4 Command Line Interface

authentication is attempted on the TACACS+ server. If the TACACS+ server is not available, the local user name and password is checked.

Example

Console(config)#authentication enable radius

Console(config)#

Related Commands

enable password - sets the password for changing command modes (4-28)

RADIUS Client

Remote Authentication Dial-in User Service (RADIUS) is a logon authentication protocol that uses software running on a central server to control access to RADIUS-aware devices on the network. An authentication server contains a database of multiple user name/password pairs with associated privilege levels for each user or group that require management access to a switch.

Syntax

[no] radius-server index host {host_ip_address host_alias} [auth-port auth_port] [timeout timeout] [retransmit retransmit] [key key]

•index - Allows you to specifiy up to five servers. These servers are queried in sequence until a server responds or the retransmit period expires.

•host_ip_address - IP address of server.

•host_alias - Symbolic name of server. (Maximum length: 20 characters)

•port_number - RADIUS serverUDP port used for authentication messages. (Range: 1-65535)

•timeout - Number of seconds the switch waits for a reply before resending a request. (Range: 1-65535)

•retransmit - Number of times the switch will try to authenticate logon access via the RADIUS server. (Range: 1-30)
