Usage Guidelines

The information-refresh command is used on DHCPv6 servers. When the DHCPv6 server assigns configuration parameters such as the DNS, NIS, and SNTP server addresses to the DHCPv6 clients through stateless autoconfiguration, you can use the information-refresh command to configure the time for updating these configuration parameters.

If a Huawei device functions as a DHCPv6 client and the time configured using the information-refresh command on the DHCPv6 server is larger than three days (259200 seconds), the time for updating DHCPv6 client configuration information is three days. If the time configured using the information-refresh command on the DHCPv6 server is less than or equal to three days, the time for updating DHCPv6 client configuration information is the actually configured value.

Example

# Set the time for updating configuration parameters assigned to clients to 10000s in the address pool pool1.

<HUAWEI> system-view
[HUAWEI] dhcpv6 pool pool1
