer connects to another port or switch, authentication succeeds but traffic doesn't pass. While I'm almost certain that the culprit is the 'stupid' switch that doesn't clear the session id, I have already tried another one and the problem remains so I'm actually just asking for a confirmation that all these 'stupid' switches present this behavior and if there is a workaround in this case.

I am quite new to wireless side and had a small Q regarding watching debug output while i am ssh to the WLC? I tried the other day and did not see any messages, now this could be for the reason that nothing triggered or perhaps it needs something like terminal monitor?? i couldnt find any such command. my WLC is 5508 running 7.3 version.

I have a user authentication issue with our WLAN deployment. My issue relates to the guest access WLAN. First a brief descrition of our setup. We have a local WLC in the branch office (5508) with two SSIDs configured, CorpNet for the internal network and GuestNet of external guest access. We also have a WLC (5508) in the DMZ to provide the guest access. We are using Cisco ISE server to authenticate guest users via a web portal.
The authentication process works as it should. An external client gets an IP in the DMZ and is redirected to the web portal to authenticate their account. When they do they are able to access and browse the internet. No problems. My issue is that if we disable their account (ie suspend or delete it) in ISE it does not seem to terminate the users session and they can continue to have internet access. What I would like to happen is that when the account is disabled in ISE then the associated device's access to the internet is removed.

I'm on WLC 5508 . It doesn't matter if passive client feature is turned on or turned off , when you try to increase "User Idle Timeout" you can see this message:
In our network, a lot of clients gets deauthenticated. I thought it would be useful to enable "Passive-client" feature, or increase "user idle timeout" , but how these works with each other?

The behavior of some mobile devices ( as Iphone , Itouch, not Blackberry, not labtops ) with WL Controller (5508) is that, when the client doesn't use it, it disconnects after 480 sec.
The idle timeout configured is 900 sec.
Why the behavior is different in this type of devices? Increase the idle timeout is a solution?

I am running a guest wireless network on a Cisco 5508 WLC with 6.0.202.0 code. My syslog is filling up with the following error message:
WLC: *May 15 12:32:59.244: %AAA-3-VALIDATE_GUEST_SESSION_FAILED: file_db.c:3968 Guest user session validation failed for guest_user10. Index provided is out of range..
The user that is assigned to the guest_user10 account works fine and has no idea this error is occurring.
This error message is occuring exactly every 15 minutes 24x7.
I believe I have a rogue user who has setup a device to try and login to the guest network automatically, every 15 minutes with the guest_user10 credentials. I need to track this device down. I need a way to find either the MAC or IP address of the device that is causing this error message. I have tried turning on AAA debugging on the controller but I dont get anything more than the above error. I have also tried using WCS to look at the client history but it only show the normal activity.
