interpretation of AAA authorization

Similar Questions

• 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).

• The AAA authorization

  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

  >

  >

  > telnet 10.66.79.100

  User access audit

  User name: fred

  Password:

• I am unable to connect with GANYMEDE + connection after the addition of aaa authorization network command

  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!

• 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...

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

  RESULT:

  SWITCH #sh run int vlan 2
  Building configuration...

  Current configuration: 38 bytes
  !
  interface Vlan2
  no ip address
  end

  QUESTION:

  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).

  The Ganymede running Cisco Secure ACS4.2.0.124

  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.

• AAA authorization problem

  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.

• 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.

• AAA authorization?

  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.

• 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

• Accounting and authorization of the AAA

  Hello everyone.
  I give myself a proposed implementation of AAA on routers and switches in our environment. Can someone please help me understand the difference between.
  command option 1) aaa authorization exec and the authorization of the aaa.
  aaa accounting exec command option 2) and the aaa accounting.
  Thank you very much.

  Sent by Cisco Support technique Android app

  Hello

  command option 1) aaa authorization exec and the authorization of the aaa.
  One allows if the user has the privilege level right to enter unrestricted IOS (0,1,15) levels, you can customize it.

  The other allows different commands, a user can type and send to the device

  aaa accounting exec command option 2) and the aaa accounting.

  One represents once again when a user changes from a specific user-level (level preferred 15 or user-level Exec 1)

  Secondly it sends a message of each shipment of order based costing to box

• Order of authorization number.

  Hello.

  I use the authorization of Cisco Secure ACS 4.1 commands. This morning I put the MOTD and entered fail because my banner starts with a space.

  The set of shell commands that I use is "unmatched orders permit."

  Any idea?

  Thank you.

  Andrea

  What you feel is a known defect:

  CSCtg38468 cat4k/IOS: exec banner failed with white characters

  Symptom:

  % PARSE_RC-4-PRC_NON_COMPLIANCE:

  The error of the parser above can be seen with the traceback, when you configure a banner containing an empty character at the beginning of the line.

  Conditions:

  The problem occurs when the AAA authorization is used in conjunction with GANYMEDE +.

  Workaround solution:

  Make sure that there is no space character at the beginning of the line of the message of the banner.

  Details of the problem: try to configure exec banner with empty character at the beginning of the line failed.

  This occurs when you configure the banner via telnet/ssh exec!

  When you configure the exec banner even through the console port, all right.

  Note the white characters at the beginning of each line. When you remove those, exec banner works very well.

  Again, it was working until IOS version 12.2 (46) SG.

  Beginning with 12.2 (50) SG1 and upward, the behavior has changed.
