Configures the protected client list for the Domain Name System (DNS) cache analytics for the virtual router (VR).
| dns | Domain Name System. |

| add | Specifies adding to the protected client list. |
| delete | Specifies deleting from the protected client list. |
| protected-client | Specifies configuring the protected client list. |
| client_ip | Specifies the IPv4 network address of the protected client. |
| netmask | Specifies the IP address netmask of the protected client. |
| ipNetmask | Specifies the IP address/mask length of the protected client. |
| vr | Specifies the VR. |
| vr_name | Specifies the VR name. If not specified, the VR of the current command context is used. |
If not specified, by default the VR of the current command context is used.
Administrators can use this command to restrict the collection of DNS analytics for a protected client. When you configure the client IP subnet in the protected list, DNS queries from configured protected clients are erased from the analytics database and future queries are not stored.
The following example adds the client at IP address 192.168.3.3 on VR-Default to the protected client list:
# configure dns cache analytics add protected-client 192.168.3.3 255.255.255.255 VR-Default
or
# configure dns cache analytics add protected-client 192.168.3.3/32 VR-Default
The following example adds the subnet 192.168.3.0 on VR-Default to the protected client list:
# configure dns cache analytics add protected-client 192.168.3.0 255.255.255.0 VR-Default
or
# configure dns cache analytics add protected-client 192.168.3.0/24 VR-Default
The following example removes the client 192.168.3.3 on VR-Default from the protected client list:
# configure dns cache analytics delete protected-client 192.168.3.3 255.255.255.255 VR-Default
or
# configure dns cache analytics delete protected-client 192.168.3.3/32 VR-Default
