radius-server host (BNG)
To specify a RADIUS server host, use the radius-server host command in Global Configuration mode. To
delete the specified RADIUS host, use the no form of this command.
radius-server host ip-address [auth-port port-number] [acct-port port-number] [timeout seconds]
[retransmit retries] [key string]
no radius-server host ip-address [auth-port port-number] [acct-port port-number]
Syntax Description
IP address of the RADIUS server host.
IPv6 address is not supported.
ip-address
(Optional) Specifies the User Datagram Protocol (UDP) destination port for
authentication requests; the host is not used for authentication if set to 0. If unspecified,
the port number defaults to 1645.
auth-port
port-number
(Optional) Specifies the UDP destination port for accounting requests; the host is not
used for accounting if set to 0. If unspecified, the port number defaults to 1646.
acct-port
port-number
(Optional) The time interval (in seconds) that the router waits for the RADIUS server
to reply before retransmitting. This setting overrides the global value of the
radius-server timeout command. If no timeout value is specified, the global value
is used. Enter a value in the range from 1 to 1000. Default is 5.
timeout seconds
(Optional) The number of times a RADIUS request is re-sent to a server, if that server
is not responding or is responding slowly. This setting overrides the global setting of
the radius-server retransmit command. If no retransmit value is specified, the global
value is used. Enter a value in the range from 1 to 100. Default is 3.
retransmit retries
(Optional) Specifies the authentication and encryption key used between the router
and the RADIUS server. This key overrides the global setting of the radius-server
key command. If no key string is specified, the global value is used.
The key is a text string that must match the encryption key used on the RADIUS
server. Always configure the key as the last item in the radius-server host command
syntax. This is because the leading spaces are ignored, but spaces within and at the
end of the key are used. If you use spaces in the key, do not enclose the key in quotation
marks unless the quotation marks themselves are part of the key.
key string
Command Default
No RADIUS host is specified; use global radius-server command values.
