PC Time
Visitor's own PC, display and switch itself does not matter.
Notes:
NTP server can be empty, the device using the own server update, but must use the
correct DNS and gateway.
NTP server must have a valid host name or a valid IP address.
Only the Administrators have permission to manually configure the device time.
Time zones must be configured; either uses the "local time" or "NTP time.
The configuration of the NTP server or PC can cause the display is not normal, you can
change the time display format to adjust the display.
13.3 Device address
Device address
Device configuration support two modes, DHCP and static IP address, can get the
device’s IP address via client when the DHCP function is running, if you need NTP
that need to connect internet, please enter the available and correct gateway and
DNS address.
IP Address
IP address is a address of 32 bits length which is assigned to the device on the
internet. The IP address consists of two fields: the network number field (net-id) and
the Host ID field (host-id). For can conveniently manage IP address, IP addresses
are divided into five categories.
Subnet Mask
Mask is corresponding 32 bits number of IP address. Some are 1, the others are 0.
These 1 and 0 can be combined arbitrary in principle, but the first continuous bits
are 1 when designing subnet mask. IP address can be divided into 2 parts by subnet
mask: subnet address and host address. 1 in IP address and subnet corresponds to
subnet address, other bits are host address. A type of address corresponding mask
is 255.0.0.0; mask of B type address is 255.255.0.0; mask of C type address is
255.255.255.0.
Default Gateway
Default gateway in the host PC is generally called default route. Default route refer
to a kind of router that destination address of IP data packet will choose when it
