User Guidelines
The ipv6 dhcp client information refresh minimum command specifies the
minimum acceptable information refresh time. 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 the following situations:
• In unstable environments where unexpected changes are likely to occur.
• For planned changes, including renumbering. An administrator can
gradually 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 of a Domain Name System (DNS)
server.
If you configure the infinite keyword client never refreshes the information.
Example
The following example configures an upper limit of 2 days:
console(config)# interface vlan 100
console(config-if)# ipv6 dhcp client stateless
console(config-if)# ipv6 dhcp client information refresh 172800
console(config-if)# exit
ipv6 dhcp duid-en
Use the ipv6 dhcp duid-en command in Global Configuration mode to set
the Vendor Based on Enterprise Number DHVPv6 Unique Identified (DUID-
EN) format.
To return to the default value, use the no form of this command.
Syntax
ipv6 dhcp duid-en enterprise-number identifier
