Access Cisco ACS v5.3 via 2FA

Hi All,
I would like to configure login to ACS v5.3 via 2FA. Does ACS v5.3 support 2FA for its login?

Hi Eduardoaliaga,
I believe that when we are using PAP as the authentication protocol, the ACS is able to strip the domian prefix. However, my side is using the PEAP MsChapv2 as the authentication protocol and I believe that the TLS tunnel is prevent the ACS from stripping the domain prefix/sufix. Thus, I have also posted another discussion on the issue of when the authentication protocol of PEAP MsChapv2 is used, ACS is not able to strip the domain prefix/sufix. Thus, would you be also able to advice on if that is correct. Please refer to the links below.

Cannot access Cisco MIBs via SNMPGET

Hello, I'm sure this is a simple fix and I'm too stupid to figure it out, but I'm having trouble accessing Cisco ACE specific OIDs via Net-SNMPs tools. If I run snmpwalk on the device, I get a nice list of standard SNMP OIDs such as SNMPv2-MIB, IF-MIB, IP-MIB, etc with values such as the device name, interface IP counters and all that stuff. But I don't see any Cisco specific OIDs in the list. I really want to be able to monitor the load across real servers and server farms and such on this ACE module.
So, for example, I try running the following command and it says no such object:
snmpget -m +CISCO-SLB-MIB -On -v 2c -c communityname ipaddress CISCO-SLB-MIB::slbServerFarms
.1.3.6.1.4.1.9.9.161.1.2 = No Such Object available on this agent at this OID
I read you should try adding an index to the OID as there may be multiple sub objects (and of course there are multiple server farms) but I get the same thing:
snmpget -m +CISCO-SLB-MIB -On -v 2c -c communityname ipaddress CISCO-SLB-MIB::slbServerFarms.0
.1.3.6.1.4.1.9.9.161.1.2.0 = No Such Object available on this agent at this OID
Just to confirm a valid OID, I get this:
snmpget -m +CISCO-SLB-MIB -On -v 2c -c communityname ipaddress SNMPv2-MIB::sysDescr.0
.1.3.6.1.2.1.1.1.0 = STRING: Application Control Engine Service Module
I also tried snmptable with CISCO-ENHANCED-SLB-MIB::cesServerFarmRserverTable and it just says "Was that a table?"
So I think it must be a permission problem or some config that I have to tweak. Right now the only SNMP config is:
snmp-server community communityname group Network-Monitor
My device version info is:
Software
loader: Version 12.2[120]
system: Version A2(1.4) [build 3.0(0)A2(1.4) adbuild_11:54:12-2009/03/05_/auto/adbu-rel2/rel_a2_1_4_throttle/REL_3_0_0_A2_1_4]

Thank you for your help!

This is an interesting thread, and probably something which is unclear to a lot of people. Tables and their entries (think header rows) are inaccessible because they do not contain data directly. Data is only contained in the cells within the table. The cells in this case are the SNMP objects defined within each table entry (or row). So, a table is inaccessible as a whole, but each of its data cells can be accessed.
If you think of it like a spreadsheet, it may be a little more useful. But let's try a visual.
cesServerFarmRserverTable
cesServerFarmRserverPort
cesServerFarmRserverAdminWeight
cesServerFarmRserverOperWeight
80
100
100
8080
50
10
The header row in this table is called cesServerFarmRserverEntry. It contains the column names for our data. Each row has a unique number associated with it. That is the cseServerFarmRserverPort. In a typical spreadsheet program, this would be the column at the far left which you cannot edit. It just enumerates the rows. In this example, that column is named cesServerFarmRserverPort. If I wanted to tell someone how to get the value of cesServerFarmRserverAdminWeight at a particular row, I would say, "go to row 80, and read the value from the cesServerFarmRserverAdminWeight column. In this case, they would read 100.
SNMP operates in the same fashion. For one to get a specific value (i.e. perform an SNMP GET), one must know the specific column name and row number. In the actual case of the cesServerFarmRserverTable, the row number is actually a combination of the slbEntity, slbServerFarmName, cesRserverName, and cesServerFarmRserverPort, but the concept is the same. You can only do an SNMP GET on a precise address in a given table (i.e. on a cell). To do a GET on cesServerFarmRserverTable directly would make no sense since an atomic value could not be returned.
An SNMP Walk, on the other hand, allows you to start with the table itself, then walk through each cell in the table, printing out the value at that cell.
A tool like snmptable essentially performs recursive GET-NEXT queries to walk through all of the rows, then print the value of each cell in a tabular format.

Linksys WAP54G connecting to CISCO ACS via LEAP

I understand that Linksys WAP54G support WPA and 802.1x authentication. Will a cisco compatible client card get connected to the WAP54G via LEAP authentication to a Cisco ACS server ?
Connection scenario:-
Cisco compatible client card <-WPA/LEAP-> WAP54G <-WPA/LEAP-> Cisco ACS3.1
Pls advise if such setting is feasible.
Tks

This is really a question for Linksys support. The Cisco wireless BU has no involvement with the Linksy's product line. They operate as a totally separate wholly own subsidiary of Cisco.
As for LEAP, no, to my knowledge the Linksys AP does not support LEAP, which is not tested or part of the WPA certification program. To my knowledge the ONLY APs that support LEAP are Cisco Aironet APs.
If the Linksys supports WPA-Enterprise, then any client that supports WPA-Enterprise should work using EAP-TLS. The Cisco ACS server supports EAP-TLS.
One word of caution. Early CCX cards do not necessarily support WPA. The CCX specification and certification were out before WPA was released. You will need to check with the actual vendor of the card to verify WPA compatibility.;
Also there are two types of WPA. WPA-Personal, which supports only the WPA encryption, and the keys are handles by a Pre-shared Key input system (no radius server) and WPA-Enterprise, which is certified using WPA encryption an 802.1x EAP-TLS radius server (in fact using Microsoft and Funk Software servers). make sure that the Linksys supports WPA-enterprise, or it may not support 802.1x.

Cisco acs 4.2 for bandwidth management

How can i configure this feature ?

Jatin,
Currently we're using TACACS+ for authentication. We
Here's a description of the requirement for 2 factor authentication:
Id - NET0431
Vulnerability
Discussion
AAA network security services provide the primary framework through which a network administrator can set up access control on
network points of entry or network access servers, which is usually the function of a router or access server. Authentication identifies a
user; authorization determines what that user can do; and accounting monitors the network usage. Without AAA, unauthorized users
may gain access and possibly control of the routers. If the router network is compromised, large portions of the network could be
incapacitated with only a few commands.Default Finding
Details
AAA server does not redirect/call to a two-factor authentication server.
NET Authentication Access
Procedure: The implementation varies and a thorough review is necessary. Have the SA review and discuss their
implementation. A typical AAA process includes the network system redirecting user access requests either directly to an
ACE/Server or to a CiscoSecure ACS (TACACS+) server which redirects the 'authentication' request to the ACE/Server for
strong authentication via user tokens (keyfobs). During the review have the SA point out the calls from the TACACS+ or Radius
servers to the authentication server performing the two-factor requirement
From my understanding ACS can meet this requirement, I just need some ideas or case studies to see how it how implemented.

Cisco ACS v4.2

Hi,
I have created admin user in a Cisco ACS v4.2 used as TACACS+ server. Now the admin user ic created under the "default" Network Access Profile. However I would like to add another Network Access Profile to this admin user whiel maintaining the existing Network Access Profile.
Please tell me how to achieve this?

Your understanding of the issue is correct. The certificate installed in ACS is being used by wireless/wi-fi authentication and secure-http access (if configured). In case it expires, only wireless authentication and secure http access will be down. The network devices will continue to authenticate via tacacs. I guess LDAP in your case is actually acting as a backend database so radius or tacacs sending the user request back to the external database.
Now, even if certificate expires, you've always an option to generate slef singed certificate until to you get the new third party certificate from you CA. Self-signed Certificate Setup (only if you do not use an external CA)

VPN client and Cisco ACS

hi,
I'm trying to setup a VPN solution, connecting to a 800 series router and authenticating off a Cisco ACS tacacs server.
I've basically followed the suggested config at http://www.cisco.com/en/US/customer/tech/tk59/technologies_configuration_example09186a00800a393b.shtml and the setup works fine if I use local authentication, but as soon as I switch to using TACACS the client authentication fails.
Debugging tacacs on the router i can see the requests being sent to the server, and the replies coming back - the login detail are definitely correct so I'm guessing that TACACS isn't authorising me to use VPN or IPSEC or something. But there is nothing in the ACS logs to suggest why I'm not getting through - no failed attempts are shown.
Any ideas?

here is some debug from the router:

"AUTHEN/REPLY status:5" is a permanent fail according to the TACACS RFC
In the VPN Client log it say "User does not provide any authentication data"
So to summarise:
-Same ACS server\router\username combination works fine for telnet access.
-VPN works fine with local authentication.
-No login failures showing in the ACS logs.

How to hide line console parameters through Cisco ACS

Hi,
Can any one of you please help me in the following scenario ?
I want to hide the line console, line aux and line vty configuration parameters of the cisco devices based on user level privillages through Cisco ACS. For example, if a user logs into the devices with privilege level 7, then he should not be able to see the line paramenters on the cisco devices for which he had privilege level 7 access.
Can you please help me out how to achieve this?? Your help in this regard is highly appriciated.
Thanks

This thing is possible with local authorization on IOS device. With ACS this is not possible.
In acs you can set what all commands a specific user can issue. That feature is called command authorization.
For show run you need to give priv 15. ACS works in a different way if you compare it with setting up local priv lvls on router/switch.
Best way to set it up is to give all user priv lvl 15 and then define what all commands user can execute.
Note : Having priv 15 does not mean that user will able to issue all commands.
We will set up command authorization on acs to have control on users.
This is how your config should look,
aaa authentication login default group tacacs+ local
aaa authorization exec default group tacacs+ if-authenticated
aaa authorization commands 1 default group tacacs+ if-authenticated
aaa authorization commands 15 default group tacacs+ if-authenticated
aaa authorization config-commands
aaa accounting commands 1 default start-stop group tacacs+
aaa accounting commands 15 default start-stop group tacacs+

Cisco ACS 4.2 - Server Busy

Hi!
We're authenticating our Desktops and IP-Phones via 802.1x using two Radius-servers running Cisco ACS v4.2 on Win2k8.
From time to time we run into the problem, that one of the servers 'get's too busy' and stops answering authentication requests. That results in many failed authentications with our VoIP-phones (Siemens OpenStage).
What I don't understand is why the ACS acts that way...
TAC says that all 42 or so threads are in use when the server says it's too busy.
While the server is 'busy' the CPU runs at 1 - 2 % !! And there's loads of RAM left...
This is an extract from the CSRadius-Log-File:

Did any of you encounter the same problem? Did you find a workaround or fix? Maybe there's a way to increase the number of authentication threads?
Thanks alot!

The key is to get all of the information needed. Normally when they say it takes too long for the client to answer that is not always the exact fault.
You may seem to get that answer if the ACS is taking a long time to process the request and the switch or client has basically timed out its requests.
The information needed is the following
all of these items really need to be gathered at the same time
switch debugs including
debug radius
debug aaa authen
debug aaa accounting
sniffer capture between the switch and the ACS
logs from ACS with debugs enabled.
If you are going to AD on the backend you may also want a sniffer capture between the ACS and the AD
all of these together should tell you where the delay of failure lays and then at that time some changes can be suggested

Rendering a Cisco ACS page is broken in Firefox 15

Since updating to Firefox 15, a page inside my Cisco ACS appliance does not render: Access Policies > Access Services > Default Network Access > Authorization.
The page has historically taken 15-20 seconds to fully load its contents, and the page now renders as if Firefox 15 got sick of waiting and just displayed what content it had. Is this a problem with rendering the page or perhaps did the value of a timer get changed in Firefox 15?
The Cisco appliance is not public-facing, so I am happy to do a screen-sharing session with a Mozilla engineer if it would help troubleshoot. Thanks.

Still broken in 16... Great, now I have to run a version that is 2 versions old.

Cisco ACS for Unix authentication

My company is looking for a single sign on for all the windows and unix servers mainly for admins. I was wondering if Cisco ACS will work for this.
Basically the authentication will be all for the servers and routers ofcourse. I am thinking if I specifies windows AD in ACS config, Can I get the unix boxes to get authenticated against Radius?
Any help will be appreciated.
Manny

Hi,
Authentication of unix servers via ACS over radius protocol can be achiveable,check out the below link client end configuration needs to be done for radius authentication
Hope that helps out your query !!

Cisco NAC, Cisco ACS, Microsoft NAP, Anti Virus

Hi,
I'm doing a research on the Cisco NAC (without the appliance) concept and I would like to ask the following:
1. Securing network access - Needed products are Cisco ACS and Cisco access devices (2960, for example). The feature needed is NAC Layer 2 IEEE 802.1x. Is this correct?
2. Forcing Windows PC to download OS patches according to company policy. Needed products are Cisco ACS, Cisco access devices, Cisco Trust Agent and Microsoft NAP (Network Access Protection)? Is there a way to do this only with Windows Server (not using NAP)?
3. Forcing Windows PCs to update Anti Virus software. Needed products are Cisco ACS, Cisco access devices, Cisco Trust Agent and Anti Virus server? Is this correct?
Please, give me some advice.
Thanks in advance,
Mladen

Thanks for the reply, but still I am a bit confiused (would you please try to answer the questions?):
1. Securing network access - Needed products are Cisco ACS and Cisco access devices (2960, for example). The feature needed is NAC Layer 2 IEEE 802.1x. Is this correct?
2. To force update of Windows patches, do I need a NAC appliance (I can only install CSACS)?
3. To force AV updates, do I need a NAC appliance (I can only install CSACS)?
I refer to
"Implementing Network Admission Control Phase One Configuration and Deployment";
"Network Admission Control Software Configuration Guide - Information About Network Admission Control".
Thanks in advance,
Mladen

Cisco ACS Server Tacacs Based on LDAP AND Source IP Possible???

Hi All,
I have used Cisco ACS tacacs for authentication based on Active Directory. Is it possible to use Active Directory as a criteria for authentication AND source IP?
For example, if someone wants to log in to a certain device... they must have correct credentials AND their IP must be sourcing from the acceptable subnet range.
Thanks!

I see your point. This will depend if the user's IP is provided in the authentication request, if this information is provided then you can use the feature called "End Station Filter". This feature is used as a Condition in the Access Policy to deny or allow access. Below are the steps:
1. Create a End Station Filter, here configure the user's IP
2. Customize your Conditions under Access Policies/Authorization to use End Station Filter
3. Define your rule with the required result
