LevelOne IGP-1271 - 2-1.3 Ntp

is supposed to be uniquely assigned. Once the DAD (Duplicate Address Detection) detects the
address duplication, the operation on the interface SHOULD be disabled.
At this moment, manual intervention is required to resolve the address duplication. For example,
check whether the loop occurs in the VLAN or there is indeed other device occupying the same
hardware address as the device in the VLAN.
After making sure the specific link-local address is unique on the IPv6 link in use, delete and then
add the specific IPv6 interface to restart the IPv6 operations on this interface.
IP Routes
 Delete
Select this option to delete an existing IP route.
 Network
The destination IP network or host address of this route. Valid format is dotted decimal
notationor a valid IPv6 notation. A default route can use the value 0.0.0.0or IPv6 :: notation.
 Mask Length
The destination IP network or host mask, in number of bits (prefix length). It defines how
much of a network address that must match, in order to qualify for this route. Valid values
are between 0 and 32 bits respectively 128 for IPv6 routes. Only a default route will have a
mask length of 0 (as it will match anything).
 Gateway
The IP address of the IP gateway. Valid format is dotted decimal notationor a valid IPv6
notation. Gateway and Network must be of the same type.
 Next Hop VLAN (Only for IPv6)
The VLAN ID (VID) of the specific IPv6 interface associated with the gateway.
The given VID ranges from 1 to 4095 and will be effective only when the corresponding IPv6
interface is valid.
If the IPv6 gateway address is link-local, it must specify the next hop VLAN for the gateway.
If the IPv6 gateway address is not link-local, system ignores the next hop VLAN for the
gateway.

Click to save changes.
 Reset:
Click to undo any changes made locally and revert to previously saved values.
2-1.3 NTP
NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean
Time (GMT). If use the NTP mode and select a built-in NTP time server or manually specify an
user-defined NTP server as well as Time Zone, the switch will sync the time in a short after
pressing <Apply> button. Though it synchronizes the time automatically, NTP does not update
the time periodically without user’s processing.
