DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch
(ms)
Solicitation packets to be sent out over the local network. This is used to discover IPv6
neighbors on the local link. The user may select a time between
0
and
65535
milliseconds. Very fast intervals, represented by a low number, are not recommended for
this field.
Hop Limit
This field sets the number of nodes that this Router Advertisement packet will pass before
being dropped. This number is set to depreciate by one after every node it reaches and
will be dropped once the Hop Limit reaches 0. The user may set the Hop Limit between
0
and
255
. The default value is
64
.
Prefix Options
Prefix
Use this field to set a prefix for Global Unicast IPv6 addresses to be assigned to other
nodes on the link-local network. This prefix is carried in the Router Advertisement
message to be shared on the link-local network. The user must first have a Global
Unicast Address set for the Switch.
Preferred Life Time
This field states the time that this prefix is advertised as being preferred on the link local
network, when using stateless address configuration. The user may configure a time
between
0
and
4294967295
milliseconds, with a default setting of
604800
milliseconds.
Valid Life Time
This field states the time that this prefix is advertised as valid on the link local network,
when using stateless address configuration. The user may configure a time between
0
and
4294967295
milliseconds, a default setting of
2592000
milliseconds.
On Link Flag
Setting this field to
Enabled
will denote, within the IPv6 packet, that the IPv6 prefix
configured here is assigned to this link-local network. Once traffic has been successfully
sent to these nodes with this specific IPv6 prefix, the nodes will be considered reachable
on the link-local network.
Autonomous Flag
Setting this field to
Enabled
will denote that
this prefix may be used to autoconfigure IPv6
addresses on the link-local network.
Router Advertisement Settings
RA Router
Advertisement
Use this pull-down menu to enable or disable the switch as being capable of accepting
solicitation from a neighbor, and thus becoming an IPv6 neighbor. Once enabled, this
Switch is now capable of producing Router Advertisement messages to be returned to
querying neighbors.
RA Router Life Time
(sec)
This time represents the validity of this interface to be the default router for the link-local
network. A value of 0 represents that this Switch should not be recognized as the default
router for this link-local network. The user may set a time between
0
and
9000
seconds.
The default setting is
1800
seconds.
RA Reachable Time
This field will set the time that remote IPv6 nodes are considered reachable. In essence,
this is the Neighbor Unreachability Detection field once confirmation of the access to this
node has been made. The user may set a time between
0
and
3600000
milliseconds. The
default setting is
1200000
milliseconds. A very low value is not recommended.
RA Retransmit Time
(ms)
Used to set an interval time between
0
and
4294967295
milliseconds for the dispatch of
router advertisements by this interface over the link-local network, in response to a
Neighbor Solicitation message. If this Switch is set as the default router for this local link,
this value should not exceed the value stated in the Life Time field previously mentioned.
Setting this field to zero will specify that this switch will not specify the Retransmit Time
for the link-local network. (and therefore will be specified by another router on the link-
local network. The default value is
0
milliseconds.
RA Managed Flag
Use the pull-down menu to enable or disable the Managed flag. When enabled, this will
trigger the router to use a stateful autoconfiguration process to get both Global and link-
local IPv6 addresses for the Switch. The default setting is
Disabled
.
RA Other Configure
Flag
Use the pull-down menu to enable or disable the Other Configure flag. When enabled,
this will trigger the router to use a stateful autoconfiguration process to get configuration
information that is not address information, yet is important to the IPv6 settings of the
Switch. The default setting is
Disabled
.
