Whitelisting

Whitelisting allows access to your RealPresence Group Series system web interface and SNMP ports
only to IP addresses you specify.
A whitelist supports up to 30 addresses (including IPv4 and IPv6 formats) and can only be configured in
the system web interface.
Note: If your IP addresses are dynamically assigned, make sure the whitelist is updated so those hosts
can connect to your system.

Add or remove IP addresses on your system whitelist.
Procedure
