Refer to the exhibit. A user must be granted management access to the Cisco Nexus 9000 Series Switch using AAA servers. The RADIUS servers are configured to accept login requests from the same Layer…

Command authorization is a separate AAA function from authentication and is not required to meet the specific login authentication requirements for console and SSH access.

Changing the dead timer for RADIUS servers affects how long the switch waits before marking a server as unreachable, which does not directly address the requirement of using specific servers for console vs- SSH login.

Setting the RADIUS source interface is crucial because it defines the interface through which the switch sends RADIUS requests for a specific server group. This ensures that RADIUS server 1 (for console) and RADIUS server 2 (for SSH) receive requests originating from the expected interface (mgmt0 and VLAN 22 respectively), enabling proper communication and authentication, especially when servers might be filtering based on source IP.

This action directly addresses the requirement to use different RADIUS servers for different login methods. By configuring `authentication login` to specify `group RAD1` for `console` access and `group RAD2` for `remote` (SSH) access, the switch correctly directs authentication requests to the designated RADIUS server based on the login method used.

Configuring AAA accounting sends records of user activity to RADIUS servers after successful logins/actions, which is distinct from configuring how users authenticate using different servers for different access methods.
