Subnet Mask This mask identifies the host address
bits used for routing to specific subnets. (Default:
255.255.255.0)
Default Gateway IP address of the gateway router
between this device and management stations that exist
on other network segments. (Default: 0.0.0.0)

Setup > Time
Simple Network Time Protocol (SNTP) allows the Switch
to set its internal clock based on periodic updates from a
time server (SNTP or NTP). Maintaining accurate time on
the Switch enables the system log to record meaningful
dates and times for event entries. If the clock is not set, the
Switch will only record the time from the factory default
set at the last bootup. When the SNTP client is enabled,
the Switch periodically sends a request for a time update
to a configured time server. You can configure up to two
time server IP addresses. The Switch will attempt to poll
each server in the sequence.
