Thaks alot for the link.we are using tacacs only.

Is it possible for a user to be a part of more than one usergroup and client device to be part of more than one Network device group?

Hi

I forgot to add one more query

After configuring neccessary steps in ACS for command authorization ,I am not able to to get into enable mode for Priv level 1 user.(read only access).I set priv level 1 under TACACS+ settings section,Because i want to give only show access(all show commands) to certain devices

Following error recived for enable command in router

Command authorization failed.

For read& write access it is working fine.these r the configuration in router

aaa authorization config-commands

aaa authorization commands 0 default group tacacs+ local

aaa authorization commands 1 default group tacacs+ local

aaa authorization commands 15 default group tacacs+ local

Hi,

If you are using command authorization then privilage doesn't matter.

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+
