xStack DGS-3400 Series Layer 2 Gigabit Managed Switch CLI Manual
Used to configure a user-defined authentication server host.
create 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.
