Commands for Security Function Chapter 6 Commands for TACACS+
46-2
Example: Configure test as the TACACS+ server authentication key.
Switch(config)# tacacs-server key test
46.3 tacacs-server nas-ipv4
Command: tacacs-server nas-ipv4
no tacacs-server nas-ipv4
Function: Configure the source IP address of TACACS+ packet sent by the switch; the “no
tacacs-server nas-ipv4” command deletes the configuration.
Parameter: is the source IP address of TACACS+ packet, in dotted decimal notation, it
must be a valid unicast IP address.
Default: No specific source IP address for TACACS+ packet is configured, the IP address of the interface
from which the TACACS+ packets are sent is used as source IP address of TACACS+ packet.
Command Mode: Global Mode
Usage Guide: The source IP address must belongs to one of the IP interface of the switch, otherwise an
failure message of binding IP address will be returned when the switch send TACACS+ packet. We
suggest using the IP address of loopback interface as source IP address, it avoids that the packets from
TACACS+ server are dropped when the interface link-down.
Example: Configure the source ip address of TACACS+ packet as 192.168.2.254.
Switch#tacacs-server nas-ipv4 192.168.2.254
46.4 tacacs-server timeout
Command: tacacs-server timeout
no tacacs-server timeout
Function: Configure a TACACS+ server authentication timeout timer; the “no tacacs-server timeout”
command restores the default configuration.
Parameter: is the value of TACACS+ authentication timeout timer, shown in seconds and
the valid range is 1~60.
Command Mode: Global Mode
Default: 3 seconds by default.
Usage Guide: The command specifies the period the switch wait for the authentication through
TACACS+ server. When connected to the TACACS+, and after sent the authentication query data packet
to the TACACS+ server, the switch waits for the response. If no replay is received during specified period,
the authentication is considered failed.
Example: Configure the timeout timer of the tacacs+ server to 30 seconds.
Switch(config)# tacacs-server timeout 30
46.5 debug tacacs-server
