3.
Specify the VLAN ID for the management VLAN.
The management VLAN is used to establish an IP connection to the switch from a
workstation that is connected to a port in the same VLAN. If not specified, the active
management VLAN ID is 1 (default), which allows an IP connection to be established
through any port.
workstation that is connected to a port in the same VLAN. If not specified, the active
management VLAN ID is 1 (default), which allows an IP connection to be established
through any port.
When the management VLAN is set to a different value, an IP connection can be made
only through a port that is part of the management VLAN. It is also mandatory that the
port VLAN ID (PVID) of the port to be connected in that management VLAN be the same
as the management VLAN ID.
only through a port that is part of the management VLAN. It is also mandatory that the
port VLAN ID (PVID) of the port to be connected in that management VLAN be the same
as the management VLAN ID.
The management VLAN has the following requirements:
•
Only one management VLAN can be active at a time.
•
When a new management VLAN is configured, connectivity through the existing
management VLAN is lost.
•
The management station should be reconnected to the port in the new management
VLAN.
Note:
Make sure that the VLAN to be configured as the management
VLAN exists. And make sure that the PVID of at least one port that is
a port of the VLAN is the same as the management VLAN ID. For
information about creating VLANs and configuring the PVID for a
port, see
a port of the VLAN is the same as the management VLAN ID. For

Click Cancel to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch.
Time
The GS510TP and GS110T switch software supports the Simple Network Time Protocol
(SNTP). You can also set the system time manually
(SNTP). You can also set the system time manually
SNTP assures accurate network device clock time synchronization up to the millisecond.
Time synchronization is performed by a network SNTP server. The GS510TP and GS110T
switch software operates only as an SNTP client and cannot provide time services to other
systems.

Time sources are established by Stratums. Stratums define the accuracy of the reference
clock. The higher the stratum (where zero is the highest), the more accurate the clock. The
device receives time from stratum 1 and above since it is itself a stratum 2 device.

The following is an example of stratums:

Stratum 0: A real-time clock is used as the time source, for example, a GPS system.
