ipv6 dhcp client information refresh minimum

To configure the minimum acceptable refresh time of the DHCPv6 client

information on a specified interface. To remove the configured refresh time, use

the no form of this command.

ipv6 dhcp client information refresh minimum SECONDS

no ipv6 dhcp client information refresh minimum

Default Unlimited.

Command Mode Interface configuration.

Usage Guideline The ipv6 dhcp client information refresh minimum command specifies the

minimum acceptable refresh time of the DHCPv6 client information. If the server

sends an information refresh time option of less than the configured minimum

refresh time, the configured minimum refresh time will be used instead.

This command may be configured in several situations:

• In unstable environments where unexpected changes are likely to occur.

• For planned changes, including renumbering, an administrator can grad-

ually decrease the time as the planned event nears.

• Limit the amount of time before new services or servers are available to

the client, such as the addition of a new Simple Network Time Protocol

(SNTP) server or a change of address for a Domain Name System (DNS)

server.

Setting ipv6 dhcp client information refresh minimum or no ipv6 dhcp client

information refresh minimum will not enable or disable the DHCPv6 client

prefix delegation function.

Example The following example configures a maximum of 2 hours before the DHCP v6

client information will be refreshed.

Syntax Description

SECONDS The refresh time, in seconds. The minimum value that can be used is 600

seconds, and the maximum value can be 65535 seconds.
