Configuring NTP Server in HP Procurve Switches

Time is important for you to check logs.
This time I'd like to show you how to configure NTP Server in HP Procurve Switches.
HP Switches are only support less secure SNTP instead of NTP.

OK. Let's Configure!

Login to your switch with console/terminal and type following commands for your sntp server configuration.

configure terminal
timesync sntp

sntp unicast (Use this command if you want to use only one NTP server)
(or)
sntp broadcast (Use this command if you want to use more than one NTP server)

sntp server priority 1 218.186.3.36
(or)
sntp server 218.186.3.36
(These above two commands are working on different model.
Some model work first command and some model work second command.
Please take note that you can configure maximum 3 NTP server for your switch.
In my example, I use NTP server for Singapore)

time timezone +480 (Formula for this command is GMT+Regional Time in Minute. I use Singapore Time and GMT+8. 8 hours in minute is 480. So result is GMT+480)

Once you done above all commands, use below command to check NTP Server setting.

show sntp
(or)
show sntp statistics (This command is not working on some switch model)

If NTP server setting are correct, check the time with command "show time".
If Time is showing as expected ,save the configuration with "write memory" command.
Logout from switch then.
If NTP server setting is not correct as what you expected, check all your configuration again.

Hope this post help you on configuratre the SNTP for your switch.

Have a good time.
(Be knowledgeable,pass it on then)

Fortigate guide for Begineer - 6

I would like to explaine how to troubleshoot the Fortigate Unit configured by Transparent Mode in step by step this time. Let's assume, you have one Fortigate Unit that configured as Transparent Mode. But devices from Internal/Private Network unable to access Internet/Public Network through your Fortigate Unit. OK. Let's troubleshoot with following steps, 1) Check the physical network connections between the network and the FortiGate unit, and between the FortiGate unit and the Internet. 2) Check the router and ISP-supplied equipment to make sure it is operating correctly. 3) Verify that you can connect to the internal interface by connecting to the management IP address of the FortiGate unit from the Internal network. From the internal network, attempt to ping the management IP address. If you cannot connect to the internal interface, verify the IP configuration of the PC and make sure the cables are connected and all switches and other devices on the network are powered on a...

Why do we need network virtualization?

We need to think about Server Virtualization first if we want to talk about Network Virtualization. In the era of cloud computing, servers are virtualized and used in Data Centers. We are facing a lot of problem when we virtualized our Servers, 1) Routing and Switching Problem Routing become the issue when we create Virtual Switch and VLANs according to production requirement. Network Team might need some time to change on their end to meet with Server Virtualization Team changes on their end. ၂) Firewall Services Physical Firewall are difficult to manage due to the large number of rules needed to satisfy business requirements. New applications, new projects, and new networks all come with potential security requirements, which impact centralized firewall management. ၃) Load Balancing Let's say your company deploys a new physical load balancer for each tenant, resulting in increased capital expenditures. Once a tenant reaches their maximum capacity, it ca...

Link Aggregating with Synology NAS and Cisco Switch

I’d like to share how to setup Link Aggregating between Synology NAS and Cisco Switch. I’ve got one Synology NAS with 4 Network Ports and I’m going to use 2 of them. Both Network Port to be as one Logical Link, Fault Tolerance and Load Balancing. To do that, I need to configure Link Aggregating on Synology NAS and EtherChannel with LACP on Cisco Switch. Below is brief steps to do to meet with my requirements. - Get connected Synology NAS and Cisco Switch as shown in picture. - Bonding two Network Ports of Synology NAS and assign IP Address - Configure EtherChannel with LACP in Cisco Switch and add two physical ports as Member. OK. Let’s begin from Synology NAS. - Login to the Synology and go to Control Panel>Network>Create>Create Bond - Select IEEE 802.3ad to get Fault Tolerance and Load Balancing Featureyou’re your switch not support 802.3ad you can only select Fault Tolerance only feature). After that click “Next”. - Choose the network port f...
