is
the source IP address of packet, in dotted

of the interface from which the packets are sent is used as source IP address
of packet.

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
packet. We suggest using the IP address of loopback interface as source IP
address, it avoids that the packets from server are dropped when the interface
link-down.

Configure the source ip address of packet as 192.168.2.254.
Switch#tacacs-server nas-ipv4 192.168.2.254
