Chapter 11: Simple Network Time Protocol (SNTP) Client
246
Section II: Basic Operations
Overview
The switch has an Simple Network Time Protocol (SNTP) client for setting
its date and time from an SNTP or NTP server on your network or the
Internet. The date and time are added to the event messages that are
stored in the event log and sent to syslog servers.
The switch polls the SNTP or NTP server for the date and time when you
configure the client and when the unit is powered on or reset.
Here are the guidelines to using the SNTP client:
You must specify the IP address of the SNTP or NTP server from
which the switch is to obtain the date and time. You can specify only
one IP address. For instructions, refer to “Activating the SNTP Client
and Specifying the IP Address of an NTP or SNTP Server” on
page 247.
You must configure the client by specifying whether the locale of the
switch is in Standard Time or Daylight Savings Time. For instructions,
refer to “Configuring Daylight Savings Time and UTC Offset” on
page 248.
You must specify the offset of the switch from Coordinated Universal
Time (UTC). For instructions, refer to “Configuring Daylight Savings
Time and UTC Offset” on page 248.
The switch must have a management IP address to communicate with
a SNTP or NTP server. For instructions, refer to “Adding a
Management IP Address” on page 66 or Chapter 9, “IPv4 and IPv6
Management Addresses” on page 207.
The SNTP or NTP server must be a member of the same subnet as
the management IP address of the switch or be able to access it
through routers or other Layer 3 devices.
If the management IP address of the switch and the IP address of the
SNTP or NTP server are members of different subnets or networks,
you must also assign the switch a default gateway. This is the IP
address of a routing interface that represents the first hop to reaching
the remote network of the SNTP or NTP server. For instructions, refer
to “Adding a Management IP Address” on page 66 or Chapter 9, “IPv4
and IPv6 Management Addresses” on page 207.
