Cisco AAA/Identity/Nac :: ACS 5.2 Hangs On Connecting With MS AD At Random Intervals
May 30, 2012
I have a simple ASA, ACS, AD schema for RA VPN authentication. All is working for a few months now, but since the initial deployment we have this connectivty issue regarding ACS and MS AD. At random intervals, 1 month/1 week, the ACS connection status becomes "DISCONNECTED" although the CLI shows that ad client is running. But because of that, no RA VPNs can be authenticated. Clock is not a problem, since it didn't change automatically nor was manually configured prior to the malfunction.

My internet is randomly disconnecting every once in a while. It seems to be at random intervals of 30 minutes to two hours. While it is disconnected my modem lights are still on and it says that I am connected to the internet.I am wired directly to a modem from my computer.

our RV220W router has been experiencing random reboots throughout the day, causing a network outage for our local network for the few minutes it takes for the router to start up again. We've seen it reboot at least 5 today alone (and the time is currently just a little over 1pm).I'm having trouble finding the reason for these reboots in the router's logs, although I find these two lines repeating in the error log:
Mon Jan 28 13:20:52 2013(GMT+0100) [rv220w][System][EVTDSPTCH] umiIoctl (18, UMI_CMD_DB_UPDATE(4)) failed. table=dot11STA row=11
Mon Jan 28 13:20:52 2013(GMT+0100) [rv220w][System][PLATFORM] /pfrm2.0/bin/bwLimitConfig /tmp/system.db 18 dot11STA 11 failed. status=-1
I'm not sure why these messages pop up, since we're not using the bandwidth limiter module of the router (granted, we do use QoS profiles to ensure our own LAN is prioritized over the guest VLAN). I'm also not sure whether this is related to the router reboots.
I also find the following repeated line in the warning log:
Mon Jan 28 12:50:50 2013(GMT+0100) [rv220w][Kernel][KERNEL] ERROR:endChantRecv: protocol PNAC returned !OK
The router is currently running on firmware version 1.0.4.17 (latest official release), since we needed support for hairpin connections (as I found out in a previous thread of mine). I've seen the suggestion of downgrading to a previous firmware version in another thread, which has possibly solved it for the poster in that thread, but as we really need the hairpinning support, I don't know which firmware version is safe enough to downgrade it to, if needed.

I have a WBR-1310 router that for the past few weeks has been giving me 'limited access' issues at psuedo-random intervals. The router functioned perfectly for a long time, I dug it out of storage about 8 months ago, and up until Christmas it was working fine, then both my roommate and I got tablets. Now our router is supporting 6 devices (PS3, 360, lappy, 2 tablets, smartphone) and occasionally more (other peoples phones, roommates laptop once he gets it repaired). However my research online has led me to believe that I should be able to support near unlimited wireless devices on the network (though effectively only around 30). Still, these extra two tablets are the ONLY change to the network that happened immediatly prior to this problem starting.Now I find that when I'm home alone I can go for the whole day with no network issues, but as soon as my roomy gets home and starts to use his devices the network craps out. unplugging the router and modem for 30 seconds fixes the problem temporarily, though the time before it craps out again ranges from hours to minutes.
I CAN plug my lappy into the modem directly when the router is not functioning and still have internet access, so it's definitely the router with the issue.All devices except for the PS3 are using wireless. I've done a hard reset to the router and set it back to factory settings on two occasions, I've changed the SSID and passphrase to get others off the network, I've changed the security type twice, I've tried some suggestions for similiar problems online such as enabling 'gaming mode' on my routers homepage, and setting a custom IP address (I used 10.0.0.1).Over the last 72 hours or so (the problem has existed for a few weeks) I've also received a few messages about my laptop having an IP address conflict; unsure if that is related, but I'm still able to access the internet when I get that message (albeit slower than average) [code] I will update this with another ipconfig the next time my internet dies; which I'm sure will be sometime today.

Wired PC randomly disconnects from network at random intervals each dayoday it has done so 3 times. The only way I have found to get it working again is to reset the router which can be inconvenient. When it disconnects all wireless devices continue to work and I have no issues like this with my wired consolesI switched to using a static IP address, since having an automatic one gave me the same results [i have since switched back to automatic]Be happy for any suggestions on how to sort this. I am using W7 OS and I'm using an Orange router. I don't know if its relevant, but when I go to reset my router I have noticed that the download light on my router is flashing like crazy when my PC has disconnected.

I've been having this problem on my desktop and it's really annoying when i try to play online games that need a constant connection.I have Windows XP and i'm using a wireless connection via a wireless USB adapter. The problem is that the internet is running fine but at random intervals it starts to not send or receive any packets. This will usually cause my to disconnecting during a game causing other players inconvenience. After I d/c the internet will usually take 5-30 seconds to start sending and receiving packets again and regain connection.

Router is connected to my ISP with the option Keep alive and redial value of 20 seconds (the lowest i can set). There are two distinct problems: Router drops connections at random intervals. It can happen once a day or several times a day. It always happens overnight (so every morning it isn't connected). This doesn't seem to be related to ISP as direct connection to computer is stable.The Keep alive option isn't working. When it drops connection it isn't trying to re-eastablish it for at least 2 minutes (the longest i have waited so far, 6 times the redial value configured). Producing external traffic (e.g. constant pinging of some host by IP address, refreshing some web page) doesn't work. When i log on to admin console (browser based) simply clicking connect button brings connection back online. I've even been looking at status page constantly refreshing to see if it ever made a single attempt and it appears it didn't.I did my "homework" before posting (upgraded FW to 2.0.02 build 3, finetuned MTU).

Two years ago, a lightning strike fried my ADSL router and LAN port on the motherboard (ASUS A7V8X-X) of my now very old system. After that, I bought a Wi-Fi USB adapter (AirLive WL1600-USB) and disabled the fried LAN port. Since that moment, my computer kept freezing totally randomly for the past two years - it didn't matter whether I run a dozen of programs or simply leave the system alone. First I didn't know what's causing those freezes, until a week ago. You see, we were forced to cancel our ADSL account for four months, so I haven't used that Wi-Fi adapter for the entire summer (I disconnected it and uninstalled its drivers). During that time - not a single freeze for four months, no matter how great the system load or temperature. A couple of weeks ago, we activated our ADSL account again, so I plugged the Wi-Fi adapter in and installed its drivers - and the freezes started again.

Network running about 60 computers, most of which are running windows 7 professional. Some are on a domain, some are not.At (seemingly) random times, some computer on the network will lose the ability to browse websites (including the web interfaces of networked devices). I can't identify what circumstances cause this to occur. I only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.

We are running WLAN using WPA2-enterprise with AES & IAS server.Mostly we are using AP's 1131 and Cisco WLC 4400.I added on a new location 2 AP 1142G and since the installation I got 3-4 clients having regular disconnections.Basically they are connected immediately to the infrastructure but after a certain amount of time the Win7 icon is having this yellow exclamation sign, and we can see that the connectivity is gone (however the IP settings seems to be still in place, but ping or network browsing is not possible).Stopping the WLAN and starting it again solve immediately the issue (via software or via the notebook switch). Normally the problem doesn't resolve by itself.
I was working beside the laptop having the problem with (my own laptop) during the person got 3 disconnections, mine was running like a charm.We have 85% of the people there working errors free.Checked the 1142 AP for any logs or errors, interfaces status etc...Checked the switches behind, interfaces seems running smoothlyChecked IAS / WLC / WCS for any logs that can indicate an issueCompared WLAN adapter settings of the faulty laptop with mine, discovered some differences and adapted it.Compare the WLAN SSID config in Win7 with mine and adapted the slighty differences found.Used WCS troubleshooting client tool.What I will do again :Verify if the persons having the issue have the same laptop modelVerify settings in the BIOS Verify WLAN adapter driver versionVerify BIOS versionUse WCS troubleshooting client tool on my own laptop at this place.

I have the Qwest/Actiontec Q1000 modem/router. I go to the ip address using my web-browser and open up advanced configurations -> access scheduler. I select a computer (and it automatically adds the MAC address) and then the days/times I want the internet to be accessible. However, when I click "add" (to add my internet allowance to the scheduler list) it just says 12:00 to 0:00, which is essentially permanently blocking the internet for that computer.

Why does the sx300 series only displays ping and traceroute results in 20ms intervals (see below)? The example in the CLI manual shows "regular" results. These 20ms intervals are not useful for troubleshooting. This is version 1.1.0.73 on an sf300-24. [code]

I currently have a Cisco ACS 3415 appliance with 5.4. Coming from the ACS 4.2 world, I'm have a bit of a struggle creating the following and I was hoping if I could be shown clear steps I can duplicate the rest.
I want to creat a group ie: AIRTEMP with access time from 7:00am to 5:00pm and add 2 users to the group.
Users access our site using a vpn client connecting to a ASA5550. The ASA and the ACS already communicate with each other.
The ACS 5.4 user guide has me bouncing all over different page.

Any issues on Cisco ISR / ISR G2 routers running 15.x code while doing NAT for large quantities of users (3000+) involving lock ups? This seems to be an ongoing issue for a customer. The symtom is present on 2811, 2911 and a 3945. The 3945 never spikes over 10% processor or memory utilization, yet still has these issues. The routers have been tested running 15.0(1)M5, 15.0(1)M7 and 15.1(4)M4 which all showed simular results. Other router side services are running such as NetFlow v9 to two destinations. Another interesting symtom, doing a "show ip nat translations" command will crash the router if executed at its peak usage period. NAT is to a single IP (sourced from outside interface), not a pool.

Few months back I had purchased this Router. But I did not use it till last week. Since the time I have installed it, it does freeze often (between 5 to 30 hours).
I can connect to devices within the subnet, but not elswhere. I have to remove the power and plug it back for it to respond. I have updated the firmware to the latest one that was on the Cisco site.

I am running a 1921 with 15.0(1)M4 on it. The router has a /29 public block assigned to it so I have a public IP for my router's GW, a public IP for the WAN interface on the router, a public IP for PAT and the three remaining public IPs I use them as static NATs for internal hosts.
My problem is that the particular static NAT assigned to static host1 seems to "hang" every few days. You can ping the public IP and it will respond but the rest of the services of the host like www, ftp and telnet do not respond. If I reboot the router then all services of host1 will work again. Note that all other static IPs including the ones used for static host2, host3 and PAT will always work and never give any problems.
I am fairly certain that this is not a config problem so I have shuffled around the public-to-private NAT entries. Basically whatever public IP I assign to this host1 will at some point hang. The host2, host3 and PAT always work and never hang no matter what public IP I issue to them.
So since it isn't a problem with the public IP I changed the private IP of host1 and still it hung!! This host1 happens to be a linux box. host2 and host3 are a Windows server and a different flavor linux if that make some kind of difference.

As i'm facing the issue with Cisco CSC module installed on ASA 5510, It hangs up and doesnt work sometime, so it is bypassing all the traffic without inspection through CSC module. After restarting ASA 5510 box, it works fine as it used to work. Now, My question is how can i refresh the module again without interrupting the ASA box/ and how can i avoid this problem forever? Because i cant interrupt the daily work due to this module problem by restarting the box again and again.

My PC boots fine (via SSD) but as soon as it passes the login screen and brings me to the desktop, the network connection icon has a circle going around it for about 30 seconds. Except the circle isnt moving, or rotating as if it's frozen and when i click on it to go into the network and sharing settings, it hangs. While this happens i can access anything else fine except internet based apps. Once it connects, everything is normal.
I use a Netgear Power line Adapter and have been for years, and have never had a problem with it. I am running Windows 7 Enterprise 64 bit.

Cli/ssh is fine, but the ASDM on Win8 64 bit seems to constantly have issues. Sometimes it works fine, other times it hangs at "Software update completed" or at a weird percentage and then never opens. I have noticed that disabling my Trend Micro realtime a/v scanner aids, but still doesn't completely fix the issue every time. speed it up or at least make it work every time?

My team has installed a 1905 series router at one of our offices. It has been connected through lease line to our servers at our head quarters. When we start internet access it slows down and subsequently it hangs. When we log into the router and start verifying its configuration it hangs after some time. We have replaced the router but the other router is also behaving in the same way. the possible areas and settings I should look into including lease line connectivity.

the inside interface on our primary ASA seemed to "hang". It dropped all the packets it received. Because the interface didnt go down, failover didn't happen. Device's info;
-Cisco Adaptive Security Appliance Software Version 8.2(3)
-Device Manager Version 6.3(3)
-Hardware: ASA5550, 4096 MB RAM, CPU Pentium 4 3000 MHz
-Internal ATA Compact Flash, 256MB
-BIOS Flash Firmware Hub @ 0xffe00000, 1024KB
I attached a capture picture shows that traffic didnt go to the roof when the issue happened. Why the interface would "freeze" randomly?
