tmnxTacPlusSourceAddress is used to configure the source address of
the TACACS+ packet. It should be a valid unicast address.
If this object is configured with the address of the router interface,
the TACACS+ client uses it while making a request to the server.
If the address is not configured or is not the address of the one of
interfaces, the source address is based on the address of the TACACS+
server. If the server address is in-band, the client uses the system
ip address as the source address. If it is out-of-band, the source
address is the address of the management interface.
tmnxRadiusSourceAddress was made obsolete in the 4.0 revision of
Alcatel-Lucent SROS series systems. The source address of the TACACS+
packet can now be set by creating a tmnxSourceIPEntry for TACACS+
application in the tmnxSourceIPTable.
