Configure an SNTP server

SNTP assures accurate network device clock time synchronization up to the millisecond. Time synchronization is performed by a network SNTP server. The switch operates only as an SNTP client and cannot provide time services to other systems.

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

The following is an example of strata:

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

•

• Stratum 1.

A server that is directly linked to a Stratum 0 time source is used. 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.

The device

Information received from SNTP servers is evaluated based on the time level and server type.

SNTP time definitions are assessed and determined by the following time levels:

•T1. Time that the original request was sent by the client.

•T2.

•T3.

•T4.

Time that the original request was received by the server. Time that the server sent a reply.

Time that the client received the server's reply. The device can poll unicast server types for the server time. Polling for unicast information is used for polling a server for which the IP address is known.

SNTP servers that were configured on the device are the only ones that are polled for synchronization information.

T1 through T4 are used to determine server time. This is the preferred method for synchronizing device time because it is the most secure method. If this method is selected, SNTP information is accepted only from SNTP servers defined on the device using the SNTP Server Configuration page.

The device retrieves synchronization information, either by actively requesting information or at every poll interval.

address is a DNS host name, then that host name is resolved into an IP address each time an SNTP request is sent to it.

9. If the UDP port on the SNTP server to which SNTP requests are sent is not the standard port (123), specify the port number in the Port field.

The valid range is 1 to 65535. The default value is 123.

10. In Priority field, specify the priority order in which the switch must query the servers. The SNTP client on the device continues sending SNTP requests to different servers until

a successful response is received, or all servers are exhausted.

The priority indicates the order in which to the switch must query the servers. The request is sent to an SNTP server with a priority value of 1 first, then to a server with a priority value of 2, and so on. If any servers are assigned the same priority, the SNTP client contacts the servers in the order that they appear in the table. The valid range is 1 to 3. The default value is 1.

By default, supplied power is prioritized in ascending port order, up to the total power budget of the device. If the power requirements for the attached devices exceed the total power budget of the switch, the power to the device on the highest-numbered PoE+ port is disabled to make sure that the devices connected to the higher-priority, lower-numbered PoE+ ports are supported first.

It is important to note that although a device is listed as an 802.3at (PoE+) powered or

802.3af (PoE) powered device, it might not require the maximum power limit that is specified. Many devices require less power the devices correctly report their PoE class to the switch.

Device class power requirements

PoE and PoE+ use Ethernet cables to supply power to PoE-capable devices on the network, such as WiFi access points, IP cameras, VoIP phones, and switches. The switch is compliant with the IEEE 802.3at standard (PoE+) and backward compatible with the IEEE 802.3af standard (PoE). The switch can pass power through to any powered device (PD) that supports these standards. PoE and PoE+ let you power such devices without the need for a separate power supply.

, when

The switch supports a Plug-and-Play process by which it detects the type of device that is connected to one of its PoE+ ports and whether that device needs power and how much so that the switch can provide the correct power to the device.

During the Plug-and-Play process, the connected device can provide its Class response to the switch in many ways, depending on how the vendor programmed the device.

Power allocation and power budget concepts

The switch is a smart switch in that it can allocate the required power to a connected device by using a prioritization scheme: By default, power is supplied in ascending port order (that is, lower port numbers are served first) until the power budget is consumed and insufficient power remains to allocate to the next device. When less than 7W of PoE power is available on a port, the port PoE LED lights yellow, and the attached device does not receive power from the port. However, the switch continues to send data through the port connection.

The switch is also a smart switch in that it can override the IEEE power classification of a powered device (PD): If the PD consumes less power than required by its power classification, the switch provides only the power that the PD consumes instead of the power that is required by the PD’

s power classification.

If some PoE+ ports are in use and deliver power

, you can calculate the available power budget for the other PoE+ ports by subtracting the consumed (that is, delivered power) from the total available power budget. (For information about the total available power budget, see PoE concepts on page 94.)

An example for model GS728TPv2: Port 1 delivers 4.4W to a PD. The available power budget is 185.6W (190W–4.4W).

An example for model GS752TPP: A Class 4 PD is attached to Port 1, a Class 2 PD to Port 2, and another Class 4 PD to Port 3. However, the PDs consume less power than defined by their classes: The PD attached to Port 1 consumes 7.3W, the PD attached to Port 2 consumes 4.7W, and the PD attached to Port 3 consumes 8.9W. So even though the switch provides power to two Class 4 devices and one Class 3 device, if the default power adapter is installed, the available power budget is 739.1W (760W–7.3–4.7–8.9W).
