IME ONFIGURATION
In the System menu, click on Time Configuration (see Table 4-5).The switch provides manual and automatic
ways to set the system time via NTP*. The manual setting is simple—just type in the year, month, day, hour,
minute, and second within the valid value range indicated in each item. If you type in an invalid value (for
example, 61 in minutes), the switch changes the figure to 59.
*NTP is a well-known protocol used to synchronize the switch system time clock over a network. NTP, an Internet draft standard formalized in
RFC 1305, has been adopted on the system as version 3 protocol. The switch provides four built-in NTP server IP addresses residing in the
Internet and a user-defined NTP server IP address. The time zone is Greenwich-centered (Greenwich Mean Time or GMT), using the form
GMT+/- xx hours.
Table 4-4 (continued). IP Configuration screen options.
Subnet mask sets the subnet mask value, which should be the same
value as that of the other devices residing in the same network that
the switch is attached to. For more information, see Section 3.5.
Default: 255.255.255.0
Set an IP address for a gateway to handle those packets that do not
meet the routing rules predefined in the device. If a packet does not
meet the criteria for another pre-defined path, it must be forwarded to
a default router on a default path. This means any packet with an
undefined IP address in the routing table will be sent to this device
unconditionally.
Default: 192.168.1.254
Domain Name Server translates the IP address and name address.
The switch supports the DNS client function to re-route the
mnemonic name address to the DNS server to get its associated IP
address for accessing the Internet. Specify a DNS IP address for the
switch. With this, the switch can translate a mnemonic name address
into an IP address.
There are two ways to specify the DNSIP address. Fixed mode
manually specifies its IP address, and dynamic mode is assigned by
the DHCP server while DHCP is enabled. DNS can help you easily
remember the mnemonic address name with meaningful words. The
default is no DNS address assignment.
Default: 0.0.0.0
