Parameters

value: Specifies the time in centiseconds to wait for a DAD NS from a DHCPv6 client after the DHCPv6 client obtains an IP address. This argument ranges from 0 to 2147483647.

Description

Use ipv6 savi dad-preparedelay to set the time to wait for a DAD NS from a DHCPv6 client.

Use undo ipv6 savi dad-preparedelay to restore the default.

By default, the time to wait for a DAD NS from a DHCPv6 client is 100 centiseconds (1 second).

This command is used with the DHCPv6 snooping function. After DHCPv6 snooping detects that a client obtains an IPv6 address, it monitors whether the client detects IP address conflict. If DHCPv6 snooping does not receive any DAD NS from the client before the set time expires, SAVI sends a DAD NS on behalf of the client.

Examples

# Set the time to wait for a DAD NS from a DHCPv6 client to 100 seconds.
