Command Usage
â—† DHCPv6 clients can obtain configuration parameters from a server through a
normal four-message exchange (solicit, advertise, request, reply), or through a
rapid two-message exchange (solicit, reply). The rapid-commit option must be
enabled on both client and server for the two-message exchange to be used.
â—† This command allows two-message exchange method for prefix delegation.
When enabled, DCHPv6 client requests submitted from the specified interface
will include the rapid commit option in all solicit messages.
â—† If the rapid commit option has been enabled on the switch with this command,
and on the DHCPv6 server, message exchange can be reduced from the normal
four step process to a two-step exchange of only solicit and reply messages.
