Other-Config Check the check box to indicate that the interface use the stateful
autoconfiguration mechanism to configure parameters other than IPv6
addresses.
Clear the check box to indicate that the interface does not use the stateful
autoconfiguration mechanism to configure parameters other than IPv6
addresses.
NS Interval The ACE sends neighbor solicitation messages through ICMPv6 on the
local link to determine the IPv6 addresses of nearby nodes (hosts or
routers). You can configure the rate at which the ACE sends these
neighbor solicitation messages.
By default, the interval at which the ACE sends NS messages for DAD
default is 1000 milliseconds (msecs). To configure the interval, enter an
integer from 1000 to 2147483647.
NS Reachable Time The neighbor solicitation reachable time is the time period in
milliseconds during which a host considers the peer is reachable after a
reachability confirmation from the peer. A reachability confirmation can
include neighbor solicitation or advertisement, or any upper protocol
traffic.
By default, this time period is 0 milliseconds. To configure this time,
enter an integer from 0 to 3600000.
Retransmission time By default, the advertised retransmission time is 0 milliseconds.
To configure the retransmission time, enter an integer from 0 to
3600000.
DAD Attempts By default, the number of attempts for sending duplicate address
detection (DAD) is 1.
To configure the DAD attempts, enter an integer from 0 to 255.
RA Hop Limit By default, the hop limit that neighbors should use when originating
IPv6 packets is 64. To configure the hop limit in the IPv6 header, enter
an integer from 0 to 255.
RA Lifetime The router advertisement (RA) lifetime is the length of time that
neighboring nodes should consider the ACE as the default router before
they send RS messages again.
By default, this length of time is 1800 seconds (30 minutes). To
configure the RA lifetime, enter an integer from 0 to 9000.
RA Interval By default, the rate at which the ACE sends RA messages is 600
seconds. To configure the rate, enter an integer from 4 to 1800. This
interval must not exceed the RA lifetime.
