Removing hosts from the home network using the CLI

Follow these steps to remove IP addresses from the data exfiltration detection home network list.

When data exfiltration detection is enabled, the appliance monitors the egress traffic from the hosts specified in the home network list. The list is empty by default.

Prerequisites

Admin access to the SmartVision appliance.

To remove an IP address range from the data exfiltration detection homenet list:

Log in to the appliance CLI and go to configuration mode:
```
hostname > enable
hostname # configure terminal
```
Remove a range of IP addresses from the list by using the following command. Specify an IPv4 address range in classless inter-domain routing (CIDR) format (<ipAddress>/<prefix>).
```
no smartvision exfil homenet <ipAddress>/<prefix>
```
The following example removes two IPv4 address ranges from the list of hosts that the appliance monitors for data exfiltration:
```
hostname (config) # no smartvision exfil homenet 192.168.4.0/24
hostname (config) # no smartvision exfil homenet 172.16.74.0/16
```

Verify your configuration change.

hostname (config) # show smartvision config
