AAA authorization commands
Hi all
Probably, I'll ask a stupid question but I am really confused about the purpose of the "x by default local aaa authorization commands" command. I understand that if this command is configured, it allows each order of this level, but in my experience, this command does nothing. The result is the same whether or not it is configured.
Here is my config part aaa
cisco cisco username privilege 15 secret
AAA new-model
AAA authentication login default local activate
AAA authorization exec default local authenticated by FIS
AAA authorization commands 15 local default authenticated by FIS
Now if I keep the last command or remove, user name "cisco" is able to use each command level 15 so my question is, why would I bother to configure this command?
Would really appreciate your quick response

Hi Charlotte,.
According to my understanding of the database of the local user you don't need to have permission from aaa in the network device... If you use any Ganymede + / Radius authentication servers, then it will be more efficient, you can set an attributes to the user profile and through which you can play the config access level users at certain level...
When it is with a local database, to approval based on the level of privileage we set locally on the device and he never looks for aaa... reference local authorization is limited and more that it is limited to sets of levels of privileage on the specific profile...
You can go through the below document mentioned for your apprenticeship on aaa...

AAA authorization command console
Hello
I don't really understand the need of the command ""console permission aaa "."
In fact we often set up these lines, which I already ar Editions by default VTY, Console, etc... :
AAA authorization exec default group Ganymede + authenticated if
AAA authorization commands 15 default group Ganymede + authenticated if
Am I wrong? Or these lines only apply to the VTY linse?
Thank you in advance
In the IOS default Cisco does not permit on the console. When you configure aaa authorization, it is applied to vty but not to the console. Basically, it's to make it harder for lock you to in the router or switch. If you want permission to apply on the console then you must explicitly configure (and be very very careful that it is configured correctly, or you can wind up being locked out of the router - think especially how it will work when you can't get to the external aaa server that normally makes the authorization).

AAA authorization fails, but still command is executed...
Hello world
I've implemented the authorization and he basically works. The user can only use a limited set of commands (show int status, conf t interface ethernet, gigabitethernet interface, interface fastethernet, closed, non-stop).
Now, I'm trying to configure a loopback or interface Vlan, which should not be allowed.

As you can see the answer of the Ganymede is a "FAILURE", but still the command is executed.
RESULT:

endQUESTION:
I don't understand what the problem... Since I get a Ganymede Server FAILURE I guess that the configuration of this side is fine.
But why the button ignore a FAILURE, always run the command? Same problem exists with the loopback Interface.
Is it just me not the basic concept of AAA understandig or is it another problem?
The switch is a Cisco WS-C3750-24TS (running c3750-ipbasek9 - mz.122 - 50.SE2.bin).

Hi Tom,
It's CSCtd49491 : GANYMEDE authorization failed-command for the configuration of the interface.
The bug is currently in a closed state, which means that the "bug report is valid, but a conscious decision accomplished not remedy all or all outputs."
As far as I know, the impact is rather limited, given that the interface that is created has no effect unless the vlan exists, and even in this case, the effect is minimal since it cannot be configured.
You can open a TAC case or work with your account team to get the bug if it is still a matter of concern but has reopened.

interpretation of AAA authorization
Hello..
Is this a correct interpretation on aaa authorization?
If I want to allow some commands or a certain privilege I use the following example
AAA authorization command 7 Group Ganymede
No authorization from aaa config-commands
If you want to allow all commands, you must use the following:
AAA authorization config-commands
allow all orders except the configuration commands that we type in the configuration mode:
Router (config) #.
Configure a Terminal command is a command to exec level and should still be allowed in the command define the AAA server.
Even if you are runnning access to level 15 and you turn on command authorizarion using a RADIUS AAA server on this level 15, all the commands you type will be checked at the server level to see if they were authorized or not.

I have the following Setup on my way...
AAA new-model
AAA authentication login default group Ganymede + local
authentication connecting line CONSOLE of AAA.
AAA authorization config-commands
AAA authorization exec default group Ganymede + local
AAA authorization commands 1 default group Ganymede + authenticated if
AAA authorization commands by default 10 group Ganymede + authenticated if
AAA authorization commands 15 default group Ganymede + authenticated if
The problem is that when I log into the switch through the console port and enter these commands in, I instantly "Command authorization failed" on all orders get there. It's mind-boggling because there is no possible way that the switch is in talks with my Cisco ACS. I have not yet put in the radius-server key. I have to restart the box every time. What Miss me?
Thank you for your time. I use IOS Version 12.2 (25) SEB4.

Hello
I test an aaa authentication switch when it does not communicate to ISE, and I found a strange behaviour. After that I added the aaa accounting and authorization authentication controls and reloaded the switch I was not able to connect to the switch with the GANYMEDE login
The switch continued in cycles showing the banner give 3 times authentication failure message and then the cycle begins with the failed, banner and sign message
I removed the aaa authorization network command and I reloaded the switch and I was able to connect successfully.
could someone help me with this problem.
Hi Nitesh-
This command (... aaa authorization network) has nothing to do with the admin authorization on the n basis (in this case, the switch). This command applies to the network connections such as PPP, SLIP, etc.
In addition, aaa authorization can be performed by Ray and not only GANYMEDE +. RADIUS is not too powerful and you can provide authorization command sets but you can always return roles and different levels of privilege.
Have you tested the above configuration syntax? I did and it works as expected!
Thank you for evaluating useful messages!

Im trying to configure the authentication of AAA using username privililege password 15 xxxx xxxxx. I would like to make sure he users with the privilege level 15 go straight to activate the mode, and users with level 1 prvilege will go directly to the router > read-only. Currently the conly orders I typed are user name
xxx xxxx privilege 15 password
AAA new-model
Do I need to configure anything else. I tried to put the privilege under int vty level but then all users mode privilege. I want to only use AAA I don't want to set up a server radius or teacs to have3. Thanks in advance.
To use privilege levels, you need to set the authorization and authentication. The following should do the trick for you:
username cisco password 0 privilege 15 glenn
username fred privilege 1 0 password cisco
!
AAA new-model
AAA authentication login default local
AAA authorization exec default local
Now if I connect:
> telnet 10.66.79.100
User access audit
Username: glenn
Password:
Router #sho priv
Current privilege level is 15
Router #q

Design of the AAA authorization
I'm setting up several switches and routers for GANYMEDE with ACS. I have a need to access three levels, groups are the following:
1. normally read only access.
2. the full access except config t.
3. full access.
What would be the best way to achieve this, I see that if I create on GBA Shell command authorization sets, I can set up a group 1 and group 3. But I will be able to group 2? Is there a way to enable all, but explicitly block a single command? As a result of this page: http://www.cisco.com/en/US/products/sw/secursw/ps2086/products_configuration_example09186a00808d9138.shtml leads me to believe that the capacity may exist, but I have no way to confirm for the moment.
Please see the attachment.
After implementing user will be able to do anything except config t.
Kind regards

AAA authorization and control logging show
Hello guys,.
I am running IOS 15 on some routers and using ACS version 5.3.0.40.5 for authentication and authorization.
I would like to have a group of users to not be able to access the configuration mode but deliver all show commands.
However, the show logging command doesn't seem to work in user mode.
Ideas or workarounds are welcome.
Thanks in advance.

Free RADIUS for the AAA authorization
Hello
Is there a Free\OpenSource RADIUS implementation that would work with permission of AAA Cisco and Accoutning features?
I don't know if FreeRadius would be authorized to do?
Thank you------Naman
Try freeRADIUS (www.freeradius.org).
It can manage all of the Cert-oriented Basic for EAP authentication.
Good luck

What happens with authorization if a radius server verifies that the authentication breaks down? I have the possibility of premises in authentication, so if I have the possibility of local authorisation, it automatically runs the same account I'm logged in to? I'm afraid that if I let it, I won't be able to get into my router if my radius server is down.
-John
Yes, just as local authentication as a backup, you can have a local authorization as a backup (and it's also a good idea!).
Hope that helps.

Problem with shell command authorization
I came across this issue with ACS 3.1 and 3.2 of the ACS
A shell command authorization set is created under the profile shared with the following components:
Unmatched orders: refuse
Permit of unmatched Args: UNCHECKED
The order authorized is 'show' with the Arg "worm permit", "allow the interface" and "allowed to run.
This permission set is then applied to the group, under the option "Assign a Shell command authorization on any device on the network."
Select this group option is set to 'Max privilege for any customer of AAA, level 15.
This configuration is then tested against two IOS switches, with orders from aaa as follows:
AAA new-model
AAA authentication login default group Ganymede + local
the AAA authentication enable default group Ganymede + activate
AAA authorization exec default group Ganymede + local
AAA authorization commands 15 default group Ganymede + local
The problem I have is that when a user who is part of this group connects, it can issue commands such as see the worm, see the race and show int just as I would expect. Any command that does not begin with a show... is denied. However, other show commands that do not appear in the arguments of will work, so that some don't. For example, "show arp" and "vlan" worked, while "show accountants ' and 'buffer' does not. What Miss me?
commands that work without explicitly set them are of privilege more low level 15... for example; "show arp" is a command of Priv-1, so it is execuatbel without permission of command as you do not permission to order for private-1.
Router > sh priv
Current privilege level is 1

Hi all
I'm having a problem with the Shell command authorization. I have a user that I just want to be able to display the configuration of installation, it is for the auto config to archives on an hourly basis.
I have configuered the device with the following orders of aaa:
AAA new-model
AAA group Ganymede Server + ACS
AAA authentication login default group ACS
/NOAUTH AAA authentication login no
AAA authorization config-commands
AAA authorization exec default group Ganymede + group ACS
/NOAUTH AAA authorization exec no
AAA authorization commands 15 default ACS group
AAA authorization commands 15 /NOAUTH no
AAA accounting command 15 arrhythmic default group ACS
The static account I have set up ok logs and can show config etc. Access to the conf t is disabled, which is good, but for some reason, it can run any command show rather than just who is this all I welcomed in the Shell command authorization.
Unmatched command is defined for refuse and allowed unparalleled arguments are not checked.
ACS is 3.3 2 and switch I tested running 12.1 (9) EA1
Any ideas?
Most of 'show' command are level 1 controls. You can check this by logging in as a normal user, issue a private "sho" to make sure that you are at level 1, and then type 'sho ip road', "sho ver", etc., you will see that all work fine.
Your AAA commands say only the switch to allow level 15 commands, so when you do a "sho ver" or similar this order will not be sent offshore to the ACS server for authorization.
If you add the following:
AAA authorization commands 1 default ACS group
so, what do you have to fix, but be careful because it is easy to lock you out of power mode enable (add 'enable' in your command set too).
You should also noticed all those who 'show' commands were not their statement in detail either, because you have enabled also only accounting for level 15 commands.

Specific shell - ACS command authorization / GANYMEDE + on 2900XL
Hello all-
I was struggling with a particular issue here. I am running ACS 3.2 and tries to implement secure access to my switch. I have 'students' of my University I want to leave running specific functions, i.e. change the vlan port and write in memory, etc.
I created with success the piece of the authorization, and my test account can connect. I have successfully assigned a privilege level of 7 also, that gives me a look of default base rights. Accountants strives also, indicating connections and commands me to come home.
I want to do is use ACS to allow a particular group of controls, so I can change if needed in one place (ACS) and I not touch + 400 devices. ACS says can be done, but it doesn't seem to work. I created a Shell command group and specified commands, no luck. Even if I change the 'unmatched orders' rocking 'allow' (which should allow all orders, right?) it does not yet allow all orders. I added the Shell command group for the group, of which students are members...
My AAA commands are as follows:
AAA new-model
AAA of default login authentication group local Ganymede +.
Group AAA authorization exec default local Ganymede +.
AAA authorization commands by default 7 Group Ganymede +.
AAA accounting exec default start-stop Ganymede group.
orders accounting AAA 7 by default start-stop Ganymede group.
orders accounting AAA 15 by default start-stop Ganymede group.
AAA accounting system default start-stop Ganymede group.
Any ideas? Any thoughts?
Thank you!
Michael
QU.edu
Michael,
You perform permission to order order that exist with a privilege level of 7. By default, the configuration commands have a privilege to 15. There are two ways you can go about solving this problem. The first would be to authorization of installation for level 15 command. The second would be to change the privilege level of the commands that you want your students to be able to run level 15 at level 7. This can be done with the command of privilege. Here is a link that shows the use of the technology locally within the unit. http://www.Cisco.com/warp/public/480/Priv.html
I don't know if the ACS can push the configuration of the device on a per user basis, so the first option may be your best bet. Be sure to allow access to all controls for yourself.
