ProSAFE FS526Tv2, FS726Tv2, and FS728TLP Smart Switches Change the Management VLAN Use the management VLAN to establish an IP connection to the smart switch from a computer that is connected to a port in the same VLAN. If not specified, the active management VLAN ID is 1 (the default VLAN ID), which allows an IP connection to be established through any port. Only one management VLAN can be active at a time. If you configure the management VLAN to be different from 1, you can make an IP connection only through a port that is part of the management VLAN. The port VLAN ID (PVID) of the port in the management VLAN needs to be the same as the ID of the management VLAN. For information about creating VLANs and configuring the PVID for a port, see Configure VLANs on page 80.  To change the management VLAN: 1. Select System > Management > IP Configuration. The IP Configuration screen displays. 2. Specify the VLAN ID for the management VLAN. The VLAN ID needs to be in the range from 1 to 4093. Make sure that the VLAN that you configure as the management VLAN exists, and make sure that the PVID of at least one port that is member of the VLAN has the same ID as the management VLAN. 3. Click the Apply button. The settings are saved. Connectivity to the smart switch through the existing management VLAN is lost. 4. Reconnect your computer to a port in the new management VLAN. Configure the Time Settings and SNTP Servers The smart switch supports the Simple Network Time Protocol (SNTP). You can also set the system time manually. SNTP assures accurate network device clock time synchronization up to the millisecond. A network SNTP server performs time synchronization. The smart switch operates only as an SNTP client and cannot provide time services to other systems. Strata provide time sources and define the accuracy of the reference clock. The higher the stratum (where o [zero] is the highest), the more accurate the clock. The smart switch receives time from stratum 0 or stratum 1 since it is itself a stratum 2 device. The following is an example of stratums: • Stratum 0. The time source is a real-time clock such as a GPS time system. • Stratum 1. The time source is a server that is directly linked to a stratum 0 time source. Stratum 1 time servers provide primary network time standards. • Stratum 2. The time source is distanced from the stratum 1 server over a network path. For example, a stratum 2 server receives the time over a network link, through NTP, from a stratum 1 server.

ProSAFE FS526Tv2, FS726Tv2, and FS728TLP Smart Switches
Change the Management VLAN
Use the management VLAN to establish an IP connection to the smart switch from a
computer that is connected to a port in the same VLAN. If not specified, the active
management VLAN ID is 1 (the default VLAN ID), which allows an IP connection to be
established through
any
port. Only one management VLAN can be active at a time.
If you configure the management VLAN to be different from 1, you can make an IP
connection only through a port that is part of the management VLAN. The port VLAN ID
(PVID) of the port in the management VLAN needs to be the same as the ID of the
management VLAN. For information about creating VLANs and configuring the PVID for a
port, see
Configure VLANs
on page
80.
To change the management VLAN:
1.
Select
System > Management > IP Configuration
.
The IP Configuration screen displays.
2.
Specify the VLAN ID for the management VLAN.
The VLAN ID needs to be in the range from 1 to 4093. Make sure that the VLAN that you
configure as the management VLAN exists, and make sure that the PVID of at least one
port that is member of the VLAN has the same ID as the management VLAN.
3.
Click the
Apply
button.
The settings are saved. Connectivity to the smart switch through the existing
management VLAN is lost.
4.
Reconnect your computer to a port in the new management VLAN.
Configure the Time Settings and SNTP Servers
The smart switch supports the Simple Network Time Protocol (SNTP). You can also set the
system time manually.
SNTP assures accurate network device clock time synchronization up to the millisecond. A
network SNTP server performs time synchronization. The smart switch operates only as an
SNTP client and cannot provide time services to other systems.
Strata provide time sources and define the accuracy of the reference clock. The higher the
stratum (where o [zero] is the highest), the more accurate the clock. The smart switch
receives time from stratum 0 or stratum 1 since it is itself a stratum 2 device.
The following is an example of stratums:
•
Stratum 0
. The time source is a real-time clock such as a GPS time system.
•
Stratum 1
. The time source is a server that is directly linked to a stratum 0 time source.
Stratum 1 time servers provide primary network time standards.
•
Stratum 2
. The time source is distanced from the stratum 1 server over a network path.
For example, a stratum 2 server receives the time over a network link, through NTP, from
a stratum 1 server.
