If choosing SNTP for the clock source, then the following parameters will be available:

SNTP First Server: Select IPv4 or IPv6 then specify the IP address of primary SNTP server from which the

system time is retrieved.

SNTP Second Server: Select IPv4 or IPv6 then specify the IP address of secondary SNTP server from

which the system time is retrieved.

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.

When selecting Local for the clock source, users can select from one of two options:

Manually Time Settings: Users input the system Date and Time manually.

L2 Functions > LLDP > LLDP Global Settings

LLDP (Link Layer Discovery Protocol) supports an IEEE 802.1AB standard-based method for switches. This

function allows the switches to advertise themselves to the neighboring devices and learn about the

neighboring LLDP devices. The Switch will store that information in the Management Information Base (MIB);

SNMP utilities can learn about the network topology by getting the MIB information from each LLDP device.
