6.4.2 Time - SNTP
To enable or disable the SNTP time function or set daylight savings time, choose System-->Time-->SNTP.
SNTP (Simple Network Time Protocol) is a simplified version of NTP which is an Internet protocol used to
synchronize the clocks of computers to a specified time reference. Because time typically advances, the time on
various node stations will be different. For the communicating programs running on those devices, this causes time
to jump forward and backward—an undesirable effect. Therefore, the switch provides comprehensive mechanisms
to access national time and frequency dissemination services, and organize the time-synchronization subnet and
the local clock in each participating subnet peer.
Daylight saving time (DST) is the convention of advancing clocks so that afternoons have more daylight and
mornings have less. Typically, clocks are adjusted forward one hour near the start of spring and are adjusted back
an hour in autumn.
Figure 20 SNTP Page
SNTP Client Enable or disable the SNTP function to get the time from the SNTP server. When
enabled, the SNTP client uses the service from the SNTP server and the system time
will follow the SNTP server. When disabled, local time is used without any SNTP
server information.
NOTE when SNTP is enabled, a network connection between the 2080E-T
switch and the SNTP server is required for the SNTP client within the switch
to receive and synchronize time information to the time provided by the
SNTP server.
UTC Timezone Universal Time Coordinated. Sets the local time zone for the switch location. See
Table 1 for a list of time zones.
SNTP Sever Address Sets the SNTP server IP address. You can enter the IP address of a local network
time server or an Internet time server.
Daylight Saving Time Allows you to enable or disable the Daylight Saving Period and Daylight Saving
Offset settings. When enabled, the Daylight Savings settings are in effect, and when
disabled, these settings are ignored.
Daylight Saving
Period
Sets the daylight saving beginning date and time and ending date and time. Enter

6.4.4 IP Addressing – IPV4
The 2080E-T Switch needs to be assigned an IP address that identifies it on the network. You can select a method
of assigning IP address to the switch by choosing System-->IP Addressing-->IPV4.
DHCP Client Enable or disable the DHCP client function. When the DHCP client function is
enabled, the switch will automatically obtain an IP address from the network DHCP
server. The default IP address will be replaced by the assigned IP address from the
DHCP server. After you click Apply, a message informs you that when the DHCP
client is enabled the current IP address will be lost and you will need to find the new
IP obtained from the DHCP server.

IP Address Enter a static IP address to the switch from the subnet address range that the
network is using. If the DHCP Client option is enabled, the switch is configured as a
DHCP client. The network DHCP server will assign the IP address to the switch and
the switch displays it in this column. The default IP address is 192.168.1.88. You can
also choose an IP address manually when the DHCP Client option is disabled.
Subnet Mask Enter the subnet mask of the IP address. You need to specify the subnet mask if the
DHCP Client option is disabled.
Gateway Enter the network gateway for the switch. You need to specify the gateway if the
DHCP Client option is disabled. The default gateway address is 192.168.1.254.

6.4.5 Syslog
Syslog Configuration
The Syslog (system event log) may be sent to the client only, server only, or both the client and server. The type of
events that are issued to the client or server depends on the system event selection on the System Alert - Event
page (see “System Alert Event”).
To configure the Syslog, choose System-->Syslog-->Configuration.
Figure 23 Syslog Configuration Page
Syslog Mode Select the system log mode:
• Client Only—The system event log will only be sent to this interface of the
switch.
• Server Only—The system event log will only be sent to the remote system log
server with its IP address assigned.
• Both—The system event log will be sent to the remote server and this interface.
• Disable—No system event log is generated or sent.
