All the CX4 series of clariion supports IPv6. Naviseccli link is provided by Ankit here.  The management ports support both IPv4 and IPv6 Internet Protocolsconcurrently. IPv4 is the default and you must provide IPv4 addresses.If your network supports IPv6, you can choose to use IPv6 withautomatic or manual configuration. For automatic configuration, youdo not need to provide any information. For manual configuration, youmust provide the global prefix and the gateway.  No both cannot be configured simultaneously as per my knowledge.  Not with both simultaneosly.  Thanks Rupal Rajwar
