Aruba Switch NTP (Network Time Protocol) Configuration
NTP (Network Time Protocol) is time
management protocol.
NTP (Network Time Protocol) for network time
managing we use this in our organization because 100- 1000 devices are running
in a network then it’s very difficult to manage time on all devices that’s why
we use this mechanism. It uses port no 123 for transport and use UDP services
for polling time from server to the devices.
NTP uses operate different modes. Supports four different modes.
1-Client
2-Server
3-Peer
4-Broadcast/multicast.
1-Client

4-Broadcast/multicast.
NTP
(Network Time Protocol) operating modes define the NTP communication between
NTP devices. NTP communication between two different devices includes NTP Time
requests and NTP control queries. NTP Time request communication is the request
from an NTP client for time synchronization from an NTP server. NTP Control queries
are the communication messages for configuration information.
Following
are the important NTP operating modes:
1-Client: An NTP client is a network
device which is configured to let its clock synchronized from an external NTP
Time Server. NTP Client mode devices will not provide synchronization services
to other network infrastructure devices.
2-Server: An NTP server is a network device which is running NTP service
and configured to provide Time information to NTP clients using NTP. NTP
servers provide only Time information to NTP Clients and will never accept time
synchronization information from other devices.
3-Peer: NTP peers does not have authority over the other. NTP peer mode,
each device can provide time synchronization to the other.
4-Broadcast/multicast: In Broadcast/multicast mode, the NTP server broadcasts/multicasts
the time synchronization information to all NTP clients.
In this mode you can run only troubleshooting
command but cannot run modification command if you want to change in switch.
Need to go first in configure mode then can execute modification command.
Aruba-tech#
Aruba-tech# configure
This command is use for NTP tries to adjust the clock in
small steps and will continue until the client gets the accurate time.
Aruba-tech(config)#timesync ntp
This command use for sending synchronization packet
to only NTP configured device with the server address.
Aruba-tech(config)#ntp unicast
We define NTP server by giving IP address of NTP
server.
Aruba-tech(config)#ntp server 10.12.1.25 iburst
also need to adjust time according to location.
Aruba-tech(config)#time timezone 330
After confirgured complete NTP configuration then
need to enable NTP for this device. We will have to give this command.
Aruba-tech(config)#ntp enable
timesync ntp
ntp unicast
ntp server 10.12.1.25 iburst
ntp enable
time timezone 330

This is configuration for NTP of Aruba switch. This
switch has lots of excellence feature. I will update all feature which require
in our network.
