Cisco Switches :: SG300-20 - Radius Idle And Session Timeout Does Not Work
Jan 25, 2012
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.
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 am using the CISCO SG300-28 with firmware version 1.0.0.27. I enabled RADIUS authentication and accounting. Authentication is working but there are no accounting requests/replys (Accounting on, accounting off, accoun ting start, accounting stop) when running RADIUS in debug mode. I also did a packetcapture and there are no accounting packets.
So i updated the firmware image up to version 1.1.2.0. When I now want to configure accounting in RADIUS settings then there isn't any option to set an accounting port.
Ich checked the data sheet of the switch and it says that accounting is supported:
=============================================== 802.1X: RADIUS authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple host mode and single/multiple sessions [URL] ===============================================
I did a second packet capture with the new firmware image and there are still no accounting packets.
The RADIUS server is configured correct for accounting because when using another NAS like a WLAN-AP with DD-WRT accounting is workings. It is working with pfsense Captive Portal (an open source firewall and routing solution with a hotspot portal).
I have an SG300 authenticating telnet login to a RADIUS server. It allows me to log in at Priv level 1. when I try and enter Priv 15 mode, I'm prompted for a password which I don't appear to be able to set anywhere or know.
If I remove RADIUS and go back to Local authentication, telnet logs me in at Priv15 immediately.
I am using several SG300-28 Switches with firmware version 1.1.2.0.I have dynamic VLAN enabled. As RADIUS server I am using free radius 2.1.12.Authentication is only based on the MAC address. (I configured that on the switches)On the switches I created three VLANs. VLAN100 for the authenticated clients, VLAN200 for Management interface and VLAN300 as Guest VLAN. After a wrong authentication the clients should be put into this Guest VLAN immediately (I configured this on the switches). I am using Windows XP and Windows 7 clients in my network. I did not configure any EAP settings because I just wnat to use the MAC address.
In most cases the dynamic VLAN assignment and authentication is working fine. The switch log says that the client is authenticated and the same I can see on free radius log. But in some (rare) cases the client is rejected. The CISCO log says "MAC aa:bb:cc:dd:ee:ff was rejected on port ge17" but when I look at the free radius log then this MAC address was successfully authorized.
The problem is that the client gets an IP address based on the Guest VLAN300 but after that the switch seems to "switch" the VLAN on the port and then the client is authenticated correctly on the right VLAN but the client does not request a new IP on the new VLAN. If I unplug and re-plug the LAN cable in most cases the client get the correct VLAN and the correct IP. This is happening randomly on nearly all my PCs.
Do I have to set some timers higher ? I don't think it is a problem between switch and RADIUS but a problem between communication of the host and the switch.
On the modem page with all the settings Under basic settings For connection it says Always Connected The box underneath says idle timeout 5 (that's in minutes)
I am unable to change that number or even get a cursor to appear in that box (I want to change it to a 0 - my internet connection has been dropping out when going idle). I can't right click or anything. That is using Firefox. When I say dropping out, I mean, the 3 computers on the network become unuseable - nothing works and things don't appear to be connected to the internet even though my green ADSL light stays on like it's connected - it is not.
I tried the same modem page in IE, and that box with the 5 in it is still showing 5, but this time it's just grayed out - again, can't be changed. The firmware updates are all upto date (apparently - according to it's check)
I have ASA 5510 with 8.2.4 and 8.0.x OS and all seem to have common problem of idle TCP connections not timing out. The host to host connections are coming over VPN tunnels. I have default timeouts on all the firewalls. I have tried changing global timeouts and as well as host specific timeouts using MPF but doesn't work at all ! The problem is when TCP connections are sitting idle in conn table for days and when connection limit of 50,000 conns reach the firewall starts behaving unpredictably dropping packets or unresponsive! I need the unused idle connections to timeout which is NOT happening either by changing global values or MPF.
If i set up a pptp vpn between a Cisco rv082 router and a microsoft client,Can i set the client idle timeout someway? or Have a default value pre- configured for this?Because this device support 5 users to connect at the same time. It would be best for me, if the device drop the client if it does not use the tunel.
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 have a CSS 11503 with a basic content rule for TCP 10000 going to a few backend servers. I was looking into the default timeout values for flows and when testing using telnet the flow didn't terminate as expected?
For example, i have no 'timeout multiplier' specified in the config and when i look at the output of 'show flow-timeout default' it tells me the default 16 seconds timeout is in effect for *. With that in mind, i telnet to the content rule vip on TCP 10000 and on the backend server using wireshark i can see the TCP threeway handshake. With no data passing i'd expect the CSS to terminate this flow after 16 seconds.. yet it takes exactly 128 seconds before wireshark shows the RST and the flow is terminated. 128 being 8 times the default 16 second flow timeout.
If i try to force the connection to close early by specifiying 'flow-timeout-multiplier 2' in the content rule, or even a multiplier of 40, it still waits 128 seconds to close the telnet connection.
Not sure where the best place to drop this question. It is a DIR-601 router. I have it configured in the virtual servers list as; internal system ip, public port/private port both 23, protocal tcp with inbound filter, allow all and schedule set to always. I have a second system with a different public port. I can connect to either one but after a short amount of idle time it appears to just drop the connection.
I received an SG300-MP as an RMA replacement for a Linksys SRW2008MP and I can't seem to get the SNTP to work.Previously on other devices I have only had to set the SNTP server name or IP address and that was it. So some of the options of the SG300 are foreign to me.So I first set
Administration > Time Settings > System Time > Main Clock Source (SNTP Servers) [X]
Then I set several SNTP server IP addresses
Administration > Time Settings > SNTP Unicast SNTP Client Unicast [X] Enable > Add Other / 64.147.116.229 (nist1-la.ustiming.org) Other / 24.56.178.140 (wwv.nist.gov) Other / 128.138.141.172 (utcnist2.colorado.edu) Other / 129.6.15.29 (time-b.nist.gov)
Some servers I set "Poll Interval" and some I didn't because I wasn't sure what this does.The status for all servers indicate "Down" with 31.12.1899 0.0.0 for the "Last Response"/I found those IP addresses via [URL] Also the setting
Administration > Time Settings > System Time SNTP Multicast / Anycast
I have disabled, and I don't know what this does either...
Using a sg300-52 switch I created two VLANs that share a port for access to the internet. All original devices added to the VLANs are functioning correctly so I have to beleive the VLANs are set up correctly. I added a new desktop and an old laptop to the VLAN and neither worked. I was able to get the desktop to work by enabling VLAN tagging in the network adapter. The laptop is 5 years old and it does not have any such setting in network adapter. There are 2 other devices that share the same port with the laptop and they both function properly. My conclusion is that the laptop does not support VLAN tagging. Is there someway to configure the switch to account for this?

I've got an SG300-10 connected back to back (trunked) with a Cisco 3560X switch, across a fibre link and am seeing some big inconsistencies in terms of unicast data transferred across the ports between them.
During a night time window of 4am - 6am I run backups which involves a large copy of files, that almost saturates a GigE link - we can see from the 3560X end that the link is running at a bit over 800MBit/sec of throughput, sustained. The duration of this transfer is consistent with the size of the files being transferred (ie just over an hour, and is what I'd expect for a data transfer of about that amount). Back-of-the-envelope calculations indicate that the 3560X is measuring this data throughput correctly.
However on the SG300 end of the link, which is also being polled by the same application (Cacti), I'm observing spikey counts of only around 20MBit/sec during that window. These counters are very obviously incorrect - there's a huge amount more data moving across the port than that. The incorrect calculations are showing on both the trunk port out of the SG300 (uplink) as well as the interface where the NAS is connected in (which is an access port).
Cacti is polling the OID: .1.3.6.1.2.1.2.2.1.16.57 which translates to IF-MIB::ifOutOctets.57 = Counter32.I'm running version 1.3.0.62 but this problem is not new to this release - previous releases and 1.2 based releases also had this problem.
It looks like multicast traffic may be being counted correctly (that's only a suspicion though), however what I am certain of is that there is a very large discrepancy with the unicast traffic counts.Is this OID the correct one to be using for this switch?
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.
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) .
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.
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.

i am configuring a Cisco Secure ACS 1120 appliance running ACS 5.0.0.21 to handle RADIUS request from a Cisco WLC 5508 appliance running version 7.0.116.0.these devices have open communication on all ports - no firewalls or ACL'sthey have successful ping communication The following statements illustrate some but not all the debugging I have done to ensure each device functions as it should in isolation.Using a simple windows RADIUS server (radserv2.exe) instead of the Cisco ACS This works and the WLC gets RADIUS response from my makeshift serverUsing a simple windows EAP client to query the ACS using RADIUS protocol this works and the ACS processes the RADIUS request and sends a responsePlaced a wireshark client on the network to inspect timeout. Wireshark logs the packet from the WLC to the ACS using port 1812 but doesn't see any packet responses from the ACS At the moment I have the WLC accepting the association from the wireless client and sending the RADIUS (PEAP, EAP-FAST or EAP-TLS) request to the ACS, the WLC receives no response and generates a timeout message and disassociates from the client. note this is not a reject or similar message, the ACS simple does not even process the packet. i.e. there is absolutely nothing in the ACS logs to suggest it even received a radius packet from the WLC. In summary the WLC and the ACS successfully function independently but they do not communicate via radius.
Need deployed accounting method to log Anyconnect session details ? Do you do it via a radius server or via logging messages to a syslog server ?
Any appropriate configuration ? I am looking to log successful and unsuccessful authentications as well as session length, log on and log off times.
I've been playing around with Anyconnect authenticating to AD via ACS 5.1 but can't seem to get the accounting details I require. Similarly I have tried to catch appropriate syslog messages but again without much success.
I am having trouble with my Cisco SG300 switch big time. I have two servers with IP addresses 10.17.0.11 and 10.17.0.29 sitting on the same switch which is a Cisco SG300. I initiate a file transfer from 10.17.0.11 to 10.17.0.29. I could see lots of Dup Acks and retransmissions which means something is wrong in the connection. Further, I could see the session initiation a bit bizarre. I could see two SYN packets sent from 10.17.0.11 to 10.17.0.29 and also two SYN ACK packets returned by 10.17.0.29. The switch forms part of a network but since both the servers are sitting on the same switch I suppose the rest of the network doesn't come into play when one server talks to the other.
See also the number of Dup Acks and retransmissions. The two switch ports connecting the servers have speed and duplex set to auto negotiate, flow control is enabled. What could cause this sort of problem?Could it be any setting on the switch or the servers' NICs?Or could it be a bad switch that causes this?
These are our first switches and seems like GUI is lot different than the online. Out intervlan routing is o not working. I am absolutely sure that I setup the switch in L3 mode since it allows me to create mutiple interfaces. I am hoping that this GUI issue is related to interVLAN routing.
Below is the blog I started for InterVlan issue [URL]
This is the link for online simulator and what I see in its IP tab. I know this switch is not SG300. [URL]
This is what I see on our switch.
