Command Syntax and Usage
prisrv
Defines the primary TACACS+ server address.
secsrv
Defines the secondary TACACS+ server address.

<1-32 character secret>
This is the shared secret between the switch and the TACACS+ server(s).

port
Enter the number of the TCP port to be configured, between 1 - 65000. The default is 49.
retries <
TACACS server retries, 1-3>
Sets the number of failed authentication requests before switching to a different TACACS+ server.
The default is 3 requests.
timeout
Sets the amount of time, in seconds, before a TACACS+ server authentication attempt is consid-
ered to have failed. The default is 5 seconds.
bckdoor disable|enable
Enables or disables the TACACS+ back door for Telnet, SSH/SCP, or HTTP/HTTPS.
Enabling this feature allows you to bypass the TACACS+ servers. It is recommended that you use
Secure Backdoor to ensure the switch is secured, because Secure Backdoor disallows access through
the back door when the TACACS+ servers are responding.
The default is disabled.
To obtain the TACACS+ backdoor password for your GbESM, contact your IBM Service and
Support line.
secbd enable|disable
Enables or disables TACACS+ secure back door access through Telnet, SSH/SCP, or HTTP/
HTTPS only when the TACACS+ servers are not responding.
This feature is recommended to permit access to the switch when the TACACS+ servers become
unresponsive. If no back door is enabled, the only way to gain access when TACACS+ servers are
unresponsive is to use the back door via the console port.
The default is disabled.
cmap enable|disable
Enables or disables TACACS+ privilege-level mapping.
The default value is disabled.
