AAA Authorization help
I have configured authentication for the outside users to connect to my servers using the following sample acl
access-list 110 permit tcp any host 10.10.10.3 eq http
access-list 110 permit tcp any host 10.10.10.4 eq http
access-list 110 permit tcp any host 10.10.10.5 eq http
aaa authentication match 110 outside TACACS+
Now for authorizing them do i have to create another set of acls or can i just use the existing acls and write
aaa authorization match 110 outside TACACS+
Is there anything else i should do on the AAA-Server for authorization?
Thanks
Jason
Hi Jason,
You can use the same ACL for authorization. You will not have to do anything on ACS unless you need to push ACLs for the user.

Vivek

AAA Authorization named authorization list
Ladies and Gents,
Your help will be greatly appreciated – I am currently studying CCNP Switch AAA configuration and I work with a tacacs+ server at work butI having difficulty getting my head around the below
Cisco.com extract below
When you create a named method list, you are defining a particular list of authorization methods for the indicated authorization type.
Once defined, method lists must be applied to specific lines or interfaces before any of the defined methods will be performed. The only exception is the default method list (which is named "default"). If the aaa authorization command for a particular authorization type is issued without a named method list specified, the default method list is automatically applied to all interfaces or lines except those that have a named method list explicitly defined. (A defined method list overrides the default method list.) If no default method list is defined, local authorization takes place by default.
My question is how do you define the Named Method List i.e. the none-default method list?
I don't mean the cisco switch config but how the list is created, is this on the tacacs+ server and the referred to in the CLI?
Any help would be much appreciated as I have read over tons of documents and I can’t see how this is created
Thanks in advance
DavidHi David,
An example of a named AAA list might look something like this:
aaa authorization exec TacExec group AAASrv local
In the example above, I've created a AAA authorization list for controlling shell exec sessions called "TacExec", which will check the remote AAA servers in the group "AAASrv" first; if the device receives no response from the remote servers, it will then atempt to validate the credentials via the local user database. Please remember that a deny response from the AAA server is not the same as no reposonse, the device will only check the local user database if an only if it recieves nothing back from the TACACS query.
Of course, before you create this method list, you need to define the TACACS servers via the "tacacs-server" command, and then add those servers to the group via the "aaa group server" command.
Below is a cut and paste from the AAA section on one of my devices:
aaa new-model
ip tacacs source-interface
tacacs-server host 10.x.x.x key 7
tacacs-server host 10.x.x.y key 7
aaa group server tacacs+ TacSrvGrp
server 10.x.x.x
server 10.x.x.y
aaa authentication login default local
aaa authentication login TacLogin group TacSrvGrp local
aaa authorization console
aaa authorization config-commands
aaa authorization exec default local
aaa authorization exec TacAuth group TacSrvGrp local
aaa authorization commands 0 default local
aaa authorization commands 0 TacCommands0 group TacSrvGrp local
aaa authorization commands 1 default local
aaa authorization commands 1 TacCommands1 group TacSrvGrp local
aaa authorization commands 15 default local
aaa authorization commands 15 TacCommands15 group TacSrvGrp local
aaa accounting exec default start-stop group TacSrvGrp
aaa accounting commands 15 default start-stop group TacSrvGrp
aaa session-id common
Notice that for the various authentication and authorization parameters, there is a named method list as well as a default method list. As per Cisco's documentation, a aaa method list called default (that you explicitly define) will apply to all input methods (con, aux, vty, etc) unless you set a named method list on the particular input line (see below):
line con 0
exec-timeout 5 0
line aux 0
exec-timeout 5 0
line vty 0 4
exec-timeout 15 0
authorization commands 0 TacCommands0
authorization commands 1 TacCommands1
authorization commands 15 TacCommands15
authorization exec TacAuth
login authentication TacLogin
transport input ssh
For the console and aux inputs, I only ever want to use local credentials for AAA purposes (ie: If I have to connect on an out-of-band interface, something is potentially wrong with the network connectivity), however for the VTY lines (SSH sessions in this instance), I always want to use the TACACS servers first, with local user credentials as a fallback mechanism.
One thing you need to be VERY mindful of when configuring your devices for AAA is the order of the commands that are entered. It is a relatively simple matter to lock yourself out from the device management if you don't pay close attention to the specific order that the commands are entered. Typically, I will first do a "show user" just to find out which VTY line that I'm connected on, and when I assign the named AAA method lists to the VTY lines, I normally leave the line that I'm on at the default (local), then I open a second session to the device, authenticate using my TACACS credentials, and complete the config on the remaining VTY line.
Keep in mind that there are some other parameters that you can define at the tacacs-server level (timeout value is a good one to look at) which you can use to enhance the AAA performance somewhat.
Hope this helps! -
AAA Authorization Using Local Database
Hi Guys,
I'm planning to use AAA authorization using local database. I have read already about it, I have configured the AAA new-model command and I have setup user's already. But I'm stuck at the part where I will already give certain user access to certain commands using local database. Hope you can help on this.
FYI: I know using ACS/TACACS+/RADIUS is much more easy and powerful but my company will most likely only use local database.For allowing limited read only access , use this example,
We need these commands on the switch
Switch(config)#do sh run | in priv
username admin privilege 15 password 0 cisco123!
username test privilege 0 password 0 cisco
privilege exec level 0 show ip interface brief
privilege exec level 0 show ip interface
privilege exec level 0 show interface
privilege exec level 0 show switch
No need for user to login to enable mode. All priv 0 commands are now there in the user mode. See below
User Access Verification
Username: test
Password:

Command execution get very slow when AAA Authorization enable on ASR 1006
Without Authorization , I am able work smoothly with just click on ASR ...., But Once I enable Authorization it takes many secs to move to other command exampe ( If i hit config t or int gi1/0/1 , it take time to move to next command level) ...
These Authorization issue I am facing only on ASR and for Other Cisco Switches and Router its working fine wiith just a click.
Did any one face such issue , and how it is fix ...

You can try to debug the issue by referring to the command reference guide....i.e. debug tacacs...you can also try to telnet to both ip address to port 49 to see if the connection opens, in order to rule out issues where a firewall or routing to one of the tacacs servers is failing. I also noticed you have the shared secret and tacacs server defined for one of the servers, is the sam present for the other server that is in the server group?

Hi,
i have the following config :
aaa new-model
aaa authentication login NO_LOGIN none
aaa authentication login ADMINS group radius local
aaa authentication login CONSOLE group radius local
aaa authorization exec NO_AUTHOR none
aaa authorization exec ADMINS group radius local
aaa authorization exec CONSOLE group radius local

authorization exec ADMINS
logging synchronous
login authentication ADMINS
line vty 5 15
password 7 060506324F41
authorization exec ADMINS
logging synchronous
login authentication ADMINS
When i am tryin gto login to the switch from vty line i come directly to privillage mode, but when loging to console port i come to the exec mode (privilage 1) and i cant go further to the user privillage mode . each time i have to type a password (i type the enable one) and my access is denied.
when issuing the command # aaa authorization console (using telnet from other switch)
the problem is solved.
Can someone please explain why is this happening? i think after logging in with local account (with privillage 15) from console port i should get directly to privilage mode, or am i wrong ?aaa authorization console is a hidden command. We have to execute this command to enable authorization for console line. If you create a method list "aaa authorization exec CONSOLE group radius local" for console and try to apply it on line console 0, it will throw an error that without "aaa authorization console" all authorization commands for console is useless. You have to first enable authorization for console with the help of aaa authorization console.

AAA authorization and accounting
Hello everyone.
I am given a project to implement AAA on routers and switches in our environment. Can some one please help me out in understanding the difference between,
1) aaa authorization exec and aaa authorization command option.
2) aaa accounting exec and aaa accounting command option.
Many thanks.
Sent from Cisco Technical Support Android AppHello,
1) aaa authorization exec and aaa authorization command option.
The first one authorizes if the user has the right privilege level to enter to one of the IOS priviliege levels (0,1,15) you can customize this.
The second one authorizes the different commands a user can type and send to the device
2) aaa accounting exec and aaa accounting command option.
The first one again accounts when a users enters a specific user-level (Privileged level 15 or Exec user-level 1)
Second one sends an accounting message per each command send to the box
Check my blog at http:laguiadelnetworking.com for further information.

I have faced a problem regarding AAA line:
aaa authorization exec default group tacacs+ local
if i add this line in my cisco 4948 switch running on 122-46.SG.. The next time i telnet to the switch i get an automatic restart of the switch and all configs are lost.
IOS used:

AAA authorization show run in priv 7
Hi,Any one can help...
I have set up AAA on my network.
aaa authentication login default group tacacs+ group security local
aaa authorization exec default group tacacs+ group security local
aaa accounting exec default start-stop group tacacs+ group security
tacacs-server host x.x.x.x
tacacs-server directed-request
tacacs-server key 7 xyz
I want set prvilige on group basis.
I have created a group called test in ACS server and set comnand authorization on pergroup basis
& added show command with permit running-config as arguments.
My objective is give the user of test group priv level 7 but they can use show running-config.
Any help?
thanks in advanceHi,
Thanks for your reply.It's nearly the exact what I wanted.However show running-config only shows like these
7206a#sh run
Building configuration...
Current configuration : 53 bytes
boot-start-marker
boot-end-marker
end
However #Show config
shows the proper running-config
Thanks -
Command confusion - aaa authorization config-commands
I created a new Shell Command Authorization Set within ACS to only allow a port to be configured for a voice VLAN.
>> Shell Command Authorization Sets
Name: Restricted_Voice
Description: Configure port voice vlan only.
Unmatched Commands: Deny
Add: enable
Add: configure / permit terminal <cr>
Add: interface / permit Gi*
Add: interface / permit Fa*
Add: switchport / permit voice vlan *
My switch configuration has the following aaa authorization related lines:
aaa authorization commands 1 default group tacacs+ if-authenticated
aaa authorization commands 15 default group tacacs+ if-authenticated
When I tested the Shell Set, I noticed that all (config) mode commands were allowed (ie description, hostname). It was only after I added "aaa authorization config-commands" to the switch configuration did my Shell Set began working as I expected it to be.
I went and read up the command reference for "aaa authorization config-commands" in
http://www.cisco.com/en/US/docs/ios/11_3/security/command/reference/sr_auth.html#wp3587.
My comprehension of the command is that by just issuing ' aaa authorization commands 15 ....' this command encompasses the checking of config mode commands and that I did not need to add the stand-alone "aaa authorization config-commands" statement. But clearly, from my testing, I needed the extra statement.
It looks like I resolved my issue and need to add the new statement to all my switches, I'm wondering if someone can help clarify the usage guidelines for me. I'm I one of the few or only one that misinterpreted these "aaa authorization" commands?Hi Axa,
I have a similar setup and have full Exec Level permissions using only aaa authorization commands level method
The below is taken from cisco.com and explains that you should not require the
aaa authorization config-commands unless you have at some point used the no aaa authorization config-commands command to prevent configuration commands from the Exec User
This in essense is a hidden configured default i.e.you switch on auth for config-commands automatically when you use the aaa authorization commands level method command!
From Cisco.com (I have underlined the key points)
aaa authorization config-commands
To disable AAA configuration command authorization in the EXEC mode, use the no form of the aaa authorization config-commands global configuration command. Use the standard form of this command to reestablish the default created when the aaa authorization commands level method1 command was issued.
aaa authorization config-commands
no aaa authorization config-commands
Syntax Description
This command has no arguments or keywords.
Defaults
After the aaa authorization commands level method has been issued, this command is enabled by default—meaning that all configuration commands in the EXEC mode will be authorized.
Usage Guidelines
If aaa authorization commands level method is enabled, all commands, including configuration commands, are authorized by AAA using the method specified. Because there are configuration commands that are identical to some EXEC-level commands, there can be some confusion in the authorization process. Using no aaa authorization config-commands stops the network access server from attempting configuration command authorization.
After the no form of this command has been entered, AAA authorization of configuration commands is completely disabled. Care should be taken before entering the no form of this command because it potentially reduces the amount of administrative control on configuration commands.
Use the aaa authorization config-commands command if, after using the no form of this command, you need to reestablish the default set by the aaa authorization commands level method command.
Examples
The following example specifies that TACACS+ authorization is run for level 15 commands and that AAA authorization of configuration commands is disabled:
aaa new-model
aaa authorization command 15 tacacs+ none
no aaa authorization config-commands -
AAA Authorization + Switch Cluster = Fail?
Hi, I had a Switch Cluster running with local authentication and authorization just fine (with aaa new-model). It's a stack of 3750-Xs and several 2960s, they've all been configured more or less the same way with a configuration template.
I added AAA authentication and authorization and I can still reach each of the switches individually, but when I try to rcommand "x" from the cluster commander, I get:
#rcommand 2
% Authorization failed.
One of the 2960s is a stack and when I run rcommand to that switch I get something different:
#rcommand 1
EBMIASWF1LB-01 tty1 is now available
Press RETURN to get started.
All other 2960s give me "% Authorization failed."
3750s are running:
Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 12.2(55)SE3, RELEASE SOFTWARE (fc1)

Debug on 2960S (stack) is the same.
The radius server is a Microsoft NPS (IAS on 2012) and all switches have AAA configured the same:
NPS is sending these AV Pairs:
shell:priv-lvl=15
Service-Type = Administrative
Service-Type = NAS-Prompt-User
Switches are configured like this:
aaa new-model
aaa group server radius RadiusAAA
server x.x.x.x auth-port 1645 acct-port 1646
server y.y.y.y auth-port 1645 acct-port 1646
ip radius source-interface VlanXX
deadtime 1
aaa authentication login default group RadiusAAA local
aaa authorization exec default group RadiusAAA if-authenticated local
aaa session-id common
! etc etc
radius-server host x.x.x.x auth-port 1645 acct-port 1646 key 7 <radius key>
radius-server host y.y.y.y auth-port 1645 acct-port 1646 key 7 <radius key>
radius-server deadtime 1
I've also tried moving around the
aaa authorization exec default group RadiusAAA if-authenticated local
to:
aaa authorization exec default group RadiusAAA local if-authenticated
But the results are the same... Telnet and SSH work great, but I'd like for the cluster to keep working!
Any ideas?
Thanks in advance for your help, I've spent a lot of time on this, and I don't even know if it's supported!

Hi,
Configured the switch for the AAA authentication it's getting authenticated but it's failing for authentication.
When connected to console it worked- Authenticated and then supplied the enable password.
When telneted : it says "access approved" and "authorization failed"
Relevant switch configuration is as follows and also debug of aaa authorization.

Do we need to change anything on Radius server or can we change the authorization preference to local and then to radius.
Please share the experience.
Thanks in advance,
SubodhHi Subodh,
I understand that you are trying to use command authorization using RADIUS.
aaa authorization commands 15 default group radius if-authenticated local
Command authorization is not supported in RADIUS. RADIUS does not allow users to control which commands can be executed on a router and which cannot.
Please refer the following link:
http://www.cisco.com/en/US/tech/tk59/technologies_tech_note09186a0080094e99.shtml
You need to use TACACS+ for configuring command authorization for IOS and PIX/ASA.
Regards,
Karthik Chandran
