The source IP address specified for the HWTACACS scheme.2. The source IP address specified in system view for the VPN or public network, depending onwhere the HWTACACS server resides.3. The IP address of the outbound interface.Follow these steps to specify a source IP address for all HWTACACS schemes in a VPN or thepublic network:To do… Use the command… Remarks1.
