Aruba Switch 2930 Series NTP (Network Time Protocol) Configuration


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.

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


Aruba-tech# show  ntp associations detail
Aruba-tech# show  ntp associations
Aruba-tech# show  ntp authentication
Aruba-tech# show  ntp servers
Aruba-tech# show  ntp
Aruba-tech# show  ntp status

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.

DHCP-Snooping Configuration with Aruba Switch Series 2930, 2530.

  DHCP-Snooping Configuration with Aruba Switch Series 2930, 2530. DHCP Snooping  is a Layer 2 security switch feature which blocks unauthorized (rogue) DHCP servers from distributing IP addresses to DHCP clients also call option 82 of this service. This lab configuration with Aruba Switch Series 8320, 2930. We need trusted DHCP server IP address to configure DHCP-snooping on your network.   DHCP Starvation   attack  is a common network attack that targets network  DHCP servers . Its primary objective is to  flood  the organization’s DHCP server with  DHCP REQUEST messages  using  spoofed source MAC addresses . The DHCP server will respond to all requests, not knowing this is a  DHCP Starvation attack , and assign available IP addresses until its  DHCP pool is depleted . At this point the attacker has rendered the organization’s DHCP server useless and can now enable his own  rogue DHCP server  to s...

Aruba Switch 2930F 48G Poe Basic Configuration

Aruba Switch 2930F 48G Poe Basic Configuration First You need a console cable to configure a switch. Console is an interface. Via this interface we can execute any command.     After connect this cable with switch to laptop. Need to open console (Putty).   You can download from this link  https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html When will get console of fresh switch. you will get with this little default configuration ; JL256A Configuration Editor; Created on release #WC.16.07.0005 ; Ver #14:21.4f.f8.1d.9b.3f.bf.bb.ef.7c.59.fc.6b.fb.9f.fc.ff.ff.37.ef:22 hostname "Aruba 2930f" module 1 type jl256a vlan 1    name "DEFAULT_VLAN"    no untagged 1-48    untagged 49-50,Trk1    no ip address    ipv6 address dhcp full    exit Now you need to configure fresh switch according to your requirement. ...
