4 Web-based Switch Configuration
Clock Source: Specifies the clock source by which the system time is set. The possible options are:
Local - Indicates that the system time is set locally by the device.
SNTP - Indicates that the system time is retrieved from a SNTP server.
Current Time: Displays the current date and time for the switch.
If choosing SNTP for the clock source, then the following parameters will be available:
SNTP First Server: Selectable IPv4 address, IPv6 address or Domain Name.
SNTP Second Server: Selectable IPv4 address, IPv6 address or Domain Name.
SNTP Poll Interval in Seconds (30-99999): Defines the interval (in seconds) at which the SNTP server is
polled for Unicast information. The Poll Interval default is 30 seconds.

L2 Functions > LLDP > LLDP Global Settings
LLDP (Link Layer Discovery Protocol) provides IEEE 802.1AB standards-based method for switches to
advertise themselves to neighbor devices, as well as to learn about neighbor LLDP devices. SNMP utilities
can learn the network topology by obtaining the MIB information in each LLDP device. The LLDP function is
enabled by default.
