AAA/Identity/Nac :: Primary ACS 5.2 Lost Connection?
Apr 9, 2012
I have a 802.1x solution with two redundant ACS 5.2. Network A configuration use like Primary ACS-SJM and ACS-GLX like a secondary for network B configuration use like Primary ACS-GLX and ACS-SJM like a secondary. My solution was working fine about one year ago. but one week ago isn´t working fine. The problem my ACS-SJM lost connectión and user can´t authenticated when the user trye to connect to ACS-GLX either can´t connect. I have to shutdown the ACS-SJM that way can authenticate to the ACS-GLX. I check the log and I didn´t find anything I check the switch.. too where the ACS is connected. but didn´t find anything too.
both ACS have the following IOS version:
ACS 5.2.0.26.4

We have recently upgraded acs 5.1 to 5.3 ( normal upgrade process), all secondary (ACS-B) was deregistered from primary (ACS-A , used as configuration server and log collector) and updated successfully. But while upgrading primary acs server was rebooted manually. But later primary server was re upgraded successfully to 5.3.
Just to ensure database is not lost on primary acs (ACS-A) , primary acs was registered to one of the secondary acs (ACS-B). Initially ACS-A registered with ACS-B, both ACS was showing proper role now. ACS-A ( secondary ) and ACS-B (primary). But on New primary ACS (ACS-B) is showing new secondary (ACS-A) offline and replication pending. Whereas on Secondary ACS-B its shows primary ACS-A online and updated. But ACS replication id is gradually incrementing. ACS system is in this system for last 2 day, But not sure if there is real replication happening at backend? How long it take place to replicate completely? and how to check / verify status of upgrade?

Today I ran a failover test between our primary and secondary ACS systems (ran 'acs stop' on the primary) and in the process decided to promote the secondary while I had the primary down. All was fine until I brought the primary back up and tried to re-register the secondary to it. I get the following error message: I went into System Administration >Operations >Distributed System Management on each and it showed the other device as deregestered, tried to promote from there but it failed too, so I deleted them and tried to register the secondary again. After that didn't work I tried rebooting both but that didn't work either. I know the user/pass I'm using is good and I've tried using both the IP address and the hostname.

When attempting to register an ACS instance to a primary (via System Administration -> Operations -> Local Operations -> Deployment Operations), I receive the following error as a popup in my browser:
"This System Failure occurred: /opt/CSCOacs/db/acs.crt (No such file or directory). Your changes have not been saved.Click OK to return to the list page."
I had 2 ACS 1120 appliances clustered, 1 suffered a hardware failure about a year ago so I replaced it with a VM. That one is now the primary. I'm now wanting to replace the secondary instance (the remaining 1120 appliance) with a VM as well. I removed the current appliance from the network, installed the VM using the same IP address, and attempted to register. It failed as per the above error. After trying this a number of times, I then decided to return the 1120 appliance to secondary status and attempted to register it with the same results as above.

IP address of Primary had to be changed, to respond to a hardware failure of TACACS server with IP in many device configs.
Now the Secondary fails to respond to repeated "Deregister from Primary" requests, even after reload - apparently because it cannot reach the Primary at its old IP address.
Requesting Deregister in GUI generates pop-up that says, "This operation will deregister this ACS Instance from the Primary Instance. Management applications on this ACS instance will be restarted and you will be required to login again. After performing this operation

ACS 4.2 and remote agent was working properly two months before. But in past two months we are facing weird issue in RA server.For Somedays we are missing logs from both ACS and RA server. Once we notice this we use to restart the services in ACS to give workaround. But due to this we loose our daily logs intermittently and facing risk in without having logs.This is not like communication between ACS and RA is not at all happening. It happens properly for a week or month, but again it is going bad without any config change. CSAgent.ini file is properly configured.Full version is 4.2.1.15 and patch is 10 in acs and ra.ACS and Remote Agent Major and Patch version are same.

We are running an FWSM on a 6509 with a SUP720. Firmware 3.2(18), in MultiContext Routed Mode, with shared MSFC.Everything runs fine on this baby most of them time, however occasionally without warning and with no specific pattern the Primary node will fail (as in completely stop responding) and the secondary will takover as active. Two get the primary up agian, I reset the hw-module and then no failover active on the secondary to return the primary as active. However, after this event, I start to experience strange issues with connectivity. Certain TCP src dst combinations will just not work.

I'm not working on a computer now. This is just a question of curiosity since I am still learning networking. I did a reinstall for someone. Once they brought their computer back home their Verizon DSL connection was not working. He could not Ping Google.com.

I had lost power to my apartment and when everything came back on everything was working as normal...until about an hour later when my internet connection was sporadic at best. I called the ISP and they confirmed that the modem is fine. My other computers can connect to it via ethernet cable and wifi so it doesn't appear to be the router.
When I try to ping anything it seems to time out randomly.. (ran "ping Yahoo! -t1" and let it go for a while..times out every 10 requests or so).
I swapped out the ethernet cable but the LEDs on the NIC are Orange(Amber) for both cables. The wifi on the computer works fine. I reinstalled the driver for the NIC.

I have a router with a motorola cable modem connected to my linksys router. In this network I have a windows XP computer wirelessly connected to the router and a networked disk drive wired to the router through a netgear switch.I am trying to move a lot of files from the XP computer to the networked drive.Everything works great as it will move files for as long as everything is up and running. As soon as I attempt to change the status of the modem from on-line to off-line with the push button on top of the modem, my XP computer loses connection to the networked drive.Why is this happening? I would think the xp computer and network drive are below the modem inside the network so losing the internet connection from the modem should only affect the internet connection

Yesterday after downloading something my internet disconnected from my desktop. However, the internet works fine on any other computer in the house. I'm assuming it's some sort of virus or something...I ran McAfee and it found nothing. When I tried connecting yesterday, it gave me all kinds of different reasons why it wasn't connecting when I diagnosed it. Now however, when I try to connect to it, it says the network key is incorrect, which it isn't.

I was trying to browse the internet earlier, and I randomly just lost my internet connection. My homepage loaded up just fine, but then I tried to go to another site. It was taking a while to load. After about a minute a page finally came up that said "Server not found" (I use firefox). I can't get on any websites now and I can't get internet on any of my wireless devices either. When I right clicked my network icon on the toolbar and clicked on diagnose and repair it said "There may be a problem with the DNS. Windows attempted to find the well known host www.microsoft.com using dns. The server responded that the name was unknown." I have Windows Vista. Now I have no idea what I could have done. I didn't do anything out of the normal, just tried to go to a website that I frequently visit with no problems and this happened. This is what I get when I type ipconfig/all in cmd prompt. [code]

recently I have been using my laptop downstairs where the router is in the same room, and now, when I attempt to connect to the network in my bedroom it connects for maybe a few seconds and indicates an average connection and I can also see other available networks before suddenly all connectivity is lost, I can't even see other available networks. Previously I would be able to get strong signal in my bedroom and I was able to use the internet without any fault.I have tested a family member's laptop in my bedroom, and theirs seems to be working just fine in my room. I can only use my laptop downstairs now and I need to know if this is a fault with my laptop's network adapter or if it's a problem with connection between my laptop and the router.

I dont have an internet connection through my computer. This one tells me error 106. I have 3 computers hooked through the same router. So, I know I have internet, as I am writing this now. But for some reason, that computer is now telling me I lost the internet connection. I have tried unplugging everything, restarting the computer, and nothing has worked. I dont know how to get the internet back on that computer.

My wife and I both have Win XP laptops. For some reason, one day we both lost our wireless connection. However, my wife's machine later was able to reconnect - mine wasn't. My machine sees the wireless network, sends the key, and tries to acquire the ip from the router. That's where it gets stuck. The ip address never gets updated.

so I work with a debt consolidating company. We have about 300+ users, and som of the issues I get are network issues from random users. The issue is that there is a lost in connection and they are completely disconnected from the network. I look at the port number labeled at their cubicle and check the switch they are connected too and this is what I see on the switch. Which by the way is a dell PowerConnect 3548 switch.URL
After removing from those ports and placing the patch cable into another port it works normally. But after a few days this issue returns only to find it with a different user.

I have the netgear wndr4500 setup on my home theater shelves which are located in the corner of the room. When using my ASus G74sx with the Atheros 9002 wifi I consistently get disconnected. The wifi connection is lost and needs to be re-established.
Interestingly, when I am using the laptop downstairs the disconnects never happen. I have pored over my router's settings, updated to the latest firmware, as well as installed the latest drivers on the laptop. I also tried setting the router to short preamble and changing the channels to 11and automatic.
