Use this command in Global Configuration mode to configure the source interface (Source IP address) for TACACS+ server configuration. The selected source-interface IP address is used for filling the IP header of management protocol packets. This allows security devices (firewalls) to identify the source packets coming from the specific switch.
If a source-interface is not specified, the primary IP address of the originating (outbound) interface is used as the source address.
| Format | tacacs-server source-interface {unit/slot/port| loopback loopback-id | vlan vlan-id} |
| Mode | Global Config |
| Parameter | Description |
|---|---|
| unit/slot/port | The unit identifier assigned to the switch, in unit/slot/port format. |
| loopback-id | The loopback interface. The range of the loopback ID is 0 to 7. |
| vlan-id | Configures the VLAN interface to use as the source IP address. The range of the VLAN ID is 1 to 4093. |
The following shows an example of the command.
(Config)#tacacs-server source-interface loopback 0 (Config)#tacacs-server source-interface 1/0/1 (Config)#no tacacs-server source-interface
