The default is 3 requests.
timeout <TACACS server timeout seconds, 4-15>

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.
