retransmit 4
Success.
DAS-3626:admin#
DAS-3600 Series Ethernet over VDSL Switch CLI Reference Manual
Used to configure a user-defined authentication server host.
config authen server_host <ipaddr> protocol [tacacs | xtacacs | tacacs+ | radius] {port
<int 1-65535> | key [<key_string 254> | none] | timeout <int 1-255> | retransmit < 1-
255>}
This command will configure a user-defined authentication server host for the
TACACS/XTACACS/TACACS+/RADIUS security protocols on the Switch. When a user
attempts to access the Switch with the authentication protocol enabled, the Switch will send
authentication packets to a remote TACACS/XTACACS/TACACS+/RADIUS server host on a
remote host. The TACACS/XTACACS/TACACS+/RADIUS server host will then verify or deny
the request and return the appropriate message to the Switch. More than one authentication
protocol can be run on the same physical server host but, remember that
TACACS/XTACACS/TACACS+/RADIUS are separate entities and are not compatible with
each other. The maximum supported number of server hosts is 16.
server_host <ipaddr> − The IP address of the remote server host the user wishes to alter.
protocol – The protocol used by the server host. The user may choose one of the following:
•
tacacs – Enter this parameter if the server host utilizes the TACACS protocol.
•
xtacacs − Enter this parameter if the server host utilizes the XTACACS protocol.
•
tacacs+ − Enter this parameter if the server host utilizes the TACACS+ protocol.
•
radius − Enter this parameter if the server host utilizes the RADIUS protocol.
port <int 1-65535> − Enter a number between 1 and 65535 to define the virtual port number
of the authentication protocol on a server host. The default port number is 49 for
TACACS/XTACACS/TACACS+ servers and 1812 and 1813 for RADIUS servers but the user
may set a unique port number for higher security.
key <key_string 254> − Authentication key to be shared with a configured TACACS+ or
RADIUS server only. Specify an alphanumeric string up to 254 characters or choose none.
timeout <int 1-255> − Enter the time in seconds the Switch will wait for the server host to
reply to an authentication request. The default value is 5 seconds.
retransmit <int 1-255> − Enter the value in the retransmit field to change how many times the
device will resend an authentication request when the server does not respond. This field is
inoperable for the TACACS+ protocol.
Only Administrator-level users can issue this command.
