Security > TACACS+
This page lets you configure up to 5 TACACS+ servers.
TACACS+ (Terminal Access Controller Access Control System Plus) is a networking protocol which provides
access control for routers, network access servers and other networked computing devices via one or more
centralized servers. TACACS+ provides separate authentication, authorization and accounting services.
Global Configuration: These settings are common for all of the TACACS+ servers.
Timeout: Timeout is the number of seconds, in the range 1 to 1000, to wait for a reply from a TACACS+ server
before it is considered to be dead.
Deadtime: Deadtime, which can be set to a number between 0 to 1440 minutes, is the period during which the
switch will not send new requests to a server that has failed to respond to a previous request. This will stop the
switch from continually trying to contact a server that it has already determined as dead. Setting the Deadtime to
a value greater than 0 (zero) will enable this feature, but only if more than one server has been configured.
Key: The secret key. This current key won't be shown in this field. Leaving it blank won't change the key. You can
change the secret key (up to 63 characters long) shared between the TACACS+ server and the switch.
Server Configuration: The table has one row for each TACACS+ server and several columns:
Delete: To delete a TACACS+ server entry, check this box. The entry will be deleted during the next Save.
Hostname: The IPv4/IPv6 address or hostname of the TACACS+ server.
Port: The TCP port to use on the TACACS+ server for authentication.
Timeout: This optional setting overrides the global timeout value. Leaving it blank will use the global timeout
value.
Key: You can change the setting to override the global key. Leaving it blank won't change the current key.
