NTP on a HP GbE2c L2/L3 Blade Switch

Date18 Mar 2012 ContentComments

To configure a HP GbE2c L2/L3 Ethernet Blade Switch for HP c-Class BladeSystem, you need to use NTP with the following syntax.

ntp enable 
ntp timezone 0
ntp primary-server <ip>
ntp secondary-server <ip>

The first line enables NTP, the second tells the switch to use GMT+0 and the third/forth tells the switch which servers to sync with.

This needs to be done in configure mode which can be got into via enable mode.

enable
configure

Now ensure the switch timezone is correct, the command for this is slightly obnoxious. Below is an example of setting it to GB:

Switch(config)# system timezone

Switch# conf t
Switch(config)# ntp enable
Switch(config)# ntp timezone 0
Switch(config)# ntp primary-server 79.142.192.4
Switch(config)# ntp secondary-server 217.147.208.1
Switch(config)# exit
Switch# copy run start
Switch# logout

Your switches should now keep their time in sync :)
