Cisco AAA/Identity/Nac :: Enabling ICMP On ACS 1120?
Feb 28, 2011
We have downgraded cisco acs appliance 1120 from ACS 5.0 to ACS 4.2.1.15 , when we perform ICMP ping request to acs appliance its not responding , But i can do ping test from acs appliance on console mode not from GUI mode .
Is there any option to enable ICMP Ping response on cisco acs 1120 . else any patch to be upgraded to perform this action , my requirement is enable ICMP ping on acs appliance for troubleshooting . instead always check with telnet x.x.x.x 2002 for service responding

I´m currently looking for a document that specify how many MAC addresses can be stored and authenticated via an ACS (1120)? I prefer to use the internal identity store over AD or LDAP for MAB authentication for 802.1X project. I would like to know what is the impact on the ACS? CPU/MEM? What is the impact on the user authentication? delay, timeout, etc.

I encountered some strange issues with one of our appliances in the field. Reinstalled and encountered the strange issues. No errors.. did some memory test and the seagate harddisk test and encountered SMART errors. The device didn't log those errors anywhere.. First reason to check the second harddisk. The appliance is shipped with two so the first thing I was thinking of was RAID. I saw that raid wasn't configured. Try to boot the second harddisk and saw that nothing was on that disk.. so what is the mean reason you got two of those? Got the new machine and try some options to configure RAID.You got two options.. didn't see this before, most of the time you got only one option. Raid driver on or no RAID configuration at all. First tried the intel storage matrix, configured both of the disks for mirror and install the ACS 5.2. The machine boots after installs and rejects the DVD. Result: The installation doesn't boot! Checked the partition with gparted but the partition is active (or flagged as boot) Second option was LSI, got the raid configured for mirror and the installation was also completed. Result: working installation. Tried to test if the installation is still working after removing one of the disks. Appliance is complaining the the RAID is missing one disk (so this works). After that the machine tries to boot, result: no working ACS.

I have an ACS applicance that had a version 5.1 and i did an upgrade to 5.3 with latest patch.For some reason, the runtime process got stuck in (reinitializing and restarting) state.i did the recommended action to perform ACS stop and ACS start and even hard reset of the appliance, but it did not cut itThis process turned out to be a bug and it should have been fixed in version 5.3, but it has not i guess
i know that acs reset-config will solve the issue, but i have a problem here , the license file will be deleted as well with the config and i cannot find a way to export the license and then import it into the reseted config ACS hardware. Unfortunately, the license file is not saved anywhere in the company and i cannot affort to lose it.how to export the license from the applicance (CSACS-1120)?

i am configuring a Cisco Secure ACS 1120 appliance running ACS 5.0.0.21 to handle RADIUS request from a Cisco WLC 5508 appliance running version 7.0.116.0.these devices have open communication on all ports - no firewalls or ACL'sthey have successful ping communication The following statements illustrate some but not all the debugging I have done to ensure each device functions as it should in isolation.Using a simple windows RADIUS server (radserv2.exe) instead of the Cisco ACS This works and the WLC gets RADIUS response from my makeshift serverUsing a simple windows EAP client to query the ACS using RADIUS protocol this works and the ACS processes the RADIUS request and sends a responsePlaced a wireshark client on the network to inspect timeout. Wireshark logs the packet from the WLC to the ACS using port 1812 but doesn't see any packet responses from the ACS At the moment I have the WLC accepting the association from the wireless client and sending the RADIUS (PEAP, EAP-FAST or EAP-TLS) request to the ACS, the WLC receives no response and generates a timeout message and disassociates from the client. note this is not a reject or similar message, the ACS simple does not even process the packet. i.e. there is absolutely nothing in the ACS logs to suggest it even received a radius packet from the WLC. In summary the WLC and the ACS successfully function independently but they do not communicate via radius.

I have problem with ACS 5.0 on reporting. On "Monitoring and Report" page in Faverite Reports when i clicking on "Authentications - RADIUS - Today", My browser displays error "Error while reading skin-access.config. Please make sure the file exists and conforms to the schema specified"
I must also mention that I never upgraded the version of ACS from 5.0 also from command line all the acs services are running. It is running on CISCO 1120 Secure Access Controll Server apliance.
My second question is can I upgrade the version of ACS to 5.4 with Cisco Secure ACS 5 Base License?

When attempting to register an ACS instance to a primary (via System Administration -> Operations -> Local Operations -> Deployment Operations), I receive the following error as a popup in my browser:
"This System Failure occurred: /opt/CSCOacs/db/acs.crt (No such file or directory). Your changes have not been saved.Click OK to return to the list page."
I had 2 ACS 1120 appliances clustered, 1 suffered a hardware failure about a year ago so I replaced it with a VM. That one is now the primary. I'm now wanting to replace the secondary instance (the remaining 1120 appliance) with a VM as well. I removed the current appliance from the network, installed the VM using the same IP address, and attempted to register. It failed as per the above error. After trying this a number of times, I then decided to return the 1120 appliance to secondary status and attempted to register it with the same results as above.

i have 4 X ACS-1120. Each 2 are operating as an Primary and backup. I want to add a license in order for the ACS to support more than 500 networks which includes in the base license.As I understand this is the license required : L-CSACS-5-LRG-LIC=
·
Is this license applicable to ACS-1120 appliance with ver 5.2 ? – I understand that it is. for my scenario, do I need to purchase total of 2 X L-CSACS-5-LRG-LIC= (one for each environment, one license will serve 2 X ACS in Primary and Backup) or I need to purchase 4 licenses each for each ACS ? – I understand that one license will serve deployment of two ACS in primary and active scenario.

I'm trying to join a band new CSACS-1120 to our active directory without success. The process in it self should be pretty straigh forward, but so far no luck.
I've configured the relevant info under "Users and Identity Stores > External Identity Stores > Active Directory.
Active Directory Domain Name: xxx.com
Username/Password : domain administrator account
When I test connection I get a info dialog "This machine is currently connected to domain xxx.com".After which I try to save changes which gives a reply ""This System Failure occurred: {0}. Your changes have not been saved. Click OK to return to the list page."
I've noticed that in the system log "show logging system tail" that I get a exception as soon as I enter the AD configuration page and subsequently every time I perform a action on that section.
Why the AD join keeps on failing and what the debug exception I'm getting means?

I am running windows based acs 3.3 in my lan environment going to be replaced with acs 1120 appliance running acs 4.2.1.15 , ACS 3.3 database has been built upto 4.2.0.124 ,step by step by upgrade process
1) acs 3.3.3.14---> 4.1.1.24
2) acs 4.1.1.24 ----> 4.2.0.124 .
now my database is with 4.2.0.124 dmp file , I cannot upgrade my database to 4.2.1.15 because 4.2.1.15 patch is not applicable & executable on 90 days evalution package of 4.2.0.124 of windows platform .
can i import my windows based 4.2.0.124 datbase directly to my acs appliance running 4.2.1.15.3 ??? , else its requires any step to be done to modify the windows based databse matching to appliance windows verison once .
I could see on appliance under restore settings the following options (restore from 4.2.0 backup file to acs 4.2.1)

I need to reuse this same SSL certificate on my acs appliance .ACS appliance certficate setup requires following two certificate to be installed for PEAP clients authentication
1) Server Certificate
2) CA certificate
Server Certificate : For server certifcate , I have my old certificate which is exported from my old acs 3.3 server , when i tried to download my server certficate via ftp server on my acs appliance , its looking for private key & private key file .Private key & file is generated intially on CSR request when this server certificate is requested to CA vendor for my old acs 3.3 . I dont know the private key password . If i need private key & file , then i need to generate new CSR from my acs appliance and i need to submit this CSR output to my CA vendor to generate new SSL server certificate .which is something like new server certificate request .CA certficate : For CA certficate , when i open my existing SSL certificate under detials tab in CRL distribution point , i could see below URL . whn i open this URL it giving certificate revocation list .

I've recently installed a certificate on my ACS 1113 appliance and in the Admin setup enabled management access over HTTPS. Since then I've not been able to access the GUI console. I have done some troubleshooting and I'm fairly certain that I have a certificate issue as Firefox gives me the error: Certificate type not approved for application. (Error code: sec_error_inadequate_cert_type)when I try and connect. So I want to either reconfigure the management access to use just HTTP or remove the certificate. I have logged on to the serial console and there are no options her to do this. The RADIUS and TACACS functions are working correctly - I just can't logon via the GUI.

I cannot seem to ping between devices on two networks hanging off a 5520 unless I use the same-security interface command. I have the relevant ACL's set up between the interfaces, but it just doesnt work unless I have that command in - if I use that command, it bypasses the ACL.
Config
interface GigabitEthernet0/0.224
description NMS
vlan 224

More and more recently I'm seeing that inspect ICMP and ICMP error do not allow trace route to work through the firewall from inside to outside.I used to go in, enable the inspections and subsequent trace route's worked. Now when this is enabled, the firewall still blocks return trace route.

I'm new to the Cisco WLCs and recently implemented a wireless infrastructure using a WLC 2100 with 1262 LWAPs. I have two of the 1262s plugged into ports 7/8 using crossover cables. They're functioning correctly with the exception of the inability SSH and send pings to the LWAPs behind the WLC. Is there anyway to ping/shh through the WLCs to the LWAPs behind it? I use an NMS (Nagios) to monitor the status of the LWAPs and it can't monitor them if it cannot ping them. Also, is there anyway to configure the WLC to monitor the status of LWAPs?

Have a very peculiar issue with IP SLA. Firstly, the architecture.
1) There are two sites - A & B. Both have their own internet connection.
2) Sites A & B are connected via MPLS.
3) Both sites have the below topology.
3750 CORE --> FIREWALL -->ROUTER ---> INTERNET
4) 3750 has a Default route pointing to firewall .
5) MPLS router is connected to 3750. A default information is originated via BGP to MPLS at each location. So that default route is learnt as a backup path from any location if it has to lose its local internet.
6) IP SLA has been configured at each location to track the default route using icmp-echo to hit a public IP (i.e 4.2.2.2 as an example).
Issue?ICMP probes from Site-A via its local internet fails abruptly. I can reach the public IP mentioned above from my firewall pretty fine, but not from my 3750. Whenever i remove the tracking from the static default route & push in the plain default route without tracking, it works fine. Again, if i add the tracking back, it will work fine for an hour or so & then fails back again. To my bad, Site-B had recently gone offline due to some natural calamity. So, there is no other path for internet.
My config looks pretty simple
track 10 ip sla 1 reachability
!
ip sla 1
icmp-echo 4.2.2.2 source-ip 10.1.254.1
frequency 180
ip sla schedule 1 life forever start-time now
ip sla enable reaction-alerts
!
ip route 0.0.0.0 0.0.0.0 10.1.254.1 track 10
I am running IOS version 12.2(53)SE2 (IPservices images).

So I have my shiny new (used, but new to me) 5510 finally working and installed in my Dev network. I need to have icmp (ping and trace route) available from the inside network. I Google and found a few articles on how to do it. I tried modifying the class maps, but it looks like there are changes in the commands in 8.4 and the articles I found evidently were for 8.2 and lower. I tried doing it with access lists, again from examples and traffic stopped in all directions (not good) so I am back to being functional and how to do it in 8.4. Documentation seems sparse on the net with 8.4
