RADIUS does
not support Command authorization.
The command show privilege displays the current privilege level. The enable password level command can be used to set password for a particular privilege level.
Infrastructure ACL
As discussed in Chapter 2 , "Access Control," Infrastructure ACLs are applied to explicitly filter traffic destined to the device
addresses. The ACL is applied inbound on all externally facing connections (such as peering connections and customer
connections) to minimize the risk of direct infrastructure attack by explicitly permitting only authorized traffic to the
infrastructure equipment.
Note
For more details and a configuration example of Infrastructure ACLs, refer to

Interactive Access Methods
To gain access to a device for administrative purposes, you can use three basic methods: the console port, VTY ports, and the
auxiliary port, each discussed in detail in the sections that follow.
Console Port
The console port is the default access method for device management and configuration. This type of connection is used to
physically connect to the console port of a device via the TTY line 0.
