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?

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.

Cisco Wireless :: 3502 LAP Can't Discover WLC Using DNS

Feb 8, 2013

i have 2504 controller with software and some 3502 APs. I also using 5 APs now and few days ago I bought some additional 3502 APs and I can't get them connected to the controller. My company admins decided to using DNS controller discovery instead of using DHCP option 43. I'm connecting APs to access ports of Linksys switches and APs not in the same subnet as ap-manager interface of controller. AP succesfully get IP and DNS from DHCP and could ping cisco-capwap-controller. However, I have such messages.

Cisco Wireless :: 3502 Not Joining WLC?

May 12, 2012

There are a total of 25 Cisco 3502 APs installed.  24 APs were discovered except for 1 AP.  I run SH CDP NE on the switch and the AP was discovered by the switch but it does not have an IP address.  On the output of the SH CDP NE DE, I noticed that on the AP that is not joining, the Platform is "cisco AIR-SAP3502E-E-K9" while the APs that joined the WLC, the Platform is "cisco AIR-CAP3502E-E-K9".  The software versions are also different but this could be because the WLC already upgraded the IOS when the APs joined.Why is the Platform "SAP3502E" for the AP that did not join.

Cisco Wireless :: 3502 - AP Authentication Via ACS

Apr 2, 2012

Just a basic question regarding MAC based authentication of AP with ACS. The scenario is - If I have a ACS installed and I want all my Cisco 3502 APs to be authenticated on MAC basis via ACS. I know that AP mac is used as a username and password at ACS so that whenever we plugin the new AP in the network, it gets authenticated via ACS first and if the AP is authorized to be used in network then only it gets the IP address from DHCP.
My question is - What will happen, if the AP is connected in local mode on a remote location and the WLC, ACS & DHCP are in Data center. The traffic coming from remote location will pass through the Remote-site router and during that pass, it will remove the source mac address of AP and put the router interface MAC address as source, so how will the ACS authenticate the AP in that case.
When working in a LAN I know its possible, but how will it work over the WAN.

Cisco Wireless :: CDP On Access Points 3502 Aps

Mar 15, 2012

Using WISM with 7.0.220 and 1240 and 3502 APs. Just found that some of our 3502 AP didn't enbale their clean air and CDP when installed. This only happened on a few new APs.  But the area these APs where we seem to have had a few problems with PCs. The only PCs effected where Computer On Wheels (COWs), Dell 780 Desktop with a Cisco Wireless Card.

Using an interl wireless card and others in thes areas worked.Once I enabled the CDP and Clean Air, the COWs worked.My question is with the APs not having CDP enabled, could this affect the cisco wirelss card in the COWs?
