Authentication of the AAA on switch

We are configuring 802. 1 x wired client. ISE is our AAA server. When configuring, I came across 3 commands different series

(1) RADIUS-server host auth-port 1812 acct-port 1813

Server RADIUS auth-port 1812 1813 acct-port host

the RADIUS server key

(2) RADIUS server for aaa group< radius="" group="" name="">

Server auth-port 1812 acct-port 1813

(3) aaa server RADIUS Dynamics-author

customer Server-key

Now, we have already created in step 2 aaa server group.

What is the importance of step 3. If I do not add a client by virtue of the dynamics-author, what effect this will have on the global configuration. Cost will not affect posture because of this

Thank you

Aditya

Hello Aditya-

Orders to step #3 configure the n (in your case, the switch) to accept the CoA (change permission) which is used for 802. 1 x network authentication. If you are only interested in the configuration of the switch for the administration of the system, then you don't need these commands however, if you are considering the deployment of 802. 1 x then you need them. For more information see this link:

If I reconfigure the switch to the ISE - peripheral network and give it the IP address of 10.18.4.38 (the ip of the gateway), my radius authentication tests suddenly becomes successful.

can someone clarify the situation what is happening here?

I need to be able to define multiple switches by their unique IP addresses.

Thanks for your time

Hello

The only time I saw that it was due to use a deprecated command: radius server host. There was a bug on the IOS XR platform as well.

Could you please reconfigure your order of RADIUS by using the new command: radius server? And test again?

The doc of Cisco for the new order:

The AAA authentication configuration

We have ACS server 3.1 to AAA for authentication for all routers and switches. I want each person to connect the router using its own id, password password and activate. If the ACS server is unavailable, I want to have different id, password and enable password for console and telnet access. What is the right way to do this? I also want to follow all orders entered on the router.

That's what I have:

AAA new-model

AAA authentication login default group Ganymede + local

enable AAA authentication login no_tacacs

the AAA authentication enable default group Ganymede + line

AAA authorization exec default group Ganymede + local

AAA authorization commands 15 default group Ganymede + local

AAA accounting exec default start-stop Ganymede group.

orders accounting AAA 15 by default start-stop Ganymede group.

!

username admin password 7 xxxxxxxxxxxxxxxx

!

!

Line con 0

connection of authentication no_tacacs

line to 0

line vty 0 4

password 7 xxxxxxxxxxxxxxxxxxxxxxxx

Yes, it's Joy on the right. Thank you, Renault

RADIUS authentication for the switch using ISE

Hi guys,.

Someone did he do Radius Authentication for switch cli connection using ISE?

We did it in our environment with ISE, but it is a challenge to give read-only access / Priv-1.

If some users know the enable password, they can use and earn full privilege.

Anyway to get around this other than to change the enable password?

We have thousands of switches and won't change on each of them.

If you have another method please advice.

Thank you in advance.

Well, you can set the "enable" function also be controlled via the AAA server with the following command:

AAA authentication enable... This way server AAA will be checked for authentication for the secret to activate and use the local database as a last resort

I hope this helps!

Test command of the AAA for EAP - TLS authentication for wireless users

Hi all

Can anyone suggest me the test command to verify the eap - tls authentication for the Cisco WAP's wireless.

If it's an authetication jump we can use the command to test the connection below

Radius of group aaa Testwap-01 #test [email protected] / * / o4 & yJ) NoL$ new-code %0
Trying to authenticate with the server radius group
User successfully authenticated

But eap - tls is not delivered with the password. He insists that for the user name.

We strive for remote location then test remotely before production.

If someone help pls in that if we have a command to test or debug command to test this authentication.

EAP - TLS requires a client certificate. How can you have a simple command that analysis without loading any certificate on the router/switch? It does not exist. This is why eap - tls is not considered an easy to deploy eap method: because it can go wrong on several levels.

The aaa command test performs a PAP authentication, therefore, it tests the connectivity of the base RADIUS and name of user and password.

If it works, the only thing that can break for eap - tls are certificates, as well as the radius server will be able to tell if something worng.

the AAA authentication enable default group Ganymede + activate

I implement CSACS 4.0. First of all on the client, I will apply aaa authenticatio / authorization under vty. The issure if I use the followin command

What happens if I connect via the console? I need to enter a name of user and password?

Here is my configuration

AAA new-model

accunting exec authvty

Any suggestion will be appreciated!

It should work because it is a guest message.banner whenever you try to connect (console/vty). I set it up on my router.

If you have banner motd, it will appear as well (see below). So, I have to remove it to get only the aaa banner & prompt is displayed:

************************************************************

AAA RADIUS authentication for the only user group

Hello

I use ACS3.1 and tries to use authentication radius for all network switches in my company.

Meet the im problem now is how to restrict only a user group to access the connection/exec switches? It seems that all user IDS in my acs able to telnet (user access) to the switch (using their login credentials).

I would like to limit still from telnet by using their ID except administrator group.

Counsel on how this is possible.

TKS!

The GBA, you need admin users in their own ACS group separated, leaving other users in their own group also.

Change the group that contains the users you don't want to give access to and under the heading of restricted access network (OAN), in "Group defined Network Access Restrictions", check the "Define based on IP access restrictions", choose "Rejected the call point" and enter switches in the table below (put a * in the port and address).

This prevents standard users authentication to switches. You can add all your switches in a group of network devices (NDG) to this, then you have to add that, in the section NAR rather than adding each switch individually.

Excluding the lines of Terminal Server in the AAA authentication

Hi all

Hope you can help, I'm trying to find a solution to exclude only the following line port by using the AAA authentication (ACS GANYMEDE +) on a map of Terminal Server on a Cisco 2600 router. Does anyone know how to do this, or point me in the right direction to solve?

I've included the output below:

AAA authentication login default group Ganymede + local
AAA authorization exec default group Ganymede + local
AAA accounting exec default start-stop Ganymede group.
AAA accounting network default start-stop Ganymede group.
AAA accounting default connection group power Ganymede
AAA accounting system default start-stop Ganymede group.

decoder location - XXXXXX XXXXXX BT
No banner motd
No exec-banner

transport of entry all

Is it a question of disabling the command line or using a defined group?

Thanks a lot for your help.

Jim.

Hi Jim

You may need to create another group for authentication to the and send your AAA configuration

line to 0

connection of authentication aux_auth

AAA authentication login aux_auth line

You can also configure a username local/pw and map it on the group to here...

Console and telnet would still use the configured default group, or you can specify specific groups:

Line con 0

console login authentication

line 4 vty0

vty authentication login

and specify the aaa authentication settings individually...

I hope this helps... all the best

The AAA authentication and VRF-Lite

Hello!

I encountered a strange problem, when you use authentication Radius AAA and VRF-Lite.

The setting is as follows. A/31 linknet is configured between PE and THIS (7206/g1 and C1812), where the EP sub-si is part of a MPLS VPN and VRF-Lite CE uses to maintain separate local services (where more than one VPN is used..).

Access to the this, via telnet, console etc, will be authenticated by our RADIUS servers, based on the following configuration:

--> Config start<>

AAA new-model

!

!

Group AA radius RADIUS-auth server

Server x.x.4.23 auth-port 1645 acct-port 1646

Server x.x.7.139 auth-port 1645 acct-port 1646

!

AAA authentication login default group auth radius local

enable AAA, enable authentication by default group RADIUS-auth

...

touch of 1646-Server RADIUS host x.x.4.23 auth-port 1645 acct-port

touch of 1646-Server RADIUS host x.x.7.139 auth-port 1645 acct-port

...

source-interface IP vrf 10 RADIUS

---> Config ends<>

The VRF-Lite instance is configured like this:

---> Config start<>

VRF IP-10

RD 65001:10

---> Config ends<>

Now - if I remove the configuration VRF-Lite and use global routing on the CE (which is OK for a simple vpn installation), AAA/RADIUS authentication works very well. "" When I activate transfer ip vrf "10" on the interface of the outside and inside, AAA/RADIUS service is unable to reach the two defined servers.

I compared the routing table when using VRF-Lite and global routing, and they are identical. All roads are correctly imported via BGP, and the service as a whole operates without problem, in other words, the AAA/RADIUS part is the only service does not.

It may be necessary to include a vrf-transfer command in the config of Group server as follows:

AAA radius RADIUS-auth server group

Server-private x.x.x.x auth-port 1645 acct-port

1646 key ww

IP vrf forwarding 10

Guys,

I hope someone can help me here to the problem of the AAA. I copied the configuration and debugging below. The router keeps using username/password local name even if the ACS servers are accessible and functional. To debug, it seems he keeps using the method list 'default' ignoring GANYMEDE config. Any help will be appreciated

Ganymede + accessible servers use source vlan 200. Also in the Ganymede server + can you check if the IP address for this device is configured correctly and also please check the pwd on the server and the game of this device.

As rick suggested sh Ganymede would be good as well. That would show the failures and the successes

AAA in switches routers vs (on Cisco IOS)

I have AAA with GANYMEDE + configured on a router in this way:

AAA login authentication default group Ganymede + local-case allow

the AAA authentication enable default group Ganymede + activate

Enter the same configuration on a switch (switches in general)?

What accounting? I have the same accounting configured on the router and switch?

for the switch I need to allow angling of the console of accounting services?

example:

Line con 0

accounting of the default commands 15

accounting exec failure

so, in the configured router Ihave accounting but not applied to interfaces for example) console, vty... as soon as the accounting is enabled on the router, it is automatically applied to all interfaces if I use the default method list? and is it true for switches?

Hi Nathan,

Whether router/Switch commands AAA for both work sense.

And you have "default" reason means that it will be applied on all interfaces on routers, as well as on the switch. You do not have to specify explicitly as:

Line con 0

accounting of the default commands 15

accounting exec failure

There is no need, as you say once again to search the accounting list 'default', which if we have already set up will look the same.

Terefore only commands that you specify is:

Accouting AAA commands default 0 arrhythmic group Ganymede +.

AAA accouting orders 1 by default start-stop Ganymede group.

AAA accouting orders 15 by default start-stop Ganymede group.

As a default we orders on three levels of privilege on IOS devices. Level of 0.1 and 15.

It can be useful :)

The AAA reports

Hi, need to provide an ACS reports that will include all orders captured on barrier-lights/switches/routers.

Installation successfully acs for these network devices, basic AAA is work, can connect has failed/past authentications, different levels of authentication has been correctly configured, but I see only the orders that were denied in reports, (have tested different user levels). How can I configure the AAA sign orders enterend e.g. network device admins?

Hi Ganesh, thanks for reply.

Unfortunately i am still unable to see executed commands in tacacs+ accounting report. I have all report fields enabled, configuration is the same as you suggested but still no luck. I setup shell command authorization set and can see if readonly users (which has rights to run only commands in readonly authorization set) trying to execute commands they are not authorize to run but cannot see all commands executed on the switch.

This is really important to have a record who and when initiated what commands on network devices.

Any other suggestions?

The PowerConnect 6248 switch, RAY and selected methodological issues

I think this should be simple enough, but doesn't work that way. I have multiple 6248 and a handful of other switches in PC and I'm RADIUS deployment as primary authentication mechanism. I'm going through some preliminary tests here and a simple thing is not just to work this way. Profile networklist I put RAY first of all that the method of selection and LOCAL for the second. The RADIUS user authenticates very well, but while trying to search the LOCAL user, it is rejected. I thought that if the local user is not found by DEPARTMENT policy, he is sent to the next method? I'm only using telnet for the moment method before changing the HTTP methods. Any thoughts would be appreciated. Thank you!

Could answer my own question here, but I think that the NPS server should probably 'time' or not meet the demand of the initial authentication for the local aspect until you reach? have not tested, but may do so shortly.

prepare the config for the model/tool switches

Guys,

I'm trying to find out if there is a tool to prepare config Cisco routers/switches. I'm looking to prepare the basic config with some VLANS, static IP, etc. of the AAA. Should I use GNS3 as Simulator to simulate a router and configure it to serve as a model or if there is another free light weight tool where I can test config for typo errors or something.

Thanks in advance!

If you have existing switches just the running-config and get some simple editor like Notepad and change the IP addresses and other things

Add No. SHUTDOWN on the interfaces, because by default they are not upward, and when you do a show running-config it does not appear as no. SHUTDOWN.
