All of a sudden my cisco anyconnect will not work.  It connects but I cannot connect to any shared drives or ping anything on the host computer.  Any ideas?

There is a way to configure vpn anyconnect logging to track one particular username. Once the user logs in to VPN, the ASA will email the log to email address. I used to knew the website that assisted with this config and I can no longer find it. Does anyone know the syntax for this?
Dear wizards, my router was hang this afternoon. Internet for email system was interrupted for about 20 mins. we could not telnet or connect to it via console port, and had to reset the router to bring it back.

so how can we know what happened? where can we find the logs? was it a signal of DDoS attack? and if so, how can we mitigate it?
I will have a chance of interview for the subject job position.

Can you share with me what I should look up and prepare before the interview?
I have a Cisco 1811 that won't boot due to a memory issue.  It has a 64MB compactflash card in it.  Does that card have the running config?  I don't believe I have a backup of the config anywhere.
We currently have a WLC 5508 with a 2nd for High Availability. It is managing the following models:
We are considering adding the following models:

The questions are:
1. What firmware version do we need to upgrade to, to handle the proposed new models?
2. Which, if any, of the existing models will not be compatible with the new firmware version?
3. From the point of view of licensing, we don't need to have separate licenses for the HA, do we?

Thank you

2.      The pc’s are located in an office on the east coast New York, and the AS400 is in another office in the Florida. In the Middle is a cross connection router and firewall located in North Carolina.

All Users in the Florida office using this application experience the following everyday and at least once day.

The user or users in the Gui application first receives a small swirling circle while in a transaction like the program is thinking !, and then receives this message from the program “ this program has terminated”.  This happens everyday.

I've been having some network issues, where for a moment or so, the internet and just network access stops working for almost everyone.

I started digging in the logs on some of the switches, and I came across this at about the exact time when this occurred.
What exactly does this mean?

      2486: Sep 21 19:57:57.069: %SPANTREE-2-UNBLOCK_CONSIST_PORT: Unblocking GigabitEthernet1/0/1 on VLAN0001. Port consistency restored.

How can I further troubleshoot my network issue?
Hi All,

I'm installing the Cisco Anyconnect software to our ISR 4431 and it's asking me to setup RSA keys and self signed certificate but it's asking me to overwrite the existing one ? We have a site to site VPN setup that i think these keys were for so firstly if i DO overwrite the original one's then will this cause an issue with the site to site VPN or can i use the existing RSA keys etc with Anyconnect (and if so how)
Hope this makes sense.
So, here is my scenario

Currently with network set as VLAN200 on a switch, my router is

Got a cisco 2960 switch as, and set with default GW

However, I need to set a new vlan for a vpn (mikrotik)

Mikrotik ip is

Ive created a VLAN400, as and indicated the ip helper as the mikrotik. After assigning ports to that VLAN, it doesnt acquire IP, neither reach the GW (if I assign static IP to the computer). From the switch, if I try to ping the mikrotik ip, it does not respond (if I connect a computer directly on the mikrotik, I do get an IP, I can access it and even access the VPN services without problems)

Am I missing something?

thank you
I have a Cisco 4506 chassis with (4) 48 port switch modules in it.  It is on a known good UPS, has redundant power supplies and everything.  About six weeks ago, the switch restarted itself for no known reason.  I couldn't find anything out of the ordinary ... it just came back online by the time I got to the switch room.

Today, It happened right at 3:00pm.  Reports that I got had some people losing power to the Cisco phones (PoE) and others claimed the phone didn't lose power but the display said ethernet connection lost.  The phones losing power were on switch module 3.

I went into the IOS and did a sh hardware and got this:

My question is, what else can I do from a troubleshooting standpoint?  Is it possible that just switch module 3 in the chassis lost power and the rest of the modules remained online?  I am having to accept end-user answers that some Cisco PoE phones lost power and some did not.…

I am trying to fix the issue with ASA firewalls. I have L2L VPN between two ASAs with IP Sec tunnel with IKEv2. The tunnel is working fine for one pair of source IP and dest.IP address.

However, I have another pair of IPs (two servers between the remote LANs) which are included and permitted in the same access-list and crypto map as the working pair of IPs. But they are not able to communicate.

They are also permitted on the access-list which is applied on the inside interface from the LAN.

I can see the Built TCP connection in the ASA real-time log for the working pair of servers, but absolutely no information in the log for the another pair.

In the LAN we have another ASA directly connected which is showing "SYN timeout" after 30 seconds.

It is very strange, because the access-lists for the mentioned pairs of source and destination IPs have the same configuration and are applied the same way, but security association is bulit only for the first one.

I even see hit counts in the access-list permit statements for both communications.

Is it possible, that the issue can be on the remote end of the tunnel (the 3rd ASA on the way for the packet towards the remote LAN)? I don't have the access to the 3rd ASA.

Please help,
I had this question after viewing Lot of packet drops in a Wireless LAN.

My topology is simple and straigth forward

Why cant I configure ip flow top talkers on my IOS? Is it the version the issue maybe?

hello experts
i have some old Cisco autonomous AP, such as Cisco 1250, 1260, 2602 serials, looks like it is not support to configure captive portal authentication, although i have upgrade them to the last software version, because i need setup a wireless network for guest users.
please kindly let me know it is possible or not.

I can see them all from the dashboard but really want them in excel or CSV, all the reporting seems very heavily wifi based, I am only interested in the actual port configs.
