User Guidelines
A maximum of five authorization method lists may be created for command
types.
Command authorization attempts authorization for all EXEC mode
commands associated with a privilege level, including global configuration
commands. Exec authorization attempts authorization when a user attempts
to enter Privileged EXEC mode.
If multiple authorization methods are listed, the switch will attempt
communication with each method in order, until successful communication
is established or all methods in the list have been tried. If authorization fails,
then the command is denied and no further attempts at authorization are
made for the user request.
The various utility commands like tftp, ping, outbound
command authorization. Applying a script is treated as a single command
apply script which also must pass authorization. Startup-config commands
applied on device boot-up are not subject to the authorization process.
