Configuring TACACS/ security
4
AAA security for commands pasted Into the running configuration
If AAA security is enabled on the device, commands pasted into the running configuration are
subject to the same AAA operations as if they were entered manually.
When you paste commands into the running configuration, and AAA command authorization or
accounting is configured on the device, AAA operations are performed on the pasted commands.
The AAA operations are performed before the commands are actually added to the running
configuration. The server performing the AAA operations should be reachable when you paste the
commands into the running configuration file. If the device determines that a pasted command is
invalid, AAA operations are halted on the remaining commands. The remaining commands may not
be executed if command authorization is configured.
TACACS/ configuration considerations
Consider the following before you configure TACACS/:
•
You must deploy at least one TACACS/ server in your network.
•
The device supports authentication using up to eight TACACS/ servers. The device
tries to use the servers in the order you add them to the device’s configuration.
•
You can select only one primary authentication method for each type of access to a device (CLI
through Telnet, CLI Privileged EXEC and CONFIG levels). For example, you can select
as the primary authentication method for Telnet CLI access, but you cannot also select RADIUS
authentication as a primary method for the same type of access. However, you can configure
backup authentication methods for each access type.
•
You can configure the Brocade device to authenticate using a TACACS or server, not
both.
