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

Parameters
time
: Specifies the delay time in the range of 0 to 86400 seconds.
Description
Use
ipv6 savi down-delay
to set the deletion delay time for SAVI.
Use
undo ipv6 savi down-delay
to restore the default.
By default, the deletion delay time is 30 seconds.
If a port is down for a period of time that exceeds the deletion delay time, the switch deletes the DHCPv6
snooping entries and ND snooping entries for that port.
Examples
# Set the deletion delay time for SAVI to 360 seconds.
<Sysname> system-view
[Sysname] ipv6 savi down-delay 360
ipv6 savi strict
Syntax
ipv6 savi strict
undo ipv6 savi strict
