Command Usage

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.

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.

If the rapid commit option has been enabled on the switch using the

ipv6 dhcp client

rapid-commit vlan

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.

Example

Console(config)#ipv6 dhcp client rapid-commit vlan 2

Console(config)#

ipv6 dhcp restart client vlan

This command submits a DHCPv6 client request.

ipv6 dhcp restart client vlan vlan-id

vlan-id - VLAN ID, specified as a single number, a range of consecutive numbers separated
by a hyphen, or multiple numbers separated by commas. (Range: 1-4093; Maximum
