I have a L2L IPSEC tunnel between a set of failover pair of two ASA5510's and a single ASA5505. Over time they will loose connectivity through the tunnel. The tunnel itself stays up, but cannot pass any traffic.When looking at the tunnel I always see this on the set of 5510's (marked in bold @ IPSEC ID 3)?

Cisco :: After Connecting VPN Giving Connection Timed Out Error?

Jul 24, 2011

I had been working on our client servers through Cisco VPN using internet datacard. But from past 3 weeks after logging into Cisco VPN using my username/password, when I try to connect to any of the servers, it is giving connection timed out error.

Whereas, my team members across other locations are able to connect to the servers using my VPN username/password.

I thought there might be some issue with my laptop or internet datacard. I got my laptop formatted, even tried out with fresh new laptops & new internet datacards, but the issue remains same.

I have tried using vpn_5.0.06.0160-k9 & vpnclient- to connect but issue did not get resolved.

Internet Is Giving Limited Connection Error

Apr 22, 2013

I am currently on Time Warner Cable 10 mbps packge, and am using their wireless DOCIS3 modem/router. It is connected in my bedroom to the main computer. That computer stays connected. However, throughout the rest of the house (we have a two story townhome) it will drop completely or give limited connection...constantly. Sometimes I can have my laptop next to me and it will go out or give limited connection. The connection speed never drops, it just goes completely to no connection. Not for sure what is going on, if its on my end or time warner. Has been doing this for quite some time, the cable company comes out and changes the modem, but that's it, couple days later, goes back to doing it again.

AAA/Identity/Nac :: 1841 Giving Error In Authentication

May 15, 2013

I have an 1841 that was working fine - I could SSH to it with my Radius login and console into it with local credentials ("Fred").I added another use ("Mike") with priv 15 so the end user could log in locally via console if needed.After that, we can both log in via console, but when we try to enter privileged mode we get "% Error in Authentication", before even entering the   password.I can still log in via Radius SSH with no problems and access privilege mode via SSH.What am I missing so we can have two different users be able to log in locally with different credentials and access privileged mode, and keep my ssh radius working?

Cisco Switching/Routing :: Giving Out Discard Error On 3750E

We're seeing "OutDiscard" error on a LAN switch connected to newly migrated Cisco IP phones. All the other error counters are clean except for the OutDiscard. (please see attached "show int count err" output.) [URL].

According to the link above, the common cause of such discards can be to free up buffer space.(Am I seeing a switch buffer issue?) How to identify/resolve the cause of the OutDiscard.The switch is 3750-E running c3750e-universalk9-mz.122-44.SE6.bin

Cisco Switching/Routing :: Nexus 5596 Giving Error In Connection

Aug 28, 2012

I have 2 datacenters running same equipement (two Nexu 5596 with FEX).I just took a look at the log just to see if everything is ok and I saw that I have the same error message (a lot of times) at both location :
%SYSMGR-FEX100-5-HEARTBEAT_LOSS: Service "satctrl" heartbeat loss 2 ,max 7,I though it was a problem with my peerklink-keepalive connection but I see the word FEX i'm not sure...
Note that at both locations, my Nexus are connected back to back through the management port using transceivers. So it's a copper cable from the first nexus,  going into a transceiver, going to another transceiver in fiber and then back to copper to the other nexus.

Cisco VPN :: 3825 - VPN Client Is Giving Error And Unable To Create Certificate Enrollment Request

Feb 21, 2011

We find ourselves in a difficult situation with the Cisco VPN Client version where it keeps giving us an

"Error 42: Unable to create certificate enrollment request"

When we attempt to use the Online enrollment method to create and enroll a new certificate. There is no additional information in the VPN client logs where we have set 3-High for all logs. In addition, Wire shark does not show any packets sent from the machine running the client to the Cisco 3825 router which runs the Cisco CA.
To create and enroll a certificate we do the following:

1. Click on the Enroll button to show the Certificate Enrollment dialog
2. Select  Online
3. Select <New> for Certificate Authority
4. Enter as CA URL (note, is the IP of the Cisco 3825)
5. Click Next to display the dialog where we can enter certificate details
6. Enter details in all fields except IP Address and Domain
7. Click Enroll which shows a dialog with the Error 42 ... message in it.
If we attempt to create a request by using the File method, all works fine, that is, the client creates a file with the enrollment request. The fact that the client does not send any messages to the Cisco CA leads us to believe that we have a problem on the client machine. However, the client does not write any information in the logs, so it is a bit hard to fix the problem. I can provide additional configuration information if required for both the client and the Cisco CA. Note that we have not modified any client configuration. Basically, we installed the client on a Windows 7 64bit machine and attempted the steps listed above.

Belkin 54G PCI - Limited Connectivity Error

Jan 24, 2011

My desktop is fitted with a Belkin 54G PCI card which I have never had problems with before. My desktop is in the basement and due to poor signal issues another router has been set up in the basement. I had to constantly repair the connection to the previous wireless network but even though the signal is much stonger with the new router and network I am having even more issues with not only having a repair the local only connection issues but also with 'limited connectivity' and the only way to resolve it is to restart my computer.

Getting Error Messages With Limited Or No Connectivity

Jan 20, 2011

Our building used to have a very old server that basically just served as a place for teachers to store files and not much else. We have just changed ISPs and decided that we no longer needed the server at all. I disconnected the server from the network and replaced the old ISP's modem with the new ISP's modem. At first, everything seemed OK. My computer and several other teachers' connected to the Internet with no problem. However, some of the computers in the building could not connect. We get error messages with "limited or no connectivity." Part of me thought that perhaps the connections themselves are bad. However, when I take my laptop to classrooms with trouble connecting - mine connects easily using their cables. If I move their computers to my room, their laptops still won't connect. I have put my computer side-by-side with another one to make sure the settings were the same (auto-detect IP, DNS, etc.) and can't find differences. This problems is affecting our Windows 7, Vista, and XP computers the same.

Acer Aspire One AOA150 ZG5 Netbook - Limited Or No Connectivity Error

Sep 24, 2011

I just got a used Acer AspireOne AOA150 ZG5 Netbook and upon bringing it home, I received a "Limited or No Connectivity" error when attempting to use the internet via wireless. I have another laptop that connects at the same time with no issues. The Netbook DOES work if I hardwire into my home router. I have since taken the Netbook to work and it connects to the wireless there with no issues. So it seems to be an issue specifically with my home router/modem and this Netbook.So far I have flushed my DNS cache, done the Winsock and reset my TCP/IP, removed wireless profiles, and tried the Repair function.None of that has worked. My wireless properties are also set to automatically obtain the IP address.I'm on XP SP3 and it seems like a lot of folks think that it's a SP3 issue, but I don't think so in my case since the wireless is fine in other locations.

Linksys Wireless Router :: E2000 - Local Connectivity Error

Sep 16, 2012

I have gone into the router itself at, changed settings, reset settings, upgraded firmware to 1.0.04, and / or whatever else was posted by other users. I have also changed my settings for my lappy's networking adapter, re-edited my IP, removed / reinstalled network adapter, and / or whatever else I found to try to do. I am frustrated and upset that a wireless problem is giving me so much headache.I am running Vista 32 Home Premium, HP Pavillion dv6700 Notebook, with a Cisco Linksys E2000 Wireless N Router. I have connected a desktop via wireless USB adapter, my android phone, my GF's android phone, her kids iTouch and phones, and when I try to connect via wirelessly to the router, I get local access only with an unidentifiable network, which then limits my access online, (I cannot connect to the internet). It will let me get online via ethernet cable, but not wirelessly. I have bypassed the router and connected directly to the modem without any problems. I have reset the modem and router many times, as well as rebooted my laptop a lot trying to gain some connection. My laptop can connect to other wireless hotspots / access points without any problems.
