To enable or disable support:
At the Switched PDU: prompt, type set tacacs,
followed by enabled or disabled and press En-
ter.
Setting the server address:
The Set TACACS Host command sets the IP
address or hostname of the server.
To set the server address:
At the Switched PDU: prompt, type set tacacs,
followed by host1 or host2 and the
server’s IP address or hostname. Press Enter.
Examples
The following command sets the primary TA-
CACS+ server address to 98.76.54.32:
Switched PDU: set tacacs host1
98.76.54.32<Enter>
The following command sets the secondary TA-
CACS+ server address to tacacs.rittal.com:
Switched PDU: set tacacs host2 ta-
cacs.rittal.com<Enter>
Setting the encryption key:
The Set TACACS Key command sets the encryp-
tion key used to encrypt all data packets between
the PDU and the server. This key
must match the key configured on the
server.
To set the encryption key:
At the Switched PDU: prompt, type set tacacs
key and press Enter.
At the Key: prompt, type an encryption
key of up to 60 alphanumeric and other typeable
characters - (ASCII 33 to 126 decimal) are al-
lowed; encryption keys are case sensitive. Press
Enter. To specify no password, press Enter.
At the Verify Key: prompt, retype the
key. Press Enter. To verify no password, press
Enter at the prompt.
Example
Switched PDU: set tacacs key<Enter>
Key: <Enter>
Verify Key: <Enter>
For security, key characters are not displayed.
Note!
A key size of zero results in no encryp-
tion being applied which may not be
supported by the server and
is not recommended for a production
environment.
Changing the TACACS port:
With TACACS support enabled, the PDU sends
TACACS requests to the default TACACS port
number 49. This port number may be changed
using the Set TACACS Port command.
To change the TACACS port:
At the Switched PDU: prompt, type set tacacs port,
followed by the port number and press Enter.
Example
The following changes the TACACS port number
to 50:
Switched PDU: set tacacs port 50<Enter>
Setting the authentication order:
The Set Authorder command sets the authentica-
tion order for remote authentication sessions.
The PDU supports two methods for authentication
order - Remote -> Local and Remote Only.
The Remote -> Local method first attempts au-
thentication with the server and if un-
successful with the local user database on the
PDU device.
The Remote Only method attempts authentication
only with the server and if unsuccess-
ful, access is denied.
Note!
With the Remote Only method, if au-
thentication fails due to a communica-
tion failure with the server
automatic authentication fallback will
occur to authenticate with the local user
data base on the PDU device.
To set the authentication order:
At the Switched PDU: prompt, type set author-
der, followed by remotelocal or remoteonly and
press Enter.
