Usage Guidelines

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.

Example

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
