Cisco VPN :: ASA 5510 - Radius Have Too Little Memory
Apr 19, 2009
I am doing the initial configuration on our ASA 5510 to use our Radius server just as our 3005 VPN Concentrator did. I can do the test connection inside the ASA with no problems, and when I authenticate using the Anyconnect client, it appears to authenticate fine, but then dumps the connection with an error stating there is not enough memory in he ASA to allow this connection, the error message is as follows:
Error Message %ASA-4-722004: Group group User user-name IP IP_address Error responding
to SVC connect request.
Explanation There is not enough memory to perform the action.
Recommended Action Purchase more memory, upgrade the device, or reduce the load on the device.
Can this really be the case with no connections active, a single user attempting to authenticate through Radius and an out-of-the-box ASA 5510?

I have an ASA that is logging the message %ASA-3-321007: system is low on free memory blocks of size 2048. I ran the "show blocks" command and the "Cnt" value for the 2048 blocks is 0. How do I reclaim these blocks and what are they used for?

Just want to check with you about memory utilization on the Asa 5510 ..
Free memory: 19%
Used Memory: 81%
Is this normal? Because we hade a problem this morning and the memory was at 100%..
Device Manager version 6.1(5) 57
Hardware: ASA5510-K8, 256 MB RAM, CPU Pentium 4 Celeron 1600 MHz
Internal ATA Compact Flash, 256MB
BIOS Flash M50FW080 @ 0xffe00000, 1024KB

I am trying to load the anyconnect VPN client package v3 for windows and Mac on ASA 5510. The ASA has 256MB for RAM and Flash. After I uploaded pkg files and selected the 2 files and applied from ASDM, ASDM spots responding...
I tried to tftp the running config from ASA to my laptop to analyse but got "No memory available" message...
So it seems like the "unzip" process of the pkg files used up memory... what is really the requirement of the mini Memory/RAM on ASA for hosting anyconnect Clients for 2 OS platform? Requirement on Cisco web site is kind of vague.

We want to run ASA 8.4.x on an old ASA5540. We need to upgrade its memory to 2 GB with the following memory upgrade: ASA5540-MEM-2GB=
I suspect that we will completely remove the existing 1 GB of memory and replace it with 2 GB. If this is the case, can I use this 1 GB of memory removed from the ASA5540 and put it in a ASA5510 instead of buying a ASA5510-MEM-1GB= for the ASA5510?

We recently added about 400 users to our network for a total of 1000. Looking at the ASDM we are holding very tight to 75% utilization and we have 256mbs. This is also running IOS 8.2(1). Our firewall recently crashed after a major download was forced through it. This was after only being booted up for about a week. We had reloaded it a week prior after having ran it for about a year without issue. We havent made any changes in the last month other than adding more users to our network.

Are the ASA memory DIMMs created for specific models? Would a 1GB 5510 Memory stick work in a 5520?

I have a 5510 authenticating successfully with a RADIUS server. I'm using it for VPN authentication and it works great. I would also like to do this for administrator access to the ASA. When I turn it on though, any authentication for VPN access is also granted administrative access to the ASA. Obviously, I need to limit that to a select few users.

currently I'm evaluating an ACS 5.2.I need to authenticate the VPN-Users against LDAP, but have no direct connection from the ASA to the LDAP-Server. So the ASA should connect to the ACS to ask the LDAP-Identity-Store, OK.
My first Problem is: the ACS doesn't respond to the RADIUS-Requests of the ASA! ASA use's Port 1812, the Secret is ok, the ASA is as a Network Device in the ACS configured and I've created an internal Test-User on the ACS.the Firewall-Log shows the established connection (so I think, there is a Hand shake!? ), but the ASA says in Radius-Test: "EROR:Authentication-Server not responding".

I'm using Cisco VPN client 5.0.7 and Cisco ASA 5510 (7.4 and 8.4.2) VPN RAS solution. Clients are authenticated using certificates and AAA RADIUS (ACS 3.3) and AD.Each time, when client connects, ASA issues 2 RADIUS requests, first - correct one which is successfully authenticated by ACS and immediately - second which always fails. I couldn't find any information related to this strange behaivor. "Double authentication" feature (most likeable to its name) is accessible only to Anyconnect clients which we don't use. When I'm authenicated using group password, there is only one RADIUS request.What is the source of such behavior?The negative impact is that my logs are filled with spurious failed auth attempts, and users are incrementig failed attemps counter in AD.
Debug from ASA:
----First request----

I've setup my ASA 5510 to use AAA to my Windows Server 2008 NAP. After many hours of troubleshooting I got my setup to work. The only thing I'm not satsified with at the moment is, that RADIUS is using PAP for communicating between ASA5510 and W2K8/NAP.I've tried ticking the box "Microsoft CHAPv2 Capable" box under Users/AAA => AAA Server Groups => Edit AAA Server.From EventViewer on W2K8/NAP I get Event ID 6278 and 6272., see attached filehow I change from the PAP to the CHAP protocol?
PS: ASA 5510 running ASA version 8.2(4) and ASDM version 6.3(5)

I'm on an ASA 5510 running 8.2(5)41. I have clientless WebVPN configured to authenticate against an RSA RADIUS server, which has users assigned to RADIUS Class attribute 25 to match the group-lock values assigned to each ASA group-policy. This of course is to ensure users can only access the login page's drop-down VPN profiles they are assigned to by the RADIUS server. I have two other ASA 5510s (same code level) using the same RADIUS server with group-lock enabled but for IPSec remote access VPN's, and the group-lock feature works fine.
WebVPN, however, is authenticating any user to any VPN profile without regard to the RADIUS Class attribute 25 they are assigned. If I configure the VPN profiles to authenticate locally and assign group-lock to individual ASA user accounts, group-lock works. As soon as I point it back to the RADIUS server, group-lock does nothing. From the 'debug aaa' below for user 'corpvpnstp', you can see the RADIUS server sends back the attribute 25 values of "ou=stp.Client;" and "ou=stp.ClientDRC;" for this user. The ASA profile this user has attempted to connect to is "EMS-Admin", which should get denied by the ASA. Instead, the ASA successfully authenticates the user.

We are starting to deploy SSL VPN in our company and we recently purchased two ASA 5510 firewalls. I have already completed the initial configuration but I do have some inquiry on how to have it configured properly.
1. Employees and clients will access the URL
2. They will select the appropriate group on where they should login.
3. Enter credentials, etc.
4. Username/Password authentication is via RADIUS. The usernames were all created in Cisco ACS 5.3.
My challenge is, we have several clients and all their usernames were created in ACS5.3. Meaning if the configuration is just being differentiated by group settings, clientA can select the profile of clientB and still get authenticated. If that happens, they will be able to access the resources of each other. Also in the future, we will be deploying 2-Factor authentication for some of our clients.

I tried to authenticate and authorized Nokia/checkpoint Nortel/AD3 and Nortel 5510 platform using an 4.1 for windows ACS. the ACCESS-REQUEST is well processed bi the radius server wich send ACCESS-ACCEPT to the AAA Client (ie NORTEL or NOKIA), but i'have got privilege access denied on the Client side. RADIUS IETF Dictionnary is used for every device. all others Cisco Devices authenticate and are well authorized.

How would I go about configuring RADIUS based AAA for remote access VPN users? I have an OSX RADIUS server and an ASA 5510
(I want to keep console and SSH using LOCAL, so I keep this: "aaa authentication ssh console LOCAL", right?)What does the rest of the config look like to get RADIUS based AAA for remote access VPN users?

We have several ASA 5510 firewalls which are being used as VPN gateways.RSA SecurID is the authentication mechanism using native SDI connectivity. No ACS server is being used.Is it possible to assign user Group and other attributes (such as ACL), using the SecurID RADIUS server? I know this is what the Cisco ACS is for, but is it possible using the RSA RADIUS server itself?

I am attempting to configure Radius authentication accross a site-to-site VPN for my ASA 5510-01 for remote access.
ASA5510-1 currently has a live site to site to ASA5510-2.
ASA 5510-1 - 10.192.0.253
ASA 5510-2 - 172.16.102.1
DC - 172.16.102.10
ASA5510-01 can ping the DC and vica versa but is unable to authticate when i perform a test. ASA5510-01 can authenticate to a DC on it;s own LAN but not on the remote LAN that DC sits on.
I have double checked the 'Server Secret Key' and ports as well as various users which all work locallly. ASA5510-02 authenticates to DC with no problems.

Upgrading the memory on an 1841. After inserting a 256MB/PC133/SDRAM/DIMM it would not post during the boot, hangs.If i take out the chip it works fine.The on-board memory is 128, so the 256 is the max it would take to a total of 384. According to the documentation this should work.The memory chip is a Transcend chip, basically Samsung.

The issue is when I am using PPTP the router seems to die, not every time but I would say about once a week now. I am the only PPTP user, simply using RDP. A few hours into an RDP session the PPTP connection drops and cannot be re-established, or quickvpn, nothing. Routing still works (somewhat, high latency) locally.
When I've checked the logs both times I see:

We have recently purchased a brand new RV042G VPN router, set it up, and had it running for a while without issues.
Now that we are actually trying to use the VPN functionality, the router becomes unstable after a while, showing "out of memory" lines in the logs, and after a day or two the VPN stops working completely and the web interface becomes completely inaccessible.
This issue happens when using any sort of VPN that's supported by the router.

I've deployed many Cisco PIX 501 v6.3.3 either as normal firewalling feature and/or with VPN features enabled. I noticed in all my deployments, regardless if it's during peak hours or after office hours, the memory utilization is always consistent 11MB utilized over the total of 16MB(memory default size).

The problem is router hangs out , intenet users suffer slowness , criticle service like telnet doesnt work . the only solution i found is a reload ,not to mention this is core router sitting on campus network edge . and servicing around 1000 users !! approx assuming all users have using internet at same time .
how to check , if memory is not sufficient ?further if any users using utorrent or any thing like that , does it make enormous no of connections form same pc ?
is their any licence requird for IOS IPS ?i prefer to turn this feature on to kill torrents connections ? but i fear crashing of router as no of users are huge !any know bug with glbp , nat with ip voice image C3825-IPVOICE-M VERSION 12.4(24) T4 ???

Any known problem with the DRAM on 2800 routers? Over the past few months we have had four 2800s fail to reboot after power off/on and in all cases this was due to faulty DRAM. All four routers had been working fine for months with no problems and only failed after being rebooted. They all failed when trying to load the IOS into memory and therefore all got stuck in rom mon. The compact flash cards were all ok as a working 2800 booted up using the flash from the faulty routers. I haven't seen a field notice so are we just unlucky here?
