User Guidelines
This command enables verification of the advertised the Managed Address
Configuration flag (or the M flag) in an RA message (see RFC4861). This flag could
be set by an attacker to force hosts to obtain addresses through a DHCPv6 server
that might not be trustworthy.

flag is 0:
switchxxxxxx(config)# ipv6 nd raguard managed-config-flag off
