Chapter 6: Network Time Protocol Commands
118
Overview
The AT-S97 Management Software has a Network Time Protocol (NTP)
client so that it can set its internal clock and calender from an NTP server
on your network or the Internet. It adds the date and time to the events
stored in the event log and to SNMP traps.
The commands described in this chapter control the NTP client. The client
is activated and deactivated with the NTP ENABLE command and the
NTP DISABLE command, and the IP address of the NTP server is
specified with the NTP SET command.
To manually set the date and time, refer to “SYSTEM SET CLOCK” on
page 60.
NTP Client
Guidelines
The guidelines to using the NTP client are:
ˆ The AT-MCF2000M Management Module must have an IP
configuration, as explained in Chapter 3, “IP Configuration
Commands” on page 47.
ˆ The 10/100/1000Base-T Management port on the management
module must be connected to a device on your network, such as a
Fast Ethernet or Gigabit Ethernet switch. The module communicates
with the NTP server through this port.
ˆ The NTP server must be a member of the same network as the
management module or have access to it through Layer 3 routing
devices.
ˆ If the management module and the NTP server are on different
networks, the IP configuration on the module must include a default
gateway address specifying the IP address of the routing interface of
the first hop to reaching the remote server. For instructions, refer to
Chapter 3, “IP Configuration Commands” on page 47.
ˆ Before you enable the NTP server with the NTP ENABLE command,
connect the chassis to an NTP server.
