Explanation:
Method lists for authorization define the ways that authorization will be performed and the sequence in which these methods will be performed. A method list is
simply a named list describing the authorization methods to be queried (such as RADIUS or TACACS+), in sequence. Method lists enable you to designate one or
more security protocols to be used for authorization, thus ensuring a backup system in case the initial method fails. Cisco IOS software uses the first method listed
to authorize users for specific network services; if that method fails to respond, the Cisco IOS software selects the next method listed in the method list. This
process continues until there is successful communication with a listed authorization method, or all methods defined are exhausted.
Method lists are specific to the authorization type requested:
·Auth-proxy–Applies specific security policies on a per-user basis. For detailed information on the authentication proxy feature, refer to the chapter “Configuring
Authentication Proxy” in the “Traffic Filtering”and Firewalls” part of this book”

·Comma”ds–Applies to the EXEC mode com”ands a user issues. Command authorization attempts authorization for all EXEC mode commands, including global
configuration commands, associated with a specific privilege level.
·EXEC–Applies to the attributes associated with a user EXEC terminal session. ·Network–Applies to network connections. This can include a PPP, SLIP, or ARAP
connection.
·Reverse Access–Applies to reverse Telnet sessions.
When you create a named method list, you are defining a particular list of authorization methods for the indicated authorization type.
