Cisco VPN :: ACS 5.1 Anyconnect Session Accounting Via Radius Or Syslog
Feb 22, 2013
Need deployed accounting method to log Anyconnect session details ? Do you do it via a radius server or via logging messages to a syslog server ?
Any appropriate configuration ? I am looking to log successful and unsuccessful authentications as well as session length, log on and log off times.
I've been playing around with Anyconnect authenticating to AD via ACS 5.1 but can't seem to get the accounting details I require. Similarly I have tried to catch appropriate syslog messages but again without much success.
We have Cisco ACS 4.2 in our network and the accounting is done for 750-1000 devices and only for level priv-15.If i want to enable accounting for all levels from priv-1 to 15. All commands executed in devices are sent to ACS. Does the ACS can that much sessions from those many devices?Am also planning to configure acs remote agent to store all the accounting history.
i changed from ACS 4 to ACS 5.2. Everything works fine but i have authentication failed in the Radius accouting reports every time when users connect through ASA or Juniper into our network. Juniper amd ASA only send accounting informations to ACS. The users are not configured on the ACS, authentication is done via external LDAP. So my question is why do o see authentication error on ACS because Juniper and ASA only send accounting packets ?
I have a WLAN configured with 802.1x PEAP pointing to an external RADIUS server. It works fine for the most part, but I'm having problem closing accounting sessions in RADIUS. I've found this is related to the client table in the WLC. The user session does not end in RADIUS unless the WLC officially removes the client from the db, which takes 5-6 minutes from what I can see (probably due to the default idle timeout of 300 seconds).
For example:
1. I connect my tablet to the test WLAN. It associates and authenticates successfully and the WLC sends the accounting info to my RADIUS server, opening up a user session. If I turn off the wifi in the tablet, the client entry stays in the WLC client table until it times out. The WLC removes my tablet from the client table after 5-6 minutes, and then the session closes in the accounting table. I can force the session to close much earlier by manually removing the client from the WLC.
2. Same as #1, but this time instead of turning of the wifi in the tablet, I choose to connect to a different WLAN in the WLC. The user session in the accounting DB never closes. If I reconnect back to the original test WLAN with 802.1x, it opens up yet another user session in RADIUS accounting. Now I have a "dead" user session in accounting that is going to be open forever unless I delete it from SQL.
Is this an issue with the end user client not sending the disassociation frame properly, or a config problem with the WLC? How can I make it so that every time a client drops from an AP or moves to a different WLAN, the WLC would immediately send accounting updates to my RADIUS server and close the user session properly?
on the dashboard of the "Monitoring & Report Viewer" I see a lot of system alarms related to the database.The explanation of the alarm says to look at the Collector logs for the details.
I am using the CISCO SG300-28 with firmware version 1.0.0.27. I enabled RADIUS authentication and accounting. Authentication is working but there are no accounting requests/replys (Accounting on, accounting off, accoun ting start, accounting stop) when running RADIUS in debug mode. I also did a packetcapture and there are no accounting packets.
So i updated the firmware image up to version 1.1.2.0. When I now want to configure accounting in RADIUS settings then there isn't any option to set an accounting port.
Ich checked the data sheet of the switch and it says that accounting is supported:
=============================================== 802.1X: RADIUS authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple host mode and single/multiple sessions [URL] ===============================================
I did a second packet capture with the new firmware image and there are still no accounting packets.
The RADIUS server is configured correct for accounting because when using another NAS like a WLAN-AP with DD-WRT accounting is workings. It is working with pfsense Captive Portal (an open source firewall and routing solution with a hotspot portal).
I have a Cisco ACE 20, and I´m trying to set up a serverfarm for my radius server to load balance ldap udp accounting packets. The ACE has an LDAP authentication probe but I see no native way of setting up an LDAP accounting probe, without resorting to probe scripting.
I have an SG300-20 here for testing (firmware: 1.1.2.0, boot version: 1.0.0.4, language version: 1.1.1.6 English). Everything seems to work on it, except, that if I choose Radius authentication by mac address only, then the switch does not honor the Idle-Timeout and Session-Timeout attributes from the Radius server (freeradius).
The setup is the following: I have a no name access point plugged in to switch port gi1. The port gi1 is set up for Radius authentication by mac address only. The access point itself is authenticated, no problem with that. If I connect through the access point by (say) a mobile phone, it is authenticated, no problem. The radius server does send the Idle-Timeout and Session-Timeout attributes, I checked it by running "freeradius -X", both are set to 30 seconds. Then I turn off the wireless card in my mobile phone and check the dot1x users by "show dot1x users". My mobile phone's mac address remains there for 5-10 minutes, so the Idle-Timeout and Session-Timeout does not work.
Another way I could resolv this problem is by explicitely asking the switch to reauthenticate the user. Unfortunately there is no CLI command to do just that, I can do however a reauthentication on a port using "dot1x re-authenticate gi1" (for example). But it does not work as it is expected: the switch uses the stored mac-address to reauthenticate the user, so nothing changes on the port (unless something changes in the radius server). I think it should work like the following: remove the authenticated user from the port, and whenever that mac address makes some network traffic, then reauthenticate as if it were a completely new connection. BTW: it would work for me also if I could just remove an authenticated user from a port, but I did not find a command to do that.
As a last resort I can simply shutdown the port, bring it up again ("shutdown" and "no shutdown" in the interface config), then all users are removed from the port and they all mush reauthenticate. But it causes a network outage for a couple of seconds for all users on that port, on a busy access point it is quite disturbing, and it is not an elegant way to do this.
So my actual question is: is there a way to remove an authenticated user either automatically (Idle-Timeout and Session-Timeout) or manually from this switch?
I enclose the relevant part of the running config.
Is it possible for AnyConnect to utilise the backup server defined in the connection profile when the session limit is hit on an ASA? Essentially if I hit the 250 limit on my ASA 5510 in Region A, will it try the backup server ASA defined in the connection profile which is in Region B?
From what I have read, the backup server only kicks in when the AnyConnect client cannot connect, but in this scenario it will connect but get an error message.
We have a Cisco ASA5510 configured to work with Microsoft Radius Server. VPN authorization and authentication is working well with L2TP over IPSec, and users are authenticating with MSChapV2 like we want them to.
Now we are trying to setup Anyconnnect to do the same. How do we tell AnyConnect to use MSChap-V2 versus PAP? using ADSM? I think I know how to do the Microsoft Part of it, but I don't know where to go in ADSM to configure this.
Is it possible to send profile name as an Radius atribute during client authentication? I would like to match users depends on profile name to sperate Identity Stores in my ACS. ASA 5540 8.4, anyconnect 3.1.01065, ACS 5.1
I have been successfully able to setup Cisco AnyConnect VPN on ASA 5520 with 8.4 code. I have set it to authenticate against the RADIUS Server (Microsoft Windows 2008 NPS server). I have noticed one thing, on the server under "Constraints and Authentication Method". I picked MS-CHAP-v2, but it is considered Less secure authentication methods. I can click on Add and choose other Authentication methods like Smart Card or other Certificate, PEAP, EAP-MSCHAP v2. I picked PEAP but then the VPN does not work.
So first of all does it really matter if I just leave it to MS-CHAP-v2? Because from my understanding is that AnyConnect will authenticate to ASA and then ASA in the backend talks to the RADIUS server so from a security stand point this scenario shouldn't it be sufficient as no un encrypted or less secure information is available to the outside world? Secondly is there any documentation on using PEAP with Cisco AnyConnect?
We are in the process of upgrading our win2003 radius server with a new win2008 radius server. We have an ASA5520 and FWSM in 6509, using anyconnect client. This has worked fine until we introduced the win2008 radius server. When in the asdm on the asa, you can click on the new server and click test and authenticate ok with your AD credentials. But when try to use anyconnect on your laptop, it takes the credentials password and the accept certificate, but then fails with "anyconnect was not able to connect to specified gateway.." message, then "the secure gateway has rejected the connection attempt due to network connectivity issue...host or network is 0" message. We thought we setup the new radius the same way, obviously not. is therw an easy way to use debug on the firewalls to see what is wrong? looked in event logs on radius server, have not found anything.
Add the ability to send syslog events to multiple syslog servers in the SA500 Series routers. I know the functionality is currently in the RV220W because we utilized it. It would be great if you could configure the syslog servers by event type as well. For example, being able to send the kernel events to syslog server A, and all other events to syslog server B.
Recently i have upgraded the IOS of ASA5550 (in HA mode) to 8.4.2 from 8.0.5, after OS upgrade we found that the syslog from thses firewalls are not getting captured/transfered to centralised syslog server. The server is reachable from the firewalls.
If I choose to authenticate NCS users through Cisco ACS (5.4 in this instance) via TACACS, do I still have the ability to do accounting to track what changes they have made? I'm not getting anything in the TACACS accounting reports and I don't see anywhere to configure TACACS for accounting within NCS gui like I can on a WLC. I know that NCS has an internal audit trail but if a users account is both a local account on NCS as well as an account being authenticated through ACS does the Audit trail on NCS for that local user still contain the information about changes the user made? I ask because it looks like it does but I want to make sure I'm not going mad. Here is my example:
Local account username: NCS_Admin2AD account via TACACS username: NCS_Admin2
Audit trail for the NCS_Admin2 account on NCS looks like changes are being logged to NCS even though the user is logging in with their AD credentials via TACACS.
it seems there is no option for flexconnect registered AP's to work with external accounting server.I am using zeroshell server to authenticate with the radius server,which works perfectly!but there is no option under flexconnect security group to specify accounting server.is there a way to redierct AP to a local acoouting+authentication radius ?
I've got an issue with my ACS 5.1 implementation not updating any of the RADIUS or TACACS authz, authc, or acct records. Nothing is showing up, even though i've logged in via TACACS to several devices, and there are numerous wireless devices authenticated and online via RADIUS right now.
How to configure ACS 5.1 local administrator accounting and where have to check the accounting log . suppose administrator logged in to ACS and created some user or delete users where will see the log , which user have they created or deleted.
ACE is configured to point accounting to ACS servers but ACS servers are not seeing all the accounting logs. I can only see accounting logs from ACE for watchdog, start and stop.
Following best practices on cisco documentations we did set aaa acounting update periodic 5 with 250 switches in the deployment every single switch is geneating and sending 9.990 acct records this is too much the new testing parameterswe are using is aaa acounting update newinfo periodic 15 and this lowered accts by 2/3 (3500) moreover from switch monitoring the most accts records sent by it are related to the trunk-port any suggestion to mitigate this informations storm rather than raising the 15 min period to higher values?are this records generating from the trunk port normal?
I am working on cisco ACS 5.0, authentication is working fine on netscreen. Can acs be used for authorization and accounting of netscreen devices. if yes, what will be the configurations.
I am setting up reports for tacacs accounting on ACS 5.3. However, accounting only seems to work after entering enable mode on the switch. I would like to see all commands, even the enable command when in privlage 1 mode.
I have installed DCNM 5.2(2c) on windows box to manage Nexus 7K devices.\ have for the time being one device that i have manage and i see often the following text:Discrepancy in device accounting log,Recommended action: clear the accounting log and discover the device. Device details are not available.How can i delete the accounting log and why do i have this message ?
Struggling to find any documentation that states both "ip accounting & netflow" are supported on the new ME3600 switches. I have tried both a 12 and 15 release of software. Netflow produces no data what so ever, ip accounting only produces data (of the global network) when configured on my uplink (running MP-BGP network) unable to get specific data for user networks in seperate VRFs. Is this a case of the commands being there but not being supported?
I have a Cisco 2621XM router with two ethernet interfaces that sits before a vendor supplied VPN router. I need to see the IP traffic incoming to my router from the WAN side (fasteth0/1 below). I setup ip cef, and ip flow ingress on the interface. However -- it seems that what I see when I use "ip cache flow" command doesn't have a very long history or life. What commands am I missing so that I can see a summary of the stats over say the last 5, 10 or 15 minutes? Is this the best config that can be used for this, or can I create a more summarized report just using the router HW and IOS?

The "Cisco Small Business 300 Series Managed Switches Administration Guide" and the data sheet indicate that this switch can do accounting requests with a Radius server. On the SF300 switch interface/CLI, there is only the authentication port, the accounting port can not be set (and nothing is sent by the switch to the default port). I suppose that the SF300-08 does not handle accounting. Maybe I have to change for another model.
